Abstract
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.

A tunable resonator module comprising a variable capacitor coupled in parallel with a resonator module including one or more resonators and one or more switches to switch in or switch out corresponding one or more resonators:
- wherein the tunable resonator module is implementable in a:
- A) series configuration wherein:
- a1) a passband of the tunable resonator module:
- i) is a function of a fixed resonant frequency of each resonators of the one or more resonators;
- and
- ii) is to be modulated by closing and/or opening switches of the one or more switches to bypass and/or include resonators of the one or more resonators, and
- a2) a stopband of the tunable resonator module is to be modulated by varying the variable capacitor;
- and/or
- B) shunt configuration wherein:
- b1) a stopband of the tunable resonator module:
- i) is a function of a fixed resonant frequency of each resonator of the one or more resonators;
- and
- ii) is to be modulated by closing and/or opening switches of the one or more switches to bypass and/or include resonators of the one or more resonators;
- b2) a passband of the tunable resonator module:
- iii) is a function of the fixed anti-resonant frequency of each resonators of the one or more resonators, and
- vi) is to be modulated by the variable capacitor.
