摘要:
为了设计出结构紧凑且制作加工灵活方便的双频功分器结构,该文提出了一种基于短 路短截线加载耦合微带线( Shorted stub loaded coupled microstrip lines,SS-CML) 单元的新型双频 Wilkinson 功分器。在运用奇偶模分析法对SS-CML 单元的等效相位及等效特性阻抗分析的基 础上,推导出采用该单元设计双频Wilkinson 功分器的解析公式,讨论了该功分器工作频率比的 适用范围。最后设计加工并测试了一个工作于1. 43 GHz 和2. 57 GHz 的双频Wilkinson 功分 器,测试与仿真结果吻合良好。该功分器可适用于工作频率比较小的情况。
Abstract:
This paper presents a novel dual-band Wilkinson power divider based on a unit of shorted stub loaded coupled microstrip lines( SS-CML) for compact size and easy fabrication. By analyzing the equivalent phase and the equivalent characteristic impedance of the SS-CML unit with an evenodd mode analysis method, the rigorous equations for dual-band Wilkinson power divider design are derived and the frequency ratio range for the power divider is discussed. Finally,a dual-band Wilkinson power divider operating at 1. 43 GHz and 2. 57 GHz is designed, fabricated and measured. Good agreement is achieved between the simulation results and the measurements. The proposed power divider is suitable for small frequency ratio applications.
