A Wideband linear CMOS power amplifier design for 2.3-GHz and 2.6-GHz m-WiMAX system

摘要：

In this work, a fully-integrated linear CMOS power amplifier (PA) is implemented in a 0.18-fim 1P6M RF CMOS process for 2-3-GHz and 2.6-GHz m-WiMAX system application. A wideband twisted figure-8-sbaped transformer is utilized as both the power combining and matching, which is operated across 1 GHz bandwidth. The PA operates at Class AB mode and can deliver 29.1 dBm with a 26.5*/* PAE at 1-dB compression point and offer 22 dB gain. EVM is lower than 5V. at 19 dBm average power under the 16 QAM mWiMAX modulation signal test. Digital feedback predistortion (DFDPD) technique is employed to improve spectrum linearity by 7 dB at 19 dBm average power level.
