The invention discloses a radio frequency circuit, electronic equipment and a radio frequency control method, and belongs to the technical field of communication. The radio frequency circuit comprises a radio frequency transceiver, a phase discriminator, at least two channels and at least two antennas, each channel comprises a radio frequency transceiver module, a coupler and a power divider, and the radio frequency transceiver module, the coupler and one antenna in each channel are connected in sequence; the input end of the power divider is connected with the coupling output end of the coupler so as to divide a signal received from the coupler into a plurality of signals and then output the signals; the input end of the phase discriminator is connected with the power divider in each channel so as to determine the phase difference between the signals received from the power divider in each channel; and the radio frequency transceiver is respectively connected with the phase discriminator and the radio frequency transceiver module and the power divider in each channel so as to respectively send a corresponding signal to each radio frequency transceiver module and adjust the phase of the signal sent to any radio frequency transceiver module based on the phase difference received from the phase discriminator.
Description
technical field [0001] The application belongs to the technical field of communication, and in particular relates to a radio frequency circuit, electronic equipment and a radio frequency control method. Background technique [0002] In order to increase the uplink transmission rate and reduce the data transmission delay to meet consumers' requirements for uplink data transmission, a radio frequency architecture based on Multiple-Input Multiple-Output (MIMO) technology emerges as the times require. [0003] In order to ensure the data transmission rate, the existing MIMO radio frequency architecture is usually designed in such a way that the transmission power of each channel is time-divisionally controlled by the radio frequency transceiver to realize data transmission. For example, taking the uplink data transmission process as an example, the radio frequency transceiver transmits a corresponding signal to each channel based on the uplink data to be transmitted, detects the...
