IEC TR 61169-1-8:2025 provides a test method for voltage standing wave ratio (VSWR, hereinafter) of single RF connector by double-connector method. This document is applicable to single RF cable connectors and single microstrip RF connectors as well as single adapters if an estimation of the VSWR of a single completely installed RF-connector is used and a time domain feature is not available on the vector network analyzer.

Overview

IEC TR 61169-1-8:2025 is a Technical Report developed by the International Electrotechnical Commission (IEC), specifically by subcommittee 46F. This document defines a test method for determining the voltage standing wave ratio (VSWR) of a single radio-frequency (RF) connector using the double-connector method. Its scope includes single RF cable connectors, microstrip RF connectors, and RF connector adapters, particularly in scenarios where a time domain feature is not available on the vector network analyzer. This methodology supports manufacturers, test laboratories, and organizations working with RF components in achieving accurate VSWR measurements, ensuring optimal electrical performance and compliance with international standards.

Key Topics

VSWR Measurement: IEC TR 61169-1-8 outlines procedures for measuring the VSWR of isolated RF connectors, a critical parameter indicating impedance matching and signal reflection.

Double-Connector Method: The standard prescribes forming a test sample by connecting two identical connectors, determining the combined VSWR, and mathematically deriving the single connector's VSWR.

Applicability: The method is suitable for RF cable connectors, microstrip connectors, and adapter connectors, provided that estimation of the single connector's VSWR is needed without access to time domain analysis.

Sample Preparation: Detailed guidance is given on assembling test samples with low-attenuation, matched-impedance cables or interconnection pieces, typically using connectors from the same batch for product consistency.

Correction Factors: The document introduces correction coefficients for improving the accuracy of VSWR calculations, taking into account variations between otherwise identical connectors.

Test Procedures: Recommendations include appropriate measurement frequencies, cable lengths, and calculation methods, referencing IEC 61169-1-4 for core measurement technique alignment.

Applications

IEC TR 61169-1-8:2025 has broad applications across industries relying on RF technology, including:

Component Manufacturing: RF connector manufacturers employ these test methods for product development, quality assurance, and batch consistency verification.

Telecommunications: Accurate VSWR measurement of RF connectors is vital in maintaining the efficiency and signal integrity of telecom infrastructure.

Aerospace and Defense: Ensures high-reliability connections by verifying connector impedance properties, crucial in mission-critical RF communication systems.

Testing Laboratories: Provides an internationally recognized procedure for third-party validation of connector performance, streamlining product certification and compliance.

Research and Development: Supports engineers in designing and evaluating new connector types where impedance matching and minimal reflection are necessary for high-frequency circuit efficiency.

Field Installation and Maintenance: Offers a practical approach when time domain analysis tools are unavailable, enabling users to verify connector installation quality using standard frequency-domain equipment.

Related Standards

IEC TR 61169-1-8:2025 is part of the broader IEC 61169 series and references other key standards, including:

IEC 61169-1: Radio-frequency connectors - Part 1: Generic specification - General requirements and measuring methods, providing the general framework for RF connector testing.

IEC 61169-1-4: Radio-frequency connectors - Part 1-4: Electrical test methods - VSWR, return loss, and reflection coefficient, detailing specific test procedures complementing those in TR 61169-1-8.
