ABSTRACT:
A mode-converting type bulk acoustic wave delay line adapted to suppress triple transit signals and provide response tailoring, the device including a body of acoustic wave supporting material with at least one mode-converting planar surface capable of reversably converting longitudinal wave mode acoustic energy to shear wave mode acoustic energy, the device also including an attenuating structure disposed on the mode-converting planar surface for absorbing a predetermined amount of propagating shear wave mode energy and thereby increase insertion loss.
