The waveguide calculator calculates the cutoff frequencies for a rectangular waveguide and the impedance and guided wavelength at a given operating frequency.
| lower cutoff: | GHz |
| cutoff next mode: | GHz |
| minimum operating frequency: | GHz |
| maximum operating frequency: | GHz |
| free space wavelength: | mm |
| guided wavelength: | mm |
| \( Z_0 \) | \( \mathrm{\Omega} \) |
| \( \beta \) | \(\frac{1}{\mathrm{m}} \) |
