IEC 61169-54:2016 PDF

Overview

IEC 61169-54:2016 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies sectional requirements for coaxial radio frequency connectors with a 10 mm inner diameter of the outer conductor and a nominal characteristic impedance of 50 Ohms. This standard pertains to the Series 4.3-10 connectors, which feature screw type, hand screw type, or quick-lock type coupling mechanisms. The specification targets connectors suitable for upper operating frequencies up to 6 GHz, commonly used in wireless telecommunication and wireless network applications.

The document serves as a sectional specification guiding the development of detail specifications (DS) tailored to 4.3-10 series connectors. It covers physical dimensions, mating interface configurations, quality assessment procedures, test schedules, and inspection requirements necessary to ensure connector performance and reliability.

Key Topics

• Connector Dimensions and Mating Interface: IEC 61169-54 defines precise mechanical dimensions for connectors with pin-centre and socket-centre contacts, including gauge pins and rings for verification. These details facilitate interoperability and ensure consistent performance across various manufacturers.

• Coupling Mechanisms: The standard outlines three common coupling types for the 4.3-10 series connectors:

  • Screw type
  • Hand screw type
  • Quick-lock type These allow flexibility in installation and maintenance while maintaining reliable contact integrity.

• Impedance and Frequency Ratings: The nominal characteristic impedance is fixed at 50 Ohms, with operational frequency limits up to 6 GHz, making these connectors ideal for modern wireless communication systems requiring low signal loss and reflection.

• Quality Assessment and Testing: The standard references test categories and procedures from IEC 61169-1, specifying acceptance and periodic test schedules to assess mechanical, electrical, and environmental performance. It includes methods for quality conformance inspection under assessment levels M and H, covering climatic categories, mechanical endurance, and electrical continuity.

• Marking and Packaging: Clear guidelines on marking connectors and packaging contents ensure traceability and compliance with international practices.

Applications

IEC 61169-54 connectors are widely applied in:

• Wireless Telecommunication Networks: Ensuring secure and efficient RF signal transmission lines in cellular base stations and antenna systems.

• Wireless Broadband Access: Facilitating high-frequency signal integrity for internet service providers and network infrastructure.

• Broadcasting and RF Test Equipment: Offering reliable mating connections with minimal signal reflection for measurement and monitoring devices.

• Industrial and Military Radios: Meeting stringent environmental and mechanical requirements in harsh and demanding conditions.

Their combination of robust design, reliable coupling mechanisms, and standardized dimensions enhances installation efficiency and system reliability in critical communication infrastructures.
