Abstract

A radio-frequency circuit includes: an amplifier; a matching circuit connected to an output side of the amplifier; and a power splitter connected to an output side of the matching circuit. The power splitter includes a differential inductor and a resistor element. The differential inductor includes an input node (ni), a first line, and a second line. The input node (ni) is connected to the matching circuit. The first line and the second line are respectively wound into coil form and connected to the input node (ni). The resistor element forms a connection between a node (n) on an output side of the first line and a node (n) on an output side of the second line. The first line and the second line are wound in opposite directions and have the same coil axis.
