C-Band & Ku-Band Transceiver Systems

Overview The C-Band Systems are labelled the 5700 series. The Ku-Band Systems are labelled the 5900 series.

Both C-Band & Ku-Band systems have four major components. Theses components are: Power Supply Converter Module Solid State Power Amplifier (SSPA) LNA (C-Band) or LNB (Ku-Band)

Power SupplyReceives AC power from the ship and converts it to 48 VDC to power the Converter& SSPA modules. The AC input is switch selectable for either 220 VAC or 110 VAC

Converter Module- The Converter Module performs multiple functions.1. It provides the interfaces between the below decks equipment (modem & DAC) and the SSPA.2. Power levels, attenuation levels, and frequencies are programmed in this module using either a

PC or hand held controller.3. It controls the SSPA functions and displays fault conditions.4. It performs the frequency up conversion from 70 MHz to either C-Band or Ku-Band and the

down conversion from C-Band or Ku-Band to 70 MHz

Solid State Power Amplifier (SSPA)The SSPA receives DC power and theTransmit input frequency (C-Band or Ku-Band) from theConverter module. Also, any fault conditions will be relayed

to the Converter where it will be displayed on the frontpanel window.

LNA & LNB Provides the C-Band (LNA) or Ku-Band (LNB) signal to theConverter module for down conversion to 70 MHz.

Serial Communications

Monitor & Control

The Converter module is configured in two different ways. They are:1. Remotely by connecting a PC running HyperTerminal and using the Seatel

Supplied cable.2. Directly connecting the PC to the Converter using the supplied Codan cable.

The Hyper Terminal setup communication parameters are:9600 baud, 8 data bits, 1 stop bit , no parity, no hardware control, no flowcontrol

The remote connection is established using the available connector (labeledRS232) on the interconnect cable at the back of the DAC. This cable is suppliedby Seatel

The direct connection is established using the supplied Codan cable that isnormally located with the Spare Parts Kit.

Transceiver Connections - Front Panel

For Both the C-Band & Ku-Band Systems the Converter

Modules have the same Front Panel Connections. These

connections include:

RX IF Output (70 MHz signal to modem)

TX IF Input (70 MHz signal from modem)

Monitor & Control Connector

DC Power Input from Codan Power supply

SSPA DC voltage and control signals to amplifier

*C-Band Converter units have an LNA DC/Alarmconnector. The Ku-Band Converters do not.

TX RF Output - C-Band or Ku-Band signal sent to SSPA

RX RF Input Signal - LNA (C-Band or LNB Ku-Band)

SSPA DC voltage and control signals to amplifier

*Ku-Band Converters have a separate RX L-Band output.The C-Band Converters do not.

The RX L-Band Output is used mainly in combinedTransmit/Receive & TVRO systems. This is the full 500MHz receive band of the satellite

POWER OFF / STANDBY / ON switchWhen in STANDBY, only the reference oscillatorand M&C sections operate. The 5700 or 5900converter can be turned ON by the control-panelswitch, a serial data command or a remotecontact closure.

SSPA - INHIBIT / REMOTE / ACTIVATEThe Control Panel switch allows local activationor de-activation of the SSPA for maintenance,and for re-setting alarms. Remote control is alsopossible by serial data command or a dry-contactclosure

The highlighted switch positions correspond to:RS232 interface, ASCII protocol, 9600 bits/sec.,8data bits, no parity.

C-Band & Ku-Band Transceiver SystemsFrequency Conversions

For both the C-Band (5700) and Ku-Band (5900) Systems:

The Converter module accepts 70 MHz input from the SCPC modem (Transmit Path) which it

up converts to C-Band or Ku-Band frequencies and sends to the SSPA.

The Converter module receives the C-Band or Ku-Band input from the LNA or LNB and downconverts them to 70 MHz then sends them to the SCPC Modem.

The Local Oscillator (LO) for both C-Band and Ku-Band Converters is not a fixedfrequency. It can be adjusted, and is selected in consideration with the satellite RF band to becovered and the frequency range of the modem.

This means that the programmed frequency of the Converter is set to the Center Frequency ofthe specified satellite transponder. This Center Frequency, combined with the frequency rangeof the modem (+/- 18 MHz) allows the modem to be tuned to a specific frequency within each36 MHz satellite transponder.

The satellite transponder Center Frequency equals the SCPC modem Center Frequency of 70MHz.
