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:全文を表示する
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.
