  • Electroacoustic filter comprising low-pass characteristics
    Patent number: 9667224
    Abstract: An electroacoustic filter has improved low-pass characteristics. The filter includes a first electroacoustic converter, an electroacoustic element and a grid structure between the converter and the element. The grid structure is acoustically active in one frequency range that lies above the acoustically active frequency range of the first electroacoustic converter.
    Type: Grant

  • Micro-acoustic filter having compensated cross-talk and method for compensation
    Patent number: 9362884
    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.
