Surface acoustic wave device |
摘要 |
A surface acoustic wave device includes a surface acoustic wave resonator. The surface acoustic wave resonator includes comb-like electrodes and reflection electrodes provided on both sides of the comb-like electrodes, and each of the reflection electrodes has at least two different pitches. It is thus possible to suppress the ripple components.
