Abstract: AlGaN/GaN high electron mobility transistors grown on sapphire substrates with a 0.3μm gate length and 100μm gate width are fabricated.The device reveals a drain current saturation density of 0.85A/mm at a gate voltage of 0V and a peak transconductance of 225mS/mm.The unity current gain cutoff frequency and maximum frequency of oscillation are obtained as 45 and 100GHz,respectively.The output power density and gain are 1.8W/mm and 9.5dB at 4GHz,and 1.12W/mm and 11.5dB at 8GHz.

Key words: AlGaN/GaNHEMTsapphire
