    • A first transmission line is formed on a first surface of a substrate. A first end of the first transmission line is connected to a transmission line of an unbalanced line. A second end is connected to a first transmission line of a balanced line. A second transmission line extends from a first end of the unbalanced line, alongside the first transmission line and spaced therefrom, and is connected to a second of the transmission lines of the balanced line. A ground plane is formed on a second surface of the substrate, extends from a first end of the balanced line, and is formed along the second transmission line to which the ground plane is connected through one or more vias. A width of a portion of the ground plane adjacent to the unbalanced line is greater than a portion thereof adjacent to the balanced line.
    • 第一传输线形成在基板的第一表面上。 第一传输线的第一端连接到不平衡线的传输线。 第二端连接到平衡线的第一传输线。 第二传输线从不平衡线的第一端沿着第一传输线延伸并与之隔开,并且连接到平衡线的第二传输线。 接地平面形成在基板的第二表面上,从平衡线的第一端延伸,并且沿着通过一个或多个通孔连接到接地平面的第二传输线形成。 与不平衡线相邻的接地面的一部分的宽度大于与平衡线相邻的部分的宽度。
