High-efficiency performance of microwave power 4H-SiC amplifiers

The high frequency performance of a 4H-SiC MESFET is examined using an advanced harmonic-balance device/circuit simulator combined with the two-dimensional device simulator PISCES-IIB. Very good agreement with experimental measurements is achieved. Circuit and device optimizations are discussed. An improved device structure with a maximum power added efficiency approaching the theoretical limit is predicted.
