Abstract
A radio frequency circuit includes carrier and peak amplifiers, a transformer, and an impedance converting circuit. One end of an input coil is connected to an output of the carrier amplifier, one end of an output coil is connected to an output terminal. The impedance converting circuit includes main and auxiliary lines. One end of the main line is connected to an output of the peak amplifier, and the other end of the main line is connected to the other end of the input coil. One end of the auxiliary line is connected to the one end of the main line, and the other end of the auxiliary line is connected to ground. A first direction from the one end to the other end of the main line, and a second direction from the other end to the one end of the auxiliary line are the same.
