Elastic wave duplexer having a sealing member that includes a recess
Abstract:
In an elastic wave duplexer, a reception elastic wave filter element and a transmission elastic wave filter element are flip-chip mounted to a principal surface of a substrate. A sealing member is disposed on the principal surface of the substrate to cover and seal off at least one of the reception elastic wave filter element and the transmission elastic wave filter element. The sealing member has different thicknesses between a reception-element-covering region, which faces the reception elastic wave filter element on the side opposite from the substrate with respect to the reception elastic wave filter element, and a transmission-element-covering region, which faces the transmission elastic wave filter element on the side opposite from the substrate with respect to the transmission elastic wave filter element.
