The fourth RFIC228may be omitted or may be included as a part of the third RFIC226.

The first communication processor212may support establishment of a communication channel in a band to be used for wireless communication with the first cellular network292and legacy network communication through the established communication channel. According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long-term evolution (LTE) network. The second communication processor214may support establishment of a communication channel corresponding to a specified band (e.g., about 6 GHz to about 60 GHz) among the bands to be used for wireless communication with the second cellular network294, and 5G network communication through the established communication channel.

In the case of transmission, the first RFIC222may convert a baseband signal generated by the first communication processor212into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network292(e.g., a legacy network). In the case of reception, an RF signal may be obtained from the first cellular network292(e.g., a legacy network) through an antenna (e.g., the first antenna module242), and may be preprocessed through an RFFE (e.g., the first RFFE232). The first RFIC222may convert the preprocessed RF signal into a baseband signal to be processed by the first communication processor212.

In the case of transmission, the second RFIC224may convert a baseband signal generated by the first communication processor212or the second communication processor214into an RF signal in a Sub6 band (e.g., about 6 GHz or less) (hereinafter, a 5G Sub6 RF signal) to be used in the second cellular network294(e.g., a 5G network). In the case of reception, a 5G Sub6 RF signal may be obtained from the second cellular network294(e.g., a 5G network) through an antenna (e.g., the second antenna module244), and may be preprocessed through an RFFE (e.g., the second RFFE234).

In the case of reception, a 5G Above6 RF signal may be obtained from the second cellular network294(e.g., a 5G network) through an antenna (e.g., the antenna248) and may be preprocessed through the third RFFE236.

According to an embodiment, the third RFFE236may be configured as a part of the third RFIC226.

According to an embodiment, the electronic device101may include a fourth RFIC228separately from or as at least a part of the third RFIC226. In this case, the fourth RFIC228may convert a baseband signal generated by the second communication processor214into an RF signal in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) (hereinafter, IF signal) and transmit the IF signal to the third RFIC226. The third RFIC226may convert the IF signal into a 5G Above6 RF signal. In the case of reception, a 5G Above6 RF signal may be received from the second network294(e.g., a 5G network) through an antenna (e.g., the antenna248) and may be converted into an IF signal by the third RFIC226. The fourth RFIC228may convert the IF signal into a baseband signal to be processed by the second communication processor214.

According to an embodiment, the first RFIC222and the second RFIC224may be implemented as at least a part of a single chip or single package. According to an embodiment, the first RFFE232and the second RFFE234may be implemented as at least a part of a single chip or single package. According to an embodiment, at least one antenna module of the first antenna module242or the second antenna module244may be omitted or combined with another antenna module to process RF signals in a plurality of corresponding bands.

According to an embodiment, the third RFIC226and the antenna248may be disposed on the same substrate to configure a third antenna module246. For example, the wireless communication module192or the processor120may be disposed on the first substrate (e.g., a main PCB). In this case, the third RFIC226may be disposed in a partial area (e.g., the bottom surface) of a second substrate (e.g., a sub-PCB) that is separate from the first substrate, and the antenna248may be disposed in another partial area (e.g., the top surface) thereof, thereby configuring the third antenna module246. By disposing the third RFIC226and the antenna248on the same substrate, it is possible to reduce the length of a transmission line therebetween. This may reduce loss (e.g., attenuation) of a signal, for example, in a high-frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communication due to a transmission line. Accordingly, the electronic device101may improve the quality or speed of communication with the second cellular network294(e.g., a 5G network).

According to an embodiment, the antenna248may be configured as an antenna array including a plurality of antenna elements to be used in beamforming. In this case, the third RFIC226may include a plurality of phase shifters238corresponding to the plurality of antenna elements as, for example, a part of the third RFFE236. In the case of transmission, the each of the plurality of phase shifters238may convert the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device101(e.g., a base station of a 5G network) through a corresponding antenna element. In the case of reception, each of the plurality of phase shifters238may convert the phase of a 5G Above6 RF signal received from the outside through a corresponding antenna element into the same or substantially the same phase. This enables transmission or reception between the electronic device101and the outside through beamforming.

The second cellular network294(e.g., a 5G network) may be operated independently of (e.g., stand-alone (SA)) or may be operated while being connected to (e.g., non-stand-alone (NSA)) the first cellular network292(e.g., a legacy network). For example, the 5G network may have only an access network (e.g., a 5G radio access network (RAN) or a next-generation RAN (NG RAN)), and may not have a core network (e.g., a next-generation core (NGC)). In this case, after accessing the access network of the 5G network, the electronic device101may access an external network (e.g., the Internet) under the control of a core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information for communication with the legacy network (e.g., LTE protocol information) or protocol information for communication with the 5G network (e.g., new radio (NR) protocol information) may be stored in the memory130, and other components (e.g., the processor120, the first communication processor212, or the second communication processor214) may access the same.
