Model 50F-XXX-BNC fixed attenuator 50 Ohm 1Watt BNC male/female

50 Ohm Fixed Attenuator rated for 2 Watts with BNC male/female connectorsFixed Attenuators (0.5 to 2 Watts)

The name JFW has been synonymous with 50 Ohm fixed attenuators since our inception in 1979.  JFW has the capabilities to match custom dB values with a variety of RF connector combinations to make a fixed attenuator for your specific application.

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.  Here are two selections charts to help determine which dB value you need.

DC Passing Attenuators

DC passing attenuators will pass the DC signal through the attenuator without being attenuated.  They only attenuate over the specified frequency band.
