The gain, noise figure, and 1‐dB compression point of a commercially available GaAs amplifier were measured at cryogenic temperatures. The gain and noise figure characteristics were improved by decreasing temperature, while the 1‐dB compression point remained unchanged. Repeated temperature cycling had no adverse effect on amplifier performance. © 1992 John Wiley & Sons, Inc.
