Overview

SIST EN 60169-23:1998 is an important international standard published by the CLC that specifies the design and requirements for radio-frequency (RF) pin and socket connectors used with 3.5 mm rigid precision coaxial lines. These connectors feature an inner diameter of 3.5 mm on the outer conductor and are engineered to provide exceptional electrical performance, minimizing errors in test equipment attributable to the connector interface. The standard targets coaxial connectors that operate efficiently up to 34 GHz, supporting applications that demand high precision and low reflection characteristics. It establishes dimensional, mechanical, and electrical parameters to ensure optimal compatibility and performance.

Key Topics

• Precision Connectors: Defines two types of precision connectors - General Precision Connector (GPC) which is beaded, and Laboratory Precision Connector (LPC), which is beadless.
• Compatibility: Connectors are designed for 50-ohm rigid coaxial lines as specified in IEC 457-5 and can be mated with SMA connectors.
• Low Reflection Performance: Specifies low reflection coefficients suitable for microwave frequencies up to 34 GHz, with typical reflection factor expression provided to quantify connection quality.
• Dimensional Specifications: Provides detailed mating face dimensions in both metric and imperial units, ensuring standardization for manufacturing and interoperability.
• Contact Designs: Details plug and socket contact designs, including optional socket contact configurations that accommodate a range of pin sizes to maintain electrical integrity and connector longevity.
• Surface Finish: Specifies surface roughness requirements to optimize signal transmission and connector reliability.

Applications

SIST EN 60169-23:1998 connectors are critical components in high-frequency test and measurement equipment, telecommunications infrastructure, and precision RF systems, including:

• Microwave Test Apparatus: Minimizing measurement errors in vector network analyzers and spectrum analyzers.
• Laboratory Research: Providing highly reliable signal connections for laboratory-grade coaxial setups in academic and industrial research.
• Telecommunications Equipment: Ensuring signal integrity in microwave communication links and radar systems operating in the GHz frequency range.
• Instrumentation: Used in precision RF instrumentation requiring stable, repeatable interconnections with minimal signal degradation.
• Calibration Facilities: Serving as reference connectors for calibrating coaxial lines and equipment for high-frequency testing.

Related Standards

• IEC 60169-1: General requirements and measuring methods for radio-frequency connectors, which complements EN 60169-23 by outlining foundational practices.
• IEC 457-5: Rigid precision coaxial lines and associated precision connectors (50 ohms, 3.5 mm), establishing the coaxial line specifications that EN 60169-23 connectors interface with.
• EN 60169 Series: A comprehensive series covering various RF connector types and interfaces for diverse coaxial cable formats.
• SMA Connector Standards: Since EN 60169-23 connectors may be mated with SMA connectors, understanding SMA standards is relevant for interoperability.

Summary

SIST EN 60169-23:1998 sets the benchmark for pin and socket connectors designed for 3.5 mm rigid precision coaxial lines, ensuring standardized dimensions and electrical performance for RF applications up to 34 GHz. Its focus on low reflection, precise dimensional control, and compatibility makes it indispensable for manufacturers, test engineers, and system integrators working with microwave and millimeter-wave technologies. Adhering to this standard guarantees reliable, repeatable connections critical to the accuracy of high-frequency measurement and communication systems.

FOREWORD
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on
1)
which all the National Committees having a special interest therein are represented, express, as nearly as
possible, an international consensus of opinion on the subjects dealt with.
They have the form of recommendations for international use and they are accepted by the National
2)
Committees in that sense.
3) In order to promote international unification, the IEC expresses the wish that all National Committees
should adopt the text of the IEC recommendation for their national rules in so far as national conditions will
permit. Any divergence between the IEC recommendation and the corresponding national rules should, as
far as possible, be clearly indicated in the latter.
4) The IEC has not laid down any procedure concerning marking as an indication of approval and has no
responsibility when an item of equipment is declared to comply with one of its recommendations.
This standard has been prepared by Sub-Committee 46D: Connectors for r.f. cables, of
IEC Technical Committee No. 46: Cables, wires, waveguides, r.f. connectors, and access-
ories for communication and signalling.
The text of this standard is based on the following documents:
