A Mechanical Modelling and Simulation Method for Resolving PIM Problems in Antennas [PDF]

open access: yesSensors, 2021
Passive intermodulation (PIM) generated from antennas is a nonlinear distortion phenomenon and causes serious problems to communication quality. Traditional radio frequency (RF) solutions focus on testing the final product to find the PIM source. However,

Analysis of passive intermodulation in cascaded connectors with transmit‐receive systems

open access: yesIET Microwaves, Antennas & Propagation, 2023
Passive intermodulation (PIM) is usually expressed by the third‐order intermodulation power excited by two‐tone signal, which has limitations in characterising nonlinear distortion of signal in actual communication system.

Effect of second harmonic and second‐order intermodulation on third‐order passive intermodulation

open access: yesIET Microwaves, Antennas & Propagation, 2021
Third‐order intermodulation (IM3) is considered as a typical metric to evaluate passive intermodulation (PIM) in electrical connectors, which may be affected by the second‐order effect in the circuit with cascaded non‐linearities.

Passive Intermodulation at Contacts of Rough Conductors [PDF]

open access: yesElectronic Materials, 2022
Passive intermodulation (PIM) is a niggling phenomenon that debilitates the performance of modern communications and navigation systems. PIM products interfere with information signals and cause their nonlinear distortion.

Passive Intermodulation Measurement: Challenges and Solutions

open access: yesEngineering, 2022
In modern wireless communication systems, the signal-to-noise ratio (SNR) is one of the most important performance indicators. When the other radio frequency (RF) performance of the components is well designed, passive intermodulation (PIM) interference ...
