The new ConcealFab PIM Test Probe will help solve RF equipment and PIM needs by pinpointing errors in analysis and helping sites meet expectations. Passive intermodulation (PIM) is a well-known problem in cellular systems. Downlink signals at the cell site mix at passive, non-linear junctions in the RF path, creating new signals. If these new signals (intermodulation products) fall in an operator’s uplink band, they can elevate the noise floor and degrade system performance.
RF equipment manufacturers have spent decades developing methods to improve the PIM performance of the RF components deployed at cell sites. In addition, the crews installing these components have fine-tuned their skills to the point that PIM levels below -150 dBc (with 20W test tones) is now readily achievable within antenna feed systems. Unfortunately, a low PIM feed system by itself doesn’t ensure that a site will perform to expectations. PIM sources beyond the antenna are now often the limiting factor for site PIM performance.
