Description
It receives V-band uplink signals from the feed payload, Ku-band uplink signals from the phased array antenna and accompanying telemetry signals from the satellite platform. Processed by amplification, frequency conversion and filtering, the service signals are delivered to the Ku transmit phased array, satellite platform and Q-band feed transmit antenna.
