摘要

This article presents a series voltage-combining Doherty power amplifier (PA) achieving high output power ( $P_{\mathrm {out}}$ ) and high power-back-off (PBO) efficiency for 28-GHz fifth-generation (5G) applications. We introduce a new transformer-based series output combiner design method to achieve a true-Doherty load modulation that uses a compact footprint. The output stages of the main PA an...
