Abstract
A tunable SAW resonator circuit is disclosed. The tunable SAW resonator circuit includes a SAW resonator having a Q, a resistor coupled to the SAW resonator to reduce the Q, and a tuning component coupled to the SAW resonator to tune the SAW resonator. A method to tune the SAW resonator is also disclosed. The SAW resonator may be tuned by applying a control signal to the tuning component.
