Mid-Size Coaxial Attenuators
ARRA’s mid-size coaxial attenuators represent the most complete line of mid-size continuously variable attenuators available today.
Most attenuators have been qualified for all types of military applications. Since attenuation is achieved in a non-contacting manner, these units provide the utmost in wear-free performance and high reliability.
Units utilize ARRA’s proprietary dissipative materials and operate over extremely wide temperature ranges with little change in attenuation characteristics.
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.
