摘要

提出了一种新型的单端输出串联Doherty功率放大器(SDPA)，该放大器在输出匹配网络中省去了变压器。与传统的Doherty PAs相比，串联功率组合架构在缩放CMOS中提供更高的输出功率，并且适合微波和毫米波波段的集成。SDPA采用45纳米CMOS SOI实现，峰值输出功率为22 dbm，峰值和6db回退功率下的PAE分别为24%和20%。

A 14-GHz, 22-dBm Series Doherty Power Amplifier in 45-nm CMOS SOI

This paper presents a new series Doherty power amplifier (SDPA) with a single-ended output that eliminates transformers in the output matching network. The series power combining architecture offers higher output power in scaled CMOS compared to conventional Doherty PAs and is amenable to integration at microwave and millimeter wave bands. The SDPA is implemented in 45-nm CMOS SOI and achieves a peak output power of 22-dBm and PAE of 24% and 20% at peak and 6 dB back-off powers, respectively.
