ABSTRACT:
A differential-mode signal transmission system includes a circuitboard composed of at least one dielectric board substrate and a pair of spaced apart conductive parallel planar signal transmission lines disposed on one surface of the substrate and extending between a pair of edges thereof for providing pass-through transmission of differential-mode signals from one to the opposite edge of the substrate. Preferably, the circuitboard is composed of at least a pair of dielectric board substrates being disposed in face-to-face layered contact with one another and having at least one pair of the spaced apart conductive parallel planar signal transmission lines disposed between the layered substrates along the inner surfaces thereof. Ground planes are provided on the outer surfaces of the layered substrates for electrically shielding the parallel planar transmission line pair. Connectors in the form of spaced pairs of conductively plated through holes being electrically isolated from the ground planes on substrate outer surfaces are provided through the substrates and electrically connected to the parallel planar transmission lines for facilitating connection of electrical components thereto.
