What is PIM?

Passive Intermodulation (PIM) is an increasing concern in the wireless community because of the affect it can have on the performance of the telecommunications network. PIM is generated whenever more than one frequency encounters a non-linear electrical junction or material. The resulting creation of undesired signals can result in decreased system capacity and/or degraded call quality. Reduced capacity and call quality at a cell site leads to reduced income for the wireless service providers. The economic loss is compounded when the affected customer becomes frustrated and switches over to a competing provider.

What causes PIM?

• Poor connections due to improper cable preparation, incorrect tools, or inexperience

• RF components fabricated with materials which exhibit some level of hysteresis (e.g., stainless steel)

• Contaminated surfaces or contacts within the RF path. Examples might include flux (which can attract other contaminants) and metallic particles from the machining process.
