A C-BAND SUPERCONDUCTIVE INPUT MULTIPLEXER FOR COMMUNICATION SATELLITES

The paper demonstrates the feasibility of building a fully integrated C-band ii-channel superconductive multiplexer employing 8-pole hybrid dielectric/HTS thin film filters. Experimental results are presented f or 4-pole and 8-pole externally-equalized superconductive fitters havi ng 1% bandwidth. The measured data for the integrated multiplexer clea rly indicates that C-band superconductive multiplexers are approaching the performance requirements of typical satellite systems and have th e potential of large reduction in mass and volume over conventional te chnologies. The critical design considerations of such type of superco nductive multiplexers are discussed.
