ABSTRACT:
Disclosed is a device for reducing crosstalk in an electrical connector. The device includes an insulating board with a plurality of layers. A first plurality of pairs of conductive paths is formed on a surface of at least one layer, and a second plurality of pairs of conductive paths is vertically spaced therefrom. The paths are arranged so that at least one conductive path in the first plurality of pairs overlies at least two conductive paths from different pairs in the second plurality of pairs. The capacitive coupling between the paths results in crosstalk having a polarity opposite to that of the connector so as to compensate for the connector crosstalk.
