20 GHz GaAs FET Amplifier for H-SAT Repeater

This paper describes the results of a study undertaken for the European Space Agency to evaluate currently available GaAs MESFETs, and the development of an amplifier suitable for inclusion in a proposed 20/12 GHz H-SAT repeater. The study was undertaken during the period January 1979 to May 1980 prior to the WARC-77 Conference, which subsequently al1ocated a frequency of 17.3 GHz. However, the study indicated the performance capability of the available short gate length MESFETs (0.6¿m).
