A Systematic Design Method for Band-Pass Filters Composed of Film Bulk Acoustic Resonators

Abstract

We propose a systematic method to design band-pass filters composed of film bulk acoustic resonators (FBARs), for wireless communication. FBARs have demonstrated excellent performance due to their compact size, low loss, power endurance and IC compatibility. Modifying the traditional Butterworth theory, the ladder-type band-pass filters can be composed of… (More)
