IEEE 1785.1-2012 - IEEE Standard for Rectangular Metallic Waveguides and Their Interfaces for Frequencies of 110 GHz and Above?Part 1: Frequency Bands and Waveguide Dimensions
Specifications for the waveguide (including aperture dimensions, frequency range, cutoff frequency, etc.) are given in this standard. This standard considers the tolerances of the waveguide aperture dimensions and the effect these have on the electrical properties (in terms of return loss, transmission loss, etc.) of the waveguide.
IEEE 1785.3-2016 - IEEE Recommended Practice for Rectangular Metallic Waveguides and Their Interfaces for Frequencies of 110 GHz and Above?Part 3: Recommendations for Performance and Uncertainty Specifications
Recommendations for summarizing the performance and the expected uncertainty of the reflection coefficient of rectangular-waveguide apertures and interfaces for 110 GHz and above are provided in this recommended practice. The information provided also facilitates the development of a complete uncertainty analysis for the performance of rectangular waveguide interfaces. For example, it includes the dimensional information essential for calculating the uncertainty of both reflection and transmission coefficients through interfaces provided by different manufacturers if both follow this recommended practice.
