Mega Industries’ rigid waveguide straight sections are available in a variety of waveguide sizes. We also design and manufacture rigid rectangular tube. MEGA covers a variety of frequency ranges up to 40 GHz. Full and reduced height configurations are available to meet your requirements. High power waveguide section sizes through WR6200 are also available on special request.

Mega Industries four-corner sprayarc argon® welding process is performed in precision fixtures on WR430 through WR2300. This ensures the highest quality waveguide, which is mechanically stable and designed for optimum electrical performance. We exceed EIA , IEC and Mil standards for both rectangular waveguide (IEC 60153-2, EIA RS-261, MIL-DTL-85 ) and cover flanges (IEC 60154-2, EIA RS-166, EIA RS-271, MIL-DTL-3922). Our standard models are commercial grade and military grade. For more information, please contact Mega Sales.
