IEC 61169-48:2014

Overview

IEC 61169-48:2014 is an international standard issued by the International Electrotechnical Commission (IEC) that defines sectional specifications for series BMP radio-frequency (RF) coaxial connectors. These connectors feature blind mating capabilities and are primarily intended for 50 Ohms board-to-board connections. The standard outlines the dimensional, electrical, mechanical, and testing requirements that manufacturers and designers must follow to ensure compatibility and reliability. This standard supports applications in microwave systems, telecommunication, wireless communications, and other RF fields, with operating frequencies up to 6 GHz.

The specification provides guidance for preparing detailed specifications (DS) for BMP connectors, covering interface dimensions, gauging information, performance criteria, mandatory tests, and inspection requirements according to IEC 61169-1:2013 general requirements for RF connectors.

Key Topics

• Connector Interface Dimensions
  Precise dimensions for connectors with pin-center contacts and socket-center contacts are detailed, including the use of gauging tools for quality assurance and compliance checks.

• Blind Mating Capability
  Description of design features allowing connectors to be easily mated without visual alignment, enhancing installation efficiency in compact and complex assemblies.

• Electrical and Mechanical Performance
  Parameters such as impedance matching, contact retention, mechanical durability, and maximum permissible deflection and axial clearance when mounted on printed circuit boards (PCBs).

• Testing and Quality Assessment
  Sets forth mandatory and periodic tests-including electrical, mechanical, and climatic tests-ensuring consistent performance. The standard outlines acceptance test schedules and quality conformance procedures to maintain manufacturing standards.

• Preparation of Detailed Specifications (DS)
  Instructions on writing detail specifications include component identification, performance criteria, marking requirements, and selection of relevant tests to suit specific application needs.

Applications

IEC 61169-48:2014 BMP RF coaxial connectors are widely used in:

• Telecommunication Equipment
  Ensuring reliable and standardized board-to-board RF connections in communication devices operating in the GHz frequency range.
