    • An amplitude controller for adjusting the amplitude of a radio-frequency signal, the amplitude controller comprising means for splitting (302A) an amplitude adjustment input signal into one or more signal pairs, each signal pair comprising two partial signals, means for generating (302B) an inverse-phase-sized phase difference between the partial signals of each signal pair, means for adjusting (302C, 302D, 302F) the amplitudes of the partial signals of each signal pair by employing the mutual magnitude of the amplitudes of the partial signals as the factor controlling the adjustment, and means for summing up (302E) the partial inverse-phased and amplitude-adjusted signals as an output signal.
    • 一种幅度控制器,用于调节射频信号的幅度,所述幅度控制器包括用于将振幅调整输入信号分离(302A)成一个或多个信号对的装置,每个包括两个部分信号的信号对,用于产生(302B) 每个信号对的部分信号之间的反相位大小的相位差,用于通过采用部分信号的幅度的相互幅度来调整(302C,302D,302F)每个信号对的部分信号的幅度的装置 控制调整的因子以及用于将部分反相和幅度调整信号相加(302E)作为输出信号的装置。
