Radio-frequency connectors - Part 38: Sectional specification - Radio frequency coaxial connectors model, slide-in (rack and panel applications) - Characteristic impedance 50 O (type TMA) - 50 O applications (IEC 61169-38:2008)

This part of 61169, which is a sectional specification, provides information and rules for the preparation of detail specifications for series TMA r.f. connectors together with the pro forma blank detail specification. Series TMA connectors have a characteristic impedance of 50 Ω and are normally used with R.F cables or with microstrip in microwave fields that has a blind-entry and middle low-power. The connectors are usable up to a frequency of at least 6 GHz. This specification also prescribes mating face dimensions for general purpose connectors, dimensional details of standard test connectors grade 0, gauging information and tests selected from QC 220000 (IEC 61169-1), applicable to all detail specifications relating to series TMA 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.

La CEI 61169-38:2008 est une spécification intermédiaire (SS: Sectional Specification). Elle fournit des informations et des règles pour la préparation de spécifications particulières (DS: Detail Specification) pour les connecteurs RF de type TMA en série et le modèle pro-forma de la spécification particulière cadre. Les connecteurs de type TMA en série ont une impédance caractéristique de 50 Ω et sont normalement utilisés avec des câbles RF ou avec un micro-ruban dans des champs hyperfréquences ayant une entrée aveugle et une puissance basse moyenne. Les connecteurs peuvent être utilisés jusqu'à une fréquence pouvant atteindre au moins 6 GHz. La présente spécification prescrit également les dimensions des faces d'accouplement pour des connecteurs d'usage général, des informations détaillées sur les dimensions de connecteurs d'essais normalisés (catégorie 0), des informations sur les calibres et des essais choisis dans la norme QC 220000 (CEI 61169-1), applicables à toutes les spécifications particulières portant sur des connecteurs de type TMA en série. La présente spécification indique les caractéristiques de performance recommandées à prendre en considération pour rédiger une spécification particulière et elle porte sur des programmes d'essais et des exigences d'inspection pour les niveaux d'assurance M et H.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 61169-38 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.
This standard cancels and replaces IEC/PAS 61169-38 published in 2007.
The text of this standard is based on the following documents:

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 maintenance result 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.
A bilingual version of this publication may be issued at a later date.

3.4 General requirements for connector mounting in modules and on panels
3.4.1 Radial misalignment
The radial misalignment between engaging connectors refers to the coaxiality error A
(see Figure 7) between a connector with socket-centre contact and a connector with pin
centre contact at the beginning and during the engagement.
At the beginning of the engagement, the radial misalignment of rigidly mounted connector and
float-mounted connector shall no more than 0,51 mm.

IEC  1795/08

Figure 7 – The sketch map of connector radial misalignment
3.4.2 Axial misalignment
For rigidly mounted connector and float-mounted connector, the float mounting allows a total
of 1,52 mm (0,060 in) axial travel. The mounting arrangements should, however, ensure a
minimum length of travel of 0,26 mm (0,010 in) [0,76 mm (0,030 in) preferred ] to ensure that
full length of engagement is maintained under operational conditions (see Figure 8).
