Abstract : Experimental power rating values for subminiature Polyfluoron, polyethylene and Teflon dielectric coaxial cables are presented for the frequency range of 1 to 10,000 megacycles. These are maximum ratings and depend upon the safe operating temperature of the particular cable dielectric material. Six subminiature coaxial cables (1 Polyfluoron, 2 polyethylene and 3 Teflon) were investigated with the cable diameters ranging from .080 inches to .155 inches and representing characteristic impedances of 50, 75, and 95 ohms. Techniques and special equipment necessary to adapt the experimental apparatus for making measurements on the subminiature coaxial cables are discussed. In addition, these basic maximum ratings are theoretically extended to an ambient temperature range of -85F (-65C) to 400F (205C) to altitudes from sea level to 70,000 feet and the effect of VSWR on the ratings are presented. The electrical and design characteristics of the associated Subminax R.F. connectors used with the various coaxial cables are discussed with a presentation of data on the standard Subminax connectors which were used in this investigation.
