PIM Requirements for Low Power Wireless Components and Subsystems

Posted November 20, 2013

Low PIM Requirements

Passive intermodulation, PIM, continues to be a concern for high speed Wireless networks. A good understanding of how it impacts the network operation and how to detect and avoid it has been rapidly developing. This has reflected in PIM testing procedures and limits for high power RF components and subsystems. As these specifications were mostly geared towards high power, +40 W applications and components, there is a need to address the low power PIM requirements as such systems are playing a bigger role in new roll outs. We attempt to define here those reasonable limits.

Microlab Offers New Low Loss 4x2 Hybrid Diplexer for Low PIM Head End DAS Applications

Posted October 22, 2013

WTG is adding a new Hybrid Diplexer to its popular Hybrid Combiner Product Line. Microlab Hybrid Combiners are known for their low PIM, low loss, and high isolation which make them ideal for efficiently combining RF signals particularly in active and passive DAS deployments.

Wireless Telecom Group offers new line of Low PIM components for DAS applications

DCC Series

Microlab is introducing a new product line for both in-Building and outdoor DAS applications, the DCC Series™ DAS Carrier Conditioners.  These products are equally suited for passive DAS venues and for active fiber DAS installations. DCC Series™ DAS interfaces allow for a wide variety of configurations, starting from simple two-port combining, to multi-carrier multi-band systems with integrated low pim, high power attenuators plus variable attenuators and monitoring ports.

Webinar - Are Passive Intermodulation (PIM) Effects of Concern for In-Building DAS Venues?

Posted November 5, 2012

PIM signals residing in the receiving bands of telecommunication systems interfere with actual Rx signals and with that, reduce the network's capacity. The amount of unwanted PIM signals is directly proportional to the carrier power in the RF path. While macro cells operate at high power levels, most in-building DAS networks use low antenna power levels because they employ multiple antennas. Compared to macro cells, each antenna needs to cover only a relatively small area.  Does ubiquitous system noise supersede any PIM effects? Wolfgang Damm discusses causes of Passive Intermodulation (PIM), its effects on network quality and offers guidelines to ensure networks provide maximum bandwidth.
