摘　　要：介绍了一种L波段150 W固态连续波功放的设计与实现。由于使用频带没有经济型的大功率功率管,设计过程中采用临近频带的大功率LDMOS功率管,采用动态阻抗匹配和ADS仿真相结合的方法进行跨频带匹配。采用微带巴伦进行分/合路,提高了模块的偶次谐波抑制,同时提高了模块的一致性。设计过程中采取了一系列的控制措施,提高模块的幅度相位一致性指标。制作调试了960~1 215 MHz频段150 W放大器,测试结果表明使用该方法设计放大器满足要求。This paper introduces the design and realization of an L-band 150W CW solid-state amplifier. Because the high power transistor is lack in the frequency used,during the design,the LDMOS high power transistor in near frequency is used,the frequencystrided matching is realized by combining dynamic state resistance matching and ADS simulation. The dividing / combining is implemented by adopting microstrip balun to reduce the even harmonious distortions and improve the coincidence indicator of module. In the design,a series of control ways are used to raise the coincidence indicator. a 960 MHz ~ 1 215 MHz frequency 150W amplifier is designed and debugged. The test results show that this method can be used for amplifier design.
