Cable assemblies can add unwanted passive intermodulation (PIM) to a system at various interfaces. Fortunately, a line of cable assemblies with snap-lock QMA connectors offers an alternative to traditional SMA coaxial connectors that can suffer from excessive levels of PIM. These cable assemblies are built with flexible, low-loss TFT-402-LF cables from Times Microwave. The cables are terminated with male QMA straight or right-angle connectors and meet UL910 fire requirements for in-building applications. The PIM levels are -140 dBc or better with standard QMA connectors and -155 dBc or better for premium straight QMA connectors. All of the low-PIM cable assemblies are tested, with measured results available on the firm’s online PIM Tracker function.
