[0061] In one embodiment, the third RFIC (226) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, a 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second network (294) (e.g., a 5G network). Upon reception, the 5G Above6 RF signal may be acquired from the second network (294) (e.g., the 5G network) via an antenna (e.g., the antenna 248) and preprocessed via the third RFFE (236). The third RFIC (226) may convert the preprocessed 5G Above6 RF signal into a baseband signal so that it may be processed by the second communication processor (214). In one embodiment, the third RFFE (236) may be formed as a part of the third RFIC (226).
[0062] In one embodiment, the electronic device (100) may include a fourth RFIC (228) separate from or at least as part of the first RFIC (222), the second RFIC (224), or the third RFIC (226).
[0063] In one embodiment, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, referred to as an IF signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second network (294) (e.g., a 5G network) via an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) may convert the IF signal into a baseband signal so that the second communication processor (214) can process it.
[0064] In one embodiment, the first RFIC (222) and the second RFIC (224) may be implemented as a single chip or at least part of a single package.
[0065] In one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least part of a single chip or a single package.
[0066] In one embodiment, at least one antenna circuit of the first antenna circuit (242) and / or the second antenna circuit (244) may be omitted or combined with another antenna circuit to process RF signals of corresponding multiple bands.
[0067] For example, the first antenna circuit (242) and / or the second antenna circuit (244) may each include at least one antenna. However, the present invention is not limited thereto, and the first antenna circuit (242) may include at least one antenna and a matching circuit for impedance matching of the antennas. The second antenna circuit (244) may include at least one antenna and a matching circuit for impedance matching of the antennas.
[0068] In one embodiment, the third RFIC (226) and the antenna (248) may be disposed on the same substrate to form a third antenna module (246). For example, the communication circuitry (160) or the processor (110) may be disposed on the first substrate (e.g., the main PCB).
[0069] In one embodiment, a third RFIC (226) may be disposed on a portion (e.g., a lower surface) of a first substrate and a separate second substrate (e.g., a sub PCB), and an antenna (248) may be disposed on another portion (e.g., a top surface) of a third antenna module (246). By disposing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of a transmission line therebetween. For example, it is possible to reduce loss (e.g., attenuation) of signals in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication due to the transmission line. As a result, the electronic device (100) may improve the quality or speed of communication with the second network (294) (e.g., a 5G network).
[0070] In one embodiment, the antenna (248) may be formed as an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal to be transmitted to an external source (e.g., a base station of a 5G network) of the electronic device (100) via its corresponding antenna element. Upon reception, each of the plurality of phase shifters (238) may shift the phase of a 5G Above6 RF signal received from the external source via its corresponding antenna element to the same or substantially the same phase. This enables transmission or reception via beamforming between the electronic device (100) and the external source.
[0071] In one embodiment, the second network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or in conjunction with (e.g., Non-Stand Alone (NSA)) the first network (292) (e.g., a legacy network). For example, the 5G network may only have an access network (e.g., a 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). After accessing the access network of the 5G network, the electronic device (100) may access an external network (e.g., the Internet) under the control of the core network (e.g., evolved packed core (EPC)) of the legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) may be stored in the memory (230) and accessed by other components (e.g., the processor (110), the first communication processor (212), or the second communication processor (214)).
