Abstract
The invention relates to a micro-acoustic filter having a first and a second converter, in which the electromagnetic and capacitive cross-talk between the first and second converters is compensated for by providing additional coupling capacitors and additional current loops. Additional coupling capacitors and current loops are arranged in such a manner that they can counteract the sign of the natural coupling specified by the design and thus completely compensate for said coupling.
