摘要

我们提出了一种毫米波三向Doherty输出网络合成方法，该方法可以在吸收器件寄生电容的同时实现接近理想的双峰Doherty有源负载调制。根据这种方法，我们提出了一个38GHz的PA原型，在9.5dB / 11.5dB的回退下实现了13.7% / 11.0%的PAE，这是在30GHz及以上工作的硅PA中最高的。在n260频段的1-CC和2-CC 5G NR FR2 64-QAM OFDM信号下进行测试，PA显示出最先进的平均输出功率(11.3dBm)和平均效率(14.7%)。

A 38GHz Deep Back-Off Efficiency Enhancement PA with Three-Way Doherty Network Synthesis Achieving 11.3dBm Average Output Power and 14.7% Average Efficiency for 5G NR OFDM

We propose a mmWave three-way Doherty output network synthesis methodology that can realize close-to-ideal dual-peaking Doherty active load modulation while absorbing the device parasitic capacitance. Following this methodology, we present a 38GHz PA prototype, achieving 13.7% / 11.0% PAE at 9.5dB / 11.5dB back-off, which are the highest among reported silicon PAs operating at 30GHz and above. Tested under 1-CC and 2-CC 5G NR FR2 64-QAM OFDM signals in the Band n260, the PA demonstrates state-of-the-art average output power (11.3dBm) and average efficiency (14.7%).
