摘要

提出了一种基于希夫曼移相器的宽带滤波均衡功率分配器。采用一个改进型威尔金森功率分配器和两个希夫曼移相器实现宽带均衡功率分配器。此外，通过在输入端口使用开放式存根来实现两个传输零，以实现滤波特性。设计并制作了一个以2ghz为中心的宽带滤波平衡功率分配器($\varepsilon_{\mathrm{r}}= 3.66,\ \mathrm{h}=0.762\ \text{mm},\ tan\delta=0.004$)进行验证。

Wideband Filtering Balun Power Divider Using Schiffman Phase Shifter

A novel wideband filtering balun power divider using Schiffman phase shifter is proposed. A modified Wilkinson power divider and two Schiffman phase shifters are adopted to realize wideband balun power divider. In addition, two transmission zeros are realized by using an open-ended stub at the input port to realize the filtering characteristic. A wideband filtering balun power divider ($\varepsilon_{\mathrm{r}}= 3.66,\ \mathrm{h}=0.762\ \text{mm},\ tan\delta=0.004$) centering at 2 GHz is designed and fabricated for verification.
