Abstract
A tunable filter using acoustic resonators is disclosed. A tunable filter includes a plurality of tunable resonator units (). Each tunable resonator unit () has acoustic wave resonators (). Each acoustic wave resonator is associated with a different tunable frequency. Each tunable resonator unit also has a first switch () configured to select one of the plurality of acoustic wave resonators of the tunable resonator unit at a time. The first switches of the plurality of tunable resonator units are coupled to cooperatively select one acoustic wave resonator in each one of the plurality of tunable resonator units, where a selected acoustic wave resonator in a tunable resonator unit of the plurality of tunable acoustic resonator units is associated with a same tunable frequency response as the other selected acoustic resonators of the others of the plurality of tunable acoustic resonator units. The selection results in an overall tunable frequency response.
