50 Ohm Fixed Attenuators
(5 to 50 Watts)

The name JFW has been synonymous with 50 Ohm fixed attenuators since our inception in 1979.  Our attenuators are used in RF labs, integrated into RF sub systems, and installed into cellular base stations.  We stock a wide selection of fixed attenuators with standard dB values (3, 6, 10, 20, 30dB) and RF connectors (BNC, N, SMA, TNC). We also manufacture fixed attenuators with custom dB values and mixed RF connector combinations.

An attenuator is used to decrease the power level of a RF signal. A fixed attenuator is an attenuator that has a single fixed dB value.  When purchasing a fixed attenuator you have to specify which dB value you require.  Use our selection chart to look up your required dB value.

For your specific application, please contact JFW or use our Inquiry Form.
