介绍了一种工程上已经使用的 Ｓ波段，输出脉冲功率大于３００ Ｗ 、工作带宽达 ４００ Ｍ Ｈｚ的固态功率放大器。该功放运用了模块化的设计方法，提高了功放的可靠性。

This paper introduces a solid-state power amplifier which has been used in engineering application .The output pulse power is more than 300W,the instantaneous operating bandwidth is as wide as 400MHz.A new modular design method was used in this power amplifier ,so high reliability has been assured.
