Abstract
The authors describe the 950MHz power performance of a 2.2V operation double-doped AlGaAs/InGaAs/AlGaAs heterojunction FET(HJFET) for person al digital cellular telephones. The fabricated HJFET exhibited 600mA/m m maximum drain current, 260mS/mm transconductance and 9.4V gate-to-dr ain breakdown voltage. A 21mm gate-periphery device operating with a d rain bias of 2.2V, demonstrated 1.86W (32.7dBm) output power and 62.8% power-added efficiency with -50.5dBc adjacent channel leakage power a t 50kHz off-centre frequency.
