Abstract
Official abstract text for this publication.
A shielded electrical cable includes one or more conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable. Each conductor set has one or more conductors having a size no greater than 24 AWG and each conductor set has an insertion loss of less than about −20 dB/meter over a frequency range of 0 to 20 GHz. First and second shielding films are disposed on opposite sides of the cable, the first and second films including cover portions and pinched portions arranged such that, in transverse cross section, the cover portions of the first and second films in combination substantially surround each conductor set, and the pinched portions of the first and second films in combination form pinched portions of the cable on each side of each conductor.
First claim
Opening claim text (preview).
What is claimed is: 1. A shielded electrical cable, comprising: a plurality of conductor sets extending along a length of the cable and being spaced apart from each other along a width of the cable, each conductor set having two conductors arranged in a twinaxial configuration, each of the conductors having a size no greater than 24 AWG; and first and second shielding films disposed on opposite sides of the cable, neither shielding film comprising a longitudinal fold that orients the shielding film to cover the conductor sets on both sides of the cable, wherein the insertion loss of each conductor set is less than about −5 dB per meter or less than about −4 dB per meter, or less than about −3 dB per meter.
