摘要：マルチポート増幅器を調整する方法及びマルチポート増幅器を提供する。マルチポート増幅器は、並列に配置した偶数個のマイクロ波電力増幅器（Ａ１乃至Ａ８）、一連の入力ポート（ｐ１乃至ｐ８）、及び一連の出力ポート（ｑ１乃至ｑ８）を含み、入力ポートは、一連の入力混成回路（Ａ乃至Ｍ）によって増幅器に接続され、また、出力ポートは、一連の出力混成回路（Ａ乃至Ｍ）によって増幅器に接続される。これらによって、任意の所定入力ポートの入力信号は、全ての増幅器によって増幅され、そして、再合成され所定出力ポートの出力信号になる。本方法は、全出力ポート間の許容可能な信号絶縁を保証可能にしつつも、一対の隣接増幅器の片方の増幅器を他方の増幅器に、対でない増幅器間の整合より大きい程度に整合する段階を含む。本調整方法により、ＭＰＡは、幾つかの周波数再利用方式の要件に良好に適合し、また、セットアップ及び試験時間が大幅に減少する。

摘要： A method and apparatus for modifying interactions between an electrical generator and a nonlinear load is described. One illustrative embodiment receives a main control signal at a control input of an engine of the electrical generator, the main control signal controlling at least one of output power, output current, and output voltage delivered by the electrical generator to the nonlinear load, the engine being one of a power amplifier and a converter; measures the impedance of the nonlinear load; and feeds to the electrical generator a compensation signal corresponding to the measured impedance, the compensation signal rendering a transfer function of the output power of the electrical generator with respect to the main control signal substantially insensitive to variations in the impedance of the nonlinear load to stabilize the output power of the electrical generator.
