Abstract

The invention provides a radio frequency front-end circuit and a mobile terminal. The circuit includes: a gating switch, respectively connected to the first antenna, the second antenna, and a radio frequency circuit module; a double-pole double throw switch, respectively connected to the gating switch, the third antenna, the fourth antenna, and the first radio frequency circuit; wherein, The radio frequency circuit module is connected to the first target antenna in the first antenna and the second antenna through the gating switch, and receives and / or transmits signals through the first target antenna; or, the radio frequency circuit module is through the gating switch, dual The pole double throw switch is connected with the second target antenna in the third antenna and the fourth antenna, and receives and / or transmits signals through the second target antenna; the first radio frequency circuit is connected with the third antenna and the third antenna through the double pole double throw switch. One of the fourth antennas is connected. The circuit design of the invention is simple, and on the basis of realizing signal transmission and / or reception, it can shorten radio frequency layout and wiring, thereby reducing path loss.

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...
