摘　　要：功率分配器是通信系统中常用的器件,由于通信设备对电路尺寸及工作频率的要求,双频及多频应用正逐渐增多。基于经典的Wilkinson功率分配器,采用了阶梯阻抗变换器结构,并在输入端并联微带线分支结构,设计了一种新型的工作在双频段的功率分配器。采用ADS Momentum仿真,综合考虑了微带线间的耦合效应,经过优化取得了良好的特性。所提到的设计方法可以应用到各不同频率点的场合以符合具体要求。Power divider is a general component in communication system. Due to the restriction on circuit real estate and working frequency,there is an increase in dual- band and multi -band applications. This paper presents a new type of dualband power divider based on the traditional Wilkinson structure. It comprises a transformer in two sections with a shunt stub in the input port. Using ADS Momentum, considering the effect of coupling between microstirp lines. After optimization,a perfect performance is achieved and this method can be easily used in many different circumstances with different specifics.
