  • Patent number: 10483915
    Abstract: The application provides a radio frequency circuit, including: a first circuit and a second circuit. The first circuit is configured to receive a first signal and a second signal; split the first signal into a third signal and a fourth signal, and split the second signal into a fifth signal and a sixth signal; adjust a phase of the fifth signal to obtain a seventh signal; and combine the seventh signal and the third signal into an eighth signal. The second circuit includes a primary power amplifier branch and a secondary power amplifier branch, and the primary power amplifier branch is configured to process the fourth signal and the sixth signal, and the secondary power amplifier branch is configured to process the eighth signal.

  • Patent number: 10432146
    Abstract: Embodiments of the present application provide a power amplifier, a power amplification method, and a power amplification control apparatus and method. The power amplifier includes n Doherty power amplification units connected in parallel and an n-way outphasing combiner, where n?2 and n is an integer. Each Doherty power amplification unit includes one input end and one output end. The n-way outphasing combiner includes n input ends and one output end. The output ends of the Doherty power amplification units are separately connected to the input ends of the n-way outphasing combiner.
