Research discovers heat is a major source of PIM.
Temperature and cross channel conduction, say researchers in the Hughes/London Southbank University collaborative research team, have critical effects on PIM. An influential White Paper due for general release by the team confirms the effect of temperature on metal connectors can add up to 10 DBC of PIM in the 3rd harmonic and that the phenomenon worsens through heat cycling (night/day conditions).
The discovery, along with other findings such as cross channel conduction and the importance of phase change and impedance has led to the incorporation of exciting PIM mitigation techniques in the radical composite configuration of the ‘WaveWay’ anti-PIM connecter series from Hughes Electronics.
