Abstract: There is disclosed an improved electromechanical resonator for use in multiresonator mechanical bandpass filters. The resonator is constructed using two resonator rods attached to a ceramic transducer which is substantially centrally located. The thus-formed electromechanical resonator resonates at the desired frequency in the third torsional mode, which is characterized by three motional nodes. Support pins are attached at the two outer nodes to provide physical support, and are also used for signal and ground connections, while the ceramic is positioned on or near the center node, which maximizes the achievable electromechanical coupling. Multiresonator mechanical bandpass filters which use such third-mode electromechanical resonators in conjunction with second-mode interior resonators have improved spurious rejection.
