Radio frequency front-end device and electronic device

Abstract

The invention discloses a radio frequency front-end device and an electronic device. The device comprises a first radio frequency path; a second radio frequency path; a first radio frequency module, comprising a first 5G amplification module, a medium-high frequency amplification module and a first switch module, the first 5G amplification module being connected with the second radio frequency path, and the medium-high frequency amplification module being connected with the first radio frequency path and the second radio frequency path through the first switch module; and a second radio frequency module, comprising a second 5G amplification module, a low-frequency amplification module and a second switch module. The second 5G amplification module is connected with the second radio frequency path, and the low-frequency amplification module is connected with the first radio frequency path and the second radio frequency path through the second switch module. Therefore, different EN-DC combination configurations between the 4G frequency band and the 5G refarming frequency band can be realized under the condition of not increasing the number of the radio frequency channels.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a radio frequency front-end device and electronic equipment. Background technique [0002] 2019 is defined as the first year of 5G communication, and major communication operators around the world are also officially launching the construction of 5G mobile communication networks this year. Considering that the cost of 5G SA (stand alone, independent networking) is too high, most domestic and foreign Most operators choose to adopt NSA (Non-standalone, non-independent networking), that is, EN-DC (E-UTRA and New radioDual Connectivity, dual connection between 4G wireless access network and 5G new air interface) in the early stage. EN-DC means that the entire RF front-end architecture will become more complex. At the same time, some operators propose to refarming the traditional 600MHz-2700MHz frequency band, which will further increase the difficulty of designin...
