The radio frequency circuit includes: a radio frequency transceiver, a phase detector, at least two channels and at least two antennas, each channel includes a radio frequency transceiver module, a coupler and a power divider, wherein the radio frequency transceiver module in each channel, The coupler and an antenna 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 the signal received from the coupler into multiple signals and then output; the input end of the phase detector is connected to each channel The power divider is connected to determine the phase difference between the signals received from the power divider in each channel; the RF transceiver is connected to the phase detector and the RF transceiver module and power divider in each channel respectively, Corresponding signals are sent to each radio frequency transceiver module, and the phase of the signal sent to any radio frequency transceiver module is adjusted based on the phase difference received from the phase detector.
Description
technical field [0001] The present application belongs to the field of communication technologies, and in particular relates to a radio frequency circuit, an electronic device 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' demands for uplink data transmission, a radio frequency architecture based on the Multiple-Input Multiple-Output (MIMO) technology has emerged. [0003] In order to ensure the data transmission rate, the existing MIMO radio frequency architecture is usually designed to realize data transmission in a manner that the radio frequency transceiver performs time-division control on the transmit power of each channel. 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 transmit powe...
