摘要

We report a 5 GHz linear InGaP/GaAs HBT monolithic microwave integrated circuit (MMIC) power amplifier for wireless LAN applications. The three-stage power amplifier operates with 103 rnA - low quiescent current of Class AB mode using active bias circuit under a single supply of +3.3 V. A total current of 196 (194)mA is consumed with an output power of 18dBra and PAE (power-added efficiency) of 9.7% at 5.25(5.15)GHz. The power amplifier exhibits a power gain of 19.6 (17.8/18.5)b, 1-b compression point (P] b) of 26 (25/25) dAm, and PAE of 27.8 (25.4/20)% at 5.25 (5.15/5.85)GHz. Measured third-order IMD (intermodulation distortion) is less than -25 dBc at 3 b back-off and less than -30 dBc at 5 b back-off from Pi b for the frequency range between 5.15 and 5.85 GHz.
