Patent ID: 7218188

Claim:
A system comprising: a first circuit; an input surface acoustic wave (SAW) transducer on or above a piezoelectric substrate, the input SAW transducer coupled to the first circuit to receive an input signal and to generate an input SAW in the piezoelectric substrate from the input signal; an output SAW transducer on or above the piezoelectric substrate to receive the input SAW from the piezoelectric substrate and generate an output signal from the input SAW; a second circuit coupled to the output SAW transducer to receive and process the output signal; and a microelectromechanical system (MEMS) switch located between the input SAW transducer and the output SAW transducer, the MEMS switch having a deformable member to deform and mechanically contact the piezoelectric substrate to modify the input SAW generated by the input SAW transducer.
