  • Millimeter Wave Continuously Variable Waveguide Attenuators

    Fairview Microwave Inc.

    Our millimeter wave variable waveguide attenuators allow designers and engineers to test their systems at various signal strengths and attenuation values to determine the optimum signal performance of the system. The key feature of these waveguide attenuators is that the attenuation level is adjusted using a built-in micrometer which enables repeatable and rapid re-setting to different attenuation levels without the need for additional external components. Our waveguide attenuators handle varying attenuation levels from 0 to 30 dB over the specified band allowing the designer to tune the attenuation level needed for the application. These continuously variable waveguide attenuators cover a broad frequency range of 33 to 110 GHz in five bands and also display flat performance across a wide band with low insertion loss.
