Abstract :
Microwave fTmeasurements were made and compared to a model that confirmed lateral spreading as proposed by Wemple et al. to explain the increased breakdown voltage of GaAs power FET´s compared to bulk breakdown. The model provides a useful tool for device diagnosis as well as evaluation of the frequency limit fT.
