ABSTRACT:
A coupling connector relies on inductive and capacitive coupling over a length L.sub.c to "connect" signals from a first circuit card to a second circuit card. The coupling connector includes a flex circuit which in a connected state is compressed to provide a coupling length L.sub.c between the first and second circuit cards. A typical application is for coupling cards to a backplane having a plurality of parallel, signal carrying tracks. The near end of each coupling track is input to a receiver having an input impedance equal to the characteristic impedance of the coupling track. The far end of the coupling track is terminated by a resistor whose value equals the characteristic impedance of the coupling track.
