Patent ID: 7692098

Claim:
A coaxial cable, comprising: a metallic inner conductor formed of a first material and having a first thickness; a dielectric layer circumferentially surrounding the inner conductor formed of a second material and having a second thickness; a metallic outer conductor circumferentially surrounding the dielectric layer formed of a third material and having a third thickness; and a polymeric jacket circumferentially surrounding the outer conductor formed of a fourth material and having a fourth thickness; wherein the first material, first thickness, second material, second thickness, third material, third thickness, fourth material and fourth thickness are selected so that the cable has: (a) a usable bandwidth between about 5 MHz and the cut-off frequency of the cable; (b) a minimum bend radius of less than about 5 times the jacket outer diameter; and (c) a velocity of propagation of greater than about 88; (d) a return loss of at least about −25 dB; and (e) a nominal impedance of 75 ohms.
