Overview
IEC 61169-65:2021 is an international standard published by the International Electrotechnical Commission (IEC) that outlines the sectional specification for RF coaxial connectors with a 1.35 mm inner diameter of the outer conductor. These connectors feature screw-coupling and have a characteristic impedance of 50 Ω, designed primarily for high-frequency applications up to 90 GHz. This standard addresses the preparation of detailed specifications (DS) for this series of connectors, focusing on test and measurement applications where precision and reliability are essential.
The standard provides comprehensive technical requirements including dimensions, mechanical interface specifics, gauging information, and quality assessment procedures tailored for both general-purpose and test-grade connectors. IEC 61169-65 complements the generic specifications outlined in IEC 61169-1 and supports performance characterization necessary for high-frequency radio-frequency (RF) connector technologies.
Key Topics
-
Connector Dimensions and Types
Specifies precise mating face dimensions for general-purpose connectors (grade 1) and standard test connectors (grade 0) with pin and socket centre contacts. These dimensional details are critical to ensure interchangeability and consistent performance in test setups and RF systems.
-
Screw-Coupling Mechanism
Defines the screw coupling thread (M5.5 x 0.5) and mechanical interface requirements that guarantee robust, vibration-resistant connections vital in high-frequency measurement environments.
-
Quality Assessment and Testing
Includes recommended performance characteristics and test procedures covering acceptance and periodic tests relevant for quality levels M and H. Tests are selected from IEC 61169-1 and specify inspection protocols, ensuring reliable connector performance up to 90 GHz.
-
Gauge and Inspection Provisions
