IEC 60153-3:1964 pdf download,Hollow metallic waveguides. Part 3: Relevant specifications for flat rectangular waveguides.
IEC 60153-3:1964 establishes relevant specifications for flat rectangular hollow metallic waveguides. These waveguides are used to guide electromagnetic energy, particularly at microwave frequencies, through a metallic structure having a rectangular cross-section with one dimension substantially larger than the other. The standard provides a common technical basis for their design, manufacture, interchangeability, inspection, and application.
The document addresses the principal dimensional and mechanical characteristics needed to define flat rectangular waveguides. These include internal and external dimensions, wall thickness, dimensional tolerances, straightness, surface condition, material, joints, and other constructional features that can influence electromagnetic performance. It also considers the accuracy and continuity of the internal conducting surfaces, since irregularities, deformation, corrosion, or poor joints may increase loss and reflection.
Relevant interface and connection details are specified so that waveguide sections, bends, flanges, couplings, and associated components can be assembled consistently. The document also provides a basis for checking electrical characteristics such as transmission behavior, attenuation, impedance matching, reflection, and power-handling capability, insofar as these depend on the specified geometry and workmanship.
IEC 60153-3:1964 is therefore primarily a dimensional, mechanical, and performance-reference specification rather than a complete application guide. It supports manufacturers, users, laboratories, and equipment designers in producing and selecting compatible flat rectangular waveguide components for radar, telecommunications, instrumentation, and other high-frequency systems.
