Abstract

An embodiment of the present application provides a radio frequency circuit and electronic equipment, where the radio frequency circuit includes: at least four antennas, configured to send the uplink sounding reference signal of the first SIM card to the base station in turn in a time-division manner in each transmission cycle; The at least four antennas are also used to transmit 5G radio frequency signals of the second SIM card during the transmission period. The radio frequency circuit simultaneously transmits the 5G radio frequency signal of the second SIM card during the SRS signal transmission period of the first SIM card, thereby simultaneously transmitting the 5G radio frequency signal of the first SIM card on at least four antennas of the radio frequency circuit. signal and the 5G radio frequency signal of the second SIM card, to realize the sharing of the 5G radio frequency signal of the first SIM card and the 5G radio frequency signal of the second SIM card to the at least four antennas, so the number of antennas of the radio frequency circuit can be reduced, and the The antenna occupies the internal space of the electronic device, thereby improving the utilization rate of the internal space of the electronic device.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a radio frequency circuit and electronic equipment. Background technique [0002] With the rapid development of communication technology, the fourth generation mobile communication technology (The 4th Generation Mobile Communication Technology, 4G) has gradually been difficult to meet the needs of users, especially the needs of users for higher network speed and lower network delay. Subsequently, the fifth generation mobile communication technology (The5th Generation Mobile Communication Technology, 5G) gradually rises. [0003] Currently, electronic devices such as smart phones are usually provided with two Subscriber Identification Modules (Subscriber Identification Module, SIM, SIM card for short). In order for the electronic device to support the dual-card dual-standby function of two SIM cards, two sets of independent radio frequency communication syste...
