Mega manufactures waveguide attenuators in fixed and variable precision. Our attenuators range in sizes from WR-28 to WR-2300. We cover a wide array of frequencies and specialize in high power attenuators. Our attenuators cover the frequency range of 0.32 GHz to 40 GHz. Low to medium power devices utilize high density shaped microwave absorbing elements, which are permanently attached to a standard waveguide section.
The VSWR of the fixed attenuators is less than 1.10.1 over a 10% band. The variable units exhibit a 1.15:1 maximum VSWR. When requested, calibration charts traceable to the National Bureau of Standards can be supplied.
Hybrid Style Attenuators
For extremely high power and low loss applications, Mega offers hybrid-style variable waveguide attenuators. These exhibit a minimum insertion loss of 0.05 db. However, they 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 wide array of high power, low frequency rigid and flexible waveguide products. Our common size range is WR28 through WR2300. However, custom designs through WR5900 are available upon special request.
We typically manufacture waveguide from 6061-T6 aluminum alloy. However, sizes WR90 through WR650 are available in copper and aluminum alloys. Furthermore, flanges and gaskets are provided in accordance with EIA and Military Specifications.UHV Attenuators Coaxial Variable Attenuators
Attenuators are manufactured to precise tolerances. We calculate this to provide optimum VSWR and maximum power handling capabilities.
In addition, Mega offers a complete line of components to complete or refurbish your waveguide systems. These include flexguide, miter bends, sweeps, quadrature hybrids, a variety of tees, transformers, transition, gas barriers, couplers, terminations, circulators, phase shifters and tuners.
