Abstract: Embodiments of this application provide a communication device. The communication device includes a first splitter, a first transmit path, and a second transmit path, where the first transmit path includes a first phase shifter and a first power amplifier, and the second transmit path includes a second phase shifter and a second power amplifier; an output end of the first transmit path is coupled to a first transmit antenna, and an output end of the second transmit path is coupled to a second transmit antenna; an input end of the first transmit path and an input end of the second transmit path are separately coupled to the splitter; the first transmit path and the second transmit path are configured to transmit a beamforming signal; and the first transmit path and the second transmit path are further configured to transmit a multiple-input-multiple-output MIMO signal.
