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.
