A Highly Efficient UHF Power Amplifier Using GaAs FETs for Space Applications

This paper discusses a highly efficient linear GaAs MESFET UHF power amplifier developed for application in an SSPA for a government space program. GaAs devices have not been used at UHF because of concerns over stability and their high cost relative to other available device technology. In space, efficiency is a primary concern and reliability can outweigh… CONTINUE READING
