TUNABLE SURFACE ACOUSTIC WAVE RESONATORS

摘要

A tunable SAW resonator circuit (400, 500) is disclosed. The tunable SAW resonator circuit includes a SAW resonator (404a, 404b, 504) having a quality factor and a resistor (412a, 414a, 510, 512) coupled to the SAW resonator to reduce the quality factor Q and a tuning component (402a, 502) 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 (402a, 502).
