SUPERCONDUCTING CUEING RECEIVER FOR SPACE EXPERIMENT

Exploiting the high-temperature superconductor YBa2Cu3O7-x, (YBCO), we have extended chirp-transform processing to instantaneously analyze t he spectrum of an incoming signal over greater bandwidth than any comp eting technology. A compact receiver has been developed that will anal yze a 3-GHz-bandwidth in 120 ns with 110-MHz resolution. The cryogenic YBCO chirp filter and ambient-temperature semiconductor electronics h ave been space qualified for flight on the Navy's High-Temperature Sup erconductivity Space Experiment, a package to be launched on the Air F orce ARGOS scientific satellite.
