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.UHV Attenuators Coaxial Variable Attenuators
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.
