Abstract
The radio frequency power amplifier is connected between an other end of the first switching element and an other end of the second switching element, supplies power to a second amplifier via the first switching element and a second matching circuit, and includes a first power supply line for supplying power to the third amplifier via a second switching element and a third matching circuit, and the other end of the first switching element is connected to an input node of the first matching circuit, the other end of the second switching element is connected to the input node of the first matching circuit via the first power supply line, and an impedance of an output side of the RF power amplifier as viewed from an output node of the third amplifier is higher than an impedance of the RF power amplifier as viewed from an output node of the second amplifier.
