SIST EN 61169-32:2005

Overview

SIST EN 61169-32:2005 specifies the requirements and characteristics for type 1.85 RF coaxial connectors featuring a screw coupling mechanism and an inner diameter of the outer conductor of 1.85 mm (0.072 in). These connectors are designed for a nominal characteristic impedance of 50 ohms and support operation at frequencies up to 65 GHz. The standard is published by the CLC (European Committee for Electrotechnical Standardization) and is harmonized with IEC 61169-32.

Key Topics

• Connector Design: Detailed specifications for type 1.85 RF coaxial connectors, which enable secure screw coupling to ensure robust mechanical and electrical performance.
• Frequency Range: Designed for high-frequency applications, supporting operation up to 65 GHz, making them suitable for demanding microwave and RF environments.
• Cable Compatibility: The connectors are recommended for use with both semi-rigid and flexible cables, providing flexibility in integration with different transmission media.
• Performance Requirements: The standard covers essential performance aspects, such as impedance consistency, insertion loss, return loss, and connector durability.
• Testing and Quality Assurance: Specifies testing methods and acceptance criteria to guarantee reliable connector performance in high-frequency data transmission applications.
