Design of linearity-enhanced and high-efficiency Doherty power amplifier using a new phase compensation technique

Ain Shams Engineering Journal
This paper introduces a methodology to design linearity-enhanced and high-efficiency Doherty power amplifier (DPA). The proposed approach leverages the phase difference within the DPA's combiner at the power combining point to regulate both amplitude-to ...
