Abstract

The invention discloses a radio frequency front-end circuit and terminal equipment. The radio frequency front-end circuit comprises a switching module, and a plurality of radio frequency modules whichare electrically connected with the switching module, each of the plurality of radio frequency modules is used for receiving or sending signals of a plurality of frequency bands, and at least one frequency band in the plurality of frequency bands received or sent by the plurality of radio frequency modules is the same. The radio frequency front-end circuit supports the functions of downlink 4 * 4MIMO, uplink 2 * 2 MIMO, downlink 2 * 2 MIMO, independent networking, non-independent networking double connection and the like.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a radio frequency front-end circuit and terminal equipment. Background technique [0002] 5G is also known as the fifth-generation mobile communication technology. 5G is the main direction of the development of the new generation of mobile communication technology and an important part of the future new generation of information infrastructure. Compared with 4G (fourth generation mobile communication technology), 5G will further enhance the user's network experience, and will also meet the application requirements of the Internet of Everything in the future. The RF front-end (RFFE) circuit has always been an important part of mobile phone design. The RF front-end circuit is the functional area between the RF transceiver and the antenna of the mobile phone. It is mainly composed of a power amplifier (PA), a low-noise amplifier (LNA), and a switch (Switch ), duplexer (Duplex...
