Piezoelectric resonator with acoustic surface wave on a piezoelectric base, containing a digital converter placed on the surface of the base between two reflecting structures, characterized in that it contains a piezoelectric base with crystallographic orientation, where there are two surface modes with different speeds of propagation, one of them having piezoelectric coupling, while in the base are situated periodic coupling structures, within whose area Bragg reflection takes place with simultaneous conversion of the two different propagating modes.
