This study investigates the performance in output power and efficiency enhancements of Reversed Doherty Power Amplifiers (RDPA) compared to Conventional Doherty Power Amplifiers (CDPA) under varying Quarter-Wave Transformer Losses (QWTL) from 1 dB to 5 dB. The RDPA achieves a comparable maximum output power (Psat) of 47.55 dBm, with a 6 dB back-off point showing consistent performance superiority, maintaining a lead of 0.7–2.9 dB across QWTL conditions. Despite a 1.25 dB decrease in saturation power due to QWTL, RDPA demonstrates a notable improvement in Power Added Efficiency (PAE), achieving 43% at 6 dB back-off, compared to CDPA’s 35%. Efficiency at other load conditions (OBO) for RDPA also consistently outperforms CDPA, with PAE ranging from 3.79% to 25.83% depending on QWTL and Drain efficiencies (DE) of the carrier and peaking amplifiers. These results highlight the RDPA’s resilience to QWT losses and its potential for energy-efficient wireless applications, positioning it as a strong candidate for next-generation high-efficiency amplifier designs.
