Abstract
A transformer includes a first transmission line disposed on a main surface of a first layer, and having a first end into which an input signal is inputted, and a second end electrically connected to an output terminal, and a second transmission line having a first end electrically connected to the first end of the first transmission line and a second end grounded, the second transmission line being disposed on a main surface of a second layer different from the first layer, the second transmission line being electromagnetically coupled to the first transmission line and in which an electric current that flows in a direction opposite to a direction of an electric current flowing through the first transmission line is induced.
Claims10
A transformer, comprising:
- a first transmission line on a main surface of a first layer, and having a first end into which an input signal is input, and a second end electrically connected to an output terminal;
- and
- a second transmission line having a first end electrically connected to the first end of the first transmission line and a second end that is grounded, the second transmission line being on a main surface of a second layer, and being electromagnetically coupled to the first transmission line,
- wherein the second layer is different from the first layer, and is laminated to the first layer in a lamination direction,
- wherein an electric current flowing through the second transmission line is induced by and flows in a direction opposite to an electric current flowing through the first transmission line,
- wherein either one of the first transmission line and the second transmission line comprises a first wire and a second wire connected in parallel with the first wire at a location where the first transmission line and the second transmission line overlap each other when viewed in the lamination direction of the first layer and the second layer.
