Josephson Junctions as Heterodyne Detectors,

Abstract

Heterodyne detection with a point contact Josephson junction was investigated both experimentally and theoretically. The measured performance of the device at 36 GHz is in good agreement with the theory. By operating vanadium point contacts at 1.4K, the authors have achieved a single side band mixer noise temperature of 54K with a conversion gain of 1.35 and a signal bandwidth of the order of 1GHz. From the results one can extrapolate a potentially impressive performance for these devices at submillimeter wavelengths. (Modified author abstract)
