    • A radio frequency signal combining/sorting apparatus which includes a plurality of channel filters which allow band regions of respective transmission channels to pass through them, isolators connected to respective inputs of the channel filters, a plurality of sets of power composing circuits each including branch lines for composing outputs of the channel filters into one output, and hybrid circuits arranged to each compose the outputs per two sets of the power composing circuits. The band regions to be applied to the respective channel filters are selected in such relation that the band regions of the respective channel filters corresponding to a given power composing circuit are spaced from each other to the largest possible extent.
    • 一种射频信号组合/分类装置,其包括允许各个传输信道的频带区域通过它们的多个信道滤波器,连接到信道滤波器的相应输入端的隔离器,多组功率合成电路,每组包括分支线路 用于将信道滤波器的输出组合成一个输出,以及混合电路,每个组合电路组合每两组功率合成电路的输出。 选择要施加到各个信道滤波器的频带区域,使得对应于给定功率合成电路的各个信道滤波器的频带区域以最大可能的程度相互间隔开。
