Passive Intermodulation (PIM) is a growing concern among mobile network operators looking for maximizing their network's capacity, data rate, reliability and Return on Investment (ROI) with the deployment of 5G wireless networks. But what is exactly PIM? When two or more frequencies are mixed in a non-linear way in a passive circuit, an interference is generated and is known as PIM. The performance of a network can be adversely affected if the interference collides with uplink receive frequencies of an LTE or 5G network, generating -100dBm or higher intermodulation signals. Lowering the level of PIM, operators can achieve better capacity and network coverage.
