Abstract: 4H-SiC MESFETs are fabricated on semi-insulating SiC substrates.Key processes are optimized to obtain better device performance.A microwave power amplifier is demonstrated from a 1mm SiC MESFET for S band operation.When operated at a drain voltage of 64V,the amplifier shows an output power of 4.09W,a gain of 9.3dB,and a power added efficiency of 31.3%.

Key words: 4H-SiC, MESFET, microwave, power amplifier
