Abstract
A protection circuit is developed which protects transistors in the output stage of a High Power Amplifier against voltage breakdown as a result of mismatch. The circuit is applied in an S-band and X-band High Power Amplifier and measured under various mismatch conditions. The devices have been developed in the 6-inch 0.5 um GaAs power pHEMT process (PP50-11) of WIN Semiconductors
