Continuously Variable Attenuators, DC - 1 Ghz Low Frequency
Narda-MITEQ manufactures a wide variety of Continuously Variable Attenuators, Level Set, and Low Frequency "CVA" Attenuators. While there exists some overlap in performance between different attenuator models, careful review of the mechanical outline drawings and the corresponding tables should reveal the proper variable attenuator model for your microwave application.
Narda-MITEQ also manufactures a line of Rotary Stepped Attenuators for RF applications where stops are required at particular attenuation levels.
As always, please call us to discuss your RF Variable Attenuator requirements with one of our microwave design engineers. Note: "CVA" is used to mean: Continuously Variable Attenuator.
