摘要：
A new efficiency improvement technique is proposed for Doherty power amplifiers (PA), which combines supply switching with load modulation. The proposed technique was demonstrated with a commercial prototype GaN PA. Measurement and simulation results for the Doherty PA, using a 5MHz LTE signal, showed that the proposed technique significantly improved the average power-added efficiency (PAE) to similar to 55%.
