Abstract

The invention provides a radio frequency front-end circuit and a mobile terminal. The circuit comprises a first double-pole double-throw switch; a first signal receiving circuit which is connected with one of the first antenna and the second antenna through a first double-pole double-throw switch and receives signals through the connected antenna; a second double-pole double-throw switch; a secondsignal receiving circuit which is connected with one of the third antenna and the fourth antenna through a second double-pole double-throw switch and receives signals through the connected antenna; athird double-pole double-throw switch which is respectively connected with the first double-pole double-throw switch and the second double-pole double-throw switch; a first radio frequency circuit which is connected with the third double-pole double-throw switch and comprises a signal receiving mode or a signal transmitting mode; And a second radio frequency circuit which is connected with the third double-pole double-throw switch and comprises a signal receiving mode or a signal transmitting mode. The circuit is simple in design, radio frequency layout wiring can be shortened on the basis that signal transmitting and/or receiving are/is achieved, and therefore path difference loss is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of terminal applications, and in particular to a radio frequency front-end circuit and a mobile terminal. Background technique [0002] With the rapid development of Internet communication technology and the continuous popularization of mobile smart terminals, users' demand for data traffic is also increasing. From 4G's transmission rate of 100Mbps to 1Gbps, to 5G NR's peak transmission rate of up to 20Gbps, the rate increase requires 5G to have 4*4 Multiple Input Multiple Output (Multiple Input Multiple Output, MIMO) key technology. [0003] Such as figure 1 As shown, it is a schematic structural diagram of the RF front-end circuit of a 5G mobile terminal device. This circuit architecture is used to realize one transmission and four reception 1T4R and two transmission and four reception 2T4R. Among them, the layout and routing of 5G mobile terminal equipment directly affect the path l...
