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.
