Zusammenfassung:The utility model relates to a distributor with a power amplification function for a cable TV terminal user, which comprises an attenuator, a three-stage amplifier and three distributors, the frequency of the utility model is 45MHz to 750MHz, and the flatness is +/-2 dB. Thus, the distributor with a power amplification function has good flatness. The maximal input of the distributor with a power amplification function is 78 dbmuV. A C2570 triode of the NEC company in Japan is used for amplifying. As the circuit design is used, the flatness is easy to control, operation is stable, and bulk production is convenient.
