Abstract
An acoustic wave device is disclosed. The acoustic wave device can include a support substrate that includes a first substrate portion, a second substrate portion, and a third substrate portion between the first substrate portion and the second substrate portion. The acoustic wave device can include a piezoelectric layer that includes a first portion over the first substrate portion and a second portion over the second substrate portion. The piezoelectric layer can be arranged such that a region over the third substrate portion is free from the piezoelectric layer. The acoustic wave device can include a filter circuit formed on the first portion of the piezoelectric layer. The acoustic wave device can include a cancelation circuit on the second portion of the piezoelectric layer.
