We have developed a test setup to measure frequency up-conversion gain in superconductor–insulator–superconductor (SIS) junctions at W band (75–110 GHz). A conventional SIS mixer with Nb/AlOx/Nb tunnel junctions was used as a frequency up-conve

In this paper, we present an investigation of the contribution of quantum susceptance in capacitance measurements of superconductor–insulator–superconductor tunnel junctions. We directly measured the one-port S -parameter S 11 by utilizing a 4-K

We are investigating a possible microwave amplifier with low noise and low power consumption at cryogenic temperature for large scale multi-pixel heterodyne superconductor-insulator-superconductor (SIS) receivers at millimeter and submillimeter wavel
