Abstract
A surface acoustic wave resonator, a filter, a manufacturing method thereof and a communication device. The surface acoustic wave resonator includes a piezoelectric material layer, an interdigital transducer and a dielectric layer; the interdigital transducer is located at a side of the piezoelectric material layer, and the dielectric layer is located between the interdigital transducer and the piezoelectric material layer. Therefore, the surface acoustic wave resonator can reduce the electromechanical coupling coefficient of the surface acoustic wave resonator by arranging the dielectric layer between the interdigital transducer and the piezoelectric material layer. In addition, the surface acoustic wave resonator can adjust the electromechanical coupling coefficient of the surface acoustic wave resonator by controlling the thickness of the dielectric layer.
