RF front-end devices and electronics

Abstract

The application discloses a radio frequency front-end device and electronic equipment. The device includes: a first radio frequency channel; a second radio frequency channel; a first radio frequency module. The first radio frequency module includes a medium and high frequency amplifier module and a first switch module. The amplification module connects the first radio frequency channel and the second radio frequency channel through the first switch module, and the first switch module is used to control the medium and high frequency amplifier module to connect the first radio frequency channel or the second radio frequency channel; the second radio frequency module, The second radio frequency module includes a low frequency amplifier module and a second switch module, the low frequency amplifier module is connected to the first radio frequency channel and the second radio frequency channel through the second switch module, and the second switch module is used to control the connection of the low frequency amplifier module through the first radio frequency channel or the second radio frequency channel; the third radio frequency module, the third radio frequency module includes a 5G amplifier module, and the 5G amplifier module is connected to the second radio frequency channel. Thus, different EN‑DC combination configurations between 4G and 5G refarming frequency bands can be realized without increasing the number of RF 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 radio Dual 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 designi...
