Abstract: Techniques are disclosed implementing acoustic wave resonator (AWR) filter architectures to enable integrated solutions requiring significantly less passive components. The primary AWR filter topology leverages the use of parallel resonator branches, each having a relatively narrow bandwidth that may be combined to form an overall broadband filter response. This architecture may be further modified using electronically-controlled switching components to dynamically turn specific branches on or off to tune the filter, thus realizing a programmable broadband solution. Shunt resonators may also be added to the AWR filter topology, which may also be controlled with the use of electronically-controlled switching components to provide further control with respect to roll-off and the location and number of notch frequencies.
