MANUALLY VARIABLE ATTENUATORS The JFW rotary attenuator has been a staple to RF engineers for more than 30 years. In that time, our line of manually variable step attenuators has grown to include over 700 models. With a wide variety of attenuation ranges, step sizes and tuning options, JFW has solutions to fit almost any variable attenuator application. At JFW Industries, we can literally put reliable attenuation at your fingertips. Our years of proven quality and performance make a JFW variable attenuator right for any RF environment. AVAILABLE FEATURES ● Variable attenuators covering frequency ranges from DC to 18 GHz ● Multiple attenuator tuning options (rotor, dual-concentric rotors, push-button, toggle switch or rocker switch) ● Attenuations step sizes as low as 0.1 dB resolution ● 50 Ohm and 75 Ohm attenuators (other impedance values also available upon request) ● Any RF connector combination (BNC, SMA, N, TNC, F reverse polarity and more) ● Available on 19” rack panels or in stackable bench-top boxes AFFORDABLE CUSTOM DESIGNS ARE ALSO AVAILABLE!
