This document is a cable specification chart that provides technical specifications for various coaxial cables including their construction details, impedance ratings, frequency ranges, and insertion loss measurements. It lists over 30 different cable types ranging from flexible to semi-rigid designs with varying center conductor sizes and dielectric materials. For each cable, the chart specifies properties such as outer diameter, impedance, jacket material, center conductor material and configuration, dielectric, manufacturer and part number. It also provides suggested maximum frequency ranges and insertion loss data across a range of frequencies from 500MHz to 40GHz.
