摘要
文中采用多节Wilkinson结构,研制了一个工作频段在2~8GHz的超宽带功分器,并使用ADS与HFSS软件进行仿真和优化设计。在此基础上进行了实验验证,仿真结果和实物测试结果比较接近。测试结果表明该功分器工作频率内具有较好的性能指标,插入损耗小于3.5dB,端口回波损耗小于-15dB,输出隔离度大于20dB。
A UWB power divider with the frequency range from 2 GHz to 8 GHz is designed by using multi-class Wilkinson structure in this paper.The ADS and HFSS software are both used to simulate and optimize the power divider.A prototype of the power divider was fabricated and measured,the results of the simulation approximately coincide with the divider testing.The experimental results show excellent performance that the input-to-output insertion loss is less than 3.5 d B,the port return loss is more than 15 d B,and the output-to-output isolation is more than 20 dB in the operating frequency band.
