摘　　要：随着射频系统带宽的增加,如何达到良好的幅频特性成为研究的课题之一。介绍了一种用微带线均衡网络改善雷达发射机射频放大器幅频特性的方法,分析了该均衡网络的工作原理。通过仿真分析,对电路模型进行了改进并在某L频段放大器上对结果进行了验证。由于结构简单易调整,此均衡网络可方便地应用于功放组件内部。With the increasing of RF bandwidth, how to achieve good amplitude - frequency characteristics becomes a key research issue. The method using mierostrip line equipoising network to improve the ampli- tude - frequency characteristics of radar transmitter RF amplifier is discussed in this paper, then the oper- ating principle of this equipoising network is analyzed. The circuit model is improved, and its result inan L band amplifier is verified by simulation. This equipoising network can be applied in power amplifiers con- veniently due to its simple structure and easy adjustability.
