Connector Frequencies: Waveguides
By: Jean-Jacques DeLisle
The size of rectangular waveguides is given in a code, waveguide rectangular - # (WR-#). The # in the waveguide size code corresponds to the larger dimensions wall size in mils divided by 10. In the reference, “Waveguide Connector Frequencies” a visual table of the frequency range of operation of the common rectangular waveguide sizes is provided. The frequency band, waveguide code, frequency range, and a side-by-side view of the waveguide frequency range against a frequency bar are shown with spatial accuracy. This allows for a straight edge to be placed across the waveguide of interest and an active comparison of several common frequency designations can be easily viewed.
For a side-by-side comparison of coaxial and rectangular waveguide connectors, see “Coaxial & Waveguide Connector Frequencies.”
