What is 47GHz 4-Way Doherty PA Design Insights about?

This document presents a 4-way Doherty power amplifier (PA) designed for the 47GHz 5G band, achieving notable performance metrics including 23.7dBm P1dB and 26.8% peak power-added efficiency (PAE). The design incorporates adaptive biasing and a new Doherty network synthesis flow, which reduces complexity by using fewer transformers while maintaining efficiency. The prototype demonstrates significant improvements in efficiency and modulation capabilities for wideband 5G NR signals, outperforming existing mul
