End face reflection type surface wave resonator |
摘要 |
An end face reflection type surface wave resonator utilizing a surface wave of an SH type is constructed by forming comb electrodes on one major surface of a piezoelectric substrate, which constitute an IDT, and forming grooves extending from one major surface to the other major surface to form a pair of end faces on which a surface wave is to be reflected the resonator having piezoelectric plate portions outside the grooves.
