| 摘 要： | 基于风云四号气象卫星地面站研制工作的需求,为了能够在甚高频和特高频频段下实现任意N路,任意带宽下的小体积功分器的设计,采用集总参数的Chebyshev阻抗变换网络代替传统功分器的λ/4传输线进行了分析和计算,并使用Agilent公司的高级设计系统(ADS)软件对电路进行仿真.仿真结果表明这种设计方法具有非常小的插入损耗和很高的隔离度,超出了预期的指标.基本满足工程设计的需求.

| Abstract: | Basing on the work of newly designed FY-4 Meteorological Satellite Ground Station,in order to get the design of mall-size power dividers working in VHF and UHF band with arbitrary ways and relative bandwidth,λ/4 transmission line is taken the place of the lumped parameter Chebyshev impedance transformation network in this paper.Designed circuit was simulated using Agilent's Advanced Design System(ADS) software,and a very low insertion loss and a high degree of isolation were got,and the results are better than the expected indicators.Basically met the engineering requirements. |
