Maintainability and reliability are required to sustainably operate a satellite communication system. This chapter presents highly maintainable and reliable radio frequency (RF) transceiver structures for satellite base stations. We have developed two types of RF transceivers: one with a C-band gallium nitride (GaN) solid-state power amplifier (SSPA) and one with an output control manager of two Ku-band traveling wave tube amplifiers (TWTAs). We show the structures and evaluate the performances of the RF transceivers.
