In dividing units (12 and 22), signals propagating between input ports (P1) and output ports (P4) and between input ports (P2) and output ports (P3) have phases shifted by 90° from phases of signals propagating between the input ports (P1) and the output ports (P3) and between the input ports (P2) and the output ports (P4). Amplifiers (21 and 22) output amplified signals that are in phase to the dividing units (12 and 22). A combining and dividing unit (13) outputs a combined signal obtained by combining signals from the output ports (P3) of the dividing units (12 and 22) to an input port (P1) of a combining unit (30). A combining and dividing unit (23) outputs a combined signal obtained by combining signals from the output ports (P4) of the dividing units (12 and 22) to an input port (P2) of a combining unit (30). |
