Abstract:
Filter devices and duplexer devices are disclosed. A filter device includes two or more surface acoustic wave resonators, including at least a first shunt resonator, formed on a surface of a substrate. A ground conductor formed on the surface of the substrate connects the first shunt resonator to a ground pad. At least a portion of an edge of the ground conductor is shaped as a plurality of serrations.
