Rigid Waveguide

Mega Industries provides rigid waveguides in sizes WR90 through WR2300. Full height and reduced height configurations are available to meet your requirements. Custom sizes through WR6200 are also available on special request.

Mega Industries four-corner welding process is performed in precision fixtures on WR430 through WR2300 to insure the highest quality rigid waveguide, which is mechanically stable and designed for optimum electrical performance. Mega’s rigid waveguides meet or exceed EIA and Mil standards for both waveguide (RS-261A & MIL-DTL-85) and flanges (RS271-A & MIL-DTL-3922). Twist along the longitude axis is less than 1° per foot and less than 1/2° overall. Flange flatness tolerances are less than .01 per inch and less than 10° mils overall.

Our rigid waveguides are manufactured from 6061-T6 aluminum alloy; however, sizes WR90 through WR650 are also available in Copper alloys. Aluminum waveguides are given a chromate conversion treatment per MIL-C-5541, Class 1A

Waveguide Flanges & Gaskets

Flush waveguide flanges either in 6061-T6 aluminum plate or 356-T6 aluminum castings are readily available for prototype fabrication or field installation. These waveguide flanges are premachined to EIA dimensions and are of sufficient thickness to allow a minimum of 1/8” for facing after machining. Special bolt hole patterns, double flanges, 4:1 aspect ratios, grooves and alignment pins can be readily supplied to meet special feed system requirements.

To insure optimum high power performance of a waveguide feed assembly, MEGA INDUSTRIES recommends that a low positive pressure be utilized within the waveguide feed. Our waveguide gaskets provide the proper electrical and mechanical seal for interior or exterior use.

Each hardware kit contains stainless steel hex-head bolts, flat washers, lock washers and nuts for a complete waveguide flange joint. Please call with any questions regarding our waveguide flanges or waveguide gaskets.
