Electrical connectors and printed circuits having broadside-coupling regions
First Claim
1. A printed circuit configured to communicatively couple to mating and loading conductors, the printed circuit comprising:
- a dielectric substrate that has opposite surfaces and a thickness measured along an orientation axis extending between the opposite surfaces;
associated pairs of input and output terminals attached to the dielectric substrate, the input terminals being configured to communicatively couple to the mating conductors and the output terminals being configured to communicatively couple to the loading conductors; and
signal traces electrically connecting the associated pairs of input and output terminals, each of the signal traces defining a respective width, the signal traces comprising differential pairs, wherein each associated pair of input and output terminals is electrically connected through a corresponding signal trace that has a conductive path extending along the dielectric substrate between the corresponding input and output terminals, at least two signal traces from separate differential pairs forming a broadside-coupling region in which the conductive paths of the at least two signal traces change direction at least twice, wherein the widths of the at least two signal traces at least partially overlap and are spaced apart from one another along the orientation axis and extend parallel to each other through the broadside-coupling region for a crosstalk-reducing distance.

Abstract
An electrical connector that includes a circuit board having a board substrate that has opposite board surfaces and a thickness measured along an orientation axis that extends between the opposite board surfaces. The circuit board has associated pairs of input and output terminals and signal traces that electrically connect the associated pairs of input and output terminals. The input and output terminals being configured to communicatively coupled to mating and cable conductors, respectively. Each associated pair of input and output terminals is electrically connected through a corresponding signal trace that has a conductive path extending along the board substrate between the corresponding input and output terminals. At least two signal traces form a broadside-coupling region in which the conductive paths of the at least two signal traces are stacked along the orientation axis and spaced apart through the thickness and extend parallel to each other for a crosstalk-reducing distance.
