Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a radio frequency front-end circuit and electronic equipment. Background technique [0002] With the popularization of mobile smart terminals, users' demand for data traffic continues to increase. For example, the peak rate of 5G NR can reach 20Gbps. The increase in rate requires 5G NR to have the capability of 4*4MIMO. The operating frequency required for electronic equipment is getting higher and higher, and the bandwidth is getting bigger and bigger, which challenges the limits of components. [0003] Generally, the functions of one transmit channel and four receive channels in the radio frequency front-end circuit can be realized by multiple three-pole three-throw switches. However, in the above method, the layout and routing of electronic devices will directly affect the path loss, and the three-pole three-throw switch will make the isolation between an...
