Abstract :
High-performance internally-matched GaN HEMT with 0.3 mum gate length and 4times2.5 mm of the total gate width was successfully fabricated. The large signal RF characteristics of the internally-matched device were measured at 8 GHz. A maximum output power of 64.5 W, a gain of 7.2 dB and a peak power-added efficiency (PAE) of 40% was obtained, respectively.
