摘要
A 3.3V operation single InGaP/GaAs HBT power amplifier MMIC (Monolithic Microwave Integrated Circuit) was developed for 2.4GHz/5GHz dual-band WLAN (Wireless Local Area Network) applications. The fabricated MMIC was as small as 1,070x1,000 mum(2) including input matching circuit, interstage matching circuit, and bias circuit with band selection function. The highly linear and efficient amplifier exhibits a PIdB (1dB gain compression output power) of 27 (27.2/27)dBm with a PAE (Power Added Efficiency) of 42 (31.2/31)% at 2.45 (5.2/5.3)GHz. The linear output power for the EVM (Error Vector Magnitude) of 5% using a 54Mbps 64 QAM (Quadrature Amplitude Modulation) OFDM (Orthogonal Frequency Division Multiplexing) signal was 22 (21.2/21)dBm with the PAE of 23.5 (16.5/16.5)% at 2.45 (5.2/5.3)GHz.
