Passive intermodulation distortion (PIM), is a prevalent issue with cellular networks and other wireless systems with relatively high broadcast power and dense channel plans. The results of PIM can be the desensitization of the receiver, dropped calls, and harmonic interference that can affect receivers for other frequency bands and services well outside of the carrier ..

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 ..

There are many coaxial connectors used in wireless and wired networks, including DIN 7/16, N, 4.1/9.5, and the 4.3-10 interface. Typically, the choice of a connector boils down to economics, power handling, size, and installation criteria. However, the increasing number of wireless network bands and mobile data rates pose a very stringent requirement for transmission ..

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. ..
