WG 2 - TC 46/SC 46F/WG 2

IEC 60153-4:2022 specifies straight hollow metallic tubing of circular cross section for use as waveguides in electronic equipment. The aim of this document is to specify the 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
This document is intended to be read in conjunction with IEC 60153-1, which gives general requirements and test methods. This fourth edition cancels and replaces the third edition published in 2017. edition:
a. change of the designation scheme for small circular waveguides (e.g. C 25.5k instead of C 25500);
b. revision of Table 1:
- correction of two waveguide designations (now C 1.2k, C 12k);
- correction of three waveguide diameters (C 140, C 1.4k, C 14k);
- tightening of inner diameter tolerances for waveguides smaller than C 890;
- deletion of waveguide attenuation values for aluminium, gold, and brass;
c. deletion of Table 2 (duplication) and replacement with the table of intermediate waveguide sizes originally envisaged here;
d. addition of an equation for calculating the attenuation of waveguides made of any material.

IEC 63249-1:2021 defines general requirements and test methods for waveguide to coaxial adapters. It includes terms and definitions, design and construction, ratings and characteristics, climatic categories, IEC type designation, requirements and test methods, quality assessment, marking, etc.
It provides the basis for establishing the sectional specifications for various waveguide to coaxial adapters.

IEC 60153-4:2017 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.
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.

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.

IEC 60154-2:2016 specifies the dimensions of flanges for ordinary rectangular waveguide for use in electronic equipment. It covers requirements for flanges drilled before or after mounting on waveguides. It should be noted that for optimum electrical performance, post-drilling of the alignment holes after mounting is recommended. The aim of this standard 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.
