摘要

本文介绍了一种1.5 kW固态脉冲功率放大器的设计和性能,工作频率为2.7-2.9 GHz,占空率为10%,脉冲宽度为100 us,用于雷达应用。固态脉冲功率放大器配置一系列8级级联功率放大器,具有不同的射频输出功率电平。低损耗威尔金森合成器用于组合6个300w大功率固态模块的输出功率。测试表明,峰值输出功率为1.61 kW,在2.7-2.9 GHz范围内,脉冲宽度为100 us, PRF为1 kHz, PAE为26.2%。

1.5 kW solid-state pulsed microwave power amplifier for S-band radar application
This paper describes the design and performance of a 1.5 kW solid-state pulsed power amplifier, operating over 2.7-2.9 GHz at a duty of 10 percent and with a pulse width of 100 us for radar application. The solid-state pulsed power amplifier configures a series of 8-stage cascaded power amplifiers with different RF output power levels. Low loss Wilkinson combiners are used to combine output powers of six 300 W high power solid state modules. Tests show peak output power of 1.61 kW, corresponding to PAE of 26.2 % over 2.7-2.9 GHz with a pulse width of 100 us and a PRF of 1 kHz.
