Abstract

The invention provides a radio frequency front-end circuit and a mobile terminal. The circuit comprises a first signal transmitting circuit and a second signal transmitting circuit, a first change-over switch and a second change-over switch; and a double-pole double-throw switch. The first signal emission circuit is conducted through the first double-pole double-throw switch and the first change-over switch, and emits a signal through the first antenna or the second antenna. Or the first signal transmitting circuit is conducted through the first double-pole double-throw switch and the second change-over switch and transmits signals through the third antenna or the fourth antenna. The second signal transmitting circuit is conducted through the first double-pole double-throw switch and the first change-over switch and transmits a signal through the first antenna or the second antenna. Or the second signal transmitting circuit is conducted through the first double-pole double-throw switchand the second change-over switch and transmits signals through the third antenna or the fourth antenna. The circuit design is simple, the radio frequency layout wiring can be shortened, and the pathdifference 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...
