RF Power in a Coaxial Cable Assembly

One of the most often asked questions from our customers about our cable assemblies is “how much power can this cable assembly handle”. My response is usually the same, “it depends”. This question cannot be understood in its completeness without the understanding of power, and the many variables that contribute to the makeup of power transmission. This white paper will serve to shed some light on this issue, and at the same time, give some practical examples seen in the industry. In addition, hopefully, it will explain why it is difficult to just give a chart or table for all of our cable assemblies with regard to power handling.
