Filters and multiplexers for the INTELSAT VII payload

The filtering and multiplexing requirements for this new generation of INTELSAT spacecraft have been especially demanding. Particularly for the Ku-band output multiplexer, the large number of channels to be multiplexed over the full 10.9-12.8 GHz band has meant that some challenging design problems had to be overcome before breadboard models could be successfully built and tested. The author describes C-band input multiplexers, Ku-band output multiplexers, and C-band output multiplexers
