Safety Information

Every radio, when transmitting, radiates energy into the atmosphere which may, under certain conditions, cause the generation of a spark.

All users of vehicles fitted with radios should be aware of the following warnings:

Do not operate radio near flammable liquids or in the vicinity of explosive devices.

To ensure personal safety, please observe the following simple rules:

Check

the laws and regulations on the use of two-way mobile radios in the areas where you drive. Always obey them. Also, when using your radio while driving, please:

•

Give full attention to driving,

•

Use hands-free operation, if available and

•

Pull off the road and park before making or answering a call if driving conditions so require.

Airbag Warning

Installation of vehicle communication equipment should be performed by a professional installer/technician qualified in the requirements for such installations.

An air bag’s size, shape and deployment area can vary by vehicle make, model and front compartment configuration (e.g., bench seat vs. bucket seats). Contact the vehicle manufacturer’s corporate headquarters, if necessary, for specific air bag information for the vehicle make, model and front compartment configuration involved in your communication equipment installation.

LP Gas Warning

It is mandatory that radios installed in vehicles fuelled by liquefied petroleum gas conform to the National Fire Protection Association standard NFPA 58, which applies to vehicles with a liquid propane (LP) gas container in the trunk or other sealed off space within the interior of the vehicle. The NFPA58 requires the following:

•

Any space containing radio equipment shall be isolated by a seal from the

VEHICLES EQUIPPED WITH AIR BAGSAn air bag inflates with great force. DO NOT place objects, including communication equipment, in the area over the air bag or in the air bag deployment area. If the communication equipment is improperly installed and the air bag inflates, this could cause serious injury.

Revision B, 5/98 Safety 1

space in which the LP gas container and its fittings are located.

•

Removable (outside) filling connections shall be used.

•

The container space shall be vented to the outside.

Anti-Lock Braking System (ABS) and Anti-Skid Braking System Precautions

Disruption of the anti-skid/anti-lock braking system by the radio transmitter may result in unexpected vehicle motion.

Motorola recommends the following radio installation precautions and vehicle braking system test procedures to ensure that the radio, when transmitting, does not interfere with operation of the vehicle braking system.

Installation Precautions

1. Always provide as much distance as possible between braking modulator unit and radio, and between braking modulator unit and radio antenna and associated antenna transmission line. Before installing radio, determine location of braking modulator unit in vehicle. Depending on make and model of vehicle, braking modulator unit may be located in trunk, under dashboard, in engine compartment, or in some other cargo area. If you cannot determine location of braking modulator unit, refer to vehicle service manual or contact a dealer for the particular make of vehicle.

2. If braking modulator unit is located on left side of the vehicle, install radio on right side of vehicle, and conversely.

3. Route all radio wiring including antenna transmission line as far away as possible from braking modulator unit and associated braking system wiring.

4. Never activate radio transmitter while vehicle is in motion and vehicle trunk lid is open.

Braking System Tests

The following procedure checks for the most common types of interference that may be caused to vehicle braking system by a radio transmitter.

1. Run vehicle engine at idle speed and set vehicle transmission selector to PARK. Release brake pedal completely and key radio transmitter. Verify that there are no unusual effects (visual or audible) to vehicle lights or other electrical equipment and accessories while microphone is NOT being spoken into.

2. Repeat step 1. except do so while microphone IS being spoken into.

3. Press vehicle brake pedal slightly just enough to light vehicle brake light(s). Then repeat step 1. and step 2.

4. Press the vehicle brake pedal firmly and repeat step 1. and step 2.

5. Ensure that there is a minimum of two vehicle lengths between front of vehicle and any object in vehicle’s forward path. Then, set vehicle

transmission selector to DRIVE. Press brake pedal just far enough to stop vehicle motion completely. Key radio transmitter. Verify that vehicle does not start to move while microphone is NOT being spoken into.


7. Release brake pedal completely and accelerate vehicle to a speed between 15 and 25 miles/25 and 40 kilometers per hour. Ensure that a minimum of two vehicle lengths is maintained between front of vehicle and any object in vehicle’s forward path. Have another person key radio transmitter and verify that vehicle can be braked normally to a moderate stop while microphone is NOT being spoken into.


9. Release brake pedal completely and accelerate vehicle to a speed of 20 miles/30 kilometers per hour. Ensure that a minimum of two vehicle lengths is maintained between front of vehicle and any object in vehicle’s forward path. Have another person key radio transmitter and verify that vehicle can be braked properly to a sudden (panic) stop while microphone is NOT being spoken into.


11. Repeat step 9. and step 10. except use a vehicle speed of 30 miles/50 kilometers per hour.

This chapter provides theory of operation information for the radio. It starts with a block diagram level functional description of the entire radio. This is followed by a detailed functional description for each of the four major functions of the radio.

Introduction

The radio is composed of the following four major functions:

•

Receiver

•

Transmitter

•

Dc Power Control and Regulation

•

Operator Interface (Control Head)

The receiver, transmitter, and dc power control and regulation functions are all located on a single circuit card assembly (CCA) in the main body of the radio. The CCA is called the transceiver board. The operator interface function consists of the control head, which plugs into the main body of the radio. There are three different control head types: the Model I for the Model I Radio; the Model II for the Model II Radio; and the Model III for the Model III Radio. The three control heads are covered in their entirety in Volume 1 of this service manual.

The transceiver board in the main body of the radio is physically separated into six functional sections as follows:

•

Receiver Front End

•

Receiver Intermediate Frequency (IF)

•

Receiver Back End

•

Power Amplifier (PA)

•

Synthesizer

•

Controller

The controller section is further divided into two sub-sections: main controller; and power control. The mechanical layout of the transceiver board is illustrated in Chapter 4.

Separate component location diagrams, parts lists, and schematic diagrams are provided in this service manual for each of the six physical sections of the transceiver board and for the control heads.

6 Theory of Operation Revision B, 5/98

The component location diagrams, parts lists, and schematic diagrams for the controller section of the transceiver board and for the three types of control heads are located in Volume 1 of this service manual. The component location diagrams, parts lists, and schematic diagrams for the other five physical sections of the transceiver board are located in this volume (Volume 2d).

Block Diagram Level Theory of Operation

The following discussion refers to the functional block diagram for the radio, Figure 1.

The receiver function of the radio detects, demodulates, amplifies, and outputs via the loudspeaker, radio signals picked up by the vehicle or fixed-station antenna. The radio signal input reaches the receiver from the antenna via the antenna switch, which is located in the transmit-ter function of the radio. The radio signals picked up by the antenna are signals that have been re-broadcast by trunked or conventional repeaters, or that have been broadcast directly by other mobile or fixed station radios.

The receiver function of the radio consists of: the receiver front end section; the receiver intermediate frequency (IF) amplifier section; the receiver back end section; and the audio signal filter (ASFIC) and receiver audio power amplifier circuits in the controller section.

The receiver function of the radio uses the double conversion super-heterodyne design to optimize image rejection and selectivity. The receiver front end section converts the receiver input signal to a first IF of 73.35 MHz. The frequency upon which the receiver operates is determined by a first local oscillator signal generated by the synthesiz-er section. For the purpose of this discussion, the synthesizer section is considered to be part of the transmitter function of the radio.

The 73.35 MHz IF output signal from the receiver front end section passes through the receiver IF amplifier section where it is filtered and amplified. The output of the receiver IF amplifier section goes to the receiver back end section. In the receiver back end section, which contains the zero intermediate frequency (ZIF) integrated circuit (IC), the receiver IF signal is demodulated to produce receiver audio and squelch signals.

The receiver audio and squelch signal outputs from the receiver back end section are processed by the audio signal filter integrated circuit (ASFIC) in the controller section of the radio to generate receiver audio (filtered) and squelch detect signals. The filtering characteristics and other processes of the ASFIC are controlled by the central processor unit in the controller section.

The receiver audio signal (filtered) from the output of the ASFIC goes to the input of the receiver audio power amplifier circuit, which is located in the controller section of the radio. The receiver audio power amplifier circuit does not pass the receiver audio signal to the loud-speaker until it receives an audio PA enable signal from the controller section of the radio. The reason is that the receiver portion of the radio includes a squelch function, which prevents receiver noise from pass-ing to the loudspeaker during periods of no signal reception.

Figure 1 . 900-MHz Radio Functional Block Diagram


The controller generates the audio PA enable signal based on such variables as the level of the received signal, the frequency channel, and the operating mode of the radio. When the audio PA enable signal is generated, the audio power amplifier (PA) is activated and passes the receiver audio signal to the loudspeaker.

The transmitter function of the radio produces either a 12-Watt or a 30-Watt radio frequency output signal, depending on the model of the radio. The radio frequency output signal is frequency modulated by an audio signal from the microphone or from another source such as a telephone keypad or handset.

The transmitter function of the radio consists of: the audio signal filter integrated circuit (ASFIC) in the controller section; the synthesizer section; and the transmitter power amplifier (PA) section. The ASFIC develops a modulation signal by amplifying an audio signal from the microphone, keypad, or handset. The synthesizer section generates a radio frequency carrier signal upon which the transmitter portion of the radio operates.The radio frequency carrier signal generated by the synthesizer section is frequency modulated in the synthesizer section by the modulation signal output from the ASFIC.

The frequency modulated output signal from the synthesizer section is amplified to the required 12-Watt or 30-Watt power level by the power amplifier (PA) section.The output of the PA section passes through the antenna switch and is radiated by the vehicle antenna or fixed-station antenna.

The controller section of the radio contains a microprocessor that controls the radio in accordance with its built in programming as well as commands input manually by the radio operator. The radio operator inputs manual commands to the controller section using the pushbuttons and other controls located on the control head. In addition to its controlling functions, the controller section provides audio amplification of the audio output signal in the receiver function. It also contains squelch detect circuitry based on a buffered discriminator signal from the Zero Intermediate Frequency Integrated Circuit (ZIF IC).

The operator interface function of the radio consists of: a microphone or the microphone portion of a telephone handset; a telephone keypad if used; the pushbuttons and other controls on the control head; and the digital and graphics displays on the control head. The pushbuttons and other controls on the control head provide digital commands to the controller section, and in some instances, hardwired commands to controlled circuits. The digital and graphics displays receive display data from the controller section. The control head contains its own microprocessor, which communicates with the controller section of the radio via an SB9600 serial digital data bus.

The DC power control and regulation function regulates and distributes to the various sections of the radio, DC power from the vehicle battery or fixed station power supply.


ReceiverDetailed Functional Description

The portion of the receiver function that is not part of the controller section of the radio is composed of three sections: receiver front end; receiver If, and receiver back end.

Receiver Front End(All Kits)

The following discussion is based on the schematic diagram for the receiver front end section on page 37. The received RF signal (RX_IN) from the antenna switch in the PA section of the radio enters the first bandpass filter FL6250. The first bandpass filter has three poles, a 938-MHz center frequency, a 6-MHz wide passband, and a 45-dB ultimate rejection for frequencies outside the passband.

After the first bandpass filter, the received RF signal goes to a pair of hot carrier limiting diodes (CR6250). The hot carrier diodes limit strong signals to prevent them from over driving and damaging RF preamplifier Q6271.

The main purpose of RF preamplifier Q6271 is to set the noise figure of the receiver. Q6271 is actively biased through Q6272. During transmit, the RF preamplifier is shut off by the K9.1 line via switch Q6250 and bias transistor Q6272. After the signal leaves the RF preamplifier, it enters second bandpass filter FL6251, which is identical to FL6250.

When the RF signal leaves the second bandpass filter, it goes into mixer U6251. The mixer is the double balanced active Gallium Arsenide type. The RF signal is applied to the mixer through balun transformer T6251. The first injection local oscillator is applied to the mixer via balun transformer T6252 and is 73.35 MHz below the RF signal frequency. The bias for the mixer is set by resistors R6285, R6286, and R6287. The IF output signal from the mixer, which is at a frequency of 73.35 MHz, is fed to the receiver IF section as IF_OUT through transformer T6253.

Receiver Intermediate Frequency (IF)(Kits FLF5591A, B, C; FLF5592A, B, C; HUF1190A; HUF1191A)

The following discussion is based on the schematic diagram for the receiver IF section on page 39.

The IF_OUT signal from the receiver front end section enters the receiver IF section as the IF_IN signal. The first circuit in the receiver IF section is a resistive pad (R6376, R6377, R6378, R6392), which stabilizes the impedance presented to the output of the mixer in the receiver front end section. It also stabilizes the impedance presented to the input of the first 73.35-MHz crystal filter, Y6376.

From the resistive pad, the signal passes through to the first 73.35-MHz crystal filter, Y6376 whose surrounding components match it to 50-ohms and to the input of IF amplifier Q6388. A matching network, which follows Q6388, matches the IF amplifier output impedance to the input impedance of the second 73.35-MHz crystal filter, Y6377. Both crystal filters have two-poles and have a bandwidth of 13kHz to accommodate the bandwidth requirements for digital data. Matching elements, which follow the second crystal filter, match the output of the second crystal filter to the input of the receiver back end section. The signal out of the receiver IF section (IF_V_OUT) passes through


connector J6400 and jumper plug J6401 to the input of the receiver back end section.

Receiver IF(Kits FLF5604A, FUF5752A, FLF5952A, FLF5606A)

The following discussion is based on the schematic diagram for the receiver IF section on page 41.

The IF output signal (IF_OUT) from the receiver front end section enters the receiver IF section as IF_IN and passes into three automatic gain control (AGC)/attenuator stages. The first AGC/attenuator stage is formed by diodes CR6251 and CR6253 and the associated circuitry, the second stage by CR6252, CR6254, and the associated circuitry, and the third stage by CR6255, CR6256 and the associated circuitry.

The three attenuators are controlled by the radio signal strength indicator (RSSI) signal, from the zero intermediate frequency integrated circuit (ZIF IC), in the receiver back end section, via a DC shift and integrator circuit formed by two of the operational amplifiers in U6202. For the lowest level IF_IN signals, the attenuator stages attenuate minimally. For the highest level signals, they attenuate approximately 25dB per stage. The attenuator stages are designed for minimum VSWR, which means that for any level of operation they present a matched port to the surrounding circuitry.

The principle of operation for the attenuator stages, taking the first stage as an example, is the followings: The main components in the attenuator are the two diodes, CR6251 and CR6253. The attenuator is biased by two lines, a constant +5V line, connected to the anode of diode CR6253, and a control line driven by the RSSI signal via the operational amplifiers in U6202.

For a high signal level, the attenuation is at maximum value because the control line is at 0V, which causes CR6251 to be zero biased while CR6253 is maximum biased. This makes the IF signal flow to ground through R6366, C6367 (which acts as a DC block), CR6253, and C6372 (which is also a DC block). The input signal sees a 50-ohm match, which is roughly the sum of the impedances formed by the above mentioned components.

For low signal levels, the attenuation is at minimum value because the control line is at +5V and CR6251 is maximum biased while CR6253 is zero biased. The DC return for the control line is through R6368 and R6370. The large values (470K) of these two resistors makes them also function as RF blocks.

The control line is driven by the RSSI signal line from the ZIF IC in the receiver back end section. The RSSI signal is amplified and DC shifted through one of the operational amplifiers of U6202 and the associated circuitry formed by resistors R6342 through R6345. This then passes though the inverting integrator formed by another operational amplifier of U6202 and C6362, R6358, R6359, R6360 and R6361. The result is that for the lowest RSSI voltage, the control line is +5V and for the highest RSSI voltage, the control line is 0V.

The inherent insertion loss of these attenuators ensures that a good match is presented to the output of the front-end mixer.


The third attenuator stage formed by CR6255 and CR6256 is optional and is bypassed by R6357 with C6366 and R6350 not being placed.

Receiver Back End(All Kits)

The following discussion is based on the schematic diagram for the receiver back end section: page 43 for kits FLF5591A, B, C and FLF5592A, B, C; page 45 for kits FLF5604A, FUF5752A, FLF5952A, and FLF5606A; and page 47 for kits HUF1190A and HUF1191A. From the output of the receiver IF section, the IF signal (IF_IN) enters IF amplifier Q6203. A pair of hot carrier limiter diodes (CR6203) at the base of the IF amplifier protect U6201, the Zero Intermediate Frequency Integrated Circuit (ZIF IC), from strong signal overloading.

With kits FLF5591A, B, C and FLF5592A, B, C, the output of IF amplifier Q6203 is fed to a shunt pin diode attenuator, CR6203. The attenuation provided by the pin diode attenuator is a function of the signal level detected by the internal automatic gain control (AGC) circuit in the ZIF IC. As the RF level increases, the attenuation increases. This ensures that the ZIF IC, whose dynamic range is much less than that of the radio, is not over driven by strong signals, causing distortion in the detected signal.

With kits FLF5604A, FUF5752A, FLF5952A, and FLF5606A, this attenuation function is performed by the attenuator stages in the receiver IF section and this ACG mechanism in the receiver back end section is bypassed. To do this, shorting resistor R6224 is mounted bypassing CR6203, which is not mounted, an additional shorting resistor is placed on the pads of L6208 instead of the 1 microHenry inductor, and CR6204 is not placed.

At the output of Q6203, there is a notch filter, for the third harmonic of 73.35 MHz, made up of components C6249 and inductor L6207. Transistor Q6201 and varactor diode CR6201 form the second local oscillator (LO). The LO operates as a voltage controlled oscillator (VCO), which is controlled by the ZIF IC.

The ZIF IC is a down converter, a filter, a limiter, and an FM demodulator. The IF signal going into the ZIF IC at 73. 35MHz is down converted, filtered, limited, and demodulated. Demodulated audio comes out of the ZIF IC from pin 28 and is fed to the ASFIC audio signal filtering IC, which is part of the controller section of the radio.

In addition to the audio output signal, the receiver section provides a squelch signal output, which also is processed and used by the controller section of the radio to mute the receiver output during periods of no signal reception.

Transmitter Detailed Functional Description

The transmitter function of the radio is distributed between the controller, the synthesizer, and the transmitter power amplifier (PA) sections. This is shown on the overall functional block diagram for the radio, Figure 1. The portion of the transmitter function physically located in the controller section is described in the

Controller Section Theory of Operation

located in Volume 1 of this service manual. That portion includes the audio circuits that filter, amplify, and otherwise process the audio signal from the microphone and/or telephone handset. The portion of the transmitter function located in the synthesizer section of the radio is described in the

Synthesizer Detailed Functional Description

in this volume of the service manual. The synthesizer section of the transmitter receives the amplified and processed audio signal from the controller section and produces a frequency-modulated radio frequency carrier (injection) signal, which is input to the transmitter power amplifier (PA) section.

The remaining part of the transmitter function of the radio is located in the PA section. The following discussion covers the part of the transmitter function that is physically located in the PA section.

There are two different configurations of the PA section; one for the 12-Watt radio, and the other for the 30-Watt radio.

12-Watt Power Amplifier(Kits FLF5591A, B, C; FLF5604A, FLF5952A; HUF1190A)

The following discussion is based on the schematic diagram for the 12-Watt power amplifier (PA), on page 49 for kits FLF5591A, B, C, FLF5604A, and HUF1190A and on page 51 for kit FLF5952A.

The power amplifier (PA) is a radio frequency (rf) power amplifier, which amplifies the output from the injection string (TX_INJ) to an RF output power level of 12 Watts. It consists of a driver stage Q6501, followed by a power amplifier module U6501.

In kits FLF5591A, B, C and FLF5604A, the second and third stages of U6501 operate directly from the A+ supply voltage received from connector J6502 via current sense resistor R6520. To protect the input stage from voltage transients on the A+ line, the first stage of U6501 is operated from the keyed K9.1 voltage, which is provided by the controller section of the radio.

In kit FLF5952A, two DC supply inputs for U6501 (+DCISUP and +DCISUPP) are obtained directly from the A+ line via R6520. The transmit enable input (+DCBIAS) is obtained from the A+ line via R6520 and switch U6502, which is controlled by the keyed K9.1 voltage.

The rf drive, which is routed into transistor Q6501, is controlled from Q6506 via the PA control line. A rising control voltage on the PA control line causes a rising collector voltage on Q6501. This causes more power to be delivered into the next stage. Conversely, a decreasing control line voltage decreases the power delivered into the next stage. By controlling the drive power to U6501 and the following stages in the power amplifier lineup, automatic level control (ALC) is accomplished, which regulates the output power of the transmitter.


The output of U6501 goes to the antenna switch. The antenna switch is switched by the keyed 9.1 voltage. In the transmit mode, the keyed K9.1 voltage is high. In kits FLF5591A, B, C and FLF5604A, the high K9.1 voltage turns on diodes CR6502, CR6503, and CR7504. When CR6502 is turned on, it forms a low impedance to the RF transmit path and allows the signal to pass through. Diode CR6503 forms a low impedance that is transformed to an open circuit through a quarter wavelength transmission line. This prevents transmitter power from being delivered into the receiver. Diode CR7504 is also turned on in the transmit mode, further isolating the receiver port from transmitter energy. In the receive mode, all these diodes are off. The off capacitance of CR6502 is tuned by L6508 to form a high impedance looking into the transmitter. Therefore, energy coming in the receive mode is channeled to the RX port.

In kit FLF5952A, the antenna switch has only two diodes (CR6502 and CR6504). The two diodes are forward biased by the K9.1 voltage in transmit mode and zero biased in receive mode.

Harmonics of the transmitter are attenuated by the harmonic filter. In kits FLF5591A, B, C and FLF5604A, the harmonic filter is formed by two inductors (L6512 and L6513) and six capacitors (C6539, C6540, C6542, C6543, C6544, C6546). This network forms a low-pass filter to attenuate harmonic energy of the transmitter to an acceptable level. In kit FLF5952A, there are only three capacitors (C6543, C6544, and C6546).

A forward power detector follows the harmonic filter. This forward power detector is a microstrip printed circuit, which couples a small amount of the forward power going out of the radio to diode CR6506 where it is rectified. This rectified signal forms a voltage that is proportional to forward power out of the radio. A power control circuit in the controller section of the radio holds this voltage constant, which ensures the forward power out of the radio is held constant.

In the PA compartment, 50k thermistor R6519 senses the temperature in the area of the power module. The resultant signal is fed back to the power control circuit to protect the power amplifier against over-temperature conditions. Resistor R6520, in series with the A+ line supply, feeds voltage to the power module. The voltage across R6520 is sensed and the resultant two inputs are channeled to the power control circuit. The power control circuit senses the voltage drop across this resistor, which is determined by the magnitude of the drain current in U6501. It uses this as a limit mechanism whereby the power control circuit limits the magnitude of current that can be drawn by U6501. This protects the device from excessive power dissipation.

Reverse polarity protection for the transmitter is provided by diode CR6508. The cathode is soldered to the A+ line while the anode is shorted to the chassis via a spring. In kits FLF5604A and FLF5952A, the diode is a surface mount device and the anode is soldered to the printed circuit board ground plane.Under reverse polarity conditions to the radio, this diode conducts and protects the radio from damage. This diode also provides transient over-voltage protection by breaking down when the supply voltage to the radio exceeds 24 volts.


30-Watt Power Amplifier(Kits FLF5592A, B, C; FUF5752A; FLF5606A; HUF1191A)

The following discussion is based on the schematic diagram for the 30-Watt power amplifier (PA) on page 53 for kits FLF5592A, B, C, FUF5752A, and HUF1191A, and on page 55 for kit FLF5606A.

The power amplifier (PA) is a radio frequency (rf) power amplifier, which amplifies the output from the injection string (TX_INJ) to an RF output power level of 12 Watts. It consists of a driver stage Q6501, followed by a power amplifier module U6501.

In kits FLF5592A, B, C, FUF5752A, and HUF1191A, the second and third stages of U6501 operate directly from the A+ supply voltage received from connector J6502 via current sense resistor R6520. To protect the input stage from voltage transients on the A+ line, the first stage of U6501 is operated from the keyed K9.1 voltage, which is provided by the controller section of the radio.

In kit FLF5952A, two DC supply inputs for U6501 (+DCISUP and +DCISUPP) are obtained directly from the A+ line via R6520. The transmit enable input (+DCBIAS) is obtained from the A+ line via R6520 and switch U6502, which is controlled by the keyed K9.1 voltage.

The rf drive, which is routed into transistor Q6501, is controlled from Q6506 via the PA control line. A rising control voltage on the PA control line causes a rising collector voltage on Q6501. This causes more power to be delivered into the next stage. Conversely, a decreasing control line voltage decreases the power delivered into the next stage. By controlling the drive power to U6501 and the following stages in the power amplifier lineup, automatic level control (ALC) is accomplished, which regulates the output power of the transmitter.

The output of U6501 goes to an additional power amplifier stage (Q6505) whose output is coupled to the antenna switch via a matching hybrid (H6501). Transistor Q6505 raises the 12-Watt RF power output level of U6501 to the required 30 Watts. Matching hybrid H6501 ensures the proper collector load for Q6505 and provides correct impedance matching between the output of Q6505 and the antenna switch.

The antenna switch is switched by the keyed 9.1 voltage. In the transmit mode, this keyed 9.1 voltage is high turning on diodes CR6502, CR6503, and CR1. When CR6502 is turned on, it forms a low impedance to the RF transmit path and allows the signal to pass through. Diode CR1 forms a low impedance that is transformed up to an open circuit through a quarter wavelength transmission line. This prevents transmitter power from being delivered into the receiver. Diode CR6503 is also turned on in the transmit mode further isolating the receiver port from transmitter energy.

In the receive mode all the diodes are off. The off capacitance of CR6502 is tuned by L6508 to form a high impedance looking into the transmitter. Therefore, energy coming in the receive mode is channeled to the RX port. Harmonics of the transmitter are attenuated by the harmonic filter. The harmonic filter is formed by components L2, L3, and L4, and capacitors C3, C5, C7, and C9. This network forms a low-pass filter to attenuate harmonic energy of the transmitter to an acceptable level.


A forward power detector follows the harmonic filter. This forward power detector is a microstrip printed circuit, which couples a small amount of the forward power going out of the radio to diode CR2 where it is rectified. This rectified signal forms a voltage that is proportional to forward power out of the radio. A power control circuit in the controller section of the radio holds this voltage constant, which ensures the forward power out of the radio is held constant.

In the PA compartment, 50k thermistor R6519 senses the temperature in the area of the power module. The resultant signal is fed back to the power control circuit, in the controller section of the radio, which protects U6501 by reducing the power output in the event of an over-temperature condition. Resistor R6520, in series with the A+ line supply, feeds voltage to the power transistor. The voltage across R6520 is sensed and the resultant two inputs are channeled to the power control circuit. The power control circuit senses the voltage drop across this resistor, which is determined by the magnitude of the drain current in Q6505. It uses this as a limit mechanism whereby the power control circuit limits the magnitude of current that can be drawn by Q6505. This protects the device from excessive power dissipation.

Reverse polarity protection for the transmitter is provided by diode CR6508. The cathode is soldered to the A+ line while the anode is shorted to the chassis via a spring. In kits FLF5606A and FUF5752A, the diode is a surface mount device and the anode is soldered to the printed circuit board ground plane.Under reverse polarity conditions to the radio, this diode conducts and protects the radio from damage. This diode also provides transient over-voltage protection by breaking down when the supply voltage to the radio exceeds 24 volts.

Synthesizer Detailed Functional Description(All Kits)

The synthesizer section of the radio generates the first conversion local oscillator signal and the second conversion reference oscillator for the receiver portion of the radio. It also generates the transmitter rf carrier signal, which is frequency modulated by the amplified and processed audio signal from the output of the audio signal filter IC (ASFIC) in the controller section of the radio. The frequency modulated transmitter rf carrier signal is amplified by the transmitter PA section of the radio.

The following discussion is based on the schematic diagram for the synthesizer section on page 57. The synthesizer section consists of a pendulum reference oscillator (U6704) and a phase locked loop (PLL), which is made up of a fractional-N synthesizer integrated circuit (IC), (U6702), a loop filter, two voltage controlled oscillators (VCO) (U6711 and U6712), a buffer amplifier (U6703), and a feedback amplifier (Q6710).

The pendulum reference oscillator (U6704) contains a temperature compensated crystal, which has an oscillation frequency of 16.8 MHz. The output of the oscillator (pin 10 of U6704) is applied to pin 14 (XTAL1) of U6702 via C6717 and R6701. VCOs U6711 and U6712 are varactor tuned. The VCO frequencies are controlled by the voltage applied to pin 10 of U6711 and U6712. This control voltage ranges from about 2.5 to10.5Vdc. A small control voltage produces a lower frequency and a large control voltage produces a high frequency, respectively.


The RX VCO U6712 (861 - 867 MHz frequency range) provides the first LO injection frequency for the receiver, which is 73.35 MHz below the carrier frequency. The RX VCO is selected by setting pin 7 high on U6712.

The TX VCO U6711 (896 - 941 MHz frequency range) provides the transmit frequency in conventional mode and the transmit frequencies in talk around mode. The Tx VCO is selected by setting pin 8 high on U6711.

The buffer stage (U6703) and the feedback amplifier (Q6710) provide the necessary gain and isolation for the phase locked loop.

The fractional-N synthesizer IC, U6702, consists of a prescaler, a programmable loop divider, control divider logic, a phase detector, a charge pump, an A/D converter for low frequency digital modulation, a balance attenuator to balance the high and low frequency analog modulation, a 13V positive voltage multiplier, a serial interface for control, and a super filter for the regulated 9.3 volts. Q6709 is used as a current amplifier for the super filter. The output voltage of the super filter (collector of Q6709) drops from 9.3V to about 8.5V. This filtered 8.5Vdc supplies the voltage for the VCOs (U6711 and U6712), the TX/RX VCO switches (U6708 and U6710), the feedback amplifier (Q6710), and the synthesizer charge pump resistor network (R6705, R6706 and R6755).

The synthesizer supply voltage is provided by the 5V regulator (U6705). The 2.1 MHz reference signal (pin 10 of U6702) is generated by dividing down the signal of the reference oscillator U6704 after it is applied to pin 14 of U6702.

In order to generate a high voltage that supplies the charge pump output stage at pin VCP (pin 36 of U6702), 13 V is generated at pin 1 of CR6701 by the positive voltage multiplier circuitry (CR6701). This voltage multiplier is basically a diode capacitor network driven by two 1.05 Mhz, 180 degrees out of phase signals (pins 8 and 9 of U6702).

The serial interface (SRL) is connected to the controller section of the radio via the data line (pin 2 of U6702), clock line (pin 3 of U6702), and chip enable line (pin 4 of U6702). Proper enabling of these lines allows the controller section to load the fractional-N synthesizer IC.

The output of the VCO (pin 4 of U6712 or pin 6 of U6711) is fed into the buffer input port (pin 1) of U6703 through an attenuator network (R6707, R6708, R6709). The output of the buffer, pin 5 of U6703, is applied to the input of the feedback amplifier (Q6710) through an attenuator network (R6749, R6750, R6751). To close the synthesizer loop, the output of Q6710 is connected to the PREIN port (pin 21) of synthesizer U6702. The buffer output (pin 5 of U6703) also provides signal for the receiver LO injection and the transmit injection string circuit. The charge pump current is present at pin 31 of U6702.

The loop filter (which consists of R6702, R6703, R6704, C6732, C6734, C6735, C6736, C6737, C6785, C6786, C6817, C6818) transforms this current into a voltage. That voltage is applied to pin 8 of the TX VCO (U6711) or pins 7 of RX VCO (U6712), which alters the output frequency.


The phase locked loop is frequency modulated by the transmit audio signal from the controller section. To accomplish this, the audio signal from the controller section is applied to pin 5 of fractional-N synthesizer IC U6702.

An A/D converter in the fractional-N synthesizer IC converts the analog modulating signal into a digital code, which is applied to a loop divider. This causes the carrier frequency to deviate. A balanced attenuator is used to adjust the VCO’s deviation sensitivity to high frequency modulating signals. The output of the balanced attenuator is present at the MOD OUT port (pin 30 of U6702).

The transmit injection string in the synthesizer consists of two amplifier stages (Q6702 and Q6704) whose main purpose is to maintain a constant output to drive the RF power amplifier and to provide isolation. The two stages (Q6704 and Q6702) are actively biased through Q6701 and Q6703. The TX injection string is on only during the transmit mode with K 9.1V.

This section provides a replacement procedure for Q6505, the rf power output transistor in the 30-Watt power amplifier.

Replacement of Transistor Q6505

To replace Q6505, proceed as follows:

Disassembly of Radio

1. Remove transceiver board from radio chassis following procedure provided in Volume 1 of this service manual, Motorola Publication 68P81083C20.

2. After transceiver board is removed from radio chassis, clean off thermal paste from all surfaces that have thermal paste on them using low lint wipers or rag.


Removing Faulty Transistor

1. Before removing faulty transistor, observe carefully how flange capacitors C6567 and C6568 are mounted. This will help you later in mounting new capacitors.

2. Set hot air gun for medium temperature and low air speed. This will ensure that other components in vicinity of Q6505 will not get dislodged and moved accidently.

3. Train hot air gun on flanges of transistor. After a few moments, the solder holding flanges will reflow enabling transistor and flange capacitors C6567 and C6568 to be lifted off transceiver board together.

Preparing Transceiver Board for New Transistor

1. Using solder wick, isopropyl alcohol, and stiff bristle brush, remove excess solder and clean pads on transceiver board where transistor was soldered.

2. Place transceiver board, with its heavy side up, on transistor assembly tool. Heavy side is side with DC-power and antenna connectors. Make certain that all four guide pins on transistor assembly tool are engaged into their corresponding holes in transceiver board.

3. Identify the six pads on transceiver board corresponding to the six flanges on transistor. The four corner pads are ground; the middle pad towards antenna connector is the transistor collector; and the opposite middle pad is the transistor emitter.

NOTE:

In next step, be certain to tin transistor pads and fill via holes with high temperature solder, composition SN96PB04.

4. Using solder iron, carefully tin each of the six pads so that they are covered with a thin coat of solder and all via holes are filled.

Positioning New Transistor

1. Place a small spot of flux on each of the six transceiver-board pads to which the flanges of transistor are to be soldered.

2. Insert the narrow-diameter side of a spacer, Motorola Part Number 4380545K01, into each of the two transistor mounting holes in transceiver board.

3. Ensure that new transistor is correct replacement type by verifying that M25C20 is printed on transistor face.

NOTE:

Collector flange of transistor is the one with its corner cut off.

4. Position new transistor onto transceiver board with collector flange oriented towards antenna connector. Ensure that transistor is sitting snug on transceiver board with all six flanges flat on their corresponding transceiver-board pads.

5. Lower arm of Distaco clamp on transistor assembly tool. Then lock clamp with its lever to clamp transistor in place on transceiver board.


Soldering Transistor

1. Place a small spot of flux on each of the six transistor flanges.

2. Solder each transistor flange to transceiver board as follows:

1. - Set soldering iron temperature to approximately 400 degrees Centigrade.

2. - Melt a small mound of solder onto flat face of soldering iron.

3. Press face of soldering iron firmly to flange for

no more

than three to four seconds.

4. Inspect transistor flange carefully to ensure it is soldered securely, and that it is not shorted to any of the other flanges or to the transistor heat sink.

Installing Flange Capacitors C6567 and C6568.

NOTE:

Capacitors C6567 and C6568 get mounted flat on transistor collector and ground flanges with non-sol-derable edge flush against transistor body. Each capacitor is attached by soldering its outside solderable edge to one of the transistor ground flanges and its inside solderable edge to transistor collector flange. There must be a gap of approximately 2 milli-meters between the two capacitors (i.e., room to insert a chisel style solder iron tip) to ensure that good solder joints can be made between capacitor leads and collector flange of transistor.

1. Ensure that both capacitors C6567 and C6568 are correct replacement type by verifying that Motorola Part Number is 2113742B23, value is 12pF, and marking is C1.

2. Solder outside solderable edge of each capacitor to one transistor ground flange, being certain that each capacitor is flat on transistor flange with non-solderable edge flush against transistor body.

In next step, to avoid damage to transistor and capacitors, ensure that each soldering operation takes no more than three to four seconds to accomplish.

!C a u t i o n

!C a u t i o n

In next two steps, to avoid damage to transistor and capacitors, ensure that soldering operations take no more than three to four seconds to accomplish.


3. Place a small drop of flux on transistor collector flange between capacitors. Place chisel style solder iron tip between capacitors and onto collector flange of transistor. Feed in some high temperature solder (SN96PB04) so that inside solderable edges of both capacitors are soldered securely to collector flange of transistor.

4. Examine soldered capacitors. Ensure that they are reasonably flush against transistor body and are not shorting transistor collector flange to transistor heat sink.

5. Examine surrounding components to ensure that none of them have been damaged or displaced.

Reassembly of Radio

1. Examine face of transistor heat sink. Ensure that it is free from burrs and flux, which could prevent a good thermal contact to radio chassis.

2. Spread thermal compound on heat sink of the following components:

•

Transistor Q6505

•

PA module U6501

•

Audio PA module U0203

•

+5V regulator U0500
