IEC 61169-21:2022

IEC 61169-21:2022 defines the sectional specification for RF connectors with an inner diameter of outer conductor 9,5 mm (0,374 in) and screw coupling, with a characteristic impedance of 50 ohms (Type SC). It is relevant when engineers, buyers, and compliance teams need a technical reference for selecting, documenting, or evaluating connector interfaces in RF assemblies. IEC 61169-21:2022 helps align product assessment, procurement review, and verification activities around a clearly defined connector family.

IEC 61169-21:2022 standard overview

This document serves as the primary technical reference for the Type SC RF connector interface described in the official title. It is generally used to support engineering documentation, dimensional and interface review, and conformity assessment for 50 ohm RF connector applications. The sectional specification format indicates a focused scope: it is intended to define the connector family in a way that supports consistent design interpretation, testing workflows, and technical validation across suppliers and internal quality processes.

Applications of IEC 61169-21:2022

IEC 61169-21:2022 is commonly relevant in RF hardware procurement, connector qualification, and laboratory evaluation where screw-coupled 50 ohm interfaces must be identified and handled consistently. It may be used in engineering specification packages, incoming inspection criteria, and product evaluation workflows for cable assemblies, test fixtures, and related RF equipment. Organizations working on compliance preparation or controlled manufacturing documentation can use it as a reference point for technical review and operational consistency.

Why IEC 61169-21:2022 matters

Using a defined reference such as IEC 61169-21:2022 supports clearer communication between design, testing, and procurement teams. It can reduce risk by improving interface compatibility expectations and by giving laboratories a consistent basis for verification activities. For organizations involved in conformity assessment or quality assurance, the specification helps structure technical assessment and documentation review around a known connector type, which can improve repeatability and reduce ambiguity during product validation.
