OG exemplary drawing
 
1. A shielded electrical ribbon cable, comprising:
a plurality of conductor sets extending lengthwise along the cable and arranged generally in a plane along a width of the cable, at least 90% of a periphery of each conductor set surrounded by and fixably coupled to an electrically conductive shield, each conductor set including two insulated conductors and a ground conductor generally lying in a plane of the two insulated conductors; and
a polymeric material covering opposite sides of the cable and encompassing at least 75% of a periphery of each conductor set, wherein,
the plurality of conductor sets comprises adjacent first and second conductor sets, the first conductor set having a high frequency isolation between the two insulated conductors characterized by a crosstalk C1 at a specified frequency in a range from 3 to 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, wherein C2 is at least 10 dB lower than C1, and wherein, the cable has a skew of less than 20 psec/meter.
