Abstract
Improved coupling coefficients and desirable filter characteristics are exhibited in a SAW filter including an electrode pattern deposited on a piezoelectric substrate bonded directly to an anti-reflective layer, wherein the anti-reflective layer is bonded to a carrier through an adhesive layer such that a preselected thickness of the anti-reflective layer is sufficient for enhancing an acoustic match between the piezoelectric substrate and the adhesive layer.
