As there is an increasingly diverse range of wireless, RF, high-speed data, research, and sensing applications that involve the transmission, reception, and manipulation of RF signals, there is also a growing diversity of coaxial cable assemblies. One of the most significant uses of coaxial cable assemblies are in test and measurement and within high precision ..

In last week’s post, we covered foundational details regarding PIM in modern wide-band and multi-carrier communication systems, with a note on upcoming 5G NR sub-6 GHz frequencies being added to the mix. This week’s blog expands upon that discussion and provides more details of PIM considerations specific to DAS. With DAS, another large PIM concern ..

Passive intermodulation distortion is the result of discontinuities, metal-to-metal contact, and material properties that lead to nonlinear characteristics of typically linear passive transmission lines and components. PIM can be induced in a variety of RF components, such as connectors, adapters, cable, combiners, splitters, couplers, tappers, attenuators, terminators, antennas, and cable-to-board interconnect. PIM is generated when ..

Last week’s post covered why low PIM components, other than coaxial cables and assemblies, can be important to consider for low PIM applications. This blog focuses on low PIM Directional Couplers, Loads, Attenuators, Adapters, and Antennas, and provides brief descriptions of their use cases and value. Low PIM Directional Couplers Unlike tappers, splitters, and dividers, ..

Low PIM Cable Assemblies Utilizing a Hand Formable Semi-Rigid Coax Debuted Pasternack’s low PIM hand formable cable jumpers are made using a tin-filled braid that produces a hand-formable, solid outer conductor wall, making them perfect for installation into tight places. These low passive intermodulation (PIM) cable assemblies are available with two different coax diameters sizes ..
