摘要

介绍了一种用于28ghz LMDS应用的包络跟踪功率放大器(ET-PA)的设计与仿真。为了减小系统的失真，在数字域采用了线性化算法。仿真结果表明，ET-PA的输出功率为19dBm，线性增益为21dB。该放大器的功率增加效率超过41%，与传统LMDS放大器相比，效率提高了约15%。

A 28 GHz linear envelope tracking-power amplifier for LMDS applications

This paper presents the design and simulation of an envelope tracking power amplifier (ET-PA) for 28 GHz LMDS applications. A linearization algorithm is also employed in digital domain in order to reduce the distortion of the system. Simulation shows that proposed ET-PA delivers 19dBm output power with 21dB linear gain. Power added efficiency of this amplifier is more than 41% which shows about 15 percent efficiency enhancement compared to conventional LMDS PAs.
