Abstract: The RF filters used in conventional mobile devices often include resonator structures, which often require free-standing air-gap structure to prevent mechanical vibrations of the resonator from being damped by a bulk material. A method for fabricating a resonator structure comprises depositing a non-conformal thin-film to the resonator structure to seal air gap cavities in the resonator structure.

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.

Abstract: In one embodiment, a resonator device includes a substrate comprising a piezoelectric material and a set of electrodes on the substrate. The electrodes are in parallel and a width of the electrodes is equal to a distance between the electrodes. The resonator device further includes a set of switches, with each switch coupled to a respective electrode. The switches are to connect to opposite terminals of an alternating current (AC) signal source and select between the terminals of the AC signal source based on an input signal.
