Abstract

　高い精度で、簡易に利得制御が可能な自動利得制御増幅装置を提供する。フィードバック利得制御回路（ＦＢ）３０に、受信信号を増幅又は減衰するＡＧＣアンプの増幅出力信号又は後段の出力信号ＤＩＮの電力値を検出する積分回路３１と、信号電力期待値Ｑに対して、例えば３ｄＢ単位の粗い精度の第１補正値Ａ１を算出して第１補正値記録回路３７に設定する比較回路（１）３２と、例えば０．５ｄＢ単位の細かな精度の第２補正値Ａ２を算出して第２補正値記録回路３８に設定する比較回路（２）３４とを備え、制御値算出回路３９にて、第１補正値Ａ１と第２補正値Ａ２との加算結果にｄＢ単位の利得制御単位ステップを乗算して第２の制御値ＣＦＢを出力し、予め設定されている第１の制御値、又は、受信信号の信号電力レベルを検出したＲＳＳＩ信号により生成した第３の制御値を補正することにより、ＡＧＣアンプに対する利得制御値を算出する。
