Abstract :
Millimeter-wave power performance achieved by ion-implanted InGaAs-GaAs MESFETs with a gate length of 0.25 mu m is described. When a device with a gate width of 150 mu m was measured at 22 GHz, an output power of 95 mW, a power-added efficiency of 33%, and an associated gain of 7.3 dB were observed. At an output power of 93 mW, a power-added efficiency of 25% and an associated gain of 4 dB were obtained at 44 GHz. When a device with a gate width of 200 mu m was measured at 60 GHz, an output power of 121 mW with 3-dB associated gain and 13% power-added efficiency were observed.<>
