| Abstract(in English) | A buried p^+-AlGaAs gate AlGaAs / InGaAs / AlGaAs double heterojunction FET has been developed for power amplifiers of advanced wireless communication handsets. The buried p^+-AlGaAs gate was formed by Zn diffusion technique. A low on-resistance of 1.6Ωmm and a high gate built-in voltage of 1.5V with a maximum transcondutance of 420mS / mm were realized for a 0.8μm gate device. An output power of 22.1dBm, an ACPR of -48.8dBc / 30KHz and an efficiency of 50.4% were obtained under 1.9GHz narrow band CDMA signal excitation and positive gate bias operation. |
