摘要

本文介绍了76-81 GHz功率放大器(PA)在65纳米CMOS技术上的实现。定制的晶体管模型使设计电路工作在毫米波波段。为了减少占用空间和匹配损失，滤波器的输出匹配采用了低通网络。这使得扩音器成为相控阵雷达的理想选择。测量结果表明，在79 GHz工作电压为0.8 V时，信号增益为25.1 dB，饱和输出功率(Psat)为11.5 dBm，功率附加效率(PAE)为13.6%。这些结果与模拟结果一致。

A 76–81 GHz high efficiency power amplifier for phased array automotive radar applications

This paper describes the implementation of 76-81 GHz power amplifier (PA) in 65 nm CMOS technology. A customized transistor model enables the designing circuits operating at mm-wave band. The output matching of the PA was composed of low-pass network to reduce both footprint and matching loss. This makes the PA ideal for phased array radars. The measured results at 79 GHz achieved the small signal gain of 25.1 dB, the saturated output power (Psat) of 11.5 dBm, and the power added efficiency (PAE) of 13.6% at the supply voltage of 0.8 V. These results agreed with the simulation.
