We are developing a low-noise and low-power microwave amplifier, etc. using the frequency conversion gain of superconductor-insulator-superconductor (SIS) mixers. Those microwave circuits consist of one frequency up-converter and one frequency down-converter connected in series. We have so far successfully demonstrated the principle of low-noise amplification operation, etc. using waveguide components. We now report on our study of a design method for microwave circuits consisting of two SIS mixers.
