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 selection chart to look up your required dB value.

    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"]
