The communication module 190 can include one or more communication processors that operate independently of the processor 120 (e.g., an application processor) and support the direct (e.g., wired) or wireless communication. According to an embodiment, the communication module 190 can include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module, or a power line communication module). Among these communication modules, the corresponding communication modules can communicate with the external electronic device 104 via a first network 198 (e.g., a short-range communication network such as Bluetooth, WiFi (Wireless Fidelity) Direct, or IrDA (infrared data association)) or a second network 199 (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). Such several types of communication modules may be integrated into one component (e.g., a single chip) or may be implemented in multiple components (e.g., multiple chips) that are separate from each other. The wireless communication module 192 can use the subscriber information (e.g., International Mobile Subscriber Identity (IMSI)) stored in the subscriber identification module 196 to identify or authenticate the electronic device 101 in a communication network such as the first network 198 or the second network 199.

[0036] The wireless communication module 192 can support 5G networks and next-generation communication technologies after 4G networks, such as new radio access technology (NR). The NR connection technology can support high-capacity data high-speed transmission (eMBB (enhanced mobile broadband)), terminal power minimization and multi-terminal connection (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module 192 can support high frequency bands (e.g., mmWave bands) to achieve high data rates. The wireless communication module 192 can support various technologies for ensuring performance in high frequency bands, such as beamforming, massive MIMO (multiple-input and multiple-output), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

[0039] At least some of the components are connected to each other via a peripheral communication method (e.g., a bus, a general purpose input and output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)) and can exchange signals (e.g., commands or data) with each other.

[0040] According to an embodiment, instructions or data can be sent or received between the electronic device 101 and the external electronic device 104 via a server 108 connected to a second network 199.

According to an embodiment, all or part of the operations performed by the electronic device 101 can be performed by one or more of the external electronic devices 102, 104, or 108. For example, if the electronic device 101 needs to perform some function or service automatically or upon request from a user or other device, the electronic device 101 can request one or more external electronic devices to perform the function or at least part of the service instead of performing the function or service itself or additionally.

According to one embodiment, the third RFFE 236 may be formed as part of the third RFIC 226 .

[0047] According to an embodiment, the electronic device 101 may include a fourth RFIC 228 separately from or at least as a part of the third RFIC 226. In this case, the fourth RFIC 228 may convert the baseband signal generated by the second communication processor 214 into an RF signal (hereinafter, IF (intermediate frequency) signal) in 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 Above 6 RF signal. On reception, the 5G Above 6 RF signal may be received from the second cellular 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.

[0048] According to an embodiment, the first RFIC 222 and the second RFIC 224 may be implemented as at least part of a single chip or a single package. According to an 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. According to an embodiment, at least one 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 corresponding multiple bands.

[0049] According to an 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 wireless communication module 192 or the processor 120 may be disposed on a first substrate (e.g., a main PCB). In this case, the third RFIC 226 may be disposed on a portion of a second substrate (e.g., a sub-PCB) different from the first substrate, and the antenna 248 may be disposed on another portion of the second substrate (e.g., a sub-PCB), to form the third antenna module 246. According to an embodiment, the antenna 248 may include, for example, an antenna array that may be used for beam forming. By disposing the third RFIC 226 and the antenna 248 on the same substrate, the length of the transmission line between them may be shortened. This may reduce the loss (e.g., attenuation) of a signal in a high frequency band (e.g., about 6 GHz to about 60 GHz) used in 5G network communication by the transmission line. This allows the electronic device 101 to improve the quality or speed of communication with the second cellular network 294 (e.g., a 5G network).

[0050] The second cellular network 294 (e.g., a 5G network) may operate independently (e.g., Stand Alone (SA)) or in connection (e.g., Non-Stand Alone (NSA)) with the first cellular 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 a next generation RAN (NG RAN)), and may not have a core network (e.g., a next generation core (NGC)). In this case, the electronic device 101 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 after accessing the access network of the 5G network. Protocol information for communicating with a legacy network (e.g., LTE protocol information) or protocol information for communicating with a 5G network (e.g., New Radio (NR) protocol information) may be stored in memory 230 and accessed by other components (e.g., processor 120, first communication processor 212, or second communication processor 214).

[0051] 3 is a diagram illustrating a wireless communication system for providing a network for legacy communication and / or 5G communication according to an embodiment. FIG. 3 illustrates a first base station 310, a second base station 330, and an electronic device 101 as part of nodes using wireless channels in the wireless communication system.

[0052] Referring to FIG. 3, each of the first base station 310 and the second base station 330 may be a network infrastructure that provides wireless connectivity to the electronic device 101. Each of the first base station 310 and the second base station 330 may have a coverage, which is a geographical area defined based on the distance over which a signal can be transmitted. The "coverage" described below may refer to a service coverage area in which the service of the base station is available. Each base station may cover one cell or multiple cells. Here, the multiple cells may be distinguished by the frequency supported by the base station or the area of ​​the sector covered by the base station.

[0053] The first base station 310 may be referred to as an "access point (AP)", "eNodeB (eNB)", "wireless point", "transmission / reception point (TRP)", "distributed unit (DU)", "radio unit (RU)", "remote radio head (RRH)", or other terms having equivalent technical meanings, in addition to a base station. According to an embodiment, the first base station 310 may provide a first communication technology (e.g., LTE) as a radio access technology (RAT). According to an embodiment, the first base station 310 may operate as an eNB to support an E-UTRA (revolved, universal, terrestrial, radioaccess) carrier in an EN-DC. In one example, the electronic device 101 may transmit and receive radio signals to and from the first base station 310 within a frequency band of about 800 MHz to about 2.6 GHz.

[0054] The second base station 330 may be referred to as a "5th generation node", "5G NodeB (NB)", "gNB (next generation node B)", "wireless point", "transmission / reception point (TRP)", "central unit (CU)", "distributed unit (DU)", "radio unit (RU)", "remote radio head (RRH)", or other terms having equivalent technical meanings, in addition to a base station. According to an embodiment, the second base station 330 may be connected to one or more "transmission / reception points (TRP)". The second base station 330 may transmit a downlink signal to the electronic device 101 or receive an uplink signal from the electronic device 101 via one or more TRPs. According to an embodiment, the second base station 330 may provide a second communication technology (e.g., NR) as a radio access technology (RAT). According to an embodiment, the second base station 330 can operate as a gNB to support an NR carrier in the EN-DC. In one example, the electronic device 101 can transmit and receive radio signals in a frequency band of a first frequency range (e.g., NR FR1: about 410 MHz (megahertz) to about 7125 MHz) or a second frequency range (e.g., NR FR2: about 24250 MHz to about 52600 MHz, or about 24250 MHz to about 100000 MHz).

[0055] Although not shown in FIG. 3, in a 5G system, a base station may be implemented in a distributed deployment to support virtualization of network functions or more efficient resource management and scheduling. For example, in a 5G system, a base station gNB may be further divided into a central unit (CU) and a distributed unit (DU). For example, the CU may have at least a radio resource control (RRC) and a packet data convergence protocol (PDCP) protocol layer. According to an embodiment, the CU may further include a service data adaptation protocol (SDAP). For example, the DU may have a radio link control (RLC), a medium access control (MAC), and a physical layer. For example, an F1 interface, which is a standardized public interface, may exist between the CU and the DU. The F1 interface may be partitioned into a control plane F1-C and a user plane F1-U. The transmission network layer of the F1-C may be based on IP transmission. For more robust signaling, the stream control transmission protocol (SCTP) protocol can be added on top of the internet protocol (IP). The application layer protocol can be F1AP. SCTP can provide robust application layer messaging. The transmission layer of F1-U can be user datagram protocol (UDP) / IP. GPRS (general packet radio service) tunnelling protocol (GTP)-U can be used on top of UDP / IP to carry user plane protocol data units (PDUs).

[0056] The electronic devices 101 are devices used by a user and can communicate with the first base station 310 and / or the second base station 330 via a wireless channel. In some cases, the electronic devices 101 can operate without the involvement of a user. That is, at least one of the electronic devices 101 is a device for performing Machine Type Communication (MTC) and may not be carried by a user. In addition to a terminal, the electronic devices 101 may be referred to as a "user equipment (UE)", a "mobile station", a "subscriber station", a "customer premises equipment (CPE)", a "remote terminal", a "wireless terminal", an "electronic device", a "vehicle terminal", a "user device", or other terms having equivalent technical meanings.

[0057] According to an embodiment, the electronic device 101 can be connected to the first base station 310 and the second base station 330 via dual connectivity (DC) 350. One (a) of the first base station 310 and the second base station 330 can operate as a master node (MN), and the other of the first base station 310 and the second base station 330 can operate as a secondary node (SN). The MN and the SN can be connected via a network interface (e.g., an X2 interface, an XN interface).

[0058] Although not shown in FIG. 3, the first base station 310 or the second base station 330 may be connected to an evolved packet core (EPC) network, which is the core of a 4G network. When the first base station 310 provides a primary cell group and the second base station 330 provides a secondary cell group, the connection between the two base stations may be referred to as evolved universal terrestrial radio access-new radio dual-connectivity (EN-DC). Through the EN-DC, a terminal can connect to an LTE cell using LTE technology and to an NR cell using NR technology. Hereinafter, a cell using LTE technology may be referred to as an LTE cell, an E-UTRA cell, or a 4G cell, and a frequency of a cell using LTE technology may be referred to as an E-UTRA carrier, an LTE carrier, or a 4G carrier. Hereinafter, a cell using NR technology may be referred to as an NR cell or a 5G cell, and a frequency of a cell using NR technology may be referred to as an NR carrier or a 5G carrier.

[0059] In the following, in various embodiments of the present disclosure, EN-DC will be described as an example of a technique for providing both LTE carriers and NR carriers, but the embodiments of the present disclosure are not limited thereto. The same principle of the embodiments described below can also be applied to different types of DC (e.g., NE-DC (new radio-Evolved universal terrestrial radio access dual-connectivity), NGEN-DC (NG-RAN (next generation-radio access network) evolved universal terrestrial radio access-new radio dual-connectivity)).

[0060] The possible DC types can be defined as follows:

[0061] [Table 1]

[0062] The electronic device 101 may support MR (multi-radio)-DC. The electronic device 101 may be connected to a first base station 310 and a second base station 320. The first base station 310 may be an MN, and the second base station 320 may be an SN and may be connected to a terminal. With carrier aggregation (CA) provided by each base station, the dual connection may provide a higher data rate. The first base station 310 and the second base station 320 may transmit downlink traffic to the electronic device 101 or receive uplink traffic from the electronic device 101 as an MN and an SN, respectively. FIG. 4a is a simplified block diagram of an exemplary electronic device according to an embodiment. FIG. 4b is a simplified block diagram of an exemplary electronic device including an FEM including a switch. FIG. 5 illustrates an example of the structure of one FEM in an electronic device according to an embodiment. FIG. 6 illustrates an example of the structure of another FEM in an electronic device according to an embodiment. 7 and 8 show an example of a connection relationship between a PA of one FEM and a terminal of one FEM in an electronic device according to an embodiment.

[0063] Referring to Figures 4a, 4b, 5, 6, 7 and 8, the electronic device 101 may include a processor 400, a first power supply circuit 401, a second power supply circuit 402, a first FEM 410, a second FEM 420, a third FEM 430, a fourth FEM 440, a fifth FEM 450, and / or a sixth FEM 460.

[0064] In one embodiment, the processor 400 may include the processor 120 shown in Figure 1.

Each FEM 410, 420, 430, 440, 450, 460 may be connected to one of the antennas A1, A2, A3, A4, A5, A6. According to one embodiment, some of the antennas A1, A2, A3, A4, A5, A6 may be connected to one or more FEMs. For example, each of the FEMs 410, 420, 430, 440, 450, 460 may include at least one filter (e.g., the first filter 521, the second filter 531, or the third filter 541), at least one power amplifier (PA) (e.g., the first PA 411, the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461), a switch (e.g., the switch 550 and / or the switch 580), or a duplexer (e.g., the first duplexer 520, the second duplexer 530, or the third duplexer 540) for processing the signal transmitted via one of the antennas A1, A2, A3, A4, A5, A6. Each of the FEMs 410, 420, 430, 440, 450, 460 may process signals having different frequencies from each other. For example, a first frequency band of a first signal processed by the first FEM 410 and transmitted via an antenna A (e.g., at least one of antennas A1, A2, A3, A4, A5, A6) may be separated from a second frequency band of a second signal processed by the second FEM 420 and transmitted via an antenna. A first frequency band of a first signal processed by the first FEM 410 and transmitted via an antenna may overlap with a third frequency band of a third signal processed by the third FEM 430 and transmitted via an antenna. However, this is not limited thereto. Voltages for the operating ranges of the PAs 411, 421, 431, 441, 451, 461 may be set by the processor 400.According to one embodiment, the voltage may be set by at least one radio frequency integrated circuit (RFIC) (not shown) connected to the processor 400 and each FEM, where the FEM may be referred to as a radio frequency chain or an RF path.

For example, antenna A may include at least one array antenna including each of a plurality of antennas. According to one embodiment, antenna A may include an antenna utilizing a conductive portion disposed along at least a portion of a side of a housing of electronic device 101. According to one embodiment, antenna A may include a plurality of antennas, and the plurality of antennas may correspond to each FEM. However, without being limited thereto, the number of the plurality of antennas and the number of FEMs may be different. For example, third FEM 430 and fourth FEM 440 may be connected to one antenna, and the one antenna connected to third FEM 430 and fourth FEM 440 may be an antenna shared for third FEM 430 and fourth FEM 440. The fifth FEM 450 and the sixth FEM 460 may be connected to one other antenna, and the other one antenna connected to the fifth FEM 450 and the sixth FEM 460 may be an antenna shared for the fifth FEM 450 and the sixth FEM 460. According to one embodiment, six FEMs are described as being arranged, but the number of FEMs may be less than six or more than six. For example, the multiple FEMs may include a first FEM 410, a second FEM 420, a third FEM 430, and / or a fourth FEM 440. The FEMs may be configured to transmit different RF signals to the outside. For example, the first FEM 410 may include a first PA 411 configured to transmit a first RF signal of a first frequency. The first PA 411 may be configured to amplify the first RF signal based on a voltage Vcc1 of the first power supply circuit 401.

The third PA 431 may be configured to amplify the third RF signal based on a voltage Vcc1 of the first power supply circuit 401 and / or a voltage Vcc2 of the second power supply circuit 402 communicated via a switch 490. The fourth FEM 440 may include a fourth PA 441 configured to transmit a fourth RF signal at a fourth frequency distinct from the first RF signal, the second RF signal, and the third RF signal. The fourth PA 441 may be configured to amplify the fourth RF signal based on a voltage Vcc1 of the first power supply circuit 401 and / or a voltage Vcc2 of the second power supply circuit 402 communicated via a switch 490.

The third PA 431 , the fourth PA 441 , the fifth PA 451 , and / or the sixth PA 461 may be connected to a switch 490 .

[0067] 4a may be external to the third FEM 430, the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460. The switch 490 is connected to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461, and may supply the voltage of the first power supply circuit 401 and / or the voltage of the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. The switch 490 is connected to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461, and can supply power from the first power supply circuit 401 and / or power from the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. The switch 490 in FIG. 4b can be disposed in one FEM (e.g., the third FEM 430 in FIG. 4b) of the third FEM 430, the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460. The third FEM 430 can include the switch 490. At least one power supply circuit (e.g., the first power supply circuit 401 or the second power supply circuit 402) can variably supply the voltage to the PA based on the control of the processor 400 and / or a radio frequency integrated circuit (RFIC) (not shown). According to an embodiment, the voltage for the dynamic range of the PAs 411, 421, 431, 441, 451, 461 can be set by the processor 400. The voltage can be set by a radio frequency integrated circuit (RFIC) (not shown) connected to the processor 400 and each FEM 410, 420, 430, 440, 450, 460. For example, the RFIC can set the voltage via the at least one power supply circuit 401, 402 based on envelope tracking (ET). However, this is not limiting. At least one power supply circuit 401, 402 can variably supply the voltage to PAs 411, 421, 431, 441, 451, 461 under control of a processor 400 and / or the RFIC.For example, at least one power supply circuit 401, 402 may be used to set the voltage based on ET. According to one embodiment, at least one power supply circuit 401, 402 may be used to set the voltage based on average power tracking (APT). At least one power supply circuit 401, 402 has been described as providing a voltage, but may provide power to PAs 411, 421, 431, 441, 451, 461. The at least one power supply circuit 401, 402 may also be referred to as a modulator, ET modulator, supply modulator, power supply, power supply, or voltage supply circuit.

[0068] According to an embodiment, at least one power supply circuit may include a first power supply circuit 401 and / or a second power supply circuit 402. For example, each of the PAs 431, 441, 451, 461 included in each of some of the FEMs 430, 440, 450, 460 may be supplied with a voltage or power from the first power supply circuit 401 or the second power supply circuit 402. For example, a first PA 411 included in a first FEM 410 of the FEMs may be supplied with a first voltage Vcc1 or power from the first power supply circuit 401. For example, a second PA 421 included in a second FEM 420 of the FEMs may be supplied with a second voltage Vcc2 or power from the second power supply circuit 402. For example, the first power supply circuit 401 can be configured to supply a first voltage Vcc1 to the PAs 411, 431, 441, 451, 461 included in the first FEM 410, the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460, respectively. According to an embodiment, the first voltages Vcc1 transmitted from the first power supply circuit 401 to the PAs 411, 431, 441, 451, 461 may not be equal. For example, the voltage applied to the fourth PA 441, the fifth PA 451, or the sixth PA 461 from the first power supply circuit 401 via the switch 490 or the third FEM 430 may be smaller than the voltage applied to the third PA 431 due to a voltage drop. The second power supply circuit 402 can be configured to supply a second voltage Vcc2 to the PAs 421, 431, 441, 451, and 461 included in the second FEM 420, the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460, respectively. According to an embodiment, the second voltage Vcc2 transmitted from the second power supply circuit 402 to the PAs 421, 431, 441, 451, and 461 may not be equal. For example, the voltage applied to the fourth PA 441, the fifth PA 451, or the sixth PA 461 from the second power supply circuit via the third FEM 440 or the switch 490 may be smaller than the voltage applied to the third PA 431 transmitted from the second power supply circuit 402 due to a voltage drop.The first PA 411 of the first FEM 410 may be supplied with a first voltage Vcc1 via the first power supply circuit 401. The first PA 411 may receive power from the first power supply circuit 401. The second PA 421 of the second FEM 420 may be supplied with a second voltage Vcc2 via the second power supply circuit 402. The second PA 412 may receive power from the second power supply circuit 401. Each of the PAs 431, 441, 451, 461 of the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460 may be supplied with the first voltage Vcc1 or the second voltage Vcc2 via the first power supply circuit 401 or the second power supply circuit 402. Each of the PAs 431 , 441 , 451 , 461 can receive power from either the first power supply circuit 401 or the second power supply circuit 402 .

[0069] In one embodiment, the processor 400 can be configured to operate one PA (e.g., the first PA 411) of the PAs 411, 431, 441, 451, 461 in the FEMs 410, 430, 440, 450, 460 that is supplied with a first voltage Vcc1 from a first power supply circuit 401, and to operate a PA in one of the FEMs 420, 430, 440, 450, 460 that is supplied with a second voltage Vcc2 from a second power supply circuit 402, different from the PA (e.g., the first PA 411) in the FEM (e.g., the first FEM 410) in the FEM (410, 430, 440, 450, 460) that is supplied with the first voltage Vcc1.

[0070] According to one embodiment, the switch 490 can be operatively connected to the processor 400 to supply a first voltage Vcc1 provided by the first power supply circuit 401 and a second voltage Vcc2 provided by the second power supply circuit 402 to a designated FEM. The processor 400 can include at least one of the processor 120, the first communication processor 212 shown in FIG. 2, the second communication processor 214, the first RFIC 222, the second RFIC 224, the third RFIC 226, the fourth RFIC 228, or a transceiver. The switch 490 can be controlled by the processor 400. The switch 490 can selectively connect the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460 to the first power supply circuit 401 or the second power supply circuit 402. For example, the switch 490 can be configured to route a selected one of the first voltage Vcc1 (or a control signal) output by the first power supply circuit 401 and the second voltage Vcc2 (or a control signal) output by the second power supply circuit 402 to a signal path for providing to the third FEM 430, in response to the control of the processor 400. The first power supply circuit 401 is always electrically connected to the first FEM 410, and can be selectively connected to the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460 via a path 491 connected to the switch 490 and the switch 490. The second power supply circuit 402 is always electrically connected to the second FEM 420, and can be selectively connected to the third FEM 430, the fourth FEM 440, the fifth FEM 450, and the sixth FEM 460 via a path 492 connected to the switch 490 and the switch 490.

[0071] The switch 490 may include a first terminal 490a connected to each of the third PA 431 and the fourth PA 441, a second terminal 490b connected to the first power supply circuit 401, and a third terminal 490c connected to the second power supply circuit 402. While transmitting a signal using the second PA 421, the switch 490 may connect the first terminal 490a to the second terminal 490b to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461 based on a voltage from the first power supply circuit 401. The second PA 421 may operate based on a voltage from the second power supply circuit 402. While transmitting a signal using the first PA 411, the switch 490 can connect the first terminal 490a to the third terminal 490c to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451 and / or the sixth PA 461 based on the voltage from the second power supply circuit 401. The switch 490 may be referred to as a routing component in that it establishes one path out of several paths.

[0072] According to an embodiment, the processor 400 can be configured to provide a first connection state and a second connection state between the power supply circuits 401, 402 and the PAs 411, 421, 431, 441, 451, 461 via a switch 490. The first connection state may be a state in which the second power supply circuit 402 is electrically connected to the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 via the switch 490 to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, or the sixth PA 461 operating based on a second voltage Vcc2 supplied from the second power supply circuit 402 based on transmitting a signal using the first PA 411 operating based on a first voltage Vcc1 supplied from the first power supply circuit 401.

[0073] Within the first connection state, the processor 400 may be configured to cause the switch 490 to control a connection between the second power circuit 402 and the third PA 431 to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. The processor 400 may be configured to provide a control signal to the third FEM 430 that causes the switch 490 to connect the second power circuit 402 and the third PA 431 to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. The third PA 431 may be connected to the fourth PA 441, the fifth PA 451, and / or the sixth PA 461 via an electrical path. In order to transmit a signal using the first PA411, while the first PA411 obtains a first voltage Vcc1 supplied from the first power supply circuit 401, the third PA431, the fourth PA441, the fifth PA451, and / or the sixth PA461 can operate based on a second voltage Vcc2 supplied from the second power supply circuit 402.

[0074] The second connection state may be a state in which the first power supply circuit 401 is electrically connected to the third PA431, the fourth PA441, the fifth PA451 and the sixth PA461 via the switch 490 in order to transmit a signal using the third PA431, the fourth PA441, the fifth PA451 or the sixth PA461 operating based on the first voltage Vcc1 supplied from the first power supply circuit 401 based on transmitting a signal using the second PA421 operating based on the second voltage Vcc2 supplied from the second power supply circuit 402.

[0075] Within the second connection state, the processor 400 may be configured to cause the switch 490 to control a connection between the first power circuit 401 and the third PA 431 to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. The processor 400 may be configured to provide a control signal to the third FEM 430 that causes the switch 490 to connect the first power circuit 402 and the third PA 431 to transmit a signal using the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461. In order to transmit a signal using the second PA421, the third PA431, the fourth PA441, the fifth PA451, and / or the sixth PA461 can operate based on the first voltage Vcc1 supplied from the first power supply circuit 401 while the second PA421 obtains the second voltage Vcc2 supplied from the second power supply circuit 402.

[0076] The processor 400 may be configured to simultaneously transmit the selected one of the third RF signal to the sixth RF signal and the first RF signal in the first connection state, and the processor 400 may be configured to simultaneously transmit the selected one of the third RF signal to the sixth RF signal and the second RF signal in the second connection state.

[0077] According to one embodiment, the processor 400 can supply voltage to one PA via a first power supply circuit 401 while providing voltage to other PAs other than the one PA via a second power supply circuit 402.

[0078] According to one embodiment, the processor 400 can use the first PA 411 to transmit a signal to an external electronic device, and can use one of the following PAs to transmit a signal to another external electronic device that is distinct from the external electronic device: the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, or the sixth PA 461. However, without being limited thereto, the processor 400 can use the first PA 411 to transmit a signal to an external electronic device, and can use multiple PAs to transmit a signal to another external electronic device that is distinct from the external electronic device: the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, or the sixth PA 461. For example, while the processor 400 transmits a signal via an antenna using the first PA 411 operating based on the first voltage Vcc1 supplied from the first power supply circuit 401, the processor 400 can supply the second voltage Vcc2 supplied from the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461 via the switch 490. For example, while the processor 400 transmits a signal via the first antenna A1 to the outside using the first PA 411, the processor 400 can configure the switch 490 to refrain from electrically connecting the first power supply circuit 401 to the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461, and to electrically connect the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461. For example, the processor 400 can communicate with an external electronic device via an antenna A3, A4, A5, or A6 connected to one of the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461, which are supplied with the second voltage Vcc2 from the second power supply circuit 402.

[0079] According to an embodiment, the processor 400 may deactivate the remaining PAs among the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 supplied with the second voltage Vcc2, except for one PA that communicates with an external electronic device. For example, the PAs 431, 441, 451, and 461 that are supplied with the voltage via the switch 490 and do not transmit a signal may be disabled. The processor 400 may identify one PA among the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 that communicates with an external electronic device. Based on identifying that the one PA is the third PA 431, the processor 400 may send a signal to the fourth PA 441, the fifth PA 451, and the sixth PA 461 to request deactivation.

[0080] According to one embodiment, based on the above-mentioned operations, the processor 400 can electrically connect the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451 and the sixth PA 461 via the switch 490 in order to transmit a signal using one of the third PA 431, the fourth PA 441, the fifth PA 451 and the sixth PA 461 operating based on the second voltage Vcc2 supplied from the second power supply circuit 402 based on transmitting a signal using the first PA 411 operating based on the first voltage Vcc1 provided from the first power supply circuit 401. In another example, the processor 400 may be configured to electrically connect the first power supply circuit 401 to the third PA 431, the fourth PA 441, the fifth PA 451 or the sixth PA 461 via the switch 490 in order to transmit a signal using one of the third PA 431, the fourth PA 441, the fifth PA 451 or the sixth PA 461 operating based on a first voltage supplied from the first power supply circuit 401 based on transmitting a signal using the second PA 421 operating based on a voltage supplied from the second power supply circuit 402.

[0081] According to an embodiment, the processor 400 may be configured to receive a control message from a first external electronic device (e.g., the first base station 310 in FIG. 3) using the first PA 411 while a signal is being transmitted to the first external electronic device. The control message may be an RRC message. The control message may include information about a second external electronic device (e.g., the second base station 330 in FIG. 3) requesting an additional connection with the electronic device 101 and / or a frequency band for the connection.

[0082] According to an embodiment, the processor 400 may be configured to identify, based on the control message, a PA for a signal transmitted during the transmission of the signal using the first PA 411 from among the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461. The processor 400 may identify, based on information in the control message, a frequency band for a signal transmitted during the transmission of the signal using the first PA 411, and identify, based on the frequency band, a FEM, a PA, and / or an antenna for the transmitted signal.

[0083] According to an embodiment, the processor 400 may be configured to electrically connect the second power circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 via the switch 490 under a condition where the identified PA is identified as the third PA 431, the fourth PA 441, the fifth PA 451, or the sixth PA 461. For example, when the identified PA is the third PA 431, the processor 400 may be configured to electrically connect the second power circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 via the switch 490. The switch 490 may be configured to electrically connect the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 to the first power circuit 401 or the second power circuit 402. When the first power supply circuit 401 is electrically connected to the third PA431, the fourth PA441, the fifth PA451 and the sixth PA461, the second power supply circuit 402 may be electrically disconnected from the third PA431, the fourth PA441, the fifth PA451 and the sixth PA461.

[0084] According to one embodiment, the signal transmitted using the first PA 411 may be transmitted to the first external electronic device (e.g., the first base station 310 in FIG. 3) according to a first communication technology (e.g., LTE). The signal transmitted using the identified PA among the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, and the sixth PA 461 may be transmitted to a second external electronic device (e.g., the second base station 330 in FIG. 3) distinct from the first external electronic device (e.g., the first base station 310 in FIG. 3) according to another second communication technology (e.g., NR) different from the first communication technology. For example, the processor 400 may be configured to electrically connect the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461 via the switch 490 based on identifying, based on the control message, that the PA for the signal transmitted to the second external electronic device according to the second communication technology is the third PA 431.

As another example, the processor 400 may be configured to refrain from electrically connecting the second power supply circuit 402 to the third PA 431, the fourth PA 441, the fifth PA 451 and the sixth PA 461 via the switch 490 based on identifying, based on the control message, that the PA for the signal transmitted to the external electronic device according to the second communication technology is the second PA 421.

[0085] According to an embodiment, the processor 400 may be configured to receive a control message from a first external electronic device while a signal is being transmitted to the first external electronic device using the second PA 421, identify a PA for a signal to be transmitted while the signal is being transmitted using the second PA 421 from among the first PA 411, the third PA 431, the fourth PA 441, the fifth PA 451 and the sixth PA 461 based on the control message, and electrically connect the first power supply circuit 401 to the third PA 431, the fourth PA 441, the fifth PA 451 and the sixth PA 461 via the switch under a condition that the identified PA is identified as the third PA 431, the fourth PA 441, the fifth PA 451 or the sixth PA 461. The signal transmitted using the second PA 421 may be transmitted to the first external electronic device according to a first communication technology.

[0087] According to an embodiment, the processor 400 can provide a voltage to the first PA 411 via the first power supply circuit 401 and control the second PA 421, the fourth PA 441, the fifth PA 451, and the sixth PA 461 to refrain from operation based on identifying that the PA identified based on the control message is the third PA 431 while transmitting a signal to an external electronic device via the first PA 411. According to an embodiment, the processor 400 can provide a second voltage to the second PA 421 via the second power supply circuit 401 and control the first PA 411, the fourth PA 441, the fifth PA 451, and the sixth PA 461 to refrain from operation based on identifying that the PA identified based on the control message is the third PA 431 while transmitting a signal to an external electronic device via the second PA 421.

[0088] According to the above-described embodiment, instead of including a power switch 490 in each of the components (e.g., the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460) to be powered by the first power supply circuit 401 and the second power supply circuit 402, the switch 490 may be disposed external to the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460. The switch 490 disposed outside the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460 can electrically connect the first power supply circuit 401 to the third FEM 430, the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460, or can electrically connect the second power supply circuit 402 to the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460. As described above, the switch 490 can secure antenna freedom to support various frequency bands by electrically connecting the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460 to the first power supply circuit 401 or the second power supply circuit 402.

The switch 490 may be referred to as a routing component in that it establishes one path out of several paths.

[0100] According to one embodiment, the first terminal 720 may be configured to provide a first voltage Vcc1 provided by the first power supply circuit 401 to the PA 710 (e.g., the third PA 431 in FIG. 4b). The first switch 750 may provide an electrical connection 751 connected from the first terminal 720 to the PA 710. The first terminal 720 may be electrically connected to a first power supply circuit 401 external to the FEM 700 configured to provide a first voltage Vcc1 for operating the PA 710 within an operating range. A terminal may be referred to as a node in that it is disposed between two or more circuit elements (e.g., a switch, a PA, or an FEM). For example, the first terminal 720 may be referred to as a first node in that it is disposed between the first PA 411 and the PA 710 (e.g., the third PA 431 in FIG. 4b). The second terminal 730 may be referred to as a second node in that it is disposed between the second PA 421 and the PA 710. The third terminal 740 may be referred to as a third node in that it is disposed between the first switch 750 (or PA 710) and the fourth PA 441. A terminal may be referred to as a connection element or connector (e.g., a pad) in that it connects other circuit elements. The first terminal 720 and the second terminal 730 may be referred to as input terminals in that they are supplied with a voltage or power. The third terminal 740 may be referred to as an output terminal in that it transmits a voltage or power to the outside. According to one embodiment, the second terminal 730 may be configured to provide a second voltage Vcc2 provided from the second power supply circuit 402. The first switch 750 may provide a second electrical connection 752 connected from the second terminal 730 to the PA 710. The second terminal 730 may be electrically connected to a second power supply circuit 402 outside the FEM 700 configured to provide a second voltage Vcc2 for operating the PA 710 within an operating range.

[0101] According to one embodiment, the third terminal 740 can be electrically connected to the PA 710 in the FEM 700. According to one embodiment, the third terminal 740 can be electrically connected to a PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461 in FIG. 4b) in another FEM (e.g., the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460 in FIG. 4b) outside the FEM 700 (e.g., the third FEM 430 in FIG. 4b). The third terminal 740 can provide a third electrical connection 753 connected to the node N or the first switch 750 between the first terminal 720 and the second terminal 730 and the PA 710 to the outside. The third electrical connection 753 can be a path for supplying the voltage Vcc1 or Vcc2 supplied to the node N to a PA in another FEM. The third terminal 740 can provide the first voltage Vcc1 to a PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461) in the other FEM (e.g., the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460) while the first voltage Vcc1 is provided to the PA 710 in the FEM 700 from the first power supply circuit 401 via the first electrical connection 751. While the first voltage from the first power supply circuit 401 is supplied to the PA 710, the voltage of the first terminal 720 may be different from the voltage of the third terminal 740. For example, the voltage of the first terminal 720, which is an input terminal, may be different from the voltage of the third terminal 740, which is an output terminal, due to a voltage drop caused by the switch 750. The voltage of the third terminal 740 may be lower than the voltage of the first terminal 720.

[0102] According to one embodiment, the third terminal 740 can be configured to provide the second voltage Vcc2 to the PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461) in the other FEM (e.g., the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460) while the second voltage Vcc2 is provided to the PA 710 in the FEM 700 from the second power supply circuit 402 via the second electrical connection 752. While the PA 710 is supplied with the second voltage from the second power supply circuit 402, the voltage of the second terminal 730 may be different from the voltage of the third terminal 740. For example, the voltage of the second terminal 730, which is an input terminal, may be different from the voltage of the third terminal 740, which is an output terminal, due to a voltage drop caused by a switch 750. The voltage at the third terminal 740 may be lower than the voltage at the second terminal 730 .

[0103] According to one embodiment, the third terminal 740 can provide the power from the first power supply circuit 401 to another PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461) while the power from the first power supply circuit 401 is provided to the PA 710 via a first connection formed using the switch 750. The third terminal 740 can provide the power from the second power supply circuit 402 to another PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461) while the power from the second power supply circuit 402 is provided to the PA 710 via a second connection formed using the switch 750.

[0104] According to one embodiment, a first switch 750 may be disposed within the FEM 700 and configured to provide a first electrical connection 751 between the first terminal 720 and the PA 710 or a second electrical connection 752 between the second terminal 730 and the PA 710. The first switch 750 may have a first state to form the first electrical connection 751 between the first terminal 720 and the PA 710, a second state to form the second electrical connection 752 between the second terminal 730 and the PA 710, and a third state to break both the first electrical connection 751 and the second electrical connection 752. According to one embodiment, the first switch 750 can connect the path from the fourth PA 441 to the first terminal 720 to transmit the voltage Vcc1 obtained from the first terminal 720 from the first power supply circuit 401 to a terminal of the fourth FEM (e.g., the fourth FEM 440 in FIG. 4b) while transmitting a signal using the second PA 421 operating based on the voltage Vcc2 of the second power supply circuit 402. The first switch 750 can connect the path from the fourth PA 441 to the second terminal 730 to transmit the voltage Vcc2 obtained from the second terminal 730 from the second power supply circuit 402 to a terminal of the fourth FEM 440 while transmitting a signal using the first PA 411 operating based on the voltage Vcc1 of the first power supply circuit 401.

[0105] While the first switch 750 has been described as having a first state, a second state, and a third state, the first switch 750 can have a fourth state in which the first switch 750 simultaneously makes the first electrical connection 751 and the second electrical connection 752.

[0106] According to one embodiment, instead of including a power switch in each of the components to be powered by the first power circuit 401 and the second power circuit 402 (e.g., the third FEM 430, the fourth FEM 440, the fifth FEM 450 and / or the sixth FEM 460), the first switch 750 may be located in one FEM 700 (e.g., the third FEM 430). A first switch 750 arranged in one FEM 700 can electrically connect the first power supply circuit 401 to the third FEM 430, the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460, or electrically connect the second power supply circuit 402 to the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460, or electrically disconnect the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460 from the first power supply circuit 401 and the second power supply circuit 402. As described above, the first switch 750 can ensure antenna flexibility to support various frequency bands by electrically connecting the third FEM 430, the fourth FEM 440, the fifth FEM 450, and / or the sixth FEM 460 to the first power supply circuit 401 or the second power supply circuit 402.

[0107] According to one embodiment, the PA 710 may be configured to set the transmission power of the signal. The PA 710 may set the transmission power of the signal based on the first voltage Vcc1 or the second voltage Vcc2. For example, the PA 710 may receive a voltage (e.g., the first voltage Vcc1 or the second voltage Vcc2) from a power supply circuit (e.g., the first power supply circuit 401 or the second power supply circuit 402) external to the FEM 700. In response to receiving the voltage, the PA 710 may communicate the transmission power of the signal to the antenna A.

[0108] 8, the FEM 800 may further include a second switch 760 in addition to the FEM 700 of FIG. The second switch 760 may be disposed within the FEM 800 and configured to provide a third electrical connection 753 between the first switch 750 and the third terminal 740 and a fourth electrical connection 754 between the first switch 750 and the PA 710. The second switch 760 may have a first state that forms the third electrical connection 753 between the third terminal 740 and the first switch 750, a second state that forms the fourth electrical connection 754 between the first switch 750 and the PA, and a third state that disconnects both the third electrical connection 753 and the fourth electrical connection 754. According to one embodiment, the second switch 760 may include an input terminal connected to the signal path extending from the first switch 750, a first output terminal connected to the third FEM 430, and a second output terminal connected to the fourth FEM 440. The second switch 760 may be configured to selectively set in a first routing state in which a signal received at the input terminal is routed to the first output terminal or a second routing state in which a signal received at the input terminal is routed to the second output terminal. The processor 400 may be configured to control the routing state of the second switch 760 to route a voltage communicated via the input terminal to one of the third FEM 430 and the fourth FEM 440.

[0109] According to one embodiment, when the second switch 760 is set to supply voltage to a PA (e.g., the fourth PA 441, the fifth PA 451, or the sixth PA 461 in FIG. 4b) included in another FEM (e.g., the fourth FEM 440, the fifth FEM 450, or the sixth FEM 460) outside the FEM 700, the second switch 760 is set to not supply voltage to the PA 710, thereby improving stability. The second switch 760 can be set to not supply voltage to the external PA of the FEM 700 while voltage is supplied to the internal PA 710 of the FEM 700, and may be less affected by the lines extending from the PA 710.

[0110] FIG. 9 illustrates an example of an arrangement of an antenna module electrically connected to a FEM in an electronic device according to one embodiment.

[0111] 9, the electronic device 101 may include a first side 901, a second side 902 substantially aligned with the first side 901, a third side 903 substantially perpendicular to the first side 901 and extending from one end of the first side 901 to one end of the second side 902, and a fourth side 904 substantially perpendicular to the first side 901 and extending from the other end of the first side 901 to the other end of the second side 902. The lengths of the first side 901 and the second side 902 may be shorter than the lengths of the third side 903 and the fourth side 904. Of the first side 901 and the second side 902 having a short length, the first antenna A1 and / or the second antenna A2 may be disposed on the first side 901. For example, the first antenna A1 and / or the second antenna A2 may be disposed at a position where the influence of the user's hand is small when the user holds the electronic device 101. The first antenna A1 and / or the second antenna A2 may be disposed in the first region 900A. The first region 900A may be a region located close to the user's chin (or mouth) when the user uses the electronic device 101 for calling. The third antenna A3 and / or the fourth antenna A4 may be disposed in the second region 900B. The second region 900B may be a region located close to the user's ear when the user uses the electronic device 101 for calling. The electronic device 101 may further include a housing including a side wall forming a side surface. A conductive portion in the side wall disposed in the second region 900B may be configured to operate as at least a part of the third antenna A3 and the fourth antenna A4.

[0112] According to one embodiment, one of the first antenna A1 and the second antenna A2 can operate for communication with an external electronic device, and one of the remaining antennas except the operated antenna can operate. For example, when the first antenna A1 operates, one of the second antenna A2, the third antenna A3, and the fourth antenna A4 can operate together with the first antenna A1. As another example, when the second antenna A2 operates, one of the first antenna A1, the third antenna A3, and the fourth antenna A4 can operate together with the second antenna A2.

[0113] According to an embodiment, the electronic device 101 may include multiple antennas A1, A2, A3, A4. The frequency ranges supported by each of the multiple antennas A1, A2, A3, A4 may be different from each other. For example, the first antenna A1 may be electrically connected to a first FEM (e.g., the first FEM 410 in FIG. 4a or FIG. 4b) that supports signals in a first frequency range. The second antenna A2 may be connected to a second FEM (e.g., the second FEM 420 in FIG. 4a or FIG. 4b) that supports a second frequency range. The third antenna A3 and / or the fourth antenna A4 may be selectively connected to one of the multiple FEMs (e.g., the third FEM 430 and the fourth FEM 440 in FIG. 4a or FIG. 4b). The third antenna A3 may be connected to a third FEM (e.g., the third FEM 430 in FIG. 4a or 4b) or a fourth FEM (e.g., the fourth FEM 440 in FIG. 4a or 4b). The third antenna A3 may transmit a signal in a third frequency range based on the connection with the third FEM 430, and the third antenna may transmit a signal in a fourth frequency range based on the connection with the fourth FEM 440. For example, the fourth antenna A4 may be connected to a fifth FEM (e.g., the fifth FEM 450 in FIG. 4a or 4b) or a sixth FEM (e.g., the sixth FEM 460 in FIG. 4a or 4b). The fourth antenna A4 can transmit a signal in a fifth frequency range (e.g., n77 or n79 of the NR standard) based on a connection with the fifth FEM 450, and the fourth antenna A4 can transmit a signal in a sixth frequency range (e.g., n77 or n79 of the NR standard) based on a connection with the sixth FEM 460.

[0114] According to an embodiment, a processor (e.g., processor 400 of FIG. 4a or 4b) may be configured to transmit a signal to a first external electronic device using a first antenna connected to a first PA (e.g., first PA 411 of FIG. 4a or 4b) and a signal to a second external electronic device using a third antenna A3 connected to a third PA (e.g., third PA 431 of FIG. 4a or 4b) based on identifying a state change of the electronic device 101 while the signal is transmitted to a first external electronic device using a second antenna A2 via the second PA. The state change of the electronic device 101 may refer to a state change that affects antenna radiation performance due to a user's grip. The state change of the electronic device 101 may refer to a folding or unfolding state change of the foldable electronic device when the electronic device 101 is a foldable electronic device.

[0115] For example, an example of double connection using the FEM structure of FIG. 4a or FIG. 4b and the antenna arrangement structure of FIG. 9 is as shown in the table below.

[0116] [Table 2]

[0117] 4a, 4b and 9, the electronic device 101 can provide an electrical connection between the third PA 431 of the third FEM 430, the fourth PA 441 of the fourth FEM 440, the fifth PA 451 of the fifth FEM 450, or the sixth PA 461 of the sixth FEM 460 and the first power supply circuit 401, or can provide an electrical connection between the third PA 431 of the third FEM 430, the fourth PA 441 of the fourth FEM 440, the fifth PA 451 of the fifth FEM 450, or the sixth PA 461 of the sixth FEM 460 and the second power supply circuit 402 via a switch (e.g., switch 490 of FIG. 4a or 4b, or the first switch 750 of FIG. 7). A processor (e.g., processor 400 of FIG. 4a or 4b) may be configured to provide a second voltage via a second power supply circuit 402 to a third PA 431 of a third FEM 430, a fourth PA 441 of a fourth FEM 440, a fifth PA 451 of a fifth FEM 450, or a sixth PA 461 of a sixth FEM 460 connected to a third antenna A3 or a fourth antenna A4 located in a second region 900B when supplying a first voltage via a first power supply circuit 401 to a first PA 411 connected to a first antenna A1 located in a first region 900A. When the processor 400 supplies a second voltage to the second PA 412 connected to the second antenna A2 located at the lower end via the second power supply circuit 402, the processor 400 may be configured to provide a first voltage to the third PA 431 of the third FEM 430, the fourth PA 441 of the fourth FEM 440, the fifth PA 451 of the fifth FEM 450, or the sixth PA 461 of the sixth FEM 460 connected to the third antenna A3 or the fourth antenna A4 located at the upper end via the first power supply circuit 401. According to an embodiment, the first antenna A1 and the second antenna A2 supporting LTE may be disposed at the lower end of the electronic device 101 where the first side surface 901 is located. If the LTE connection is unstable while the electronic device 101 is operating in EN-DC, it may also affect communication using NR, so the antennas A1 and A2 supporting LTE may be disposed at the lower end.In one embodiment, each of the antennas A1, A2 arranged at the lower end may be connected to a power supply circuit (e.g., the first power supply circuit 401 or the second power supply circuit 402). For example, the first power supply circuit 401 connected to the first antenna A1 may be connected to the third antenna A3 and the fourth antenna A4. The second power supply circuit 402 connected to the second antenna A2 may be connected to the third antenna A3 and the fourth antenna A4. The third antenna A3 and the fourth antenna A4 may be electrically connected to the first power supply circuit 401 or the second power supply circuit 402 according to the operation of the first antenna A1 or the second antenna A2. For example, while the first power supply circuit 401 is connected to the first antenna A1, the second power supply circuit 402 may be connected to the third antenna A3 and the fourth antenna A4 via a switch (e.g., the switch 490 in FIG. 4a or FIG. 4b). While the second power supply circuit 402 is connected to the second antenna A2, the first power supply circuit 401 can be connected via the switch 490 to the third antenna A3 and the fourth antenna A4.

[0118] According to the above-described embodiment, the electronic device 101 can increase the degree of freedom of the antenna by connecting the multiple power supply circuits 401, 402 to the FEM that needs to be connected via the switch 490 arranged outside the FEM or the first switch 750 arranged inside one of the multiple FEMs. The electronic device 101 does not include a switch in each of the multiple FEMs, and by arranging a switch in one FEM or arranging a switch outside the FEM, the size of the FEM can be reduced, and the cost can be reduced by reducing the number of switches.

[0119] FIG. 10 is a simplified block diagram of an example electronic device including a PA located outside the FEM according to one embodiment.

[0122] The PAs (power amplifiers) (e.g., the first PA 411, the second PA 421, the third PA 431, the fourth PA 441, the fifth PA 451, and / or the sixth PA 461) and / or the switch 1190 may be located outside the FEM.

[0123] At least one power supply circuit (e.g., first power supply circuit 1001 or second power supply circuit 1002) can variably supply the voltage to the PA based on the control of the processor 1000 and / or a radio frequency integrated circuit (RFIC) (not shown). According to one embodiment, the voltage for the dynamic range of the PAs 1011, 1021, 1031, 1041, 1051, 1061 may be set by the processor 1000. The voltage may be set by a radio frequency integrated circuit (RFIC) (not shown) connected to the processor 1000 and each FEM 1010, 1020, 1030, 1040, 1050, 1060.

[0124] According to an embodiment, at least one power supply circuit may include a first power supply circuit 1001 and / or a second power supply circuit 1002. For example, each of the PAs 1031, 1041, 1051, 1061 connected to each of some of the FEMs 1030, 1040, 1050, 1060 may be supplied with the voltage from the first power supply circuit 1001 or the second power supply circuit 1002. For example, a first PA 1011 connected to a first FEM 1010 and external to the first FEM 1010 may be supplied with a first voltage Vcc1 from the first power supply circuit 1001. For example, a second PA 421 connected to a second FEM 1020 and external to the second FEM 1020 may be supplied with a second voltage Vcc2 from the second power supply circuit 1002. For example, the first power supply circuit 1001 may be configured to supply a first voltage Vcc1 to the PAs 1011, 1031, 1041, 1051, 1961 connected to the first FEM 1010, the third FEM 1030, the fourth FEM 1040, the fifth FEM 1050, and the sixth FEM 1060, respectively. For example, the second power supply circuit 1002 may be configured to supply a second voltage Vcc2 to the PAs 1021, 1031, 1041, 1051, 1061 connected to the second FEM 1020, the third FEM 1030, the fourth FEM 1040, the fifth FEM 1050, and the sixth FEM 1060, respectively. The first PA 1011 may be supplied with the first voltage Vcc1 via the first power supply circuit 1001. The second PA 1021 may be supplied with the second voltage Vcc2 via the second power supply circuit 1002. The third PA 1031, the fourth PA 1041, the fifth PA 1051, and the sixth PA 1061 may be supplied with the first voltage Vcc1 or the second voltage Vcc2 via the first power supply circuit 1001 or the second power supply circuit 1002, respectively.

[0125] In one embodiment, the processor 1000 can be configured to operate one PA (e.g., the third PA 1031) among the PAs 1011, 1031, 1041, 1051, 1061 supplied with a first voltage Vcc1 from the first power supply circuit 1001, and to operate the second PA 1021 supplied with a second voltage Vcc2 from the second power supply circuit 1002.

[0126] According to one embodiment, the switch 1090 can be operatively connected to the processor 1000 to supply a first voltage Vcc1 provided by the first power supply circuit 1001 and a second voltage Vcc2 provided by the second power supply circuit 1002 to a designated FEM. The processor 1000 can include a processor (processor 120 in FIG. 1), a first communication processor 212 shown in FIG. 2, a second communication processor 214, a first RFIC 222, a second RFIC 224, a third RFIC 226, a fourth RFIC 228, or a transceiver.

The first power supply circuit 1001 is always electrically connected to the first PA 1011, and can be selectively connected to the third PA 1031, the fourth PA 1041, the fifth PA 1051, and the sixth PA 1061 through a path 1091 connected to a switch 1090 and the switch 1090. The second power supply circuit 1002 is always electrically connected to the second PA 1021, and can be selectively connected to the third PA 1031, the fourth PA 1041, the fifth PA 1051, and the sixth PA 1061 through a path 1092 connected to a switch 1090 and the switch 1090. The third PA 1031 and the switch 1090 can be configured as one component. The switch 1090 may be disposed inside the substrate on which the third PA 1031 is disposed. A first terminal 1090a or a first pad of the switch 1090 may be connected to the third PA 1031. A second terminal 1090b or a second pad of the switch 1090 may be connected to a path 1091, and a third terminal 1090c or a third pad of the switch 1090 may be connected to a path 1092. However, the present invention is not limited thereto, and the switch 1090 may be formed as a component separate from the third PA 1031.

[0127] According to one embodiment, while supplying the voltage Vcc1 to the first PA 1011 via the first power supply circuit 1001, the processor 1000 can provide a voltage from the second power supply circuit 1002 to the remaining PAs 1021, 1031, 1041, 1051, 1061 except the first PA 1011 using the switch 1090. While supplying the voltage Vcc2 to the second PA 1021 via the second power supply circuit 1002, the processor 1000 can provide a voltage from the first power supply circuit 1001 to the remaining PAs 1011, 1031, 1041, 1051, 1061 except the second PA 1021 using the switch 1090.

[0128] According to one embodiment, the electronic device 101 may include PAs 1011, 1021, 1031, 1041, 1051, 1061 disposed outside the FEMs 1010, 1020, 1030, 1040, 1050, 1060. Although described as all PAs being disposed outside the FEMs 1010, 1020, 1030, 1040, 1050, 1060, this is not limiting. Some of the FEMs 1010, 1020, 1030, 1040, 1050, 1060 may include PAs within the some of the FEMs. For example, the first FEM 1010 and the second FEM 1020 may include PAs such as the first FEM 410 and the second FEM 420 of FIG. 4a or FIG. 4b. The electronic device 101 may be the same as or similar to the electronic device 101 of Figure 4b, except that the PA is located outside the FEM. The operation of the processor 1000 may be the same as or similar to the processor 400 of Figure 4a or Figure 4b.

Each FEM 1110, 1120, 1130, 1140, 1150, 1160, 1170 can be connected to one of the antennas A1, A2, A3, A4, A5, A6, A7.

[0131] According to an embodiment, the electronic device 101 may add a seventh FEM 1170 and a seventh antenna A7 to the electronic device of Fig. 4b. Descriptions of the first power supply circuit 1101, the second power supply circuit 1102, the first FEM 1110, the second FEM 1120, the third FEM 1130, the fourth FEM 1140, the fifth FEM 1150, the sixth FEM 1160, the first PA 1011, the second PA 1021, the third PA 1031, the fourth PA 1041, the fifth PA 1051, or the sixth PA 1061 that overlap with the components of Fig. 4b will be omitted.

[0132] According to an embodiment, the seventh FEM 1170 and the seventh antenna A7 can be a satellite communication FEM and a satellite communication antenna that require high power. For example, the signal transmitted through the seventh antenna A7 can be used for SOS (save our ship) service (or emergency service). Due to the wide coverage of the signal, the range of transmission power obtained using the seventh PA 1171 can be higher than the range of transmission power obtained using the other PAs (e.g., the first PA 1111, the second PA 1121, the third PA 1131, the fourth PA 1141, the fifth PA 1151, or the sixth PA 1161). Since the intensity of the current used to obtain the transmission power of the signal transmitted through the antenna A7 using the seventh PA 1171 is higher than the maximum size of the current that can be obtained from one of the power circuits of the first power circuit 1101 and the second power circuit 1102, the first power circuit 1101 and the second power circuit 1102 may be connected in parallel to the third FEM 1130 connected to the seventh PA 1171 for the transmission power of the signal transmitted through the antenna A7. For example, the voltage from the first power circuit 1101 and the voltage from the second power circuit 1102 may be provided to obtain the transmission power of the signal transmitted through the antenna A7.

[0133] According to one embodiment, the electronic device can transmit a signal using only the seventh PA 1171. In another example, the seventh PA 1171 can transmit a signal based on a first PA voltage provided by a first power supply circuit 1101 and a second voltage provided by a second power supply circuit 1102 while transmitting a signal via the first PA 1111 or the second PA 1121.

[0134] The seventh PA 1171 in the seventh FEM 1170 may require higher power than the first PA 1111, the second PA 1121, the third PA 1131, the fourth PA 1141, the fifth PA 1151, and the sixth PA 1161. To supply the required power to the seventh PA 1171, the switch 1190 may be controlled to supply the power supplied from the first power supply circuit 1101 and the power supplied from the second power supply circuit 1102 to the seventh PA 1171. To supply the required power to the seventh PA 1171, the switch 1190 may be connected to the second power supply circuit 1102 while the switch 1190 is connected to the first power supply circuit 1101. The switch 1190 can connect a path 1191 extending from the first power supply circuit 1101 and a path 1192 extending from the second power supply circuit 1102 to paths connected to the third PA 1131, the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, and / or the seventh PA 1171.

[0135] According to one embodiment, the seventh PA 1171 in the seventh FEM 1170 may require a higher current capacity than the first PA 1111, the second PA 1121, the third PA 1131, the fourth PA 1141, the fifth PA 1151, and the sixth PA 1161. The switch 1190 may be controlled to supply one of the current supplied from the first power supply circuit 1101, the current supplied from the second power supply circuit 1102, or the sum of the current supplied from the first power supply circuit 1101 and the current supplied from the second power supply circuit 1102 to the third FEM 1130. The current supplied to the third FEM 1130 may be transferred to the seventh PA 1171 in the seventh FEM 1170.

[0136] According to an embodiment, the switch 1190 may be the same part as the third FEM 1130. The switch 1190 may be disposed outside the third FEM 1130 and configured as a separate part. The switch 1190 may control the current supplied from the first power supply circuit 1101 and the current supplied from the second power supply circuit 1102 to be supplied to the seventh PA 1171 in order to supply a current capacity required for the seventh PA 1171.

[0137] 12, FEM 1200 may be the third FEM 1130 of FIG. 11.

Switch 1250 may be configured to provide a first voltage Vcc1 and / or a second voltage Vcc2 to PA 1210.

[0138] According to one embodiment, the first voltage Vcc1 of the first power supply circuit 1101 can be provided to the first terminal 1220, and the second voltage Vcc2 of the second power supply circuit 1102 can be provided to the second terminal 1230.

The switch 1250 can provide an electrical connection 1251 connected from the first terminal 1220 to the PA 1210. For example, the switch 1250 can provide a first electrical connection 1251 connecting the first power supply circuit 1101 outside the FEM 1200 and the PA 1210 by connecting the first terminal 1250a and the second terminal 1250b. The switch 1250 can provide an electrical connection 1252 connected from the second terminal 1230 to the PA 1210. For example, the switch 1250 can provide a second electrical connection 1252 connecting a second power supply circuit 1201 outside the FEM 1200 and the PA 1210 by connecting the first terminal 1250a and the third terminal 1250c.

[0139] According to one embodiment, the third terminal 1240 can be electrically connected to the PA 1210 inside the FEM 1200 and to PAs (e.g., the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, and / or the seventh PA 1171) in (or connected to) other FEMs (e.g., the fourth FEM 1140, the fifth FEM 1150, the sixth FEM 1160, and / or the seventh FEM 1170) outside the FEM 1200. The third terminal 1240 can provide a third electrical connection 1253 connected to a node N between the switch 1250 and the PA 1210 or to the outside from the switch 1250. The third electrical connection 1253 can be a path for supplying the voltage Vcc1 and / or Vcc2 supplied to the node N to other PAs.

[0140] According to one embodiment, the third terminal 1240 can provide the first voltage Vcc1 to the PA (e.g., the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, or the seventh PA 1171) in (or connected to) the other FEM (e.g., the fourth FEM 1140, the fifth FEM 1150, the sixth FEM 1160, or the seventh FEM 1170) while the first voltage Vcc1 is provided to the PA 1210 in the FEM 1200 from the first power supply circuit 1101 via the first electrical connection 1251. The third terminal 1240 can be configured to provide the second voltage Vcc2 to the PA (e.g., the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, or the seventh PA 1171) in the other FEM (e.g., the fourth FEM 1140, the fifth FEM 1150, the sixth FEM 1160, or the seventh FEM 1170) while the second voltage Vcc2 is provided to the PA 1210 in the FEM 1200 from the second power supply circuit 1102 via the second electrical connection 1252.

[0141] According to one embodiment, the switch 1250 may be disposed within the FEM 1200 and configured to provide a first electrical connection 1251 between the first terminal 1220 and the PA 1210 or a second electrical connection 1252 between the second terminal 1230 and the PA 1210. The switch 1250 may be controlled by the processor 1100. The first switch 1250 may provide a first state to form the first electrical connection 1251 between the first terminal 1220 and the PA 1210, a second state to form the second electrical connection 1252 between the second terminal 1230 and the PA 1210, a third state to disconnect both the first electrical connection 1251 and the second electrical connection 1252, and a fourth state to form both the first electrical connection 1251 and the second electrical connection 1252. The switch 1250 has been described as being disposed within the FEM 1200, but is not limited thereto and may be disposed outside the FEM 1200.

[0142] According to an embodiment, while transmitting a signal using the second PA 1121 operating based on the voltage Vcc2 of the second power supply circuit 1102, the switch 1250 can connect a path from the fourth PA 1141 (e.g., a path from the third terminal 1240 toward the node N) to the first terminal 720 (or the first pad) in order to transmit the voltage Vcc1 obtained from the first terminal 1220 from the first power supply circuit 1101 to a terminal of the fourth FEM (e.g., the fourth FEM 1140 in FIG. 11). While transmitting a signal using the first PA 1111 operating based on the voltage Vcc1 of the first power supply circuit 1101, the switch 1250 can connect a path from the fourth PA 1141 (e.g., a path from the third terminal 1240 toward the node N) to the second terminal 1230 in order to transmit the voltage Vcc2 obtained from the second terminal 1210 to a terminal of the fourth FEM 1140.

[0143] In the fourth state forming both the first electrical connection 1251 and the second electrical connection 1252, the first switch 1250 can connect a path from the fourth PA 1141 (e.g., a path from the third terminal 1240 toward the node N) to the first terminal 1220 (or the first pad) and connect the path from the fourth PA 1141 to the second terminal 1230 in order to transmit the power or current of the first power supply circuit 1101 to a terminal of the fourth FEM (e.g., the fourth FEM 1140 in FIG. 11) via the first terminal 1220 and transmit the power or current of the second power supply circuit 1102 to a terminal of the fourth FEM 1140 via the second terminal 1210. For example, the first terminal 1250a of the switch 1250 may be connected to the second terminal 1250b and simultaneously connected to the third terminal 1250c. Within the fourth state, the switch 1250 can be controlled to transfer power from the first power supply circuit 1101 and power from the second power supply circuit 1102 to the third PA 1131 (e.g., PA 1210 in FIG. 12), the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, and / or the seventh PA 1171. For example, within the fourth state, the switch 1250 can provide both a current transferred from the first power supply circuit 1101 and a current transferred from the second power supply circuit 1102 to the third PA 1131 (e.g., PA 1210 in FIG. 12), the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, and / or the seventh PA 1171. For example, in the fourth state, the switch 1250 can transmit a current to the seventh PA 1171 that is greater than the current transmitted from the first power circuit 1101 or the current transmitted from the second power circuit 1102.

[0144] 11, the switch 1190 can support multi-on for simultaneously connecting the first terminal 1250a and the second terminal 1250b, and the first terminal 1250a and the third terminal 1250c. The processor 1100 can be configured to control the switch 1190 to supply the power of the first power supply circuit 1101 and the power of the second power supply circuit 1102 to the seventh PA 1171 to utilize the antenna A7 that requires high output. For example, the processor 1100 can use the switch 1250 to provide the power of the first power supply circuit 1101 and the power of the second power supply circuit 1102 to the seventh PA 1171 to open a satellite communication channel via the seventh antenna A7. For example, the processor 1100 can control the switch 1190 or 1250 to connect the first terminal 1250a and the second terminal 1250b, and to simultaneously connect the first terminal 1250a and the third terminal 1250c. The seventh antenna A7 is described as an antenna for satellite communication, but is not limited thereto, and may be an antenna supporting other frequency bands requiring high output. For example, the processor 1100 can be configured to receive a control message from at least one external electronic device (e.g., the first base station 310 or the second base station 330 in FIG. 3) while a signal is being transmitted to the at least one external electronic device. The processor 1100 can identify a PA for a signal to be transmitted based on the control message. The processor 1100 can be configured to control the switch 1190 based on the identified PA being the seventh PA 1171, and connect the seventh PA 1171 to the first power supply circuit 1101 and the second power supply circuit 1102.

[0145] According to one embodiment, switch 490 of FIG. 4a or FIG. 4b, first switch 750 of FIG. 7 or FIG. 8, and / or switch 1090 of FIG. 10 can also support multiple on, like switch 1190 of FIG. 11 or switch 1250 of FIG. 12.

[0146] According to the above embodiment, the electronic device 101 can support a frequency band requiring high output power by simultaneously providing the power of the first power supply circuit 1101 and the power of the second power supply circuit 1102 to the third PA 1131, the fourth PA 1141, the fifth PA 1151, the sixth PA 1161, or the seventh PA 1171 through the switch 1190 or 1250. In a shadow area where it is difficult to establish a communication channel between the base station and the electronic device 101, the electronic device 1100 can establish a communication channel with a satellite communication by simultaneously providing multiple supply voltages to the PA.
