Cable Construction & Specifications

Power, Attenuation & Phase Characteristics

To determine the maximum power rating of a cable assembly at ambient conditions, compare the average power rating of the cable against the connector average power rating (see page 31) and take the lowest value.

"Power handling is specified for conditions at sea level and +25 degree C. Use the de-rating chart (shown below) to estimate average or peak power levels at other altitude or temperature conditions."
