摘要:
Systems and method for wideband filter designs comprising two-port piezoelectric resonators electrically coupled in parallel. A resonating circuit comprises a first piezoelectric resonator formed of a first configuration, and a second piezoelectric resonator formed of a second configuration such that outputs of the first and second piezoelectric resonators have a 180-degree phase difference for a same input. The first piezoelectric resonator and the second piezoelectric resonator are coupled electrically in parallel. The first and second piezoelectric resonators have different resonating frequencies respectively controlled by lateral dimensions of the piezoelectric resonators.
