Referring to FIG. 1 , the electronic device 101 may include a processor 120, a first RFIC 130, a second RFIC 140, an RFFE 160, and an antenna 190.

For example, the electronic device 101 may include at least a portion of the electronic device 501 in FIG. 5, which will be illustrated below. For example, processor 120 may include at least a portion of processor 520 in FIG. 5 as illustrated below. For example, RFIC 130, or RFFE 160 may include at least a portion of wireless communication module 592 in FIG. 5 and/or at least a portion of antenna module 597 in FIG. 5. For example, the antenna 190 may include at least a portion of the antenna module 597 in FIG. 5 . However, it is not limited to this.

For example, the RFFE 160 may include a coupler 170 connected to the antenna 190. For example, coupler 170 may generate a forward coupling signal that is part of a signal transmitted through antenna 190 and a reverse coupling signal that is at least part of a signal reflected according to the transmission of the signal. It can be used to obtain. For example, the electronic device 101 may include a forward path 171 for the forward coupling signal and a reverse path 172 for the reverse coupling signal. For example, each of the forward path 171 and the reverse path 172 may be connected to the coupler 170. For example, coupler 170 may include a port for the forward path 171 and a port for the reverse path 172. For example, the RFFE 160 may include a power amplifier (PA) 161 connected to the coupler 170. For example, in this document, “the first component and the second component are connected” means not only the first component and the second component are directly connected, but also the first component and the second component are connected. It can indicate that two components are connected through a third component. For example, the PA 161 may be connected to the coupler 170 through the duplexer 180. For example, the RFFE 160 may include a duplexer 180 between the PA 161 and the coupler 170. RFFE 160 may include a switch that replaces duplexer 180. The switch can be illustrated through FIG. 2.

Figure 2 shows an example of a switch included within an RFFE.

Referring to FIG. 2, the RFFE 160 may include a switch 200 instead of the duplexer 180. For example, when the RFFE 160 is an RFFE for frequency division duplex (FDD), the RFFE 160 may include a duplexer 180. For example, when the RFFE 160 is an RFFE for time division duplex (TDD), the RFFE 160 may include the switch 200. For example, the switch 200 has a first terminal 201 connected to the PA 161, a second terminal 202 connected to a low noise amplifier (LNA) 162, which will be illustrated below, and a coupler 170. ) may include a third terminal 203 connected to. For example, the switch 200 is in a first state 204 connecting the first terminal 201 and the third terminal 203 within time resources for transmitting a signal through the antenna 190. There may be. For example, the switch 200 is in the second state 205 connecting the second terminal 202 and the third terminal 203 within time resources for receiving a signal through the antenna 190. There may be.

Referring again to FIG. 1, PA 161 may be used to set the transmission power of a signal transmitted through antenna 190. For example, the duplexer 180 may be used to distinguish between a signal transmitted through the antenna 190 and a signal received through the antenna 190.

For example, the first RFIC 130 may include a transmission circuit 131 including one or more Tx (transmit) chains. For example, the transmission circuit 131 may be connected to the PA 161. For example, the one or more Tx chains may include a mixer for up-conversion. For example, the mixer may be connected to a local oscillator (LO) of the first RFIC 130. For example, each of the one or more Tx chains may include a digital to analog converter (DAC) and a PA. For example, the DAC can be used to convert a digital signal input to the DAC into an analog signal. For example, the PA can be used to amplify a signal input to the PA. However, it is not limited to this.

For example, the first RFIC 130 may include a receiving circuit 132 including a receive (Rx) chain. For example, receive circuitry 132 may be connectable with forward path 171 from coupler 170 . For example, the Rx chain may include a mixer for down conversion. For example, the mixer in the Rx chain may be connected to the LO. For example, one Tx chain in the transmit circuit 131 and the Rx chain in the receive circuit 132 may share the LO. For example, the receiving circuit 132 may be connected to the LO, which is connected to the transmitting circuit 131, unlike the other receiving circuit 142 of the second RFIC 140, which will be illustrated below. For example, the Rx chain may include an analog to digital converter (ADC) and a PA. For example, the PA can be used to amplify a signal input to the PA. For example, the ADC can be used to convert an analog signal input to the ADC into a digital signal.

For example, the first RFIC 130 may further include a receiving circuit 133. For example, receiving circuit 133 may be separate or electrically disconnected from coupler 170, unlike receiving circuit 132, which may be coupled to the forward path 171 from coupler 170. For example, the receiving circuit 133 may be electrically connected to the LNA 162 connected to the duplexer 180, unlike the receiving circuit 132 connectable to the forward path 171 from the coupler 170. For example, the receiving circuit 133 receives through the antenna 190, unlike the receiving circuit 132 that is used to obtain the forward coupled signal provided through the forward path 171 from the coupler 170. It can be used to obtain a signal that is

For example, the second RFIC 140 may include another receive circuit 142 that includes another receive (Rx) chain. For example, other receiving circuits 142 may be connectable with the reverse path 172 from coupler 170. For example, the different Rx chains may include different mixers for down-conversion. For example, the other mixers in the other Rx chains may be electrically disconnected from the LO, unlike the mixers in the Rx chains of the receive circuit 132. However, it is not limited to this. For example, the other Rx chain of the other receiving circuit 142 may include an analog to digital converter (ADC) and a PA. For example, the PA can be used to amplify a signal input to the PA. For example, the ADC can be used to convert an analog signal input to the ADC into a digital signal.

Although not shown in FIG. 1 for convenience of explanation, the second RFIC 140 may further include a receiving circuit. For example, the receiving circuit may be separate or electrically disconnected from the coupler 170, unlike other receiving circuits 142 that may be coupled to the reverse path 172 from the coupler 170. For example, the receiving circuit may be coupled to an LNA (e.g., LNA 162) coupled to the duplexer 180, unlike other receiving circuits 142 that can be coupled to the reverse path 172 from the coupler 170. there is. For example, the receiving circuit, unlike other receiving circuits 142 used to obtain the reverse coupling signal provided through the reverse path 172 from the coupler 170, receives the reverse coupling signal received through the antenna 190. It can be used to acquire a signal.

For example, the processor 120 may transmit the signal 191 obtained through the transmission circuit 131 through the antenna 190 at a power set using the PA 161. For example, the processor 120 may receive a forward coupling signal 192 of the signal 191 provided through the forward path 171 according to the transmission of the signal 191. 132). For example, since the forward coupling signal 192 is part of the signal 191, the processor 120 receives the forward coupling signal through the receiving circuit 132 connected to the LO connected to the transmitting circuit 131. You can obtain (192).

For example, the processor 120 may receive a reverse coupling signal 193 of the signal 191 provided via the reverse path 172 according to the transmission of the signal 191 to another receiving circuit 142. It can be obtained through . For example, the processor 120 may obtain the reverse coupling signal 193, which is at least a portion of the signal reflected from the antenna 190, through another receiving circuit 142 according to the transmission of the signal 191. .

For example, the electronic device 101 has a forward path 171 and a reverse path ( 172), the electronic device 101 can reduce noise that may be caused while acquiring the forward coupling signal 192 and the reverse coupling signal 193. For example, the connection between the forward path 171 and the receiving circuit 132 is maintained while obtaining the forward coupled signal 192, and the connection between the reverse path 172 and the other receiving circuit 142 is maintained. Because the connection is maintained while acquiring the reverse coupling signal 193, the electronic device 101 can reduce the noise.

For example, the processor 120 may perform various operations based on the forward coupling signal 192 and the reverse coupling signal 193. For example, the processor 120 may identify the strength of a signal to be transmitted through the antenna 190 based on the forward coupling signal 192 and the reverse coupling signal 193. For example, processor 120 may identify the power of signal 191 transmitted through antenna 190 based on forward coupling signal 192. For example, the processor 120 may identify the impedance of the antenna 190 based on the forward coupling signal 192 and the reverse coupling signal 193. For example, the processor 120 may identify the reflection coefficient of the antenna 190 based on the forward coupling signal 192 and the reverse coupling signal 193. For example, the processor 120 may adjust the impedance of the antenna 190 through the tuner 181 based on the forward coupling signal 192 and the reverse coupling signal 193. For example, the processor 120 determines that an external object (e.g., at least a part of the body) is located within a certain distance from the electronic device 101 based on the forward coupling signal 192 and the reverse coupling signal 193. You can determine whether it works or not. For example, the processor 120 may identify whether the electronic device 101 is gripped based on the forward coupling signal 192 and the reverse coupling signal 193. However, it is not limited to this.

For example, the processor 120 may perform various operations illustrated above based on compensating for the difference between the phase of the forward coupling signal 192 and the phase of the reverse coupling signal 193. can be run. For example, because the length of forward path 171 may differ from the length of reverse path 172, processor 120 may perform the various operations based on compensating for the difference.

As described above, electronic device 101 includes a forward path 171 from coupler 170, a reverse path 172 from coupler 170, receiving circuitry 132, and other receiving circuitry 142. Through this, the forward coupling signal 192 and the reverse coupling signal 193 can be obtained. For example, electronic device 101 may include a forward path 171 from coupler 170, a reverse path 172 from coupler 170, and a receiving circuit 132 connectable with forward path 171, and another receiving circuit 142 connectable with the reverse path 172, the electronic device 101 is capable of preventing noise caused while the forward coupling signal 192 and reverse coupling signal 193 are acquired. can reduce it.

For example, each of the forward path 371 and the reverse path 372 may be connected to the coupler 370.

For example, the electronic device 101 may include a first switch 350. For example, the first switch 350 electrically connects one of the forward paths 171 from the coupler 170 and the forward path 371 from the other coupler 370 to the receiving circuit 132. It can be used to connect. For example, since the PA 161 and the other PA 361 are each connected to the transmission circuit 131, the reception circuit 132 connected to the LO connected to the transmission circuit 131 is connected to the coupler 170. It may be electrically connectable to the forward path 171 from or to the forward path 371 from another coupler 370 through the first switch 350.

For example, processor 120 may identify the strength of a signal to be transmitted through antenna 390 based on forward coupling signal 302 and reverse coupling signal 303. For example, processor 120 may identify the power of signal 301 transmitted through antenna 390 based on forward coupling signal 302. For example, the processor 120 may identify the impedance of the antenna 390 based on the forward coupling signal 302 and the reverse coupling signal 303. For example, the processor 120 may identify the reflection coefficient of the antenna 390 based on the forward coupling signal 302 and the reverse coupling signal 303. For example, the processor 120 may adjust the impedance of the antenna 390 based on the forward coupling signal 302 and the reverse coupling signal 303.
