75 Ohm Single Rotor Manual Attenuators
The JFW 75 Ohm single rotary attenuator has been a staple tool to RF engineers for over 30 years. Our years of proven quality and performance make our manually variable attenuators right for any RF environment. Whether you are using the rotary attenuator at your RF test bench or mounting it to a panel, the JFW single rotary attenuator makes adjusting attenuation quick and easy.
Single Rotor Attenuator
All of these 75 Ohm manual step attenuators have a single rotor design which means that each attenuator has only one manual knob for adjusting attenuation. All manual knobs are screened with the attenuation steps for each model.
Panel Mount
All JFW rotary attenuators have threaded mounting holes on the front plate behind the knob. The knob has to be removed in order to mount the attenuator. We recommend setting attenuator to the 0dB position before removing the knob.
