FIELD: radio engineering.
SUBSTANCE: invention relates to radio engineering and can be used to produce SHF oscillators. Surface-acoustic-wave resonator with grooves consists of a piezo-p.c.b with at least, one interdigital transducer and at least two reflecting structures arranged on its surface. These structures represent a system of grooves. At least one groove is made on piezo-p.c.b back side, between aforesaid reflecting structures on the way of surface-acoustic-waves.
EFFECT: higher Q-factor.
