Pushbutton Attenuators
Pushbutton AttenuatorsThe JFW pushbutton attenuator has been a staple tool to RF engineers for over 30 years. Whether mounted to a panel or used at a RF test bench, the JFW pushbutton attenuator makes adjusting attenuation quick and easy.
Step Attenuator Design
Each pushbutton controls an individual attenuation step. In order to achieve combinational dB settings you must activate multiple attenuation steps simultaneously.
Panel Mount Options
Most JFW pushbutton attenuators have threaded mounting holes on the same side as pushbuttons. These mounting holes are denoted on the outline drawings.
