ABSTRACT:
A pass-band electromechanical filter, comprising a mechanical unit vibrating in the longitudinal mode mounted between two electromechanical transducers, said unit comprising a plurality of half wave resonators mounted in series and coupling rods connecting the consecutive resonators, the resonators being distributed into two groups of which one comprises the resonators of odd rank and the other the resonators of even rank, the filter comprising moreover at least a bridging coupling rod connecting a resonator of rank k to a resonator of rank k+(2p+1) (p being a positive integer different from zero), said bridging coupling rod having its ends fixed at a certain distance from the end faces of the resonators, at least the bridging coupling rod on the one hand, or the coupling rod placed between the resonator of rank k and that of rank k+(2p+1) on the other hand, having a length which is respectively different from a three quarter wave or different from a quarter wave.
