Abstract
A system that reduces crosstalk and return loss within electrical communication connectors includes at least two compensating capacitors connected in series that compensate each offending capacitor. An additional inductive component that is connected between two compensating capacitors so that the adjustable inductance of the inductive component can be varied to modify the capacitive coupling effect achieved by the compensating capacitors as a function of frequency. A shape-neutral structure containing two compensating capacitors and one series inductive component in between is positioned so that each compensating capacitor is juxtaposed parallel to the offending capacitor. There is no direct contact between the shape-neutral structure and the transmission lines, and the shape-neutral structure does not change the shape of PCB traces and reduces both crosstalk and return loss.
