ABSTRACT:
A printed circuit board having a dielectric layer is disclosed. At least one signal trace is disposed adjacent a first surface of the dielectric layer in a first signal area. A reference plane is disposed adjacent a second surface of the dielectric layer in a first reference area positioned opposite the first signal area. The reference plane is configured to carry a reference potential for signals on the signal trace. At least one other signal trace is disposed adjacent the second surface of the dielectric layer in a second signal area and coupled to the signal trace in said first signal area. A second reference plane is disposed adjacent the first surface of the first dielectric layer in a second reference area positioned opposite the second signal area. The second reference plane is configured to carry the reference potential for signals on the other signal trace.
