摘要： The present invention provides a surface acoustic wave device that allows a plurality of surface acoustic wave filters to be formed on a single chip and permits greater miniaturization. The surface acoustic wave device comprises a piezoelectric substrate, a first surface acoustic wave resonator formed on the piezoelectric substrate, and a second surface acoustic wave resonator formed on the piezoelectric substrate in the surface acoustic wave propagation direction of the first surface acoustic wave resonator. The positions in which the first and second surface acoustic wave resonators are formed on the piezoelectric substrate are in an at least partially overlapping relationship in a surface acoustic wave propagation region that is defined by virtually extending the respective openings of the first and second surface acoustic wave resonators. The surface acoustic wave device further comprises a part for dividing the overlap surface acoustic wave propagation region into an upper half and a lower half and for affording the phases of surface acoustic waves that are propagated by the first surface acoustic wave resonator a mutually antiphase relationship in the upper-half region and lower-half region thus divided.

摘要： A SAW filter includes multiple SAW resonators. The multiple SAW resonators, which are connected in series, are connected any one of between a signal input terminal and a ground that is the closest thereto and between a signal output terminal and another ground that is the closest thereto. The SAW resonators have substantially equal electrostatic capacitances. It is thus possible to protect the SAW resonators without providing a sacrificial electrode for electrostatic breakdown, and thereby possible to configure the SAW filter having a high reliability against the electrostatic discharge.
