Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a radio frequency circuit and an electronic device. Background technique [0002] With the rapid development of Internet communication technology and the continuous popularization of electronic devices, users' demands for data traffic are also increasing. The transmission rate of 4G ranges from 100Mbps to 1Gbps, and the peak transmission rate of 5G NR can reach 20Gbps. The increase in rate requires 5G to have 4*4 Multiple Input Multiple Output (MIMO) key technology. [0003] like figure 1 As shown, it is a schematic structural diagram of a radio frequency circuit of an electronic device supporting 5G in the related art. The radio frequency transmit signal is the signal after mixing the local oscillator signal and the baseband signal. The radio frequency circuit includes a radio frequency transceiver, the radio frequency transceiver includes a local osci...
