Abstract

Filters based on bulk acoustic wave (BAW) resonators are called to replace actual surface acoustic wave filters. The transmission response of BAW-based ladder-type filters presents a steep rejection near the passband, but a poor out-of-band (OoB) rejection. This article describes how modifying the basic configuration of this type of filters, its QoB rejection can be Improved. © 2007 Wiley Periodicals, Inc.
