0-70dB SMA RF Variable Attenuator 6GHz with 1dB step

Dec. 23, 2020

RF Variable attenuators are very much similar to Fixed attenuators. The only difference is that one can select an attenuation value in a step attenuator by using digital control or manually by push-buttons or by a rotary switch.

Variable attenuators are used in laboratories, when it is necessary to obtain small value of voltage or current for testing purposes.
