This standard will provide the relevant specifications for hollow
metallic rectangular waveguide operating at frequencies of 110 GHz and
The standard will be in two parts:
1) specifications for the waveguide (including aperture dimensions,
frequency range, cut-off frequency, etc);
2) specifications for the waveguide flanges (including engineering
This standard will also give the tolerances of the waveguide aperture
dimensions and the flanges, and the effect these will have on the
electrical properties (in terms of return loss, transmission loss, etc)
of the waveguide.
The purpose of this standard is to provide the agreed reference
for all organizations using rectangular waveguides at these frequencies.
This will enable efficient trade between customers and suppliers, and
common design criteria and practices for component, systems and design
