Claim 10:
11. An electronic device comprising:
an electronics module including a radio frequency filter, the radio frequency filter including an acoustic wave resonator including a piezoelectric substrate, interdigital transducer electrodes having an electrode pitch λ0, 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 λ1 than an electrode pitch λ2 of the second reflector grating to suppress ripples in a conductance curve of the acoustic wave resonator, each of λ1 and λ2 being greater than λ0 by between about 2% and about 5%.
