Abstract
An acoustic wave device comprises a piezoelectric substrate, interdigital transducer electrodes having an electrode pitch λ, and first and second reflector gratings disposed on opposite respective sides of the interdigital transducer electrodes in a propagation direction of a main acoustic wave through the acoustic wave device, the first reflector grating having a different electrode pitch λthan an electrode pitch λof the second reflector grating to suppress ripples in a conductance curve of the acoustic wave device.
