Behavioral Analysis of Non-Steady-State Passive Intermodulation

This study investigates the behavioral characteristics of non-steady-state PIM signals generated by smallarea multi-point contact PIM sources in radiated RF environments. Observations were conducted over millisecond-to-second intervals under both constant temperature and variable temperature scenarios to analyze PIM fluctuation dynamics. This study not only investigates the power variation in passive intermodulation but also conducts a comprehensive analysis of the power difference in PIM and its variation. Observations reveal that instability in PIM persists under constant temperature scenarios, alongside fluctuation patterns induced by temperature variations.
