Radio-frequency connectors. Part 15: Sectional specification - RF coaxial connectors with inner diameter of outer conductor 4,13 mm (0,163 in) with threaded coupling - Characteristic impedance 50 Ω (Type SMA) (IEC 61169-15:2021)

This part of IEC 61169, which is a sectional specification (SS), provides information and rules
for the preparation of detail specifications (DS) for RF coaxial connectors with inner diameter
of outer conductor 4,13 mm (0,163 in) with threaded coupling with a characteristic impedance
of 50 Ω (type SMA).
This document specifies mating face dimensions for high performance connectors – grade 1,
dimensional details of standard test connectors – grade 0, gauging information and tests
selected from IEC 61169-1, applicable to all detail specifications relating to series SMA RF
connectors.
This document indicates recommended performance characteristics to be considered when
writing a detail specification and it covers test schedules and inspection requirements for
assessment levels M and H.
The SMA types RF coaxial connectors are used with all kinds of RF cables and microstrips in
microwave transmission systems. The operating frequency is up to 18 GHz. These connectors
can be intermated with 3,5 mm (IEEE 287-2007) and 2,92 mm (IEC 61169-35) connectors.
NOTE Metric dimensions are original dimensions. All undimensioned pictorial configurations are for reference
purpose only.

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61169-15 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,
RF connectors, RF and microwave passive components and accessories.
This first edition cancels and replaces IEC 60169-15 published in 1979 and the amendment 1
published in 1996. This edition constitutes a technical revision.

Choose tolerance to give the requirement of 50 Ω. For non-center contact connector, dimension p may
deviate from the values given when the centre conductor of the cable is used as the contact pin. In this case,
the inner diameter of the outer conductor is identical to the outer conductor of the cable.

Dimension q should be such that the reference planes coincide, and the connectors meet the required
environmental performance.

The test procedure is as follows:
a) Sizing test
The gauge A shall be inserted into the socket-centre contact three times. This is a sizing
operation and should only be carried out when the socket-centre contact is removed from
the connector.
b) Insertion test
Following the sizing operation, and if required in the detail specification, the force
necessary to insert gauge B fully into the socket-centre contact shall be measured. When
this test is required, the maximum permitted insertion force shall then be specified and
shall not exceed 13,3 N.
c) Retention test
After the sizing test, the gauge B shall be inserted into socket-centre contact. The contact
shall retain the mass of the gauge B in a vertical downward position.

5 Quality assessment procedures
5.1 General
Subclauses 5.2 to 5.3 provide recommended ratings, performance and test conditions to be
considered when writing a detail specification (DS). They also provide an appropriate
schedule of tests with minimum levels of conformance inspection sampling, together with the
pro forma blank detail specification (BDS) and instructions for the preparation of a detail
specification.
5.2 Ratings and characteristics
Preferred climatic categories are given in Table 6.
The values indicated below are recommended for SMA series RF connectors and are given
for the writer of the detail specification. They are applicable for the condition when the
connectors are fully mated. Rating and characteristics are given in Table 7.
Certain tests are listed without any recommended values being given. These tests will usually
not be required. When these tests are required, appropriate values shall be entered in the
detail specification at the discretion of the specification writer.
Table 6 – Preferred climatic categories
Climate type Grade * Temperature range Steady damp heat
40/85/21 A − 40 °C to + 85 °C 21 days
55/125/21 B − 55 °C to + 125 °C 21 days
55/155/56 C − 55 °C to + 155 °C 56 days
