摘要： Improved flat flexible cable having at least one shielded transmission line is disclosed. The subject cable is formed with either a single or a plurality of signal conductors on one side of a flat flexible insulator substrate and one or a plurality of ground conductors on the opposite side of the substrate, the ground conductors preferably being interconnected. Pads are formed at periodically spaced intervals along each of the signal and ground conductors so that the cable can be produced with infinite length and cut to finite lengths at the pads nearest the desired length while maintaining constant electrical transmission properties (such as characteristic impedance, cross-talk, attenuation, etc.) throughout the length of the line and including the termination area.
