Abstract
In order to solve the problem that signals often interfere with one another in the RF front-end module in the prior art, the application provides an RF front-end module, an antenna device and a control method for the RF front-end module. The module comprises an antenna switch selection module, an RF signal transmitting link, a first RF signal receiving link and a second RF signal receiving link; the RF signal transmitting link, first RF signal receiving link and second RF signal receiving link are separately connected to a first inner peripheral port, second inner peripheral port and third inner peripheral port respectively. The antenna device and RF front-end module thereof improve the isolation effect. When the RF front-end circuit receives a plurality of RF signals at the same time, the isolation among different RF signals at the antenna switch selection module is higher than that in the prior art.
