CONTINUOUSLY VARIABLE MICROWAVE ATTENUATORS (Back to Top)
These types of specialized adjustable attenuators are essential when the need exists for Controlling Signal Levels "CONTINUOUSLY" without interrupting the Circuit under test. Ferrite absorption of the microwave energy is used, allowing for long term stability and high reliability. Some models use high precision micrometer drives which provide for a fraction of a "db" attenuation level control, a feature that "Stepped Attenuators" can not achieve!
