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.
