We are developing a low-noise, low-power microwave amplifier that utilizes the frequency conversion gain of SIS mixers. Aiming at chip-level integration using SIS up/down converters and a Josephson oscillator, we have previously demonstrated amplification principles and oscillators using waveguide modules. In this study, we designed and fabricated a prototype chip integrating two SIS mixers and a Josephson oscillator.
