Abstract: 

The performance of radio frequency (RF) cable, the main physical carrier of signal transmission, is affected by multiple factors. This paper sets up a 3D finite-element model of the RF cable to study the signal attenuation features of such single factors as insulating layer thickness, signal frequency and ambient temperature. Then, the insertion loss and variance analysis of nine parameters of the RF cable were discussed in orthogonal design. The results show that the signal attenuation is positively correlated with signal frequency and ambient temperature, but negatively correlated with the insulating layer thickness; in terms of the effect on insertion loss, the parameters are ranked as signal frequency>insulating layer thickness>ambient temperature in descending order. Next, the author obtained the signal features and proposed a multivariate regression model. The experimental results show that the model has an error of less than 3%, an evidence of high accuracy.
