Abstract

The disclosure belongs to the technical field of terminal equipment, and specifically relates to a radio frequency circuit and its control method, terminal equipment, and amplifier system. The radio frequency circuit includes: a control module, a first antenna, a second antenna, an outdoor antenna interface, and a switch module; The first antenna is connected to the control module and is used to send and receive signals of the first preset frequency band; the second antenna is used to send and receive signals of the first preset frequency band; the outdoor antenna interface is used to connect to the outdoor antenna; the switch module is respectively connected to the outdoor antenna interface, The second antenna and the control module, the switch module is connected to the control module and the outdoor antenna interface in response to the enhanced control signal, so that the control module converts the signal received by the outdoor antenna interface into an indoor enhanced signal and transmits it through the first antenna, and the switch module responds to the communication control The signal is connected to the control module and the second antenna, so that the control module controls the first antenna and the second antenna to send and receive communication signals.

Description

technical field [0001] The present disclosure relates to the technical field of terminal equipment, and in particular, to a radio frequency circuit and a control method thereof, a terminal equipment, and an amplifier system. Background technique [0002] Wireless communication devices usually receive downlink signals sent by base stations through antennas, but indoor base station signal coverage in residential homes, shops, offices, basements and elevators is weak, which affects wireless communication. [0003] At present, signal amplifiers are usually installed in weak signal coverage areas such as residential homes, shops, offices, basements, and elevators to enhance the signal to achieve signal coverage in weak signal coverage areas. However, the signal amplifier provided by the related art has the problems of large volume, high quality and poor portability. [0004] It should be noted that the information disclosed in the above background section is only for enhancing t...
