Abstract
A power amplification circuit includes a first amplifier that amplifies a signal split from an input signal, a second amplifier that amplifies a signal having a different phase from the aforementioned signal, third and fourth amplifiers, and a matching network. The matching network includes a first wiring having a first end connected to an output terminal of the first amplifier and a second end connected to an input terminal of the third amplifier, a second wiring having a first end connected to the input terminal of the third amplifier, and electromagnetically coupled to the first wiring, a third wiring having a first end connected to an output terminal of the second amplifier and a second end connected to an input terminal of the fourth amplifier, and a fourth wiring having a first end connected to the input terminal of the fourth amplifier, and electromagnetically coupled to the third wiring.
