1.8GHz JXP-P Attenuators

Query

1.8 GHz JXP Attenuators produce flat (even) loss across Cable TV forward and reverse frequency band to support Docsis 3.1 standard. . The pads are used during amplifier balancing to adjust amplifier signal levels as needed. The fixed loss produced (dB) is equal to the value printed on the top of each pad. The pads listed below are rated for operation up to 1.8 GHz. Within specific amplifier types, the pads are also used as equalizers.

These pads can be used for amplifiers, line extenders, nodes, combiners, etc.
