Abstract
An electromechanical filter having minimum attenuation deviation in the pass band frequency range. The filter includes a plurality of mechanical resonators arranged substantially parallel to each other in one plane and mechanical couplers of longitudinal resonance characteristics which are disposed substantially transverse to the plurality of resonators for coupling the resonators together. The couplers have lengths which are between the first and second, and second and third oscillation modes of the longitudinal resonance characteristics. By virtue of the above structure, the couplers can be formed in a single mechanical coupling wire.
