本发明的目的在于提供能够抑制损耗发生的电路基板及分波电路。;本发明的特征在于，具备：基板主体；输入讯号线路导体，设置于基板主体，且被包含在输入路径中；第1安装部，设置于基板主体的主面，且被包含在第1输出路径中，安装了由集总参数元件构成的高通滤波器；第1输出讯号线路导体，至少有1个以上，设置于基板主体，且被包含在第1输出路径中；以及第2安装部，设置于基板主体的主面，且被包含在第2输出路径中，安装了由集总参数元件构成的低通滤波器，设置于讯号传输方向的最上游侧的第1输出讯号线路导体是透过安装于基板主体主面的第1集总参数元件与输入讯号线路导体相连接。; an input signal line conductor with which the substrate body is provided and included in an input path; a first mounting portion provided on a main surface of the substrate body, included in a first output path and on which a high-pass filter composed of a lumped-parameter element is mounted; at least one first output signal line conductor with which the substrate body is provided and included in the first output path; and a second mounting portion provided on the main surface of the substrate body, included in a second output path and on which a low-pass filter composed of a lumped-parameter element is mounted. The first output signal line conductor provided furthest upstream in a signal propagation direction is connected to the input signal line conductor via a first lumped-parameter element mounted on the main surface of the substrate body. |
