Abstract

This paper is focused on the creation of an efficient electromagnetic model of MEMS switches which operates at microwave frequencies. The switches are first characterized using a full wave analysis based on finite element method aiming to extract the S-parameters of the switches for different geometrical dimensions. From the S-parameter data base, a scalable lumped circuit model is extracted to allow easy implementation of the switch model into available microwave CAD software. The simulated results are compared with published measured data as validation of our model.

微波频率下MEMS电容开关的参数化模型
本文的重点是建立一个有效的电磁模型的MEMS开关工作在微波频率。首先采用基于有限元的全波分析方法对开关进行表征,提取开关在不同几何尺寸下的s参数。从s参数数据库中提取可扩展的集总电路模型,以便将开关模型轻松实现到可用的微波CAD软件中。仿真结果与已发表的实测数据进行了比较,验证了模型的有效性。
