Bulk acoustic-wave component, has electrically isolated layer, which is arranged between two conductors and includes coupling, where another coupling is larger than former coupling

摘要

The component has structures (21,22) that are conductively connected with one another using a conductor (2). One of the structures forms an electrode of a thin film resonator having a layer with an electro acoustic coupling. The two conductors intersect in an intersection area. An electrically isolated layer (31) arranged between the conductors has another coupling, where the former coupling is larger than the latter coupling.
