The present disclosure relates to the field of charging technologies, and in particular to a radio frequency front-end module, an antenna system, and an electronic device.
With the development and advancement of technologies, the 5G communication technology has been widely used. The 5G communication is usually realized by using a 4G and 5G dual connectivity (EUTRA-NR Dual Connectivity, ENDC) technology. In the ENDC technology, a 4G base station serves as a master station and a 5G base station serves as a slave station, and a 5G network may be connected only after a 4G network is connected. That is, a radio frequency module in the electronic device needs to have both a 4G module and a 5G module. For example, the electronic device uses a combination of B3+N41 to enable the ENDC, where the electronic device is provided with a first power amplifier module for transmission at a B3 frequency band, and a second power amplifier module for transmission at a N41 frequency band. At present, the electronic devices gradually tend to be miniaturized and thinned, which leads to a limited space inside the electronic device. However, the first power amplifier module and the second power amplifier module would occupy a large space in the electronic device, which is not conducive to the arrangement of internal elements in the electronic device.

The 5G NSA (non-standalone) standard recently published by 3GPP adopts a mode of LTE and 5G NR (new radio) dual connectivity (ENDC). As illustrated in
In the LTE dual connectivity, a RRC protocol is established between the master station and the terminal, that is, the RRC message is only transmitted between the master station and the terminal. However, the master station and the slave station perform radio resource management (RRM) separately, and interaction and cooperation of the RRM functions are performed between the master station and the slave station through an X2 interface. For example, after the slave station allocates a resource, interaction is performed with the master station through the X2 interface, and the master station sends, to the terminal, an RRC message including the resource configured by the slave station. That is, as illustrated in
In the LTE-NR dual connectivity, not only the master station and the slave station perform the RRM separately, but also the RRC protocol is independently established between the master station and the terminal and between the slave station and the terminal. That is, as illustrated in
Firstly, an exemplary embodiment of the present disclosure provides a radio frequency front-end module. As illustrated in
In the radio frequency front-end module provided in the embodiments of the present disclosure, the first amplifier unit 210 receives and amplifies the signal at the first frequency band Bx, and the second amplifier unit 220 receives and amplifies the signal at the second frequency band Np. In the 4G and 5G dual connectivity mode, the signal at the second frequency band Np is transmitted to the second antenna interface 120 through the first switch unit 230, and the signal at the first frequency band Bx is transmitted to the first antenna interface 110 through the antenna switch module 240. In this way, the signal at the first frequency band Bx and the signal at the second frequency band Np can be simultaneously transmitted from one radio frequency module. In one aspect, the space for wiring inside an electronic device can be saved, which is conductive to the thinning of the electronic device. In another aspect, the cost of the electronic device can be reduced. In addition, in the case where the first switch unit 230 switches the signal at the second frequency band Np to the second antenna interface 120, an intermodulation distortion signal is avoided from being generated by the signal at the first frequency band Bx and the signal at the second frequency band Np.
The radio frequency front-end module provided in the embodiment of the present disclosure may be a power amplifier module. In the embodiments of the present disclosure, the first frequency band Bx may be B3, and the second frequency band Np may be N41. The first amplifier unit 210 may include a first power amplifier 211, and the second amplifier unit 220 may include a second power amplifier 221. The first amplifier unit 210 is connected with a first signal interface 310, and the signal at the B3 frequency is input to the first amplifier unit 210 through the first signal interface 310. The first amplifier unit 210 performs power amplification on the signal at the B3 frequency band. The second amplifier unit 220 is connected with a second signal interface 320, and the signal at the N41 frequency is input to the second amplifier unit 220 through the second signal interface 320. The second amplifier unit 220 performs power amplification on the signal at the N41 frequency band.
An uplink frequency range of the B3 frequency band is from 1710 MHz to 1785 MHz, a downlink frequency range of the B3 frequency band is from 1805 MHz to 1880 MHz, and the uplink and downlink frequency ranges of N41 are both from 2496 MHz to 2690 MHz. In a case where an uplink signal at the B3 frequency band and an uplink signal at the N41 frequency band pass through the antenna switch module 240, a 4-order intermodulation distortion (IMD4) signal is generated, and a frequency range of which is from 1422 MHz to 1960 MHz. The frequency range of the 4-order intermodulation distortion signal covers the downlink frequency range of the B3 frequency band, and thus the receiving sensitivity of the radio frequency module at the B3 frequency band is affected. In the embodiments of the present disclosure, when the uplink signal at the B3 frequency band is transmitted to the antenna switch module 240, the uplink signal at the N41 frequency band is switched to the second antenna interface 120 through the first switch unit 230, to avoid an intermodulation distortion signal that would otherwise be generated when the uplink signal at the B3 frequency band and the uplink signal at the N41 frequency band pass through the antenna switch module 240.
