Abstract : The report covers research into superconducting receiver techniques concerned principally with the development of superconducting microwave mixers utilizing the Josephson effect and superconducting, ultra-high Q, microwave resonators, filters, and preselectors. The theory of operation of Josephson mixers, characterization into a mathematical model suitable for analytical and computer study, and a rigorous formulation of the DC I-V characteristics has been obtained. Experimental observation of the Josephson mixing action has been observed which is in excellent agreement with the theory developed. Superconducting, miniature microstrip resonators were built and the results of experimental determination of their Q's is reported. (Author)
