Abstract

The nonlinear characteristics of the passive devices will cause the nonlinear distortion of the system. Passive intermodulation is a typical nonlinear interference phenomenon. Coaxial connector as a widely used passive component will cause passive intermodulation, which is attributed to material nonlinearity and contact nonlinearity, and the environmental temperature will affect the contact characteristics and material characteristics of connectors. In this paper, considering the contact nonlinearity, the relation model between passive intermodulation performance and temperature was established theoretically, and the accuracy of the model was verified by a series of heating degradation experiments, and a real-time test system was designed to evaluate the passive intermodulation performance in the process of temperature cycle.
