CIRCUIT DESCRIPTION

1. OverviewThis transceiver is UHF/FM portable transceiver designed

to operate in the frequency range of 470 to 520MHz (E2).

2. Circuit Configuration by FrequencyThe receiver is a double-conversion superheterodyne with

a first intermediate frequency (IF) of 44.85MHz and a secondIF of 455kHz. Incoming signals from the antenna are mixedwith the local signal from the PLL to produce the first IF of44.85MHz.

This is then mixed with the 44.395MHz second localoscillator output to produce the 455kHz second IF. This isdetected to give the demodulated signal.

The transmit signal frequency is generated by the PLL VCO,and modulated by the signal from the microphone. It is thenamplified and sent to the antenna.

5. Frequency Synthesizer Unit5-1. Frequency synthesizer

The frequency synthesizer consists of the VCXO (X1), VCO(A1), PLL IC(IC14) and buffer amplifiers.

The VCXO generates 16.8MHz. The frequency stability is1.5ppm within the temperature range of -30 to +60˚C. Thefrequency tuning and modulation of the VCXO are done toapply a voltage to pin 1 of the VCXO. The output of the VCXOis applied to pin 8 of the PLL IC.

The TK-380’s VCO consists of 2VCO and covers a dual rangeof the 425.15~475.15MHz (E2) and the 470~520MHz. The VCOgenerates 425.15~475.15MHz (E2) for providing to the first localsignal in receive. In TX, the pin 3 of the VCO goes low and theVCO generates 470~520MHz.

The output of the VCO is amplified by the buffer amplifier(Q16) and routed to the pin 5 of the PLL IC. Also the output ofthe VCO is amplified by the buffer amplifier (Q18) and routedto the next stage according to T/R switch (D9, D23).

The PLL IC consists of a prescaler, fractional divider,reference divider, phase comparator, charge pump. This PLLIC is fractional-N type synthesizer and performs in the 40, 50or 60kHz reference signal which is eighth of the channel step(5, 6.25 or 7.5kHz). The input signal from the pins 5 and 8 ofthe PLL IC is divided down to the 40, 50 or 60kHz and comparedat phase comparator. The pulsed output signal of the phasecomparator is applied to the charge pump and transformedinto DC signal in the loop filter (LPF). The DC signal is appliedto the pin 1 of the VCO and locked to keep the VCO frequencyconstant.

PLL data is output from DT (pin 75). CP (pin 19) and EP(pin 47) of the microprocessor (IC19). The data are input tothe PLL IC when the channel is changed or when transmissionis changed to reception and vice versa. A PLL lock condition isalways monitored by the pin 31 (UL) of the microprocessor.When the PLL is unlocked, the UL goes low.

Useful if ammeter equipped.

The following parts are required for adjustment

1. Antenna connector adapterThe antenna connector of this radio uses an SMA terminal.Use an antenna connector adapter [SMA(f) – BNC(f) or

SMA(f) – N(f)] for adjustment. (The adapter is not provided asan option, so buy a commercially-available one.)

NoteWhen the antenna connector adapter touches the knob,

draw out the knob to mount the connector.

2. Universal connectorUse the interface cable (KPG-36) for PC tuning or the lead

wire with plug (E30-3287-18) and screw (N08-0535-08) forpanel tuning. Connect the plug to the universal connector ofthe radio and tighten the screw.

The lead wire with plug (E30-3287-18) and screw (N08-0535-08) terminals are as follows. Numbers are universalconnector terminal numbers.

Caution1. When connecting the plug to the universal connector of

the radio, a short circuit may occur. To provent this, besure to turn the radio POWER switch off.

2. Since the RX AF output is a BTL output, there is a DCcomponent. Isolate this with a capacitor or transformer asshown in the figure.

3. Do not connect an instrument between red or black andGND.

Repair Jig (Chassis)Use jig (part No.: W05-0825-00) for repairing the TK-380.

Place the TX-RX unit on the jig and fit it with 7 screws.

The jig facilitates the voltage check and protects the modulewhen the voltage on the flow side of the TX-RX unit is checkedduring pepairs.

How to Remove the Flat Cable1. Gently draw out both sides of the connector lever uniformly

• Preparations for tuning the transceiverBefore attempting to tune the transceiver, connect the unit

to a suitable power supply.Whenever the transmitter is turned, the unit must be

connected to a suitable dummy load (i.e. power meter).The speaker output connector must be terminated with a

16Ω dummy load and connected to an AC voltmeter and anaudio distortion meter or a SINAD measurement meter at alltimes during tuning.

• Transceiver tuning(To place transceiver in tuning mode)Channel appears on LCD. Set channel according to tuning
