Claim:
1. A shielded electrical cable, comprising: a plurality of conductor sets extending along a length of the cable and arranged generally in a plane along a width of the cable, at least 90% of a periphery of each conductor set being encompassed by a shielding film each conductor set including two insulated conductors; first and second non-conductive polymeric layers disposed on opposite sides of the cable, the first and second layers including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second polymeric layers in combination substantially surround the plurality of conductor sets, and the pinched portions of the first and second polymeric layers in combination form pinched portions of the cable on each side of the cable; and an adhesive layer bonding the first non-conductive polymeric layer to the second non-conductive polymeric layer in the pinched portions of the cable; wherein: a maximum separation between the cover portions of the first and second polymeric layers is D; a minimum separation between the pinched portions of the first and second polymeric layers on each side of the cable is d a minimum separation between the cover portions of the first and second layers in a region between the conductors of each conductor set is d wherein the plurality of conductor sets comprises adjacent first and second conductor sets, the first conductor set having a high frequency isolation between the adjacent insulated conductors characterized by a crosstalk C1 at a specified frequency in a range from 3-15 GHz and for a 1 meter cable length, wherein a high frequency isolation between the first and second conductor sets is characterized by a crosstalk C2 at the specified frequency, and wherein C2 is at least 10 dB lower than C1.
