IEC 61169-53:2015

Overview

IEC 61169-53:2015 is an international standard published by the International Electrotechnical Commission (IEC) that specifies requirements for radio-frequency (RF) coaxial connectors with a 16 mm inner diameter outer conductor, featuring screw lock mechanisms and a characteristic impedance of 50 Ohms. Known by the designation Type S7-16, these connectors are primarily utilized in 50 Ohm cable networks for high-performance RF and microwave transmission systems. This sectional specification provides detailed guidance for the preparation of detail specifications (DS), encompassing dimensional, performance, and testing parameters for these RF coaxial connectors.

Key Topics

• Connector Designation: Specifies Type S7-16 RF coaxial connectors with a 16 mm inner diameter of the outer conductor and threaded coupling for secure connections.
• Characteristic Impedance: Standardized at 50 Ω, suitable for most professional RF and microwave applications.
• Applications: Intended for connection with RF cables and microstrips within microwave transmission systems.
• Performance Criteria: Includes requirements for mating face dimensions, electrical and mechanical properties, and climate resistance.
• Quality Assessment: Outlines comprehensive test schedules and inspection requirements for quality assurance at different assessment levels.
• Detail Specification Guidance: Provides standardized templates and rules for creating detail specifications applicable to variations within the S7-16 connector family.
• Testing References: Incorporates references to IEC 61169-1 (generic requirements) and IEC 62037 (intermodulation measurement).

Applications

The IEC 61169-53:2015 standard supports a wide range of practical uses in telecommunications and RF engineering:

• High-frequency Cable Networks: Used for connecting cables, antennas, and devices in professional wireless, cellular, and broadcast infrastructures.
