    • 一種阻抗轉換裝置具有四個導體,這些導體經配置而使得第一與第二導體形成具有第一特徵阻抗之傳輸線;第三與第四導體形成具有第一特徵阻抗之傳輸線;第一與第三導體形成具有第二特徵阻抗之傳輸線;且第二與第四導體形成具有第二特徵阻抗之傳輸線。第二與第四導體是經由等於第一特徵阻抗之電阻而互連於鄰近末端處。第三與第四導體是經由等於第二特徵阻抗之電阻而互連於鄰近末端處。阻抗轉換裝置之橫向尺寸足夠小以允許插入於疊對線中。 An impedance conversion device has four conductors arranged so thatthe first and second conductors form a transmission line having a first characteristic impedance, the third and fourth conductors form a transmission line having the first characteristic impedance, the first and third conductors form a transmission line having a second characteristic impedance, and the second and fourth conductors form a third transmission line having the second characteristic impedance. The second and fourth conductors are interconnected at proximate ends through a resistance equal to the first characteristic impedance. The third and fourth conductors are interconnected at proximate ends through a resistance equal to the second characteristic impedance. The lateral dimensions of the impedance conversion device are small enough to permit insertion in a stacked pair line.
