Abstract

A Bleustein-Gulyaev-Shimizu (BGS) wave has only a shear horizontal (SH) wave showing a complete reflection at a free edge of a substrate. By utilizing this property, a small BGS resonator having one resonance without reflector electrodes is realized. In this paper, using the responses exited by a weighted interdigital transducer (IDT) and generated by the 2N±2th mode's complete reflections at free edges of a ceramic substrate, we realized a new type of BGS resonator having resonances without reflector electrodes. This resonator showed sufficient trap attenuations for practical use at both adjacent picture carrier frequency (fap) and adjacent sound carrier one (fas) in the TV and VCR video intermediate frequency (VIF) circuit.
