This paper describes cryogenic broad-band amplifiers with very low power consumption and very low noise for the 4–8-GHz frequency range. At room temperature, the two-stage InP-based amplifier has a gain of 27 dB and a noise temperature of 31 K with a power consumption of 14.4 mW per stage, including bias circuitry. When cooled to 15 K, an input noise(More)
This paper describes cryogenic broadband amplifier with very low noise for the frequency band 1.5-4.5 GHz. At 15 K the twostage 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(More)
