Abstract
A cryogenic single-stage broadband f.e.t. amplifier with an average noise temperature of 34 K (0.5 dB) over a bandwidth of 2 GHz has been developed. The average gain is 12 dB. The best spot noise temperature is 17 K (0.25 dB) at 3.2 GHz, which is competitive with cryogenic parametric amplifiers.
