White Paper: Passive Intermodulation Distortion
The document "Passive Intermodulation Distortion in Connectors, Cable and Cable Assemblies" by David Weinstein of Amphenol Corporation discusses the causes, impacts, and measurement of Passive Intermodulation Distortion (PIM) in RF components. It explains how PIM is generated by non-linear mixing in passive devices like connectors and cables, causing unwanted signals that can interfere with communication systems. The paper outlines design guidelines to minimize PIM, including contact design, material choices and cleanliness, and describes testing methods to ensure low PIM performance.
