Understanding PIM
Passive Intermodulation (PIM) is becoming more and more significant as wireless users demand data, with high speeds. It affects network speed and performance, therefore, needs to be monitored, making PIM testing a requirement, especially today. Clinton Nevada has been producing Low PIM cables assemblies and providing Low PIM components for years.[/cs_text][/cs_column][/cs_row][cs_row inner_container=”true” marginless_columns=”false” class=”cs-ta-center” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/1″ style=”padding: 0px;”][x_image type=”none” src=”https://www.clintonnevada.com/wp-content/uploads/pim1.jpg” alt=”Low PIM Cables” link=”false” href=”#” title=”” target=”” info=”none” info_place=”top” info_trigger=”hover” info_content=””][/cs_column][/cs_row][cs_row inner_container=”true” marginless_columns=”false” class=”smallhead;” style=”margin: 0px auto;padding: 0px;”][cs_column fade=”false” fade_animation=”in” fade_animation_offset=”45px” fade_duration=”750″ type=”1/1″ class=”smallhead;” style=”padding: 0px;”][cs_text class=”cs-ta-left”]
What is PIM?
Passive Intermodulation occurs when two or more high power RF signals encounter non-linear electrical junctions or materials in an RF path. These non-linear junctions behave like a mixer causing new signals to be generated at mathematical combinations of the original RF inputs. When these PIM signals fall in the Rx band of the cell site the noise floor rises causing increased dropped calls, reduced data transmission rates and decreased system capacity. The impact of passive intermodulation on the network performance can be severe, especially for systems such as CDMA, UMTS or LTE. Causes of non-linear junctions include:
- Contaminated surfaces or contacts due to dirt, dust, moisture or oxidation.
- Loose mechanical junctions due to inadequate torque, poor alignment or poorly prepared contact surfaces.
- Loose mechanical junctions caused transportation shock or vibration
- Metal flakes or shavings inside RF connections.
- Poorly prepared RF connections
- Trapped dielectric materials (adhesives, foam, etc.)
- Cracks or distortions at the end of the outer conductor of coaxial cables caused by over tightening the back nut during installation
- Solid inner conductors distorted in the preparation process causing these to be out of round or tapered over the mating length.
- Hollow inner conductors excessively enlarged or made oval during the preparation process.
