Abstract
A filter circuit has a resonator circuit with a first acoustic resonator and a second acoustic resonator connected in series on a printed circuit board (PCB). The filter circuit also has a composite resonator circuit formed by a capacitor connected in parallel with the second acoustic resonator on the PCB. The capacitor is configured to improve a steepness of an upper bandpass edge of the filter circuit.
