摘要
介绍了Wilkinson功分器的设计方法,研制了一个工作频段在4～12GHz的带状线型宽带功分器,采用多节λ/4阻抗变换器级联,实现了功分器频带的展宽。仿真结果和测试结果比较表明,功分器在如此宽的频带范围内仍能满足良好的性能指标,隔离度在整个频带范围内均在20dB以上,输入、输出端口均达到良好的匹配。
This paper introduces a novel method of broadening the frequency range of a power divider and stripline using a quarter-wavelength cascaded impedance convertor. A Wilkinson power divider with the frequency range from 4 GHz to 12 GHz is designed. The performance of the power divider over the a wide band is simulated and measured, and produces satisfactory results of more than 20 dB isolation between two output ports and a good match at both input and output ports.
