Abstract:
1. A coupling structure comprising: a first substrate; a first differential pad and a second differential pad arranged as a pair and coupled to the first substrate; an insulating layer having opposing top and bottom surfaces, the bottom surface coupled to the first and second differential pads; a first mating differential pad and a second mating differential pad arranged as a pair and coupled to the top surface of the insulating layer, the first and second mating differential pads being aligned with the first and second differential pads, respectively; a circuit connected to the first and second differential pads and configured to provide differential signals based upon a first signal to the first and second differential pads, the circuit comprising an ohmic-type contact pad coupled to the first substrate and configured to receive a second signal representative of the first signal; and a mating ohmic-type contact pad in direct ohmic contact with the ohmic-type contact pad.
