Abstract

The embodiment of the invention provides a radio frequency circuit and electronic equipment, and the radio frequency circuit comprises a first modem which is used for processing 4G radio frequency signals; a second modem which is used for processing the 5G radio frequency signal; at least two first antennas which are used for transmitting 4G network signals of the first SIM card; at least two second antennas which are used for transmitting 5G network signals of the second SIM card; and at least two third antennas which are used for transmitting the 4G network signal of the first SIM card and transmitting the 5G network signal of the second SIM card. When the radio frequency circuit transmits 4G network signals of the first SIM card and 5G network signals of the second SIM card, the 5G network and the 4G network can coexist under the condition of two SIM cards by sharing at least two antennas, 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 is 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 (The 5th Generation Mobile Communication Technology, 5G) is gradually emerging. [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 an electronic device to support both 4G network and 5G network through two SIM cards, it is necessary to set multiple independent antennas ...
