EQUALIZER CIRCUIT USING ATT PAD

A high-power broadband optical receiver is disclosed. The high-power broadband optical receiver includes a photoelectric conversion diode (10) which receives an optical signal from an optical signal input terminal (1), converts the optical signal into an RF signal corresponding thereto, and outputs the RF signal; an ultrashort broadband AMP (20) which amplifies the RF signal lowered by photoelectric conversion; a frequency band divider (40) which filters the RF signal amplified by the ultrashort broadband AMP (20) to be divided into a plurality of amplifiable frequency bands; a first frequency band signal processing unit (50) which processes an RF signal of a first frequency band divided by the frequency band divider (40) into a high-power amplified form; a second frequency band signal processing unit (60) which processes an RF signal of a second frequency band divided by the frequency band divider (40) into a high-power amplified form; and a frequency band synthesizer (70) which synthesizes the RF signals respectively processed by the first frequency band signal processing unit (50) and the second frequency band signal processing unit (60) and outputs a synthesized RF signal to an RF output terminal (2).
