## Abstract We propose a linearity‐enhanced Doherty power amplifier using an analog predistortion (APD) technique, which incorporates an intermodulation (IM) generator.Because the IM generator is configured with antiparalleled diode structure, the resulting Doherty power amplifier behaves different

## Abstract In this article, a 3.7 GHz band Doherty amplifier based on GaN HEMTs, which is linearized using a digital predistortion method, is implemented for 4th generation wireless communication systems. The forward and reverse models of the Doherty amplifier for the predistortion consist of simp

## Abstract In this article, we propose the wideband digital predistortion (WDPD) for a highly linear and efficient GaN HEMT Doherty power amplifier (DPA). The WDPD is composed of the memory less DPD and the memory system, which compensates for the memory effects to achieve a highly linear wideband
