Abstract
An acoustic cavity of a surface acoustic wave (SAW) architecture is defined on a piezoelectric substrate by two acoustic reflectors are formed on a piezoelectric substrate. The surface acoustic wave architecture may include at least one alpha interdigitated transducer (IDT) at least three beta IDTs which 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 are associated with a second interface. At least three beta IDTs are adjacent one another. An additional reflector or an alpha IDT may be placed between two of the beta IDTs.
