  Level Set Attenuators

The Level Set Attenuator is used to adjust power, reduce reflection interaction, and provide isolation where needed. Adjustment is accomplished by loosening the clamping screws and raising or lowering the mylar vane by hand until the desired attenuation value is achieved and then re-tightening the screws. These attenuators provide reliable performance when continuously variable settings are not required.

CMI Offers these parts made from coin silver waveguide as a custom product. Send email to for quote.
