Mega Industries produces both fixed and variable precision waveguide attenuators for the most demanding system requirements in sizes ranging from WR-28 to WR-2300. Low to medium power devices utilize high density shaped microwave absorbing elements permanently attached to a standard waveguide section. The VSWR of the fixed attenuators is less than 1.10.1 over a 10% band and the variable units exhibit a 1.15:1 maximum VSWR. When requested, calibration charts traceable to the National Bureau of Standards can be supplied.
For extremely high power or for low loss applications, hybrid style variable waveguide attenuators are available. These units, which exhibit a minimum insertion loss of 0.05 db can be readily varied to 30 db attenuation under full transmitter power. Both manual drive and motor driven devices are available to meet the most exacting requirements.
Mega produces a comprehensive line of high power, low frequency rigid and flexible waveguide products and accessories ranging in sizes from WR28 through WR2300. Larger sizes are offered through WR5900 upon special request.
Mega Industries waveguide attenuators are typically manufactured from 6061-T6 aluminum alloy, however, sizes WR090 through WR650 are available in either copper or aluminum alloys. Waveguide flanges and gaskets are provided in accordance with EIA and Military Specifications.UHV Attenuators Coaxial Variable Attenuators
Mega Industries waveguide attenuators are manufactured to precise tolerances calculated to provide optimum VSWR and maximum power handling capabilities.
In addition to waveguide attenuators, Mega offers a complete line of components to complete or refurbish your systems. These include flexible waveguide, miter bends, sweep bends, quadrature hybrids, magic tees, folded tees, series and shunt tees, transformers, transition, gas barriers, couplers, terminations, circulators, phase shifters and tuners.
A trusted name in high power microwave technology since 1989, Mega Industries is a world leader in the design manufacture of microwave transmission equipment. Please contact Mega Industries about your specific waveguide attenuator needs.
