In this letter, an ultrawideband (UWB) bandpass Wilkinson power divider (WPD) is introduced. By using filter synthesis theory and proposed optimization algorithm, all the $S$ -parameters ( $S_{11}$ , $S_{21} = {S} _{31}$ , $S_{22} = {S} _{33}$ and $S_{32}$ ) of the proposed topology could provide an equal-ripple response, and their equal-ripple level and bandwidth can be controlled, respectively. For verification purposes, a prototype UWB WPD has been simulated, fabricated, and measured. The measured and simulated results are matched reasonably well.

一种可控等纹波电平的超宽带带通威尔金森功率分配器优化算法

在这封信中，介绍了超宽带 (UWB) 带通威尔金森功率分配器 (WPD)。通过使用滤波器合成理论和提出的优化算法，所有的 $S$ -参数 （ $S_{11}$ , $S_{21} = {S} _{31}$ , $S_{22} = {S} _{33}$ 和 $S_{32}$ ) 所提出的拓扑结构可以提供等纹波响应，并且可以分别控制它们的等纹波电平和带宽。出于验证目的，已经对原型 UWB WPD 进行了模拟、制造和测量。测量结果和模拟结果相当匹配。
