Passive Intermodulation Distortion (PIM) is a phenomenon that occurs when 2 signals present on a transmission line mix in a non-linear manner. This mixing creates additional frequency components (where the fim = ± mf1 + ±nf2 and m and n are integers) that may fall within a cellular uplink band, causing interference. Poorly designed or assembled connectors and cable assemblies can generate PIM. Amphenol RF has a complete line of low PIM connectors and cable assemblies.
