▎ 摘　　要

NOVELTY - The invention claims a surface acoustic wave resonator and a filter comprising the surface acoustic wave resonator, the surface acoustic wave resonator comprises: a piezoelectric film layer and an electrode formed on the piezoelectric film layer, wherein the electrode is formed with a soaking layer, the soaking layer is at least partially covered on the electrode, the soaking layer is a graphene layer, the filter is cascaded by the surface acoustic wave resonator to form a high thermal conductivity of the graphene layer, It avoids the bad phenomenon of partial overheating when the electrode, the surface acoustic wave resonator and the filter work in a certain degree. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for an acoustic surface wave filter.
