新型的腔体滤波器设计分析

一种新型的腔体滤波器设计分析

内容简介：针对腔体滤波器的工程设计，分析了Designer和高频结构仿真软件（HFSS）的相互补偿作用，提出了一种全新的设计方法一网络参数分解法，详细论述了应用Designer进行原理仿真、HFSS整体验证以及同时应用这2个软件进行元件仿真的设计过程。给出一个Ku频段低通滤波器的设计实例，仿真结果表明，这种设计方法思路简单，设计效率高，结果更精确。

Abstract：Based on the engineering design of microwave filters,the mutual compensation effect of HFSS and the Designer is ana lyzed, and a novel design based on network parameter decomposing is presented. The design process is discussed in detail,including ele mentary diagram simulation by Designer,overall verification by HFSS,and simulation based on both Designer and HFSS. Finally,a de sign case of a lowpass filter in Kuband is given. Simulation results show that this method provides simplified concepts,higher efficiency and better precision.
