Problems solved by technology

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 designing the RF front-end architecture of mobile terminals.

Embodiment Construction

[0020] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0021] This application proposes to hang the low-frequency PAMID (low-frequency amplification module) and the medium-high frequency PAMID (medium-high frequency amplification module) on different ET (Envelop tracking, envelope tracking) power supply paths, and at the same time, the low-frequency PAMID and the medium-high frequency PAMID can pass The RF switch selects different transmission channels, and one of the two sets of 5G amplifier modules NR (5G new radio, 5G new air interface) PA is connected to the same ET power sup...

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, and the first radio frequency module includes a first 5G amplification module, a medium and high frequency amplification module and a A switch module, the first 5G amplifier module is connected to the second radio frequency channel, and the medium and high frequency amplifier module is connected to the first radio frequency channel and the second radio frequency channel through the first switch module; the second radio frequency module includes the second radio frequency module Two 5G amplifier modules, low frequency amplifier modules and a second switch module, the second 5G amplifier module is connected to the second radio frequency channel, and the low frequency amplifier module is connected to the first radio frequency channel and the second radio frequency channel through the second switch module. 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 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...
