A single-core transmission line transformer includes first, second and third transmission lines, and first and second ports. The first and second transmission lines are wound around a common core. The first port interconnects respective first ends of the first and second transmission lines in parallel. The second port communicates with respective second ends of the first and second transmission lines. The third transmission line communicates with the first and second transmission lines without being wound around any solid core. The impedance transformation ratio of the transformer is 1:9 in a direction from the first port to the second port.
