Abstract :
Quarter-micron gate length high electron mobility transistors have been fabricated using an electron-beam direct-writing technique. A maximum stable gain of 10 dB at 18 GHz has been measured at room temperature. A room-temperature cutoff frequency fT as high as 45 GHz has also been obtained.
