2.4 GHz GaAs PHEMT medium power amplifier for wireless LAN applications

This paper describes the design and measurement of a medium power amplifier (MPA) using 0.15µm GaAs PHEMT technology for wireless application. At 2.4 GHz and 3.0 V of V
DS
, a fabricated MPA exhibits a P1dB of 15.20 dBm, PAE of 12.70% and gain of 9.70 dB. The maximum current, Imax is 84.40mA and the power consumption for this device is 253.20mW. The die size of this amplifier is 1.2mm × 0.7mm.
