face of the dielectric or within the interface itself will cause problems and may move directly within the connectors when installed. TECHNICAL CONSIDERATIONS FOR CHOOSING LOW PIM RF INTERCONNECTS Utilizing low PIM coaxial cable assemblies can help alleviate PIM effects. Various options are available depending on the type of 5G subsystem being designed. These include semi-rigid low PIM cables, low loss, low PIM corrugated copper cables
cable may be damaged if the maximum bend radius is exceeded.
This could create a kink, which would require the cable to be replaced. However, the damage may not be apparent until the system degrades and the troubleshooting process begins. New low PIM cable assemblies use a tinned, copper, flat-braid outer conductor construction to create an ultra- flexible cable with a durable FEP outer jacket to help alleviate this issue.
(which also come in a fire-retardant version), and helically corrugated designs that create a more flexible and rugged cable. On the other hand, installations within smaller internal packages with less physical space increasingly require coaxial cable assemblies that can accommodate tight bend radii. Unfortunately, flexibility does not typically go along with PIM performance, and a low PIM corrugated copper
Additionally, the connector is an integral component within the RF cable assembly. As cables get smaller, connectors need to do so as well. As a result, miniature connector configurations, including the NEX 10 or 1.0-2.3, are increasingly being used. These connector types are designed for low PIM performance and are available with a threaded coupling. Snap-on designs are emerging as well.
