Description

Electronic device for controlling the output power of a power amplifier based on variable DPD calibration and method of operation thereof

[0001] Embodiments of the present disclosure relate to an electronic device for controlling the output power of a power amplifier based on variable DPD calibration and a method of operating the same.

[0002] With the recent advancement of mobile communication technology leading to the widespread use of mobile devices offering various functions, efforts are being made to develop 5G communication systems to meet the increasing demand for wireless data traffic. To achieve high data transmission rates and provide faster data transmission speeds, 5G communication systems are also considering implementation in ultra-high frequency bands in addition to the high frequency bands used in 3G and LTE (long term evolution) communication systems.

[0003] For example, to mitigate path loss and increase the transmission distance of radio waves in the mmWave band, beamforming, massive MIMO, full dimensional MIMO (FD-MIMO), array antenna, analog beamforming, and large-scale antenna technologies are being discussed in 5G communication systems.

[0004] The information described above may be provided as related art for the purpose of aiding understanding of the present disclosure. None of the foregoing is to be claimed as prior art related to the present disclosure, nor is it to be used to determine prior art.

When the instructions are executed individually or collectively by the at least one processor, the electronic device may cause the target power of the RF signal amplified by the power amplifier to be determined. When the instructions are executed individually or collectively by the at least one processor, the electronic device may cause the VSWR corresponding to the signal line between the at least one RFFE and the at least one antenna to be determined based on the determination that the target power exceeds a threshold power. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may cause the RFIC to output a first RF signal corresponding to a first RF gain set for a first compression point, based on confirming that the identified standing wave ratio is less than a first threshold value. When the above instructions are executed individually or collectively by the at least one processor, the electronic device may cause the RFIC to output a second RF signal corresponding to a second RF gain set for a second compression point, based on confirming that the identified standing wave ratio exceeds the first threshold value. The second RF gain may be greater than the first RF gain.

The method may include an operation of determining a standing wave ratio (VSWR) corresponding to a signal line between at least one RFFE of the electronic device and at least one antenna of the electronic device, based on determining that the target power exceeds a threshold power. The method may include an operation of controlling an RFIC of the electronic device to output a first RF signal corresponding to a first RF gain set for a first compression point, based on determining that the determined standing wave ratio is less than a first threshold value. The method may include an operation of controlling the RFIC to output a second RF signal corresponding to a second RF gain set for a second compression point, based on determining that the determined standing wave ratio exceeds the first threshold value. The second RF gain may be greater than the first RF gain.

The at least one operation may include an operation of determining a target power of an RF signal amplified by a power amplifier of the electronic device. The at least one operation may include an operation of determining a standing wave ratio (VSWR) corresponding to a signal line between at least one RFFE of the electronic device and at least one antenna of the electronic device, based on determining that the target power exceeds a threshold power. The at least one operation may include an operation of controlling an RFIC of the electronic device to output a first RF signal corresponding to a first RF gain set for a first compression point, based on determining that the determined standing wave ratio is less than a first threshold value. The above at least one operation may include an operation of controlling the RFIC to output a second RF signal corresponding to a second RF gain set for a second compression point, based on confirming that the confirmed standing wave ratio exceeds the first threshold value. The second RF gain may be greater than the first RF gain.

According to various embodiments, the second cellular network (294) may be a 5G network as defined by 3GPP. Additionally, according to one embodiment, the first communication processor (212) or the second communication processor (214) may support the establishment of a communication channel corresponding to another designated band (e.g., about 6 GHz or less) among the bands to be used for wireless communication with the second cellular network (294), and 5G network communication through the established communication channel.

[0048] The first communication processor (212) can transmit and receive data with the second communication processor (214). For example, data classified to be transmitted through the second cellular network (294) can be changed to be transmitted through the first cellular network (292). In this case, the first communication processor (212) can receive transmitted data from the second communication processor (214). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) through the inter-processor interface (213). The above inter-processor interface (213) may be implemented, for example, as a UART (universal asynchronous receiver / transmitter) interface (e.g., HS-UART (high speed-UART) or PCIe (peripheral component interconnect bus express), but there is no limitation on the type. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information, for example, using shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output strength, and RB (resource block) allocation information, to and from the second communication processor (214).

[0049] Depending on the implementation, the first communication processor (212) may not be directly connected to the second communication processor (214). In this case, the first communication processor (212) may transmit and receive data to and from the second communication processor (214) through a processor (120) (e.g., application processor). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data to and from the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no restriction on the type of interface. Alternatively, the first communication processor (212) and the second communication processor (214) may exchange control information and packet data information with the processor (120) (e.g., application processor) using shared memory.

[0050] According to one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented within a single chip or a single package. According to various embodiments, the first communication processor (212) or the second communication processor (214) may be formed within a single chip or a single package with the processor (120), the auxiliary processor (123), or the communication module (190).

[0051] The first RFIC (222) can convert a baseband signal generated by the first communication processor (212) during transmission into a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network (292) (e.g., legacy network). During reception, the RF signal is acquired from the first network (292) (e.g., legacy network) through an antenna (e.g., first antenna module (242)) and can be preprocessed through an RFFE (e.g., first RFFE (232)). The first RFIC (222) can convert the preprocessed RF signal into a baseband signal so that it can be processed by the first communication processor (212).

[0052] The second RFIC (224) can convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal of the Sub6 band (e.g., about 6 GHz or less) used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Sub6 RF signal). When receiving, the 5G Sub6 RF signal is acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., the second antenna module (244)) and can be preprocessed through an RFFE (e.g., the second RFFE (234)). The second RFIC (224) can convert the preprocessed 5G Sub6 RF signal into a baseband signal so that it can be processed by the corresponding communication processor among the first communication processor (212) or the second communication processor (214).

[0053] The third RFIC (226) can convert a baseband signal generated by the second communication processor (214) into an RF signal of the 5G Above6 band (e.g., approximately 6 GHz to approximately 60 GHz) to be used in the second cellular network (294) (e.g., 5G network) (hereinafter, 5G Above6 RF signal). Upon reception, the 5G Above6 RF signal may be acquired from the second cellular network (294) (e.g., 5G network) through an antenna (e.g., antenna (248)) and preprocessed through the third RFFE (236). The third RFIC (226) can convert the preprocessed 5G Above6 RF signal into a baseband signal so that it can be processed by the second communication processor (214). According to one embodiment, the third RFFE (236) may be formed as part of the third RFIC (226).

[0054] According to one embodiment, the electronic device (101) may include a fourth RFIC (228) separately from or at least as part of the third RFIC (226). In this case, the fourth RFIC (228) may convert a baseband signal generated by the second communication processor (214) into an RF signal (hereinafter referred to as an IF signal) in an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third RFIC (226). The third RFIC (226) may convert the IF signal into a 5G Above6 RF signal. Upon reception, the 5G Above6 RF signal may be received from the second cellular network (294) (e.g., a 5G network) through an antenna (e.g., antenna (248)) and converted into an IF signal by the third RFIC (226). The fourth RFIC (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.

[0055] According to one 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 various embodiments, if the first RFIC (222) and the second RFIC (224) in FIG. 2a or FIG. 2b are implemented as a single chip or a single package, they may be implemented as an integrated RFIC. In this case, the integrated RFIC may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to either the first RFFE (232) or the second RFFE (234). According to one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least part of a single chip or a single package. According to the example, 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 a plurality of corresponding bands.

[0056] According to one embodiment, the third RFIC (226) and the antenna (248) may be placed on the same substrate to form a third antenna module (246). For example, a wireless communication module (192) or a processor (120) may be placed on the first substrate (e.g., main PCB). In this case, the third RFIC (226) may be placed on a portion of a second substrate (e.g., sub PCB) separate from the first substrate (e.g., bottom surface), and the antenna (248) may be placed on another portion of a second substrate (e.g., top surface) to form the third antenna module (246). By placing the third RFIC (226) and the antenna (248) on the same substrate, it is possible to reduce the length of the transmission line between them. This can, for example, reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., about 6 GHz to about 60 GHz) used for 5G network communication by the transmission line. As a result, the electronic device (101) can improve the quality or speed of communication with the second network (294) (e.g., 5G network).

[0057] According to one embodiment, the antenna (248) may be formed as an antenna array comprising a plurality of antenna elements that can be used for beamforming. In this case, the third RFIC (226) may include a plurality of phase shifters (238) corresponding to the plurality of antenna elements, for example, as part of the third RFFE (236). During transmission, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal to be transmitted to the outside of the electronic device (101) (e.g., a base station of a 5G network) through the corresponding antenna element. During reception, each of the plurality of phase shifters (238) can change the phase of a 5G Above6 RF signal received from the outside through the corresponding antenna element to the same or substantially the same phase. This enables transmission or reception through beamforming between the electronic device (101) and the outside.

[0058] The second cellular network (294) (e.g., 5G network) may be operated independently of the first cellular network (292) (e.g., legacy network) (e.g., Stand-Alone (SA)) or connected (e.g., Non-Stand Alone (NSA)). For example, the 5G network may only have an access network (e.g., 5G radio access network (RAN) or next generation RAN (NG RAN)) and no core network (e.g., next generation core (NGC)). In this case, the electronic device (101) can access the access network of the 5G network and then access an external network (e.g., the Internet) under the control of the core network of the legacy network (e.g., evolved packed core (EPC)). Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., New Radio (NR) protocol information) is stored in memory (230) and can be accessed by other parts (e.g., processor (120), first communication processor (212), or second communication processor (214)).

[0059] FIG. 3 is a block diagram of an electronic device according to one embodiment of the present disclosure.

[0060] According to one embodiment, FIG. 3 illustrates an embodiment of an electronic device (101) comprising two antennas (341, 342). FIG. 3 illustrates an electronic device comprising two antennas as an example, but according to one embodiment, the electronic device (101) may comprise three or more antennas. For example, when the electronic device (101) operates in MIMO, it may receive a signal transmitted from a base station based on the MIMO through the plurality of antennas (e.g., two or more antennas).

[0061] Referring to FIG. 3, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may include a processor (120), a communication processor (260), an RFIC (310), a first RFFE (331), a second RFEE (332), a first antenna (341), a second antenna (342), a first antenna tuning circuit (341a), and / or a second antenna tuning circuit (342a). In one embodiment, the first RFFE (331) may be placed in one area within the housing of the electronic device (101), and the second RFFE (332) may be placed in another area within the housing of the electronic device (101) spaced apart from the one area, but the embodiment is not limited to the placement locations.

[0062] According to one embodiment, the RFIC (310) can convert a baseband signal generated by the communication processor (260) into a radio frequency (RF) signal used in a communication network during transmission. For example, the RFIC (310) can transmit an RF signal used in a first communication network (e.g., 5G network) or a second communication network (e.g., LTE network) to a first antenna (341) through a first RFFE (331) and a first antenna tuning circuit (341a). The RFIC (310) can also transmit an RF signal used in a first communication network (e.g., 5G network) or a second communication network (e.g., LTE network) to a second antenna (342) through a second RFFE (332) and a second antenna tuning circuit (342a).

[0063] According to one embodiment, a first antenna tuning circuit (341a) may be electrically connected to the first antenna (341), and a second antenna tuning circuit (342a) may be electrically connected to the second antenna (342). In one embodiment, the communication processor (260) may adjust (e.g., tuning) the characteristics of a signal transmitted (e.g., a transmission signal (Tx)) and a signal received (e.g., a reception signal (Rx)) through each connected antenna by adjusting the setting value of the first antenna tuning circuit (341a) and the setting value of the second antenna tuning circuit (341a).

[0064] According to one embodiment, the first antenna (341) may be set as a first receiving antenna (Rx antenna), and the second antenna (342) may be set as a second receiving antenna (Rx antenna). The electronic device (101) may receive and decode a signal transmitted from a base station through the first antenna (341) and / or the second antenna (342). For example, a signal received through the first antenna (341) may be transmitted to a communication processor (260) as a first Rx signal through a first antenna tuning circuit (341a), a first RFFE (331), and an RFIC (310). As another example, a signal received through the second antenna (342) may be transmitted to a communication processor (260) as a second Rx signal through a second antenna tuning circuit (342a), a second RFFE (332), and an RFIC (310).

[0065] According to one embodiment, the first RFFE (331) may include at least one duplexer or at least one diplexer to process the transmitted signal (Tx) and the received signal (Rx) together. As another example, the second RFFE (332) may include at least one duplexer or at least one diplexer to process the transmitted signal (Tx) and the received signal (Rx) together.

[0066] According to one embodiment, when the electronic device (101) operates in MIMO, the electronic device (101) may receive a rank from the base station for operating in MIMO. The electronic device (101) may receive a signal transmitted from the base station based on MIMO through the first antenna (341) and the second antenna (342). For convenience of explanation, the signal received through the first antenna (341) may be referred to as the first signal, and the signal received through the second antenna (442) may be referred to as the second signal.

[0067] An antenna tuning circuit according to one embodiment (e.g., a first antenna tuning circuit (341a), or a second antenna tuning circuit (342a)) may include at least one impedance tuning circuit (not shown) and / or at least one aperture tuning circuit (not shown). An impedance tuning circuit according to one embodiment may be configured to perform impedance matching with a network under the control of at least one processor (e.g., processor (120), communication processor (212, 214), and / or integrated communication processor (260)). An aperture tuning circuit according to one embodiment may change the structure of the antenna by switching on / off under the control of at least one processor. According to one embodiment, the impedance tuning circuit may be connected to an RFFE (e.g., a first RFFE (331) or a second RFFE (332)) and may be connected to a duplexer of the RFFE.

[0068] According to one embodiment, an electronic device (101) (e.g., a communication processor (260)) may change the setting value of an antenna tuning circuit according to the strength of a received signal (e.g., RSRP (reference signal received power), SNR (signal to noise ratio)) or whether an imbalance occurs. In one embodiment, the electronic device (101) may control the on / off state of a switch included in the antenna tuning circuit to change according to the change in the setting value of the antenna tuning circuit as described above.

[0069] FIG. 4 is a block diagram illustrating the structure of an RFFE included in an electronic device according to one embodiment of the present disclosure. The embodiment of FIG. 4 is to be described with reference to FIG. 5a, FIG. 5b, and FIG. 5c. FIG. 5a is an illustrative diagram illustrating the operating characteristics of a power amplifier included in an electronic device according to one embodiment of the present disclosure. FIG. 5b is an illustrative diagram illustrating the nonlinearity of a power amplifier included in an electronic device according to one embodiment of the present disclosure. FIG. 5c is an illustrative diagram illustrating a method for setting a gain for a compression point of an electronic device according to one embodiment of the present disclosure.

[0070] Referring to FIG. 4, in one embodiment, a first RFFE (331) (e.g., first RFFE (232), second RFFE (234), third RFFE (236), and / or second RFFE (332)) may include a power amplifier (401) ("PA") and a coupler (403). An RF signal provided by an RFIC (e.g., first RFIC (222), second RFIC (224), third RFIC (226), and / or RFIC (310)) may be amplified by the PA (401). A bias voltage for driving (e.g., Vcc or Vdd) may be provided to the PA (401) by a PMIC (e.g., power management module (188), "modulator"). The signal amplified by the PA (401) may be provided to a transmitting antenna (e.g., antenna module (197), first antenna module (242), second antenna module (244), third antenna module (246), antennas (248), first antenna (341), and / or second antenna (342)). The first RFFE (331) may include additional configurations other than those shown in FIG. 4. For example, the first RFFE (331) may further include a low-noise amplifier ("LNA") for amplifying an RF signal received by a receiving antenna (e.g., antenna module (197), first antenna module (242), second antenna module (244), third antenna module (246), antennas (248), first antenna (341), and / or second antenna (342)).

[0071] Referring to FIG. 5, the output power (Pout) curve (510) for the input power (Pin) of PA (401) and the power added efficiency (PAE) curve (520) of PA (401) are shown. Referring to the PAE curve (520), PA (401) can be driven at an operating point corresponding to maximum efficiency (Emax) to improve efficiency. For example, an input power Pin (Emax) corresponding to maximum efficiency (Emax) can be provided to PA (401). In one embodiment, referring to the output power (Pout) curve (510) for the input power (Pin) of PA (401), the gain of PA (401) can be measured as constant in the linear region (511). In the non-linear region (513), the gain of PA (401) can be reduced compared to the linear region (511).

[0072] Referring to FIG. 5b, in one embodiment, the PA (401) may have gain compression characteristics. Referring to reference numeral 530, an output power (Pout) curve (510) including compression points (533, 535) of the PA (401) and a linear response graph (531) of the PA (401) are shown. The linear response graph (531) of the PA (401) may represent the response of the ideal PA (401) to the gain k. Referring to the output power (Pout) curve (510) of the PA (401), at the compression point P1dB (533), the difference between the linear output power (Plinear_P1dB) of the PA (401) and the effective output power (Pout_P1dB) of the PA (401) with respect to the input power (Pin_P1dB) may be 1 dB. At the compression point P3dB (535), the difference between the linear output power (Plinear_P3dB) of PA (401) and the effective output power (Pout_P3dB) of PA (401) with respect to the input power (Pin_P3dB) may be 3 dB. At the compression point PXdB, which is not shown in FIG. 5b, the difference between the linear output power (Plinear_PXdB) of PA (401) and the effective output power (Pout_PXdB) of PA (401) with respect to the input power (Pin_PXdB) may be X dB.

[0073] Referring to reference numeral 540, the gain of PA (401) in the linear region (541) may be a value of k. In the non-linear region (543), the gain of PA (401) may be a value smaller than k. When an input power Pin (Emax) corresponding to maximum efficiency (Emax) is provided to PA (401), PA (401) may operate in the non-linear region (513). In one embodiment, the electronic device (101) (e.g., a communication processor (260) and / or an RFIC (310)) may perform a digital pre-distortion (DPD) operation so that the linearity of PA (401) is maintained even when a relatively high input power is provided. For example, the RFIC (310) may increase the input power of PA (401) based on increasing the RF gain index (RGI) value. Based on DPD operation, the linearity of PA (401) (or the gain of the linear region (511)) can be maintained even when high input power is provided. Due to DPD operation, high linearity of PA (401) can be ensured even when the voltage supplied to PA (401) (or the current consumed by PA (401)) is the same.

[0074] Referring to FIG. 5c, in one embodiment, compression points (551, 553, 555, 557) of PA (401) for various bias voltages (e.g., 2.5 V, 3 V, 3.5 V, or 4 V) supplied to PA (401) are shown. The PXdB corresponding to the compression points (551, 553, 555, 557) may be the same. In FIG. 5c, an M-line (550) connecting the compression points of PXdB described with reference to FIG. 5b is shown. The electronic device (101) (e.g., communication processor (260) or memory (130)) may store a look-up table ("LUT") including an input power (or, input power) and a bias voltage (or, supply voltage) corresponding to an output power (or, output voltage). The LUT can be hardcoded into the electronic device (101) through DPD calibration during the design (or mass production) process of the electronic device (101). For example, the electronic device (101) can obtain data satisfying a target compression point at a specific bias (e.g., 1800, 2300, 2800, and 3300) as shown in Table 1, based on power sweeping of the PA (401) operating in EPT (enhanced average power tracking) mode.

[0075]

[0076] Referring to Table 1, when the target compression is 3.5 (P3.5dB), a combination of bias voltage, RGI value, and target output power is obtained. For example, in DPD mode, when the target output power is 18.8 dBm, a bias voltage of 1800 is provided to PA (401), and an RF signal corresponding to RGI 46 can be provided to PA (401). The electronic device (101) can store a DPD table such as Table 2 based on an M-line (550) connecting data that satisfies the target compression obtained in Table 1 (e.g., data including a combination of Pout, Pin, and Vcc).

[0077]

[0078] In the lookup table of Table 2, combinations of input power (RGI) and output power (power) corresponding to the DPD index are described. The DPD index can be used to compensate for changes in the operating characteristics of the PA (401) due to temperature and / or frequency. Referring to Table 2, when the target power is 18 dBm, a bias voltage of 1814 is provided to the PA (401), and an RF signal corresponding to RGI 45 can be provided to the PA (401). When the target power is 20 dBm, a bias voltage of 2199 is provided to the PA (401), and an RF signal corresponding to RGI 47 can be provided to the PA (401). When the target power is 22 dBm, a bias voltage of 2684 is provided to the PA (401), and an RF signal corresponding to RGI 49 can be provided to the PA (401). When the target power is 26.5 dBm, a bias voltage of 4199 is provided to the PA (401), and an RF signal corresponding to RGI 54 can be provided to the PA (401). When the operating characteristics change due to temperature and frequency changes of the PA (401), the input power of the PA (401) can be aligned based on the lookup table of Table 2 to improve the ACLR (adjacent channel leakage ratio) and EVM (error vector magnitude) of the transmitted signal (Tx signal). When input power (Pin) alignment is performed, back-off of the IQ gain can be performed to ensure linearity. When back-off of the IQ gain is performed, the maximum output power (Tx power) required for the electronic device (101) may not be achieved.

[0079] FIG. 6 is a flowchart illustrating a method for providing input power to a power amplifier of an electronic device according to one embodiment of the present disclosure. The embodiment of FIG. 6 is to be described with reference to FIG. 7, FIG. 8, and FIG. 9. FIG. 7 is an illustrative diagram illustrating an impedance matching operation of an antenna tuning circuit included in an electronic device according to one embodiment of the present disclosure. FIG. 8 is an illustrative diagram illustrating a method for setting gain for a plurality of compression points of an electronic device according to one embodiment of the present disclosure. FIG. 9 is an illustrative diagram illustrating a method for setting an LUT based on the VSWR of an electronic device according to one embodiment of the present disclosure.

[0080] In one embodiment, the operations illustrated in FIG. 6 may be performed in various orders, not limited to the order illustrated. For example, the order of each operation may be changed, and at least two operations may be performed in parallel. According to one embodiment, more operations may be performed than those illustrated in FIG. 6, or at least one fewer operation may be performed.

[0081] Referring to FIG. 6, in operation 601, in one embodiment, an electronic device (101) (e.g., a communication processor (260)) can determine the target power of an RF signal amplified by a power amplifier (e.g., a PA (401)). The electronic device (101) can determine the target power required for the electronic device (101) for transmitting a transmission signal (Tx signal). The electronic device (101) can determine the target power based, for example, on configuration information received from a network, but is not limited thereto.

[0082] In operation 603, in one embodiment, the electronic device (101) can determine whether the target power exceeds a threshold power. The electronic device (101) can determine the operating mode of the PA based on whether the target power exceeds a threshold power (e.g., 16 dBm). The electronic device (101) can determine the degree of signal loss occurring in the signal line connecting the PA to the antenna when a high-power RF signal is output by the PA.

[0083] In one embodiment, based on confirming that the target power exceeds the threshold power (Operation 603-e.), the electronic device (101) can determine the voltage standing wave ratio (VSWR) in Operation 605. The electronic device (101) can determine the VSWR corresponding to a signal line between an RFFE (e.g., the first RFFE (331)) including a PA and an antenna (e.g., the first antenna (341)). In one embodiment, the electronic device (101) (e.g., a communication processor (260) and / or an RFIC (310)) can determine the VSWR through a feedback signal provided through a coupler (e.g., a coupler (403)).

[0084] In one embodiment, an antenna tuning circuit (e.g., a first antenna tuning circuit (341a)) can track an impedance matching point through an antenna impedance tuner (AIT). Referring to FIG. 7, in a user case that deviates from the center point on the Smith chart (700) (e.g., 50 ohm matching), the antenna tuning circuit can reduce signal loss by changing antenna characteristics based on an AIT code. For example, the antenna tuning circuit can reduce signal loss by tracking an impedance mismatch within a static deviation region (710) or a dynamic deviation region (720) at a set period (e.g., 50 ms).

[0085] In one embodiment, the electronic device (101) can increase the input power provided to the PA based on a plurality of DPD tables (e.g., look-up tables) when the VSWR value increases even with impedance matching by the antenna tuning circuit. In a comparative example, when the matching of the feedback signal (FBRX) is not achieved due to antenna mismatching, limited input power compensation as shown in Table 3 can be performed.

[0086]

[0087] Referring to Table 3, for the B71 band, when the standing wave ratio is 3:1 or higher, the hardware gain can correspond to 6980 or 6682. In the comparative example, when limited input power compensation is performed in EPT mode in a hand phantom scenario (e.g., a user case where impedance matching is out of match), a decrease in TRP (total radiated power) may occur compared to APT (average power tracking) mode as shown in Table 4.

[0088]

[0089] Referring to Table 4, when limited input power compensation is performed to achieve linearity of PA, an output power of PA lower than 1 dBm compared to APT mode can be measured. In one embodiment, the electronic device (101) can perform input power compensation based on a plurality of look-up tables set for each of a plurality of compression points to improve TRP.

[0090] In one embodiment, at a first compression point, a supply voltage (or bias voltage) corresponding to the target power of a power amplifier and a first RF gain (or RGI value) of a first RF signal may be set such that the difference between the linear output power of the power amplifier corresponding to the input power of the power amplifier and the effective output power of the power amplifier corresponds to a first value (e.g., 2 dB). At a second compression point, a supply voltage corresponding to the target power of the power amplifier and a second RF gain of the second RF signal may be set such that the difference between the linear output power of the power amplifier corresponding to the input power of the power amplifier and the effective output power of the power amplifier corresponds to a second value (e.g., 3 dB) greater than the first value.

[0091] Referring to FIG. 8, in one embodiment, an M-line (810) for a first compression point, an M-line (820) for a second compression point, an M-line (830) for a third compression point, and an M-line (840) for a fourth compression point are shown. The M-line (810) for the first compression point may be obtained, for example, based on data at compression points of 2 dB (811, 813, 815, 817). The M-line (820) for the second compression point may be obtained, for example, based on data at compression points of 3 dB (821, 823, 825, 827). The M-line (830) for the third compression point can be obtained based on data at, for example, a 4 dB compression point (831, 833, 835, 837). The M-line (840) for the fourth compression point can be obtained based on data at, for example, a 5 dB compression point (841, 843, 845, 847). Specific numerical values ​​corresponding to the compression points are not limited to the examples described above. In one embodiment, the electronic device (101) can increase the input power of the PA by changing the look-up table (851) referenced based on monitoring the VSWR, even when the bias voltage supplied to the PA is constant.

[0092] In operation 607, in one embodiment, the electronic device (101) can check whether the VSWR exceeds a first threshold value. The electronic device (101) can check, for example, whether the VSWR exceeds 2:1. The electronic device (101) can, as shown in Table 5, if the VSWR exceeds 2:1, impedance mismatch occurs (or the reflection coefficient increases) in the operation of the antenna tuning circuit.

[0093]

[0094] In one embodiment, the input power of the power amplifier for the target power at the second compression point (e.g., P3dB) may be greater than the input power of the power amplifier for the target power at the first compression point (e.g., P2dB). The electronic device (101) may increase the input power compensation of the PA based on DPD calibration data set for a high compression point (e.g., second compression point, third compression point, or fourth compression point). Referring to FIG. 9, in one embodiment, depending on the level of mismatch, the electronic device (101) may compensate the input power of the PA based on DPD calibration data set for different compression points. For example, in a mismatch region (910) below a first threshold, the electronic device (101) may compensate the input power of the PA by referring to a default table (e.g., PXdB). In the mismatch region (920) above the first threshold and below the second threshold, the electronic device (101) can compensate the input power of the PA by referring to a higher table (e.g., P(X+1)dB). In the mismatch region (930) above the second threshold and below the third threshold, the electronic device (101) can compensate the input power of the PA by referring to a higher table (e.g., P(X+2)dB). In one embodiment, based on confirming that the identified standing wave ratio exceeds the first threshold (Operation 607-Example), the electronic device (101) can control the RFIC (310) to output a second RF signal corresponding to a second RF gain set for the second compression point in Operation 609. Again, referring to FIG. 8, the electronic device (101) can control an RFIC (e.g., RFIC (310)) to output an RF signal of a high RGI value based on data (or a lookup table) set for a high compression point. For example, the electronic device (101) may store multiple lookup tables as described in Table 2.Each look-up table may store a bias voltage and an RGI value corresponding to the target output power based on the DPD calibration result values ​​performed for different compression points. The electronic device (101) may provide input power to the PA based on an RGI value set for a higher compression point to compensate for the input power of the PA when VSWR exceeds a threshold value. For example, a communication processor may provide a baseband signal based on DPD to the RFIC to increase the RF gain of the RF signal provided to the power amplifier by the RFIC based on confirming that the target power exceeds a threshold power.

[0095] In one embodiment, based on confirming that the confirmed standing wave ratio is less than a first threshold (operation 607-No), the electronic device (101) may, in operation 611, control the RFIC to output a first RF signal corresponding to a first RF gain set for a first compression point smaller than a second compression point. The first RF gain may be smaller than the second RF gain. The electronic device (101) may perform input power compensation of the PA based on a look-up table (or default table) set for a 2 dB compression point, for example, based on the fact that no event of impedance mismatch occurs.

[0096] FIG. 10 is a flowchart illustrating a method for providing input power to a power amplifier based on VSWR monitoring of an electronic device according to one embodiment of the present disclosure.
