Flanges for waveguides - Part 4: Relevant specifications for flanges for circular waveguides

IEC 60154-4:2017 specifies the dimensions of flanges for circular waveguides for use in electronic equipment.
It covers requirements for flanges drilled before or after mounting on waveguides.
The aim of this document is to specify for waveguide flanges the mechanical requirements necessary to ensure compatibility and, as far as practicable, interchangeability as well as to ensure adequate electrical performance.
This edition includes the following significant technical changes with respect to the previous edition:
- revise the estimation for return loss at connection interface of waveguides;
- add two type of waveguide flange for high frequency application, i.e. over 50 GHz;
- expand the operation frequency range up to 3,3 THz;
- rename the frequency band over R1200, i.e. R1.2K.

Brides pour guides d'ondes - Partie 4: Spécifications particulières applicables aux brides pour guides d'ondes circulaires

L'IEC 60154-4:2017 spécifie les dimensions des brides pour guides d'ondes circulaires pour utilisation dans les équipements électroniques.
Elle couvre les exigences applicables aux brides percées avant ou après montage sur les guides d'ondes.
Le présent document a pour but de spécifier des exigences mécaniques applicables aux brides pour guides d'ondes qui sont nécessaires pour assurer la compatibilité et, autant que possible, l'interchangeabilité, mais aussi pour assurer des performances électriques suffisantes.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
- révision de l'estimation de l'affaiblissement de réflexion au niveau de l'interface de connexion de guides d'ondes;
- ajout de deux types de brides de guides d'ondes pour les applications à haute fréquence, c'est-à-dire au-delà de 50 GHz;
- extension de la plage de fréquences de travail jusqu'à 3,3 THz;
- attribution d'un nouveau nom à la bande de fréquences R1200, à savoir R1.2K.

FLANGES FOR WAVEGUIDES –
Part 4: Relevant specifications for flanges for circular waveguides

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 60154-4 has been prepared by subcommittee 46F: RF and
microwave passive components, of IEC technical committee TC 46: Cables, wires,
waveguides, RF connectors, RF and microwave passive components and accessories.
