When DAS Meets PIM: On the Challenges of Accounting for PIM with Distributed Antenna Installations (Part 1)

Posted on By

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…
