WebAug 3, 2024 · When it comes to PIM testing, the necessary steps to identify passive intermodulation (PIM) and locate its source are similar to interference hunting. In the … PIM is a form of intermodulation distortion that occurs in components normally thought of as linear, such as cables, connectors and antennas. However, when subject to the high RF powers found in cellular systems, these devices can generate intermodulation signals at –80 dBm or higher. Figure 1. See more The PIM test is a measure of system linearity while a Return Loss measurement is concerned with impedance changes. It is important to … See more Low PIM precision test cables are available commercially and they perform well, although they are very expensive. See more It is possible to have a PIM test pass while Return Loss fails, or PIM fail while Return Loss passes. Essentially, PIM testing will not find high Insertion Loss and Return Loss will not find high … See more When PIM products fall within the receive band of a cell site radio, they make the receiver less sensitive to weak signals that limits receive coverage. This increases the bit-error-rate (BER)and creates more dropped calls. If the … See more

WebA person experienced in interference hunting and PIM troubleshooting can sometimes recognize a PIM issue by its spectral signature, so to speak. A broad rise in the noise … WebAt a basic level, PIM is the result of unwanted signals created by mixing of two or more frequencies in a non-linear passive device. These new signals interfere with and distort the original signal passing between two wireless systems. It can create signal interference in any wireless system. To ensure reliable communications performance, PIM ...
WebPassive intermodulation (PIM) is a major source of noise in wireless networks, caused when downlink signals at a cell site mix at non-linear objects in the radiofrequency (RF) path. A common source is loose metal-to-metal contact or dissimilar metal contact in front of an antenna or inside the reactive near field behind an antenna.
