Title: 1-port type surface acoustic wave device

Abstract: A 1-port type surface acoustic wave device can be produced by using the same tools as used for the production of a 2-port type surface acoustic wave device and achieves a substantial improvement in terms of impact resistance. A 1-port surface acoustic wave resonator includes a surface acoustic wave substrate, two dummy bump electrodes and two input/output bump electrodes disposed on the surface acoustic wave substrate adjacent to a plurality of input/output extraction electrodes.
