Abstract:This paper describes cryogenic broadband amplifier with very low noise for the frequency band 1.5-4.5 GHz. At 15 K the two-stage InP-based amplifier has a gain of 28+/-2 dB dB and a noise temperature below 5 K. For a narrower band of 2-4 GHz at 15 K the measured gain is 30.0+/-0.8 dB and noise temperature is 1.5 K. The total DC power consumption of the amplifier is 6.8 mW.
