Microwave Power Dividers (splitters) are a subset of RF power dividers and RF power tappers, which are a common component in many RF/microwave circuits and systems. The main purpose of a RF splitter for microwave or RF applications is to split the power incident at the input port to a number of output ports. The ..

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 ..

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 ..

Passive intermodulation (PIM) distortion is a wireless communication system degrading phenomenon that has been a concern for cellular telecommunications, satellite communications, and wireless network development. PIM is such a concern in cellular/wireless communications that there are entire distinct Low PIM Components and Cable Assemblies product lines designed to aid in preventing or mitigating PIM distortion. ..
