Zomwave's Circular Waveguide Calculator will calculate the cutoff frequency for the device from its radius.
Zomwave 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-12, which encompasses frequencies from 1.7 GHz to 90 GHz.
**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.
