Fixed Attenuators
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 dB selection chart to look up your required dB value. A fixed attenuator can also be used to improve VSWR. Our VSWR reduction chart lists reduction levels for several standard dB values.

50 Ohm Fixed 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.- Selection chart for decreasing power level

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. [lt id="127"] -

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.Fixed Attenuators with Round Heatsinks

75 Ohm Fixed Attenuators
The name JFW has been synonymous with 75 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. Use our selection chart to look up your required dB value. All of our standard attenuator models do attenuate at DC. If you require the DC signal to be passed through the attenuator without being attenuated, then select a model in the table that is listed as DC Passing.
