Coaxial Attenuator from JFW Industries

The term coaxial attenuator is a general term that can be used to describe many types of attenuators. However, it is most commonly used to refer to a coaxial fixed attenuator which has a fixed attenuation value. A coaxial fixed attenuator is a passive two port device with coaxial connectors used to reduce the level of a RF signal. Insert the coaxial attenuator between the signal source and the device under test (DUT). The signal received by the DUT is reduced by the attenuation value of the coaxial fixed attenuator. The most important attributes of a coaxial attenuator are: Impedance, attenuation value, RF input power, frequency range and RF connector type. Attenuation value is determined by the amount of signal reduction required.

Signal reduction percentages for standard coaxial attenuator values:

  • 1 dB 20.567% signal reduction
  • 2 dB 36.904% signal reduction
  • 3 dB 49.881% signal reduction
  • 6 dB 74.881% signal reduction
  • 10 dB 90% signal reduction
  • 20 dB 99% signal reduction
  • 30 dB 99.9% signal reduction

JFW’s coaxial attenuators are sorted into four model charts:

In addition to fixed attenuators, JFW also manufactures a large variety of manually variable and programmable attenuators. All of our attenuators come in 50 and 75 ohm with a wide range of dB values available. Our manually variable attenuators also come in a variety of mounting options, like panel mount and benchtop options.  If you don’t find what you are looking for on our website, feel free to contact the JFW sales or engineering department and ask about our custom attenuator design options. JFW Industries is very happy to offer free no obligation product design quotes.
