摘要

本文提出了一种基于0.15μm GaAs技术的小型宽带变压器耦合功率放大器的设计。该功率放大器的输出功率为26.5dBm，功率增益为31%，小信号增益为12.6dB，分数带宽为40%。该放大器在28GHz频率下分别放大6Gb/s和9Gb/s 64-QAM信号，平均输出功率高达21.6dBm和19.9dBm, EVM<-25dB，无任何数字预失真。据作者所知，这是第一次在GaAs功率放大器中使用变压器耦合匹配网络，与笨重的传输线相比，匹配结构非常紧凑。

A Compact Ka-Band Transformer-Coupled Power Amplifier for 5G in 0.15um GaAs

In this paper we present the design of a compact and broadband transformer-coupled power amplifier in a 0.15μm GaAs technology. The power amplifier achieves an output power of 26.5dBm and 31% power added efficiency, 12.6dB of small signal gain with a fractional bandwidth of 40%. The amplifier enables up to 21.6dBm, 19.9dBm of average output power while amplifying a 6Gb/s, 9Gb/s 64-QAM signal respectively at 28GHz with an EVM<-25dB without any digital pre-distortion. To the author’s knowledge, this is the first time transformer-coupled matching networks are used in a GaAs power amplifier leading to very compact matching structures compared to bulky transmission line.
