Abstract
An SW resonator has a substrate of piezoelectric material. Two reflectors are applied onto the one substrate side. Input and output transducers are situated between the reflectors. The SW resonator is expanded to form an SW resonator having three electrical gates by arranging an additional transducer between the reflectors.
