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, ..

Passive intermodulation distortion (PIM) is phenomenon that degrades communication system performance in virtually all DAS and cellular installations. The severity of PIM, and the measures necessary to mitigate PIM depend on the system design, materials, environment, transmit power, and the systems sensitivity to PIM. Single frequency and narrow band communications technologies tend to be less ..

With the growing number of distributed antenna system (DAS) and small cell installations, low passive-intermodulation distortion (PIM) interconnect and components have gained popularity. Modern complex multi-carrier communication systems, such as DAS and small cells, are now incredibly wide-band and support a plethora of wireless standards, such as WiFi, cellular, military, government, public safety, and emergency ..

Testing interconnect for upper microwave and millimeter-wave frequencies is intrinsically a challenge. The small geometries and extremely tight tolerances on geometries, conductor surfaces, and closely located differential signal traces place additional design burdens and create testing obstacles for high-speed data and telecommunications applications. One of the major considerations to address is how to add test ..
