Filters based on bulk acoustic wave resonators present very good performance, small size and compatibility with IC technology. However, the traditional configurations present only one frequency transmission band. In this work, a configuration based on electrically coupled BAW resonators has been developed in order to obtain a dual-band response, where each of these bands can be allocated at a desired frequency. In order to validate the proposed topology, a filter response using measured resonators is shown.
