Original Abstract Submitted

a radio frequency circuit supports a first power class and a second power class whose maximum output power is lower than that of the first power class, and includes: a first power amplifier; and a variable load matching circuit connected to an output end of the first power amplifier. under a condition that the first power class is applied, a first power supply voltage is supplied to the first power amplifier, and a load impedance viewed from the first power amplifier is adjusted to a first impedance by the variable load matching circuit. under a condition that the second power class is applied, a second power supply voltage is supplied to the first power amplifier, and the load impedance viewed from the first power amplifier is adjusted to a second impedance by the variable load matching circuit.
