Design of Microwave Reconfigurable Equalizer Based on MEMS Technology

Abstract

In this paper, based on the design theory of CPW equalizer with low VSWR, microwave reconfigurable equalizers with various equalization curves have been designed. The combined structures of the reconfigurable equalizer with low VSWR and small sizes via MEMS switches have been optimized by ADS and HFSS software. The equalizer can be used in the frequency range from 20GHz to 24GHz. With the control of switches, the reconfigurable equalizer can realize the variation of the equalization curves and achieve the minimal insertion losses of around-1dB, respectively. In order to improve the minimal insertion losses, a matched structure has been presented. The matched structure reduces the minimal insertion losses compared with the former structure significantly.
