Abstract (en)
[origin: EP0432729A2] A radio frequency signal combining/sorting apparatus which includes a plurality of channel filters (F1, --- and F64) which allow band regions of respective transmission channels to pass through them, isolators (IN1, --- and IN64) connected to respective inputs of the channel filters, a plurality of sets of power composing circuits (JU1,JU2,JU3,JU4) each including branch lines for composing outputs of the channel filters as one output, and hybrid circuits (H1 to H3) arranged to compose outputs per two sets of the power composing circuits (JU1,JU2,JU3,JU4). The band regions of the respective channel filters are selected in such relation that the band regions of the respective channel filters of the same power composing circuit are spaced from each other to a largest extent. <IMAGE>
