Podrobnosti návrhu

This part of the IEC 60153 series of standards specifies straight hollow metallic tubing[1] of ordinary rectangular cross-section for use as waveguides in radio frequency electrical applications. The principal cross-section for such tubing is shown in Figure 1 together with its defining geometrical dimensions: a (inside width), b (inside height), r (inside corner radius), t (wall thickness), a1 (outside width), b1 (outside height), and r1 (outside corner radius).

The dimensions shown in Figure 1 are also defined elsewhere in this standard.

The term “ordinary rectangular waveguide” in the title of this standard refers to rectangular waveguides with a b-to-a ratio of 1:2 (or slightly less).

The objective of this standard 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.

No recommendations are made for the materials to be used for waveguides. The choice of materials is to be agreed between the customer and the manufacturer.

This standard shall be read in conjunction with IEC 60153-1, which gives general requirements and test methods.
