A Preliminary Design of Ka-band On-Board Switching Transponder for COMS

SATellite COMmunication (SATCOM) System is to be applied in the Communication, Oceanographic, and Meteorological Satellite (COMS). ETRI has completed the preliminary design effort for the SATCOM project - an effort which included clarifying requirements, refining mission description and operation, determining the configuration of the payload, and anticipating subsystem performances, schedules, costs, and so on. This paper includes an overview of the project work, and the preliminary design of the Ka-band on-board switching transponder in point of RF performances. A recommendation for future work is also included to aid subsequent projects associated with SATCOM system.
