大功率限幅器的研制

介绍了一种L波段大功率限幅器的研制情况,该限幅器具有体积小、插入损耗小、输入承受功率高及限幅输出电平低等特点。文中给出了限幅二极管在高/低输入信号电平时的等效电路以及同轴滤波器的设计分析过程。实验测试结果表明,限幅器完全达到技术指标要求。

Design of high power limiter

The development of a high power limiter is described in the paper.The limiter has the features of small size,low insertion loss,strong ability of handling high input power and low limited output level.In the paper,the equivalent circuits of the PIN-limiter diode at high/low input signal level are described.And the design process of the coaxial-filter is given,too.The experiment and test results are in good accordance with the requirements and performance data of the limiter.
