Waveguide Calculator (Rectangular)

Fairview Microwave's Waveguide Calculator provides the cutoff frequency, operating frequency range and closest waveguide size for a rectangular waveguide based on the custom inputted broad wall width.

Note: If you select a waveguide size from the dropdown below, the broad wall width will be automatically calculated along with the other results.

Fairview Microwave waveguides are structures for guiding electromagnetic waves, often called a waveguide transmission line. Our waveguides are low loss transmission lines capable of handling high power with high isolation. Waveguides are available in standard sizes from WR-430 through WR-15, which encompasses frequencies from 1.7 GHz to 75 GHz.

Available waveguide components include waveguide to coax adapters, waveguide horn antennas, waveguide terminations (loads), waveguide sections and bends, plus more. Visit Fairview Microwave's Waveguides page for product details.

**Note: All of our calculators allow SI prefix input. For example, if you wish to input "25000000", just type "25M" instead. See the quick-reference table below for all compatible SI prefixes.

Prefix	Symbol	Value
Tera	'T'	10¹²
Giga	'G'	10⁹
Mega	'M'	10⁶
kilo	'k'	10³

Prefix	Symbol	Value
pico	'p'	10^-12
nano	'n'	10^-9
micro	'u'	10^-6
milli	'm'	10^-3
