| Zusammenfassung: | A surface acoustic wave (SAW) device includes: a base substrate; a piezo-electric material layer; at least one interdigitated electrode pair disposed on the piezo-electric material layer; and an acoustic wave suppression layer disposed between the piezo-electric material layer and the base substrate, the acoustic wave suppression layer being configured to suppress an acoustic wave propagating in a direction from the piezo-electric material layer to the base substrate. |
