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

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l'ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l'électricité et de l'électronique. À cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d'études, aux
travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l'Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC intéressés
sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s'assure de l'exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l'éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d'encourager l'uniformité internationale, les Comités nationaux de l’IEC s'engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d'évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n'est responsable d'aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s'assurer qu'ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d'études et des Comités nationaux de l’IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l'utilisation de cette Publication de l’IEC ou de toute autre Publication de l’IEC,
ou au crédit qui lui est accordé.
8) L'attention est attirée sur les références normatives citées dans cette publication. L'utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L'IEC attire l'attention sur le fait que la mise en application du présent document peut entraîner l'utilisation d'un
ou de plusieurs brevets. L'IEC ne prend pas position quant à la preuve, à la validité et à l'applicabilité de tout
droit de brevet revendiqué à cet égard. À la date de publication du présent document, l'IEC n'a pas reçu
notification qu'un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois, il y a lieu
d'avertir les responsables de la mise en application du présent document que des informations plus récentes
sont susceptibles de figurer dans la base de données de brevets, disponible à l'adresse https://patents.iec.ch.
L'IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevets.
L'IEC 63138-4 a été établie par le sous-comité 46F: Composants passifs pour hyperfréquences
et radio fréquences, du comité d'études 46 de l'IEC: Câbles, fils, guides d'ondes, connecteurs,
composants passifs pour micro-onde et accessoires. Il s'agit d'une Norme internationale.
Cette édition annule et remplace l'IEC 61169-59:2017. Cette édition constitue une révision
technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à
l’IEC 61169-59:2017:
a) utilisation de l'IEC 63138-1:2019 comme spécification générique à la place de
l'IEC 61169-1:2013;
b) tous les paragraphes et toutes les méthodes d'essai correspondent à ceux de
l'IEC 63138-1:2019;
c) la dimension "g" dans le Tableau 3, le Tableau 4, le Tableau 7 et le Tableau 8 a été
modifiée, passant de "0,00 min. à 0,8 max." à "1,6 min. à 2,1 max.".

1 Domaine d'application
La présente partie de l'IEC 63138, qui est une spécification intermédiaire (SS, Sectional
Specification), fournit des informations et des règles pour l'établissement de spécifications
particulières (DS, Detail Specification) relatives aux connecteurs circulaires de type L32-4 et
L32-5 avec quatre canaux RF et cinq canaux RF, ainsi que d'une spécification particulière-
cadre.
Les connecteurs circulaires L32-4 et L32-5 avec une impédance nominale de 50 Ω comportent
quatre canaux RF et cinq canaux RF qui peuvent être accouplés et désaccouplés
simultanément. Ils sont caractérisés par des mécanismes de couplage filetés, un mécanisme
anti-insertion incorrecte, et la fréquence de fonctionnement de chaque canal s'étend jusqu'à
4 GHz. Ces connecteurs sont couramment utilisés au sein de systèmes de communication
mobile tels que TD-SCDMA et TD LTE, et peuvent également être utilisés dans d'autres
matériels similaires.
Le présent document spécifie également les dimensions de la face d'accouplement pour les
connecteurs à usage général (grade 2), les informations relatives au calibre et les essais
choisis à partir de l'IEC 63138-1, applicables à toutes les spécifications particulières relatives
aux connecteurs circulaires de type L32-4 et L32-5.

Multi-channel radio-frequency connectors -
Part 4: Sectional specification for type L32-4 and L32-5 circular
connectors
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.
IEC 63138-4 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. It is an International Standard.
This edition cancels and replaces IEC 61169-59:2017. This edition constitutes a technical
revision.
This edition includes the following significant technical changes with respect to
IEC 61169-59:2017:
a) use of IEC 63138-1:2019 as its generic specification instead of using IEC 61169-1:2013;
b) all the subclauses and test methods are in line with IEC 63138-1:2019;
c) dimension "g" in Table 3, Table 4, Table 7 and Table 8 has been changed from "0,00 min.
to 0,8 max." to "1,6 min. to 2,1 max.".
The text of this International Standard is based on the following documents:
Draft Report on voting
46F/XX/FDIS 46F/XX/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

1 Scope
This part of IEC 63138, which is a Sectional Specification (SS), provides information and rules
for the preparation of Detail Specifications (DS) for type L32-4 and L32-5 circular connectors
with four RF channels and five RF channels, as well as a detailed specification of the blank
format.
The L32-4 and L32-5 circular connectors with 50 Ω nominal impedance has four RF channels
and five RF channels which can be engaged and disengaged at the same time. They are
characterized by threaded coupling mechanisms, anti-misinsertion mechanism, and the
operating frequency of each channel is up to 4 GHz. These connectors have been widely used
in mobile communication system like TD-SCDMA and TD-LTE and can also be used in some
similar equipment.
This document also specifies mating face dimensions for general connectors (grade 2), gauging
information and tests selected from IEC 63138-1, applicable to all Detail Specifications relating
to type L32-4 and L32-5 circular connectors.

5 Quality assessment procedure
5.1 General
Subclauses 5.2 and 5.3 provide the recommended rating, performance and test conditions to
be considered when preparing a detail specification. They also specify the test schedules and
procedure that suit the corresponding quality inspection level.
5.2 Rating and characteristics
The values indicated in Table 11 are recommended for type L32-4 and L32-5 series circular
connector and are given for the writer of the detail specification. They are applicable for the
condition when the connectors are fully mated. The preferable characteristics can be seen in
Table 11.
Certain tests are listed without any recommended values being given when they are not required.
When such tests are required, appropriate values shall be entered in the detail specification at
the discretion of the specification writer.

6 Instructions for preparation of detail specifications
6.1 General
Detail specification (DS) writers shall use the appropriate Blank Detail Specification (BDS).
Clause 6 comprises the BDS dedicated for use with L32 series circular connectors. As such,
the BDS will already have information entered on it in relation to
– the basic specification number applicable to all the detail specifications covering connector
styles of the series covered by the Sectional Specification, and
– the connector series designation.
The specification writer should enter the details relating to the connector style to be covered by
the BDS, as indicated. The numbers in brackets in the BDS correspond to the indications in 6.2
to 6.5, which shall be given.
6.2 Identification of the component
(1) Enter the following details:
– style: the style designation of the connector including type of fixing and sealing if
applicable;
– attachment: by deletion of the inapplicable options of cable/wire given for centre and
outer conductors;
– special features and markings: as applicable;
– series designation: in bold characters/digits approximately 15 mm high.
(2) Enter details of assessment level and the climatic category.
(3) A reproduction of the outline drawing and details of the panel piercing (if applicable). It
shall provide the maximum envelope dimensions and the position of the reference plane.
In the case of a fixed connector, the position of the mounting plane relative to the front
face of the connector.
(4) Any maximum panel thickness limitations for fixed connectors shall be stated.
(5) Particulars of all variants covered by the DS. As appropriate, the information shall
include the following:
– cable types (or sizes) applicable to each variant;
– alternative plated or protective finishes;
– details of alternative mounting flanges having either tapped or plain mounting holes;
– details of alternative solder spills or solder buckets including, when applicable, those for
use with microwave integrated circuit (MIC) components.
6.3 Performance
(6) Performance data listing the most important characteristics of the connector in
accordance with the requirements of the relevant Sectional Specification. Deviations
from the minimum requirements shall be clearly indicated. Non-applicable parameters
shall be marked "na".
6.4 Marking, ordering information and related matters
(7) Insert marking and ordering information as appropriate, together with details of related
documents and any invoked structural similarity.
6.5 Selection of tests, test conditions and severities
(8) "na" shall be used to indicate non-applicable tests. All tests marked "a" by the Detail
Specification writer shall be mandatory.
When using the normal procedure with a dedicated BDS, the letter "a" – for "applicable" – shall
be entered in the "test required" column opposite each of the tests indicated as being mandatory
in the test schedule of the relevant Sectional Specification. Any additional test required at the
discretion of the specification writer shall also be indicated by an "a".
The Specification writer shall also indicate, when necessary, details of deviations from the
standard test methods and conditions including any relevant deviations given in the test
schedule of the Sectional Specification.
