HOLLOW METALLIC WAVEGUIDES –
Part 4: Relevant specifications 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 60153-4 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.
This third edition cancels and replaces the second edition published in 1973-1. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Expand and revise the operation frequency range for waveguides;
b) Revise the allowance of aperture dimensions;
c) Revise the test method for aperture dimensions;
d) Revise the equation of attenuation.

HOLLOW METALLIC WAVEGUIDES –
Part 4: Relevant specifications for circular waveguides

1 Scope
This part of IEC 60153 specifies straight hollow metallic tubing of circular waveguides for use
as waveguides in electronic equipment.
The aim of this recommendation is to specify for hollow metallic waveguides:
a) the details necessary to ensure compatibility and, as far as essential, interchangeability;
b) test methods;
c) uniform requirements for the electrical and mechanical properties.
2 Normative references
The following documents are referred to in the text in such a way that some or all of their
content constitutes requirements of this document. For dated references, only the edition
cited applies. For undated references, the latest edition of the referenced document (including
any amendments) applies.

waveguides
IEC 60261, Sealing test for pressurized waveguide tubing and assemblies
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-726:1982
apply.
ISO and IEC maintain terminological databases for use in standardization at the following
addresses:
• IEC Electropedia: available at http://www.electropedia.org/

4 General
4.1 Standardized types
The series of circular waveguides covered by this publication are shown in Tables 1 and 2.
The preferred types are shown in Table 2. As it might be desirable to use circular waveguides
of intermediate sizes, Table 3 has been added in which the latter types are included.
4.2 Type designation
For these waveguides, the type designation comprises:
• The code: 60153 IEC-C
• A number characterizing a particular size of waveguide. This number expresses
‘approximately in multiples of 100 MHz the geometric mean frequency in the H (TE )
11 11
mode.
4.3 Frequency range
In Table 2, the cut-off frequencies are shown for the following modes:
TE , TM , TE , TE and TE .
