Description
Claims (1)
- 入力信号を複数に分配する分配手段と、
外部からの制御電圧に基づいて歪み補償の制御を行い、前記分配手段の出力に対して増幅と歪み補償を行った結果を出力する複数の共通増幅器と、
複数の前記共通増幅器の出力を合成し、外部へ出力する合成手段と、
前記合成手段の出力から残留歪みを検波し、前記制御電圧として複数の前記共通増幅器へ出力する受信手段とを備え、
前記複数の共通増幅器のそれぞれは、前記残留歪みの検波電圧を下げるための調整器と、前記受信手段からの前記制御電圧と閾値とに基づいて前記調整器を制御する制御部とを備えるとともに、
前記複数の共通増幅器の各制御部は、共通増幅器毎の歪み発生量に応じた補償量を与える前記閾値を保持していることを特徴とする増幅器。
