INTERNATIONAL ELECTROTECHNICAL COMMISSION
HOLLOW METALLIC WAVEGUIDES
Part 6: Relevant specifications for medium flat rectangular waveguides
FOREWORD
1)
The formal decisions or agreements of the IEC on technical matters, prepared by Technical Committees on which all the
National Committees having a special interest therein are represented, express, as nearly as possible, an international
consensus of opinion on the subjects dealt with.
2)
They have the form of recommendations for international use and they are accepted by the National Committees in that
sense.
3) In order to promote this inte
rnational unification, the IEC expresses the wish that all National Committees having as
yet no national rules, when preparing such rules, should use the IEC recommendations as the fundamental basis for these
rules in so far as national conditions will permit.
4)
The desirability is recognized of extending inte rn
ational agreement on these matters through an endeavour to harmonize
national standardization rules with these recommendations in so far as national conditions will permit. The National
Committees pledge their influence towards that end.
PREFACE
This Recommendation was prepared by Sub-Committee 46B, Waveguides and their Accessories,
of IEC Technical Committee No. 46, Cables, Wires, and Waveguides for Telecommunication Equipment.
It contains Part 6: Relevant Specifications for Medium Flat Waveguides, of the complete 1EC Recom-
mendation for Hollow Metallic Waveguides, and it is intended to be used in conjunction with Part 1,
General Requirements and Measuring Methods, which is issued as IEC Publication 153-1.
Relevant specifications for other types of waveguides will appear in companion publications.
The general outline of this Recommendation was first discussed at a meeting held in Ulm in 1959.
A draft was prepared which was considered at the meeting held in Interlaken in 1961. As a result of this
latter meeting, a draft was submitted to the National Committees for approval under the Six Months' Rule
in February 1962.
Several countries submitted comments which were informally considered during the meeting held in
Bucharest in 1962. as the voting period had not yet expired by that time. Based on the comments received,
some amendments were submitted to the National Committees for approval under the Two Months' Pro-
cedure in January 1965. Some comments were discussed and accepted at the meeting held in Baden-Baden
in 1965.
The following countries voted explicitly in favour of publication of Part 6:
Australia
Netherlands
Belgium
Norway
Canada
Poland
Czechoslovakia
Romania
Denmark
Sweden
Finland Switzerland
France
Turkey
Hungary
United Kingdom
India
United States of America
Italy
Yugoslavia

HOLLOW METALLIC WAVEGUIDES
Part 6: Relevant specifications for medium flat rectangular waveguides
MEDIUM FLAT RECTANGULAR WAVEGUIDES — TYPE M
Clause No. of
IEC Publication Item
153-1
1. General
Standardized types
The series of medium flat rectangular waveguides covered by this publication
are shown in Table I.
1.2 Type designation
For these waveguides the type designation comprises:
a) The code: 153 IEC-M
b) A number characterizing a particular size of waveguide. This number
expresses approximately in multiples of 100 MHz (Mc/s) the geometric
mean frequency of the recommended frequency range.
Frequency range
The frequency range indicated in Table I is from 1.25 to 1.9 times the cut-off
frequency in the dominant mode. For any particular type of application, the
working frequency range may be smaller or greater than the frequency range
given in the table.
2. Mechanical requirements
It should be noted that no recommendations are made for the materials to be
used for waveguides. The choice of material must be a greed between customer
and manufacturer.
2.1 Dimensions
2.1.6.1 Inside dimensions
The tolerances both on width and height shalt be approximately:
± 1/1 000
of the inside nominal width.

Clause No. of
Item
IEC Publication
153-1
2.1.6.1 The nominal values and the tolerances are specified in Table I.
(cont. )
2.1.6.2 Wall thickness
The nominal values are specified in Table I.
Eccentricity
2.1.6.3
The eccentricity shall not exceed 10% of the nominal wall thickness.
2.1.6.4 Outside dimensions
The tolerance both on width and height is approximately: ± 1/500 of the
inside nominal width. The nominal values and tolerances are specified in
Table I.
2.1.6.5 Rectangularity of cross-section
The rectangularity of inside and outside cross-section shall conform to the
requirements specified in Part I of this publication.
2.2 Other mechanical requirements
2.2.1 Bow
The bow shall conform to the requirements specified in Part I of this publi-
cation.
2.2.2 Twist
The twist shall conform to the requirements specified in Part 1 of this publi-
cation.
2.2.3 Surface roughness
Surface roughness shall conform to the requirements specified in Part I of
this publication.
2.2.4 Internal stress
Test procedure and requirements shall conform to Part I of this publication.

3. Electrical tests
3.1 Attenuation
The maximum attenuation shall not exceed 1.3 times the values calculated
from formula (1) in Part I at a frequency of 1.5 times the cut-off frequency.
The values given in the table are for waveguides made of copper with standard
resistivity = 1.7241.10-8 ohm.metre.
po
3.2 Irregularity of characteristic impedance
Irregularity of characteristic impedance shall conform to the requirements
specified in Part I of this publication.
4. Additional tests
4.1 Gas tightness
Gas tightness shall conform to the requirements specified in Part I of this
publication.
