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 61169-26 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee 46: Cables, wires, waveguides,
R.F. connectors, R.F. and microwave passive components and accessories.
The text of this standard is based on the following documents:
FDIS Report on voting
46F/220/FDIS 46F/225/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

A list of all parts of the IEC 61169 series, under the general title: Radio-frequency connectors,
can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

RADIO-FREQUENCY CONNECTORS –
Part 26: Sectional specification for TNCA series
RF coaxial connectors
1 Scope
This part of IEC 61169 which is a sectional specification (SS) provides information and rules
for the preparation of detail specifications (DS) for TNCA series RF coaxial connectors, with
characteristic impedance of 50 Ω, with threaded coupling and operating frequency limit up to
18 GHz, used in wireless, communication, instrument, antenna, test and measurements,
radar, and other fields, connecting with RF cables or micro-strips.
It also prescribes mating face dimensions for general connectors-grade 2, dimensional details
of standard test connectors-grade 0, gauging information and tests selected from
IEC 61169-1, applicable to all detail specifications relating to TNCA series connectors.
This specification indicates the 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 (see Tables 8 and 9).
TNCA connectors are recommended for applications above 11 GHz. TNCA connectors are
compatible with TNC connectors as described in the IEC 60169-17 and IEC 60169-26
provided that the dielectric of connector with socket-centre contact does not extend beyond
reference plane. However when mated with these connectors, the performances are not
ensured.
NOTE Attention is drawn to the fact that TNCA interface does not utilize overlapping PTFE dielectric for increased
voltage breakdown resistance.

retain the mass of the gauge in a vertical downward position. The test shall be carried out on
connector when the socket-centre contact is not removed.
