  • Power amplifying circuit and power amplifier
    Patent number: 11152893
    Abstract: A power amplifying circuit includes a first amplifying unit that amplifies a first radio-frequency signal and a second amplifying unit that amplifies a second radio-frequency signal. The first amplifying unit includes a first matching circuit that performs impedance matching for a circuit in a preceding stage, and a first amplifying circuit that amplifies the first radio-frequency signal that has passed through the first matching circuit. The second amplifying unit includes a second matching circuit that performs impedance matching for the circuit in the preceding stage, a resistor including a first end and a second end, the first end being electrically connected to the second matching circuit, and a second amplifying circuit that is electrically connected to the second end of the resistor and that amplifies the second radio-frequency signal that has passed through the resistor.
