Abstract:
RF circuitry, which includes a first acoustic RF resonator (ARFR) and a first compensating ARFR, is disclosed. A first inductive element is coupled between the first compensating ARFR and a first end of the first ARFR. A second inductive element is coupled between the first compensating ARFR and a second end of the first ARFR. The first compensating ARFR, the first inductive element, and the second inductive element at least partially compensate for a parallel capacitance of the first ARFR.
