Abstract
A SAW architecture is provided with two acoustic reflectors formed on a piezoelectric substrate defining an acoustic cavity between the acoustic reflectors. At least one alpha IDT may be provided, and at least three beta IDTs are provided. These IDTs are placed in acoustic series within the acoustic cavity. The alpha IDT is electrically coupled to a first interface. The beta IDTs are coupled in electrical and acoustic series and associated with a second interface. In certain embodiments, the at least three beta IDTs are adjacent one another, while in other embodiments an additional reflector or an alpha IDT may be placed between two beta IDTs. The beta IDTs include two outer beta IDTs and an inner beta IDT located between the two outer beta IDTs. The inner beta IDT may be chirped in a center portion, wherein the area outside of the center portion is not chirped.
