Component for resonators, delay lines, HF-filter has a substrate, which has a piezoelectric layer and has a electrically conducting structure for generating, guiding or reflecting of acoustic waves in the piezoelectric layer

摘要

Component has a substrate, which has a piezoelectric layer and has a electrically conducting structure for generating, guiding or reflecting of acoustic waves in the piezoelectric layer. The relative geometrical arrangement of the electrically conductive structure is alterable opposite to the piezoelectric layer. An independent claim is also included for the method for frequency adjustment of a SAW, BAW or GBAW components.
