Description
電力増幅器56は、VGA54から供給される信号の電力を増幅し、それによって、増幅された送信信号を生成するよう動作可能である。例示的な実施例では、電力増幅器56は、複数のカスケード段を備え、一般に、その入力電力と出力電力との間での線形性を必要とする。本発明の原理によれば、電力増幅器56の最終段のバイアス電流を、電力増幅器56の非線形効果に帰することができる3次相互変調積の検出電力レベルに基づいて送信モード中に適応的に制御することができる。電力増幅器56のこのバイアス電流を制御することによって、本発明は効果的には、適用可能な出力電力スペクトル・マスクによるその線形性要件も満たす一方でその電力消費を削減することができる。電力増幅器56の更なる詳細は以下本明細書に記載する。
