,The Superconductor Insulator Superconductor Mixer Receiver — A Review,onductor (SIS) tunnel junction when subjected to microwave radiation at 38 GHz. This step structure was later explained by Tien and Gordon. in terms of the photon assisted tunneling of single electrons across the tunnel barrier. Several years later, Tucker developed a full quantum mechanical treatme

,A 75–110 GHz Sis Mixer With Integrated Tuning and Coupled Gain,nstructed and tested. The design is a demonstration of a prototype receiver element in a focal plane array receiver. The large instantaneous bandwidth was accomplished with a broadband waveguide-to-microstrip transition and a scale-modeled microstripline circuitry. The transition to microstripline c

Low Noise Dc Squids for the 1990S, quantum limit, significant advances in integrated SQUID detectors, and a shift from Pb-alloy to all-refractory technology. The discovery of high-T. superconductivity in 1986 was soon followed by the demonstration of high-T. SQUIDs, with bulk and thin-film versions now operating at or above 77K. The
