Abstract
A GaAs power MESFET has been optimized for Ka-Band operation. The device has an n/sup +/ ledge channel structure with a 0.25- mu m gate on MBE-grown material. An output power density of 0.71 W/mm was achieved with 5.2-dB gain and 34% power-added efficiency. When tuned for maximum efficiency, a power-added efficiency of 41% was obtained with a power density of 0.61 W/mm and a gain of 5.6 dB.Keywords
