A shielded electrical ribbon cable includes adjacent first and second longitudinal conductor sets where each conductor set includes two or more insulated conductors. The first conductor set also includes a ground conductor that generally lies in the plane of the insulated conductors of the first conductor set. At least 90% of the periphery of each conductor set is encompassed by a shielding film. First and second non-conductive polymeric films are disposed on opposite sides of the cable and form cover portions substantially surrounding each conductor set, and pinched portions on each side of each conductor set. When the cable is laid flat, the distance between the center of the ground conductor of the first conductor set and the center of the nearest insulated conductor of the second conductor set is σ1, the center-to-center spacing of the insulated conductors of the second conductor set is σ2, and σ1/σ2 is greater than 0.7. 1.

A shielded electrical cable includes conductor sets extending along a length of the cable and spaced apart from each other along a width of the cable. First and second shielding films are disposed on opposite sides of the cable and include cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the films in combination substantially surround each conductor set. An adhesive layer bonds the shielding films together in the pinched portions of the cable. A transverse bending of the cable at a cable location of no more than 180 degrees over an inner radius of at most 2 mm causes a cable impedance of the selected insulated conductor proximate the cable location to vary by no more than 2 percent from an initial cable impedance measured at the cable location in an unbent configuration. 1. A shielded electrical cable , comprising:a plurality of differential pairs extending along a length of the cable and arranged generally in a plane along a width of the cable, each differential pair including two insulated conductors having wire diameters not greater than 24 American Wire Gauge (AWG), at least 90% of a periphery of each differential pair encompassed by, and bonded to, a shielding film such that for a frequency range from about 2 GHz to about 20 GHz, a far end cross talk (FEXT) between adjacent differential pairs is less than about −35 dB;a non-conductive polymeric layer covering opposite sides of the plurality of differential pairs and substantially surrounding each differential pair;wherein a transverse bending of the cable at a cable location of 90 degrees over an inner radius of at most 5 mm causes an insertion loss of the insulated conductors of the differential pairs proximate the cable location to vary by no more than about 0.5 dB from an initial insertion loss measured at the cable location in an unbent configuration;wherein a high frequency electrical isolation of a first insulated conductor of a first differential ...
