Abstract
This paper describes the design and performance of a cryogenically cooled low-noise FET amplifier operating in the 22-24-GHz range. The amplifier employs five cascaded single-ended gain stages and an integral bandpass filter. Noise temperatures in the 200 K range with an associated gain of 28 dB are typical for the nine cooled units built to date.
