According to one embodiment, the electronic device 101 may include a fourth RFIC 228 separately from or at least as part of the third RFIC 226. In this case, the fourth RFIC 228 converts the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz). After conversion, the IF signal can be transmitted to the third RFIC (226). The third RFIC 226 can convert the IF signal into a 5G Above6 RF signal. Upon reception, a 5G Above6 RF signal may be received from a second cellular network 294 (e.g., a 5G network) via an antenna (e.g., antenna 248) and converted into an IF signal by a third RFIC 226. there is. The fourth RFIC 228 may convert the IF signal into a baseband signal so that the second communication processor 214 can process it.

According to one embodiment, at least one antenna module of the first antenna module 242 or the second antenna module 244 may be omitted or combined with another antenna module to process RF signals of a plurality of corresponding bands.

According to one embodiment, the third RFIC 226 and the antenna 248 may be disposed on the same substrate to form the third antenna module 246. For example, the wireless communication module 192 or the processor 120 may be placed on the first substrate (eg, main PCB). In this case, the third RFIC 226 is located in some area (e.g., bottom surface) of the second substrate (e.g., sub PCB) separate from the first substrate, and the antenna 248 is located in another part (e.g., top surface). is disposed, so that the third antenna module 246 can be formed. By placing the third RFIC 226 and the antenna 248 on the same substrate, it is possible to reduce the length of the transmission line therebetween. This, for example, can reduce the loss (e.g. attenuation) of signals in the high frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communication by transmission lines. Because of this, the electronic device 101 can improve the quality or speed of communication with the second cellular network 294 (eg, 5G network).

In this case, the third RFIC 226 may include a plurality of phase shifters 238 corresponding to a plurality of antenna elements, for example, as part of the third RFFE 236. At the time of transmission, each of the plurality of phase converters 238 may convert the phase of the 5G Above6 RF signal to be transmitted to the outside of the electronic device 101 (e.g., a base station of a 5G network) through the corresponding antenna element. . Upon reception, each of the plurality of phase converters 238 may convert the phase of the 5G Above6 RF signal received from the outside through the corresponding antenna element into the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device 101 and the outside.

The second cellular network 294 (e.g., 5G network) may operate independently (e.g., Stand-Alone (SA)) or connected to the first cellular network 292 (e.g., legacy network) ( Example: Non-Stand Alone (NSA). For example, a 5G network may have only an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device 101 may access the access network of the 5G network and then access an external network (eg, the Internet) under the control of the core network (eg, 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) is stored in the memory 230 and stored in the memory 230, 120, first communication processor 212, or second communication processor 214).
