Waveguides

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. Our waveguides are commonly used for millimeter wave communications requiring low loss capabilities, typically not possible with coaxial cables only. Common applications for these waveguides include radar systems for their high power capabilities, antenna feed networks for low loss and phase accuracy and test labs.

Waveguides are available in standard sizes from WR-430 through WR-28, which encompasses frequencies from 1.7 GHz to 40 GHz. With regards to a waveguide’s size, the term “WR-xxx” stands for “Waveguide Rectangular”; the number indicates the inner width dimension of the waveguide in hundredths of an inch. Our entire line of waveguides are constructed with aluminum bodies for its lightweight characteristics. We carry both waveguide adapters, waveguide horns and waveguide terminations with square or rectangular flanges.
