Radio frequency circuit and terminal equipment

Abstract

The embodiment of the invention discloses a radio frequency circuit and terminal equipment. The radio frequency circuit comprises a radio frequency control module, a first radio frequency transmit-receive module, a second radio frequency transmit-receive module, a first frequency division module, a second frequency division module, a first switch and a plurality of antennas. The radio frequency control module is used for controlling the first radio frequency receiving and transmitting module to receive and transmit a first frequency band radio frequency signal through the first frequency division module, the first switch and the corresponding antenna; and the first radio frequency transceiving module and the second radio frequency transceiving module are controlled to receive the radio frequency signal of the first frequency band and transmit and receive the radio frequency signal of the second frequency band through the second frequency division module and the corresponding antenna respectively. According to the technical scheme of the embodiment of the invention, the structure of the radio frequency circuit is simplified, the layout area of the radio frequency device is reduced,the design cost of the radio frequency circuit is reduced, the radio frequency performance and the feasibility of the radio frequency circuit are improved, and the commercialization of communication products is facilitated.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of communication, and in particular, to a radio frequency circuit and a terminal device. Background technique [0002] With the increasing demand for mobile data, the fifth generation of mobile communication technology 5G has become a hot topic in the communication industry. At present, major operators have unclear requirements and standards for 5G communications. The RF solution and antenna design are relatively complex. Too many RF devices, switches, and antennas in the RF circuit will result in high overall design costs and affect RF performance. It is not conducive to the promotion of 5G communication. Contents of the invention [0003] The present invention provides a radio frequency circuit and terminal equipment to simplify the structure of the radio frequency circuit, reduce the layout area of ​​the radio frequency device, reduce the design cost of the radio frequency cir...
