Abstract
A 4.5 to 5.0 GHz gallium arsenide field-effect transistor (GaAs FET) amplifier cryogenically cooled to 20 K is described. A noise figure of 1.1 dB maximum is achieved over the band. Gain per stage is approximately 10 dB. A noise analysis is performed to predict noise figure dependence on the physical temperature of the amplifier.
