Abstract(in English) | This paper describes excellent 1.0V operatiion power performance of a double doped AlGaAs/InGaAs/AlGaAs heterojunction FET(HJFET)for Personal Digital Cellular Phones. A low on-resistance of a power FET is key issue for a high output power and a high efficiency. The developed FET with a multilayer cap consisting of a highly Si-doped AlGaAs and narrow recessed structure exhibited an on-resistance of 1.3Ω・mm and a maximum drain current of 620mA/mm. A 28mm gate-periphery device operating with a drain bias voltage of 1.0V demonstrated an output power of 1.0W, an associated gain of 13.7dB and a power-added efficiency of 59% with an adjacent channel leakage power at 50kHz off-center frequency of -48dBc. |
