Passive RF and microwave devices, intermodulation level measurement - Part 2: Measurement of passive intermodulation in coaxial cable assemblies (IEC 62037-2:2021)

This part of IEC 62037 defines a procedure to measure levels of passive intermodulation generated by a coaxial cable assembly.
This test method is applicable to jumper cables, i.e. cable assemblies intended to provide interface flexibility between rigid devices. It is also used to evaluate cable assemblies that are subjected to motion in operation.

IEC 62037-2:2021 définit une procédure pour la mesure des niveaux d’intermodulation passive générés par un cordon coaxial. Cette méthode d’essai s’applique aux jarretières, c’est-à-dire aux cordons destinés à fournir une interface flexible entre des dispositifs rigides. Elle est également utilisée pour évaluer des cordons soumis à des mouvements pendant leur fonctionnement. Cette seconde édition annule et remplace la première édition parue en 2012. Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition précédente:

Overview

SIST EN IEC 62037-2:2022 specifies a standardized procedure for measuring passive intermodulation (PIM) levels generated by coaxial cable assemblies. This standard is essential for evaluating the performance of cable assemblies, particularly jumper cables, that link rigid RF and microwave devices or are subjected to movement during operation. The methodology ensures consistent PIM testing, which is critical for maintaining signal integrity and preventing performance degradation in RF and microwave communication systems.

By following IEC 62037-2, manufacturers, engineers, and testing laboratories can reliably assess PIM in coaxial cable assemblies, supporting compliance with international requirements in industries such as telecommunications, broadcasting, and wireless network infrastructure.

Key Topics

• Passive Intermodulation (PIM) Measurement: Defines the step-by-step procedure to detect and quantify PIM levels produced by cable assemblies.
• Test Method for Jumper Cables: Specific focus on cable assemblies that provide flexible links between otherwise rigid components, such as in base stations or repeaters.
• Mechanical Stress Simulation: Includes test conditions mimicking operational motion and rotation to evaluate the PIM response under realistic scenarios.
• Calibration and Reporting: Outlines calibration procedures and documentation requirements for accurate and repeatable results.
• Setup Requirements: Describes necessary set-up, including connectors, cable support, and mechanical stress parameters relevant to the cable’s diameter and bending radius.

Applications

SIST EN IEC 62037-2:2022 is widely used in areas where high-frequency performance and low intermodulation are crucial:

• Telecommunications: Validates the quality of coaxial jumper cables within cellular base stations and distributed antenna systems, contributing to improved system reliability and reduced interference.
• Broadcasting: Ensures clear signal transmission and prevents PIM-related signal degradation in radio and television networks.
• Wireless Infrastructure: Applied during manufacturing and installation to guarantee that cable assemblies meet stringent RF performance criteria.
• Equipment Testing and Certification: Used by test laboratories to certify coaxial cable assemblies prior to deployment in mission-critical RF applications.
• Quality Assurance: Supports ongoing maintenance and inspection routines for installed cable assemblies exposed to mechanical stress or movement.

Related Standards

To provide comprehensive guidance, SIST EN IEC 62037-2:2022 references several related standards within the IEC 62037 series:

• IEC 62037-1: General requirements and measuring methods for passive RF and microwave devices, forming the foundation for all PIM testing methodologies.
• IEC 62037-3: Procedures specific to measuring passive intermodulation in coaxial connectors, complementing the cable assembly focus of Part 2.
• IEC 62037-4: Focuses on PIM measurement in coaxial cables themselves, ensuring overall integrity of the entire RF path.
• ICS 33.120.10: Coaxial cables and waveguides - classification supporting proper product identification and application.
• ICS 33.120.30: RF connectors - for comprehensive coverage of all passive components involved in RF signal transmission.
