1.0 GHz Variable Attenuators produce flat (even) loss across Cable TV
forward and reverse frequency band. The attenuators are used during amplifier
balancing to adjust amplifier signal levels as needed. The variable loss
produced (dB) is between 0 dB to 10 dB or 0 dB to 20 dB. The attenuators are
rated for operation up to 1.0 GHz. Within specific amplifier types, the
attenuators are also used as equalizers.
