Abstract
A radio-frequency module includes a module substrate and a power amplification circuit that includes first to fourth amplification elements, a transformer including primary and secondary coils, an output terminal to which the secondary coil is connected, and a circuit component disposed on the module substrate. Output terminals of the first and third amplification elements and output terminals of the second and fourth amplification elements are respectively connected to a first terminal and a second terminal of the primary coil. A capacitor is connected to a wiring line path connected between the output terminal of the first amplification element and the first terminal of the primary coil and to a wiring line path connected between the output terminal of the second amplification element and the second terminal of the primary coil. The primary or secondary coil includes a conductive layer surrounding at least part of the circuit component.
