A reconfigurable RF filter, which includes a first resonator, a second resonator, and a first coupling circuit, is disclosed. The first coupling circuit is coupled between the first resonator and the second resonator. The reconfigurable RF filter operates in one of a group of operating modes, which include a first operating mode and a second operating mode. During the first operating mode, the reconfigurable RF filter is a bandpass filter having a first bandwidth and a first insertion loss via the first resonator. During the second operating mode, the reconfigurable RF filter is a bandpass filter having a second bandwidth and a second insertion loss via the first resonator, such that the first bandwidth is greater than the second bandwidth and the first insertion loss is less than the second insertion loss.

Embodiments of resonator circuits and modulating resonators and are described generally herein. One or more acoustic wave resonators may be coupled in series or parallel to generate tunable filters. One or more acoustic wave resonances may be modulated by one or more capacitors or tunable capacitors. One or more acoustic wave modules may also be switchable in a filter. Other embodiments may be described and claimed.
