Pasternack's Circular Waveguide Calculator will calculate the cutoff frequency for the device from its radius.
Pasternack 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. Available waveguide components include waveguide to coax adapters, waveguide horn antennas, waveguide terminations (loads), waveguide sections and bends, plus more. Visit Pasternack'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.
