Abstract
This invention relates to a surface acoustic wave device which is comprised of a single domain lithium niobate layer on a multiple domain lithium niobate substrate. On the single domain layer are launching and receiving interdigitated electrode patterns. Spurious responses generated by bulk waves from the launching electrode and transmitted to the receiving electrode are substantially reduced.
