ABSTRACT:
A filter structure comprises a filter having an input port and an output port and a carrier to which the filter is attached having a reference potential area. The input port includes a first pad for receiving an input signal and a second pad for a first reference potential related to the input signal. The output port has a third pad for outputting an output signal and a fourth pad for a second reference potential related to the output signal. A first connecting wire contacts the second pad at a first connection point and the reference potential area at a second connection point. A second connecting wire contacts the fourth pad at a third connection point and contacts the reference potential area at a fourth connection point. A distance between the second and the fourth connection point is smaller than a distance between the first and the third connection point.
