  • Page 21: Band Transceiver Compliance

    C-Band transceiver compliance CODAN This chapter describes how to ensure the C-Band Transceiver 5700 series complies with the Radio and Telecommunications Terminal Equipment Directive 1999/5/EC. Only those transceivers fitted with the transmit frequency Band 2 option have been tested and certified for compliance with this Directive.

  • Page 22: Electromagnetic Compatibility And Safety Notices

    European EMC Directive, 89/336/EEC • European Low Voltage Directive, 73/23/EEC with no lower voltage limit Equipment supplied by Codan that satisfies these requirements is identified by the 0682 markings on the model label of the product. Some countries may restrict the use of satellite communications equipment on certain frequency bands or require such equipment to be licensed.

  • Page 23: Complying With The European Radio And Telecommunications Terminal Equipment

    Complying with the European Radio and Telecommunications Terminal Equipment Directive Electromagnetic compatibility To ensure compliance with the EMC Directive is maintained, you must: Use standard shielded cables supplied from Codan for all connections (see Table 6-1 on page 6-20 for the appropriate cables).
  • Page 24 C-Band transceiver compliance Use the standard DC supply cable shown to connect the DC power to the converter: PSU/SSPA Cable (Codan part number) 5582B 08-05634-xxx 5760/5712H 08-05961-xxx These cables have conductors with red insulation for the +ve supply connections, and conductors with black insulation for the –ve supply connections.
  • Page 25 EN 301 443 so that CE compliance with respect to radiated spurious signals is maintained. If necessary, consult Codan for more information. For CE compliance, the transceiver must be set up so that it does not enter the transmit on state upon power up.
  • Page 26 C-Band transceiver compliance To set up the transceiver for CE compliant operation you must: Enter the SPU1 command. Set the SSPA switch on the converter to REMOTE. Ensure the remote opto-isolated Req SSPA Activate input is either in the off state or left disconnected.

  • Page 62: Converter Module

    How the transceiver works Converter module The Converter Module 5700 provides the IF/RF frequency conversion functions required in a C-Band satellite earth station. It consists of an up converter and a down converter. Up converter The up converter converts the Tx IF input signals up to the appropriate Tx RF output via dual conversion.

  • Page 63: Synthesisers

    How the transceiver works Synthesisers The synthesisers contain two phase locked loops to produce the required SHF LO outputs. The resolution of the frequency control is 1 MHz. For a single synthesiser converter, the output of the synthesiser is actively split to produce the required Tx and Rx SHF LOs.

  • Page 64: Solid State Power Amplifier

    The SSPAs incorporate either a CPR137-G waveguide output or a N-type connector output (5705/5710/5720/5730/5740 only) and an integral heatsink. A cooling fan and shroud are fitted on all SSPAs except the 5705 SSPA. The fan operates whenever the SSPA is activated.

  • Page 65: Power Supply Unit

    How the transceiver works Transmit reject filter The TRF is a low-pass, waveguide filter. It has a low insertion loss in the specified receive pass band and high attenuation in the specified transmit reject band. The increased isolation between the receive and transmit ports provided by the TRF ensures that the transmit signals will not enter and overload the LNA or down converter.
