How the transceiver works
C-Band Transceiver 5700 series Reference Manual

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.
Depending upon the isolation provided by the OMT, a TRF may not be necessary on
some antennas.
Power supply unit
The Power Supply Unit 5582B is a robust, wide-range power supply. It is specifically
designed to provide the nominal 48 V DC supply required by the C-Band transceiver.
The supply source is 50/60 Hz, 115/230 V AC mains.
The PSU is unregulated and behaves like a simple transformer/rectifier supply. The DC
voltage output to the transceiver will be somewhere between 37 V (at very low mains)
and 72 V (at high mains).
The positive output of the PSU is earthed for protection. An auxiliary 48 V DC output is
provided for powering a redundancy system.
