辐《NEC技报》1996年第5期报道，NEC公司开发了用于Ku波段卫星通信用的GaAs系异质结FET。这种HJFET放大器的总栅宽为25mm，器件栅长为0．5Pm，采用高可靠的WSi／AZ栅；放大器在12GHZ下，输出功率为158W，功率附加效率为36％，线性增益为9．6dB，为目前最高水平。Ku波段15W的单
NEC reported in 1996 fifth issue 5, NEC company has developed for the use of Ku-band satellite communications GaAs heterojunction FET. This HJFET amplifier has a total gate width of 25 mm and a device gate length of 0.5 Pm with a highly reliable WSi / AZ gate. The amplifier delivers 158 W at 12 GHz with an additional power efficiency of 36% and a linear gain of 9. 6dB, the highest level for the moment. Ku band single 15W
