Radio-frequency connectors - Part 64: Sectional specification - RF coaxial connectors with 0,8 mm inner diameter of outer conductor - Characteristic impedance 50 Ω (type 0,8) EN IEC 61169-64:2025

Publication date:   Jan 15, 2026

Scope

IEC 61169-64:2025, which is a sectional specification (SS), provides information for the preparation of detail specifications (DS) for coaxial connectors with 0,8 mm inner diameter of the outer conductor, characteristic impedance of 50 Ω, and with screw coupling. These connectors are referred to below as type 0,8 connectors. They are used in telecommunications technology as well as in test and measurement applications for operating frequencies up to 145 GHz.

This document describes mating face dimensions for high performance connectors (grade 1) and standard test connectors (grade 0), gauging information and tests selected from IEC 61169-1, applicable to all detail specifications relating to type 0,8 connectors.

This document indicates the recommended performance characteristics to consider when writing a detail specification and it covers test schedules and inspection requirements for assessment levels M and H.

This second edition cancels and replaces the first edition published in 2019. This edition constitutes a technical revision.

This edition includes the following significant technical changes with respect to the previous edition:

a) upgrading of the inferior connector class to a grade 1 “high performance connector”;

b) alignment of the mating face dimensions as well as the ratings and characteristics with the precision 0,8 mm connectors specified in the IEEE 287.1-2021 and IEEE 287.3-2021 standards;

c) figures: true-to-scale design; change of datum system for tolerances; introduction of an additional dimension;

d) gauge pins: correction of dimensions and test procedures;

e) simplification of the clauses on quality assessment (Clause 5), preparation of a detail specification (Clause 6), and marking (Clause 7) by making direct reference to the generic specification IEC 61169-1;

f) introduction of an optional design for the coupling nut.
