本文提出了一种新型N路多频不等分威尔金森功率分配器(WPD)。分压器由多节传输线变压器 (TLT) 和隔离电阻组成，可在任意设计频率下同时提供高隔离度和非常好的输入/输出端口匹配。为了验证设计的有效性，设计并仿真了几种多频功率分配器。具体来说，设计了工作频率为900和1800MHz的三路不等分双频WPD、工作频率为1、2、3GHz的三路不等分三频WPD和工作频率为1、2、3、4GHz的四路等分四频WPD。
In this paper, a new N-way multi-frequency unequal split Wilkinson power divider (WPD) is proposed. The dividers are composed of multi-section transmission line transformers (TLT) and isolation resistors, which provide high isolation and very good input/output ports matching simultaneously at arbitrary design frequencies. To verify the validity of the design, several multi-frequency power dividers are designed and simulated. Speciflcally, a 3-way unequal split dual-frequency WPD operating at 900 and 1800MHz, a 3-way unequal split triple-frequency WPD operating at 1, 2, 3GHz, and a 4-way equal split quad-frequency WPD operating at 1, 2, 3, 4GHz, are designed.
