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...
