小型化任意相位差功率分配器设计

摘要

提出了一种小型化的任意相位差功率分配器结构。该电路结构由五段微带线和1个匹配电阻组成。通过调节传输线段的设计参数，该功率分配器可以实现指定的相位差和功分比信号输出。利用奇偶模分析技术，推导出了该结构的闭式计算公式。为了验证该结构的可行性，在1 GHz工作频率上对其进行了两次建模仿真。研究结果证明：该设计可以实现两路功率比和相位差可控的信号输出。%A miniaturization power divider with arbitrary output phase difference is presented. The circuit structure consists of five microstrip lines and a matching resister. By tuning the design parameters of every transmission line , the proposed power divider can produce the required phase difference and power division outputs. Using the even-odd mode analysis method,the closed-form design equation of this structure is deduced. To demonstrate the validity of this structure,two simulations of this model are operated at 1 GHz. The research results prove that this design can realize two controllable power division and phase difference signal outputs.
