摘要

本文提出了一种高功率(320瓦)、高效率(大于56%)的基于LDMOS的功率放大器结构。基于MRF8P29300的非线性模型，设计了一种针对s波段的小型ab类放大器。除了使用ADS进行优化外，还使用混合耦合器提高了放大器的性能，提供了56 dBm的输出功率。除了设计细节外，本文还介绍了电磁和热分析，以便更好地理解放大器的特性。实测结果表明，该放大器增益达到14dB，增益平坦度<0.7dB，输入/输出回波损耗<-12dB;这使得所提出的放大器成为监视和跟踪雷达的理想选择。

Miniaturized High-Efficiency Pulsed-Power Amplifier for Surveillance and Tracking Radar

In this article a high power (320 watt), high efficiency (greater than 56 %) LDMOS based power amplifier configuration is proposed. Proposed compact class-AB amplifier is designed using non-linear model of MRF8P29300, targeting S-band. Along with optimization using ADS, hybrid couplers are used to improve the performance of proposed amplifier, providing output power of 56 dBm. Other than design details, paper also present electromagnetic and thermal analysis for better understanding of amplifier characteristics. Moreover, measured results indicate that proposed amplifier achieved 14dB gain, gain flatness <0.7dB and input/output return loss <-12dB; which make proposed amplifier worthy and prospective candidate for surveillance and tracking radars.
