Abstract
An impedance conversion device has four conductors arranged so that the 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.
