Miniature Spaceborne S and K/sub u/-Band Low Noise Amplifiers for TDRSS

Light weight, miniature spaceborne parametric and transistor low noise amplifiers (LNA´s) have been developed for TRW and Western Union for use in NASA´s Tracking and Data Relay Satellite System (TDRSS). The S and Ku-Band LNA´s each employ a single stage parametric amplifier and provide state-of-the-art noise temperatures of less than 65K and 140K over their respective 2.2-2.3 GHz and 14.89-15.12 GHz frequency ranges.
