New Methods for Identifying Sources of Outside PIM
|Mike Mikkelsen, Anritsu|
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. In this session, you will learn new methods for locating external PIM, how it works, and the PIM hunting process. Precise identification of external PIM sources are now possible!
