## Abstract In this article, we propose a highly linear and efficient twoβstage GaN HEMT asymmetrical Doherty power amplifier (ADPA) for WCDMA applications. The firstβstage driving DPA not only improves the linearity as the predistortion circuit but also reduces the power consumption in the driving
