Aspects and embodiments disclosed herein include an acoustic wave device comprising a substrate, a pair of IDT electrodes formed on the substrate, a respective finger of one IDT electrode being separated from an adjacent finger of the other IDT electrode by a first pitch distance, and reflectors formed on the substrate interposing the pair of IDT electrodes therebetween, the reflectors and the pair of IDT electrodes arranged along a propagation direction of a main acoustic wave, each of the reflectors including a plurality of fingers separated from each other by a second pitch distance and extending in a same direction of extension as the plurality of fingers of the pair of IDT electrodes.
