Abstract

The invention relates to the technical field of communication, and provides a radio frequency front-end module and a method and device for controlling the radio frequency front-end module, the device can be a terminal device, such as a tablet personal computer, a wearable device, a vehicle-mounted device and the like, and the radio frequency front-end module comprises a first switch module configured to switch a path of a first frequency band transmitting signal; the second switch module is configured to switch a path of a second frequency band transmitting signal and switch a path of a second frequency band diversity receiving signal; the first frequency division combiner is respectively coupled with the first switch module and the second switch module; and the second frequency division combiner is respectively coupled with the first switch module and the second switch module. According to the device, an LTE diversity channel is not interrupted when the LTE and the NR execute antenna switching at the same time.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a radio frequency front-end module, and a method and apparatus for controlling the radio frequency front-end module. Background technique [0002] With the development of mobile communication technology, the fifth generation mobile communication technology (5th generation wireless systems, 5G) has higher transmission efficiency and is therefore widely used. In the current 5G networking form, the non-standalone (NSA) method occupies a considerable proportion, and some operators use the long-term evolution (LTE) and 5G (new radio, NR) dual The NSA networking is carried out in the form of e-utran new radio-dual connectivity (ENDC). [0003] In the ENDC scenario, the frequency band of the 4th generation wireless systems (4G) can be used as the anchor frequency, mainly for data synchronization, and the 5G frequency band can be used for data transmission. With...
