Miniature Attenuators 1-18 GHz

Miniature Attenuators 1-18 GHz

These units represent the most complete line of miniature continuously variable attenuators. 

Most models weigh 2 or 3 ounces and have been qualified for all types of military applications. Since attenuation is achieved in a non-contacting manner, these units provide the most in wear-free performance and high reliability.

Applications

The standard forms are ideal for applications where attenuation can be set, then locked and left for long periods of time without movement. The panel-mount version is ideally suited for applications where front panel adjustment is required and monitored via output power.
Turns-counting dials are ideally suited for panel mount applications where calibration or reference for resetting is required.

The digital counter version performs the same task as the turns-counting dial but with greater resolution. Both T & D options can be calibrated by utilizing a calibration chart. Order CT or CD option.
