Abstract :
Excellent RF performance is reported for AlGaN HEMTs fabricated on electrically insulating SiC substrates. The transistors have an fmax≈42 GHz, and an fT≈15 GHz. At 10 GHz, 320 μm wide transistors had a total power of 900 mW with a gain of 6.5 dB, which corresponds to a power density of 2.8 W/mm
