Feasibility Considerations for High Temperature Superconducting Transponders in Communication Satellites

This paper provides a comprehensive, background-rich framework around which a fully developed study of the use of superconducting transponders can be generated for a specific communication satellite. The approach divides results into two categories: signal benefits, and physical constraints. Each is realized in terms of metrics and methods warranted by the current state of superconductor technology. The paper describes methods by which signal performance of superconducting transponder components may be approximated; also methods of evaluating heat generated by such a system; and finally, the selection of an appropriate cryogenic cooling system.
