A C-band superconductive input multiplexer for communication satellites

The paper demonstrates the feasibility of building a fully integrated C-band 4-channel superconductive multiplexer employing 8-pole hybrid dielectric/HTS thin film filters. Experimental results are presented for 4-pole and 8-pole externally-equalized superconductive filters having 1% bandwidth. The measured data for the integrated multiplexer clearly indicates that C-band superconductive multiplexers are approaching the performance requirements of typical satellite systems and have the potential of large reduction in mass and volume over conventional technologies. The critical design considerations of such type of superconductive multiplexers are discussed.<
