  1.2 GHz SJ-2C 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 1.2 GHz. Within specific amplifier types, the attenuators are also used as equalizers.
