Description
SMA Rotary Variable Attenuator – 0–90 dB, 10 dB steps, DC–6 GHz
The RF POWER® SMA rotary variable attenuator by CentronRF adjusts attenuation from 0–90 dB in 10 dB steps across DC–6 GHz. Turn the dial to change the signal level without breaking the RF path, which makes it ideal inside test set-ups and equipment where you need fast, repeatable level changes.
It is built for low VSWR (≤1.50), high attenuation accuracy and long life: under normal use the rotary mechanism is rated for more than 5,000 operations.

FAQ
Rotary attenuator or step attenuator: which do I need?
Both change attenuation in steps. A rotary attenuator uses a dial and compact SMA body that is easy to build into equipment; push-button step attenuators are common on the bench.
Can I get other ranges or step sizes?
Yes. Contact us for other attenuation ranges, step sizes, power ratings or connector types.
