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.
