Web8. júl 2001 · The passive intermodulation (PIM) phenomenon has been observed over the last four decades in various types of multi-frequency radio communication systems: shipboard antennas, ground stations and space borne antennas for satellite communications and, in wireless telecommunication systems. WebPIM stands for “passive intermodulation.” It represents the intermodulation products generated when two or more signals transit through a passive device with nonlinear properties. The interaction of mechanical …

Web1. nov 2002 · In this work, an analytical model for the study of passive intermodulation (PIM) on large reflector antennas is presented. Passive intermodulation, in the scattered field, … WebSince the power level of the PIM is generally very low, the components of the PIM test equipment should have high performance and low PIM characteristics. The residual intermodulation level generated by the synthesizer, directional coupler, filter, etc., shall be controlled below 10 dB of PIM level of the array antenna. grey goat shepherds huts
