20130257220 | SURFACE ACOUSTIC WAVE COMPONENT - A surface acoustic wave component contains two fan-shaped interdigital transducers disposed on a piezoelectric substrate, the prongs and gaps of which transducers forming groups having the same length, called cells, between them, and narrow in the averaged prong direction. The cells are structured like cells of unidirectional transducers, and at least one of the fan-shaped interdigital transducers is composed of partial transducers. The partial transducers are disposed one behind the other, perpendicular to the averaged prong direction. | 10-03-2013 |
