“…The contact nonlinearity of passive microwave devices is generally more serious than material nonlinearity in microwave communication systems. And it is caused by the nonlinear effects, such as the electron tunneling effect, the thermionic emission, micro-discharge, and electrostriction [3–5]. Yang [6] presented a measurement system based on the acoustic vibration to locate PIM sources in the base station antennas.…”

This paper investigates the generation of passive intermodulation (PIM) in coaxial connectors during vibration. A series of experiments were designed and the simulation model and method were proposed for understanding these phenomena. We found that PIM is mainly influenced by the contact stress and contact surface roughness during vibration. Thus, a power spectral density method is presented to identify the roughness parameter of contact surface based on the Weierstrass–Mandelbrot model, and the simulation model and method were verified by the relative experiments. Eventually, some suggestions for engineering application were provided.
