1. A single-core transmission line transformer comprising:

  • a first transmission line wound around a solid core of magnetic material;

    a second transmission line wound around the solid core;

    a first port interconnecting respective first ends of the first transmission line and the second transmission line in parallel;

    a second port communicating with respective second ends of the first transmission line and the second transmission line; and

    a third transmission line communicating with the first transmission line and the second transmission line without being wound around any solid core, the third transmission line comprising a first side communicating with the respective first ends of the first transmission line and the second transmission line, and a second side communicating with the respective second ends of the first transmission line and the second transmission line,wherein the impedance transformation ratio of the single-core transmission line transformer is 1;

    9 in a direction from the first port to the second port.
