Overview
SIST EN 61169-32:2005/oprA1:2026 is a European standard developed by CLC, based on IEC 61169-32 and its Amendment 1. This standard focuses on radio-frequency (RF) coaxial connectors with an inner diameter of 1.85 mm (0.072 in) and screw coupling, designed for a characteristic impedance of 50 ohms (Type 1.85). The amendment introduces enhancements, including coverage extension for higher frequency ranges, enabling support for emerging technologies such as 5G wireless communications.
These specialized RF coaxial connectors are widely used in applications where precise impedance control and high-frequency performance are critical. The standard sets detailed technical requirements for electrical, mechanical, and environmental characteristics, ensuring consistent quality and interoperability.
Key Topics
Connector Type and Interface
- Describes RF coaxial connectors with a 1.85 mm outer conductor inner diameter and screw coupling mechanism.
- Provides compatibility for systems requiring a 50-ohm impedance, minimizing signal reflection and loss.
Frequency Spectrum Extension
- Amendment 1 increases the supported frequency range up to 71 GHz. This addresses new needs in telecommunications, particularly for 5G, that require operation above the previous 65 GHz upper limit.
- Improved reflection performance and lower insertion loss, especially for grades intended for high-frequency testing and measurement.
Grades of Connectors
- Addition of "Grade 0" connectors with enhanced electrical characteristics to meet demanding application environments, such as testing up to 71 GHz with minimal signal degradation.
Electrical and Mechanical Performance
- Specifies values for characteristic impedance, reflection factor, contact resistance, insulation resistance, and voltage proof.
- Defines requirements for mechanical strength, coupling force, vibration, shock resistance, and endurance under environmental stress.
Applications
5G Communication Systems:
- The expanded frequency range up to 71 GHz makes these connectors ideal for base stations, mobile devices, and test equipment operating in the high-frequency bands allocated to 5G NR (New Radio).
Test and Measurement Equipment:
- Precision connectors are essential for accurate signal transmission in vector network analyzers, spectrum analyzers, and other RF test systems where repeatable, high-frequency connections are required.
Microwave Devices and Circuits:
- Used extensively in microwave modules, radar, satellite communications, and other high-frequency electronic assemblies.
Laboratory and Research:
- Supports development and validation of emerging RF technologies up to the mmWave region.
