Abstract:
Apparatus useable for compensating an imbalance between a first differential pair which includes first and second conductors for carrying a first differential signal pair and a second differential pair which includes third and fourth conductors for carrying a second differential signal pair, comprising:a circuit board formed of a first circuit board material, defining first and second major surfaces, said circuit board having a first thickness; a first substantially conductive area formed on said second major surface of said circuit board substantially aligned with and spaced from a first portion of said second differential pair, said first substantially conductive area being spaced from said second differential pair by a predetermined thickness of said first circuit board material, and spaced laterally a predetermined distance from said first differential pair on said first major surface; and a substantially conductive pathway from said first substantially conductive area to said first conductor configured to increase capacitive coupling between said first conductor and said second differential pair.
