摘要： 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).

摘要： An amplification unit 1 has an output connector 3 for outputting an RF signal output by an amplification circuit 2 for each amplification circuit. The output connectors 3 are disposed so as to be arranged in the horizontal direction. A combining unit 5 has an input connector 6 into which the RF signal output from the output connector 3 of the amplification unit 1 is input for each output connector 3. The input connectors are disposed so as to be arranged in the horizontal direction. The amplification unit 1 and the combining unit 5 are attachable/detachable through the output connectors 3 and the input connectors 6. The surface on which the input connectors are provided of the combining unit 5 is set within the dimension of the surface on which the output connectors are provided of the amplification unit 1.
