Abstract: Embodiments of the present invention disclose a radio frequency front-end system, including a first antenna, a second antenna, a first radio frequency circuit, a second radio frequency circuit, and a control apparatus, where the control apparatus is configured to acquire a transmission frequency band selected by the first radio frequency circuit, and if a frequency in the transmission frequency band selected by the first radio frequency circuit is less than a preset frequency, control the first radio frequency circuit to connect to the second antenna, and disconnect a connection between the second radio frequency circuit and the second antenna, or maintain an open circuit state between the second radio frequency circuit and the second antenna. The embodiments of the present invention further disclose a signal transmission control method. A size of an antenna can be effectively reduced by using the present invention.
