摘要：

The power performance of GaAs MOSFETs using Ga2O3(Gd2O3) as the gale dielectric is presented. The I-V characteristics of the power devices are virtually free of hysteresis, indicating low interface state density in the oxide/GaAs interface. When operated at 850MHz cellular frequency and tuned for maximum output power, maximum power-added efficiencies of 45 and 56% were obtained under 3 and 5V operation, respectively. An output power of 26.5dBm was measured from a 1 mu m x 2.4mm device under 5V operation. These results show that the developed GaAs MOSFETs are promising candidates for microwave power amplifiers.
