Shielded cable assembly

An assembly configured to transmit electrical signals, comprising:

• a wire cable having
• a first inner conductor and second inner conductor;
• a shield surrounding the first inner conductor and the second inner conductor;
• and
• a dielectric structure configured to maintain a first predetermined spacing between the first inner conductor and the second inner conductor and a second predetermined spacing between said the first inner conductor and the second inner conductor and said shield, wherein the shield comprises
• an inner shield conductor at least partially enclosing the dielectric structure, thereby establishing a characteristic impedance of the wire cable,
• a ground conductor external to the inner shield conductor, extending generally parallel to the pair of first and second inner conductors and in electrical communication with the inner shield conductor, and
• an outer shield conductor at least partially enclosing the inner shield conductor and the ground conductor and in electrical communication with the inner shield conductor and the ground conductor.
