Abstract
The characteristics of parametric amplifiers, including effective input noise temperature, bandwidth, stability, and gain compression are discussed. Two specific amplifiers, a liquid nitrogen cooled
-band unit for a radio astronomy observatory, and a three-channel unit for a satellite vernier auto track systems are described, and the characteristics of these amplifiers are presented.
