Waveguide-to-Coax

Waveguide-to-Coax Adapters

Frontgrade Waveguide-to-Coax Adapters are constructed of aluminum or copper and cover waveguide sizes WR - 22 through WR - 430. Most models achieve a VSWR of 1.10 over the full waveguide bandwidth or that of the coaxial connector selected. In addition, Frontgrade is happy to work with you on custom design configurations to accommodate Additional sizes including reduced height, extended range, and more.
