SAW resonator having a broad bandwidth

摘要: A SAW resonator includes resonating transducer units formed on a piezoelectric substrate and juxtaposed in direction of propagation acoustic waves, unidirectionally reflecting unit provided each end the substrate. Each first second transducers connected series and/or parallel with other. comb-like electrodes having plurality fingers, respectively, substrate, which: two fingers are interposed between pair adjacent fingers; at least one reflective stripe is distances widths determined such that waves produced by propagating perpendicular to length reflected phase out direction.
