Description
光受信サブアセンブリ1は、左方より入射された光変調信号を電気信号に変換し、差動信号を出力する。その差動出力信号は、2本の出力リードピンを通じてフレキシブル基板2上の伝送線路3および4に出力される。その出力信号は、主基板5上の配線パタンを通じて直流分離用容量7、8、平衡型減衰器回路を構成する抵抗9、10、11、12および平衡型減衰回路と並列に接続した容量13、14を通過した後、ポストアンプ6に入力される。
ポストアンプ6は、可変利得(AGC)アンプICやアンプ内蔵CDR(Clock and Data Recovery)IC等を用いる。なお、ポストアンプ6の出力は、図示を省いた。
実施例2において、実施例1との違いは周波数特性補償回路104を平衡H型減衰回路と並列接続容量素子113、114とで構成した点にある。平衡H型減衰回路を構成する抵抗素子108、109、110、111、112の抵抗値は所望の減衰量を実現できる値を選び、ここではそれぞれ15Ω、15Ω、15Ω、15Ω、180Ωとする。並列接続容量素子113、114の容量値は、所望の補償特性が得られる値に調整し、ここでは1.2pFとする。
