Understanding the RF power in a coaxial cable assembly

14 December 2021

How much power can your cables handle?

One of the most often asked questions from our customers about our cable assemblies is “How much power can this cable assembly handle?”. 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.

In Smiths Interconnect's white paper RF Power in a Coaxial Cable Assembly, Principal RF Design Engineer Glenn Tilton will shed some light on this issue, and at the same time, give some practical examples seen in the industry. In addition, it will explain why it is difficult to just give a chart or table for all our cable assemblies with regard to power handling.

Discussion Points:

  • Why we need RF power transmission?
  • Peak Power verse Average Power
  • The variables that effect power in cable assemblies including:
    • Frequency
    • VSWR/Return Loss
    • Altitude
    • Temperature
