摘要

提出了一种l波段20% BW脉冲功率放大器，输出功率为1KW。放大电路采用500W NXP-LDMOS器件的组合，通过使用简单的多段微带(Duroid 6006)混合电路。瞬时占空比为1:10，最大脉冲持续时间为1ms。该拓扑结构的传输增益为34dB，回波损耗优于30dB，效率为40%，适用于基于sspa的雷达应用。

1 KW compact L-band pulsed power amplifier for Radar applications

An L-band 20% BW pulsed power amplifier that provides 1KW output power is presented. The amplifier circuit uses a combination of 500W NXP-LDMOS devices through the use of simple multi-section microstrip (Duroid 6006) hybrids. Instantaneous duty cycle is 1:10 with a maximum pulse duration of 1ms. This topology exhibits a transfer gain of 34dB, return losses better than 30dB along with an efficiency located in the range of 40%, which is suitable for SSPA-based Radar applications.
