Problems solved by technology

[0003] During the process of conceiving and implementing this application, the inventor found at least the following problems: For example, in 5G equipment, there are 4 antennas in the 5G N41 frequency band, and one or several N41 antennas are required to share the antenna with 5GN77 / N78 / N79. This common antenna solution needs to use a frequency divider of N41 and N77-N79, and the frequency divider is used to achieve frequency division. In signal processing, the insertion loss of the signal will be increased, resulting in a decrease in antenna performance.

[0082] The present application proposes a radio frequency front-end module, and the radio frequency front-end module can be applied to the mobile terminal in the foregoing embodiments.

[0083] Optionally, the mobile terminal can be a processor, a tablet, a smart wearable device, etc. The mobile terminal includes multiple radio frequency antennas and wireless antennas to realize the communication function of the mobile terminal, and the multiple radio frequency antennas also have a main set of radio frequency antennas and diversity RF antennas. Among them, the main antenna is responsible for the transmission and reception of radio frequency signals, and the diversity antenna only receives but not transmits. The main chip of the mobile terminal combines the signals received from the two antennas to obtain diversity gain. Mobile terminals usually support multiple network standards, such as 5G network standard (5GNR, fifth-generation mobile communication technology), LTE network ...
