摘要: A component operating with surface-proximal acoustic waves, in particular a filter with novel structure, has interdigital transducers arranged in serial and parallel branches, which are acoustically coupled with one another in different configurations. The component provides a loss-poor filter with simultaneously space-saving arrangement of the filter elements.
