The embodiment of the invention discloses a radio frequency front-end circuit, a control method and terminal equipment, relates to the technical field of communication, and solves the problem that the dual-card communication quality is affected due to hardware resource conflicts when dual-card services of the terminal equipment are concurrent. According to the specific scheme, the radio frequency front-end circuit comprising a filter circuit, a first selection circuit and a second selection circuit is provided, and the selection end of the first selection circuit and the selection end of the second selection circuit are both used for being coupled with a first antenna or a second antenna. The filter circuit is used for filtering and sending the first radio frequency signal and the second radio frequency signal. The first selection circuit is used for receiving a first control signal and a first radio frequency signal, and gating one of the first antenna and the second antenna to send the first radio frequency
