IEC 63138-2:2020

Multi-channel radio-frequency connectors - Part 2: Sectional specification for MQ4 series circular connectors

IEC 63138-2:2020, which is a sectional specification (SS), provides information and rules for the preparation of detail specifications (DS) for MQ4 series circular connectors with four RF channels, as well as a detailed specification of the blank format. An MQ4 series circular connector with 50 Ω nominal impedance has four RF channels which can be engaged and disengaged at the same time. There are two versions of plug connectors, one is a quick-lock version, and the other is a threaded version. The socket connector provides two coupling mechanisms, a quick-lock and a threaded coupling.
This document also specifies the mating face dimensions and gauging information of MQ4 series circular connectors, and tests selected from IEC 63138-1, applicable to all detail specifications relating to MQ4 series circular connectors.

Connecteurs radiofréquences multicanaux - Partie 2: Spécification intermédiaire pour les connecteurs circulaires de série MQ4

l’IEC 63138-2:2020, qui est une spécification intermédiaire (SS), fournit des informations et des règles pour l'établissement de spécifications particulières (DS) relatives aux connecteurs circulaires de série MQ4 disposant de quatre canaux RF, ainsi qu’une spécification particulière-cadre. Un connecteur circulaire de série MQ4 présentant une impédance nominale de 50 Ω dispose de quatre canaux RF pouvant être accouplés et désaccouplés en même temps. Il existe deux versions de connecteurs mâles: une première version à verrouillage rapide et une seconde version filetée. Le connecteur femelle offre deux mécanismes de couplage: un couplage par verrouillage rapide et un couplage fileté.
Le présent document spécifie également les dimensions de la face d’accouplement et les informations sur le calibre des connecteurs circulaires de série MQ4, ainsi que les essais choisis à partir de l’IEC 63138-1, applicables à toutes les spécifications particulières relatives aux connecteurs circulaires de série MQ4.

Part 2: Sectional specification for MQ4 series 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 s
