Abstract

The embodiment of the invention provides a radio frequency circuit and electronic equipment, and the radio frequency circuit comprises at least four antennas which are used for sending uplink detection reference signals of a first SIM card to a base station in turn in a time division mode in each transmission period; and the at least four antennas are also used for transmitting 5G radio frequencysignals of a second SIM card in the transmitting period. The radio frequency circuit transmits 5G radio frequency signals of a second SIM card in an SRS signal transmitting period of the first SIM card at the same time. Therefore, the 5G radio frequency signal of the first SIM card and the 5G radio frequency signal of the second SIM card can be transmitted on at least four antennas of the radio frequency circuit at the same time. The at least four antennas are shared by the 5G radio frequency signal of the first SIM card and the 5G radio frequency signal of the second SIM card, so that the number of the antennas of the radio frequency circuit can be reduced, the occupation of the antennas on the internal space of the electronic equipment can be reduced, and the internal space utilization rate of the electronic equipment can be improved.

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...
