IEC 61169-16:2006

Overview

IEC 61169-16:2006 is the IEC sectional specification for RF coaxial connectors (type N) with an outer-conductor inner diameter of 7 mm (0.276 in) and a screw coupling. It defines rules and guidance for preparing Detail Specifications (DS) for pin and socket connectors used in low-to-medium power RF applications. The document covers the 50 Ω family (with a deprecated 75 Ω variant provided for guidance) and specifies interface dimensions, grades, performance expectations and test/inspection requirements.

Key topics and technical requirements

• Connector types and designation
  • Type N, 50 Ω (75 Ω guidance) - example designation: 61169-16 IEC-50-G0 (standard test connector).
  • Three grades: Grade 0 (standard test), Grade 1 (high performance), Grade 2 (general purpose); all three 50 Ω versions are mateable.
• Interface dimensions
  • Inch-based primary dimensions; metric equivalents provided as acceptable alternatives.
  • Key mechanical details include centre contact forms (pin and socket), mating threads (e.g. 5/8‑24 UNEF‑2B referenced), gauge limits and tolerances.
• Electrical / frequency guidance
  • Grade 2 (general purpose) suitable with IEC 60096-2 cable up to ~12 GHz.
  • Grade 1 (high performance) and Grade 0 (standard test) intended for lower reflection and precision use - some Grade 1/0 devices may be used up to 18 GHz.
• Quality assessment and testing
  • Ratings and characteristics, test schedules, inspection criteria and periodic/acceptance tests are defined to support DS preparation.
  • Mechanical gauges, standard test connectors and detailed test connector drawings are provided as references.
• 75 Ω note
  • 75 Ω Type N is strongly deprecated; accidental mating with 50 Ω can cause damage - clear identification recommended.

Applications and users

• Who uses this standard:
  • Connector manufacturers preparing detail specifications and production drawings.
  • RF / microwave test laboratories and calibration facilities using Grade 0 standard test connectors.
  • OEMs and system integrators specifying reliable RF interfaces for equipment, cable assemblies and components.
  • Procurement, quality and compliance engineers ensuring interchangeability and testability.
• Typical applications:
  • RF test benches, coaxial cable assemblies, microwave components and equipment where Type N interfaces are required for up to 12–18 GHz depending on grade.
