本文提出了一种工作在任意双频段、无无功元件(如电感和电容器)的不等Wilkinson功分器。为了满足这种不均匀特性,提出了一种采用两组传输线和两个平行短节的新型结构。基于电路理论和传输线理论,推导出包含该结构所有参数的闭合方程。为了验证,给出了开路和短路两组实验结果。结果表明,该不等功率分配器在任意双频段均可同时满足所有的分析特性。
This paper presents an unequal Wilkinson power divider operating at arbitrary dual band without reactive components (such as inductors and capacitors). To satisfy the unequal characteristic, a novel structure is proposed with two groups of transmission lines and two parallel stubs. Closed-form equations containing all parameters of this structure are derived based on circuit theory and transmission line theory. For verification, two groups of experimental results including open and short stubs are presented. It can be found that all the analytical features of this unequal power divider can be fulfilled at arbitrary dual band simultaneously.
