Overview

EN IEC 61169-10:2024 is the sectional specification (SS) for RF coaxial connectors Type SMB with an inner diameter of the outer conductor of 3 mm (0.12 in), snap-on coupling, and characteristic impedance 50 Ω. Aligned with IEC 61169-1, this standard provides rules and templates for preparing detail specifications (DS) for SMB series connectors, prescribing mating-face dimensions, gauging, test requirements and recommended performance characteristics. It applies to SMB connectors used to interface RF cables and microstrips in microwave transmission systems with an operating frequency up to 4 GHz.

Key topics and requirements

• Purpose and scope: Defines the structure and content required for detail specifications for series SMB RF coaxial connectors (50 Ω, snap-on).
• Mating-face dimensions: Specifies dimensions for high-performance connectors (grade 2) and dimensional details for standard test connectors (grade 0).
• Gauging information: Includes gauge pin and outer-contact gauge definitions to ensure interchangeability and conformance.
• Quality assessment: Outlines ratings and characteristics, acceptance and periodic test schedules, and inspection requirements for assessment levels M and H.
• Test selection: References tests and measuring methods selected from IEC 61169-1 and related EMC/test methods (e.g., IEC 62153-4-7) for transfer impedance and screening attenuation.
• Detail specification guidance: Provides instructions and a blank pro-forma for preparing DS documents, including marking, ordering, and selection of test severities.

Applications

• Connecting RF cables and microstrip lines in microwave transmission systems.
• Use cases include telecommunications equipment, RF test and measurement setups, and other electronic systems requiring reliable 50 Ω SMB interfaces up to 4 GHz.
• Ensures mechanical and electrical interoperability, reliable performance, and consistent test methods for SMB connectors across suppliers.

Who should use this standard

• Connector designers and manufacturers preparing detail specifications (DS) for SMB series products.
• Quality and test laboratories performing acceptance and periodic testing to the standard’s schedules.
• Procurement and engineering teams specifying connectors for RF/microwave systems.
• Regulatory and conformity-assessment bodies referencing standardized test and gauging methods.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
