According to one embodiment, the first communication processor (212) or the second communication processor (214) may establish 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 support 5G communication through the established communication channel.
[0063] The first communication processor (212) can transmit and receive data and / or signals with the second communication processor (214). For example, data classified to be transmitted via the second cellular network (294) may be changed to be transmitted via the first cellular network (292). In this case, the first communication processor (212) can receive the transmission data from the second communication processor (214) and transmit the transmission data to the first cellular network (292). For example, the first communication processor (212) can transmit and receive data with the second communication processor (214) via the processor interface (213). The above inter-processor interface (213) may be implemented as, for example, a universal asynchronous receiver / transmitter (UART) (e.g., a high speed-UART (HS-UART) or a peripheral component interconnect bus express (PCIe) interface), but there is no limitation on its type. In one embodiment, the first communication processor (212) and the second communication processor (214) may exchange data and / or control signals using, for example, a shared memory. The first communication processor (212) may transmit and receive various information, such as sensing information, information on output strength, and resource block (RB) allocation information, with the second communication processor (214).
[0064] 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 with the second communication processor (214) through the processor (120). For example, the first communication processor (212) and the second communication processor (214) may transmit and receive data with the processor (120) (e.g., application processor) through an HS-UART interface or a PCIe interface, but there is no limitation on the type of interface. In one embodiment, the first communication processor (212) and the second communication processor (214) may exchange data and / or control signals with the processor (120) (e.g., application processor) using shared memory (e.g., memory (130)).
[0065] In one embodiment, the first communication processor (212) and the second communication processor (214) may be implemented within a single chip or a single package. In one embodiment, 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).
[0066] Referring to FIG. 2B, an integrated communication processor (260) (e.g., including processing circuitry) may be used instead of the first communication processor (212) and the second communication processor (214). The integrated communication processor (260) may include various processing circuitry and / or multiple processors. For example, the term "processor" as used in this disclosure, including the claims, may include various processing circuitry including one or more processors, wherein one or more of the one or more processors may be individually and / or collectively configured to perform various functions described in this disclosure in a distributed manner. When the terms "processor," "at least one processor," and "one or more processors" as used in this disclosure are described as being configured to perform multiple functions, these terms encompass, for example, without limitation, situations where one processor performs some of the recited functions and other processor(s) perform other recited functions, as well as situations where a single processor may perform all of the recited functions. Furthermore, the one or more processors may include a combination of processors that perform various recited / disclosed functions (e.g., in a distributed manner). One or more processors may execute program instructions to achieve or perform various functions, may support both functions for communicating with a first cellular network (292) and a second cellular network (294), may be coupled to the processor (120), and may be coupled to at least one of a first transceiver (222), a second transceiver (224), or a fourth transceiver (228).
[0067] In one embodiment, when at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260) is implemented as a single chip or a single package, the single chip or single package may include a memory (e.g., memory (130)) (or storage means) that stores instructions that cause the performance of at least some of the operations performed according to embodiments of the present disclosure, and a processing circuit (or, without limitation in its name, an arithmetic circuit) for executing the instructions.
[0068] The first transceiver (222) may, upon transmission, convert a baseband signal generated by the first communication processor (212) into a radio frequency (RF) signal of a designated frequency band (e.g., about 700 MHz to about 3 GHz) used in the first cellular network (292) (e.g., a legacy network). Upon reception, the RF signal may be received from the first cellular network (292) (e.g., a legacy network) via an antenna (e.g., the first antenna (242)) and preprocessed via an RFFE (e.g., the first RFFE (232)). The first transceiver (222) may convert the preprocessed RF signal into a baseband signal so that the first communication processor (212) may process the preprocessed RF signal.
[0069] The second transceiver (224) may, upon transmission, convert a baseband signal generated by the first communication processor (212) or the second communication processor (214) into an RF signal (hereinafter, a Sub6G RF signal) of a designated frequency band (e.g., a Sub6G band of about 6 GHz or less) used in the second cellular network (294) (e.g., a 5G network). Upon reception, the Sub6G RF signal may be acquired from the second cellular network (294) (e.g., a 5G network) by an antenna (e.g., the second antenna (244)) and preprocessed through an RFFE (e.g., the second RFFE (234)). The second transceiver (224) may convert the preprocessed 5G Sub6G RF signal into a baseband signal so that it may be processed by either the first communication processor (212) or the second communication processor (214).
[0070] The third transceiver (226) can convert the baseband signal generated by the second communication processor (214) into an RF signal (hereinafter, Above6G RF signal) of a designated frequency band (e.g., 5G Above6G band of about 6 GHz to about 60 GHz) to be used in the second cellular network (294) (e.g., 5G network). Upon reception, the Above6G RF signal can be received from the second cellular network (294) (e.g., 5G network) by an antenna (e.g., antenna array (248)) and preprocessed through the third RFFE (236). The third transceiver (226) can convert the preprocessed 5G Above6G RF signal into a baseband signal so that it can be processed by the second communication processor (214). In one embodiment, the third RFFE (236) may be formed separately from the third transceiver (226) or may be formed as part of the third transceiver (226).
[0071] The electronic device (101) may include a fourth transceiver (228), separate from or at least as a part of the third transceiver (226). The fourth transceiver (228) may convert a baseband signal generated by the second communication processor (214) into a signal (hereinafter, referred to as an IF signal) of a designated intermediate frequency (IF) band (e.g., about 9 GHz to about 11 GHz) and then transmit the IF signal to the third transceiver (226). The third transceiver (226) may convert the IF signal into a 5G Above6G RF signal. Upon reception, the 5G Above6G RF signal may be received from the second cellular network (294) (e.g., a 5G network) by an antenna (e.g., an antenna array (248)) and converted into an IF signal by the third transceiver (226). The fourth transceiver (228) can convert the IF signal into a baseband signal so that the second communication processor (214) can process it.
[0072] In one embodiment, the first transceiver (222) and the second transceiver (224) may be implemented as a single chip or at least a portion of a single package. In one embodiment, when the first transceiver (222) and the second transceiver (224) in FIG. 2A or 2B are implemented as a single chip or a single package, they may be implemented as an integrated transceiver (not shown). The integrated transceiver may be connected to the first RFFE (232) and the second RFFE (234) to convert a baseband signal into a signal in a frequency band supported by the first RFFE (232) and / or the second RFFE (234), and transmit the converted signal to at least one of the first RFFE (232) and the second RFFE (234). In one embodiment, the first RFFE (232) and the second RFFE (234) may be implemented as at least a portion of a single chip or a single package. According to one example, at least one of the first antenna (242) or the second antenna (244) can be omitted or combined with another antenna module to process RF signals of corresponding multiple frequency bands.
[0073] According to one embodiment, the third transceiver (226) and the antenna array (248) may be disposed on the same substrate to form an Above6G module (246). In one embodiment, the wireless communication module (192) or the processor (120) may be disposed on a first substrate (e.g., a main printed circuit board (PCB)). The third transceiver (226) may be disposed on a portion (e.g., a lower surface) of a second substrate (e.g., a sub PCB) that is distinct from the first substrate, and the antenna array (248) may be disposed on another portion (e.g., an upper surface) to form the Above6G module (246). By disposing the third transceiver (226) and the antenna array (248) on the same substrate (e.g., a sub PCB), it is possible to reduce the length of the transmission line between the third transceiver (226) and the antenna array (248). This can reduce the loss (e.g., attenuation) of signals in the high-frequency band (e.g., approximately 6 GHz to approximately 60 GHz) used in 5G communication technology due to transmission lines. As a result, the electronic device (101) can improve the quality or speed of communication with a second cellular network (294) (e.g., a 5G network).
[0074] According to one example, the antenna array (248) may include a plurality of antenna elements that may be used for beamforming. The Above6G module (246) may include, for example, a beamforming module (BF) (238) including a plurality of phase shifters (not shown) coupled to the plurality of antenna elements as part of the third RFFE (236). Upon transmission, each of the plurality of phase shifters may shift the phase of a 5G Above6G RF signal to be transmitted to an external device (e.g., a base station of the second cellular network (294)) of the electronic device (101) via a corresponding antenna element. Upon reception, each of the plurality of phase shifters may shift the phase of a 5G Above6G RF signal received from an external device (e.g., a base station of the second cellular network (294)) via a corresponding antenna element. The beamforming module (238) enables transmission or reception through beamforming between the electronic device (101) and the external device through the above-described phase conversion.
[0075] The second cellular network (294) (e.g., a 5G network) may operate independently (e.g., Stand-Alone (SA)) or connected (e.g., Non-Stand Alone (NSA)) to the first cellular network (292) (e.g., a legacy network). For example, the 5G network may include only an access network (e.g., a 5G radio access network (RAN) or a next generation RAN (NG RAN)) and may not include a core network (e.g., a next generation core (NGC)). After accessing the access network of the 5G network, the electronic device (101) may access an external network (e.g., the Internet) under the control of the core network (e.g., an evolved packet core (EPC)) of the legacy network. Protocol information for communication with a legacy network (e.g., LTE protocol information) or protocol information for communication with a 5G network (e.g., NR protocol information) may be stored in the memory (130) and accessed by other components (e.g., the processor (120), the first communication processor (212), or the second communication processor (214)).
[0076] FIGS. 3A and 3B are diagrams illustrating exemplary connections to a network according to various embodiments.
[0077] Referring to FIG. 3A, in a standalone (SA) architecture, a user equipment (UE) (302) (e.g., an electronic device (101)) can access a 5G network (e.g., a 5G core network (5GC) (308)) via a base station (e.g., a gNB (NG node B) (304)) using a wireless communication technology (e.g., a 5G communication technology). The gNB (NG node B) (304) can form NG coverage (306) using the 5G communication technology. The user equipment (302) can transmit and receive RF signals including data and / or control signals to and from the gNB (304).
[0078] Referring to FIG. 3b, in the EN-DC architecture, a user equipment (UE) (312) (e.g., an electronic device (101)) may access an LTE network (e.g., an LTE core network (EPC) (322)) via an LTE base station (e.g., an eNB (LTE node B) (314)) using a wireless communication technology (e.g., an LTE communication technology), while simultaneously accessing the EPC (322) via a base station (e.g., an EN-DC gNB (EN-gNB) (318)) using another wireless communication technology (e.g., a 5G communication technology). The LTE coverage (316) formed by the eNB (314) may at least partially overlap with the NG coverage (320) formed by the EN-gNB (318). A user terminal (312) located in an overlapping area can transmit and receive RF signals including data and / or control signals with an eNB (314), as well as transmit and receive RF signals including data with an EN-gNB (318).

[0080] Referring to FIG. 4, the electronic device (101) may include a communication processor (CP) (e.g., including a processing circuit) (410) (e.g., at least one of the processor (120), the first communication processor (212), the second communication processor (214), or the integrated communication processor (260)), a transceiver (420) (e.g., at least one of the first transceiver (222), the second transceiver (224), the third transceiver (226), or the fourth transceiver (228)), an RFFE (430) (e.g., at least one of the first RFFE (232), the second RFFE (234), or the third RFFE (236)), an antenna (440), and / or a power supply (450).

In one embodiment, an electronic device (101), such as a user terminal (302) or a user terminal (312), may support multiple RF bands. When the electronic device (101) is configured to support EN-DC, the power supply (450) may include one or more power supply circuits (e.g., an envelope tracking (ET) modulator) for multiple power amplifiers (435) operating simultaneously for multiple RF signals within different RF bands (e.g., a 2G frequency band, a 3G frequency band, an LTE frequency band, and / or an NR frequency band).
[0082] The power supply (450) may include at least one ET modulator (e.g., ET modulator (800)) to increase the efficiency of the power amplifiers (435). The ET modulator may be configured to provide the power amplifiers (435) with a power supply voltage of a magnitude corresponding to the transmit power required by the power amplifiers (435) at each transmission instant. In one embodiment, the ET modulator (e.g., ET modulator (800)) may operate in an ET mode or an average power tracking (APT) mode, and may variably adjust the amplitude of the power supply voltage applied to the power amplifiers (435) based on information of a transmit signal input from the transceiver (420) to the power amplifiers (435) (e.g., a transmit envelope waveform in the ET mode or an average power in the APT mode), thereby allowing the power amplifiers (435) to operate at maximum efficiency.
[0083] In one embodiment, the power output from the ET modulator in ET mode may be referred to as ET power supply voltage or ET power, and the power output from the ET modulator in APT mode may be referred to as APT power supply voltage or APT power. The ET power may have a variable size depending on the transmission envelope waveform of the RF signal to be transmitted via the RFFE (430). The APT power may have a variable size depending on the average power of the RF signal to be transmitted via the RFFE (430).
[0084] In one embodiment, the magnitude of the voltage provided by the power supply (450) can be adjusted according to the RF signal to be transmitted in a frequency band (e.g., RF band) corresponding to the communication technology used in the electronic device (101). In one embodiment, the power supply (450) can be electrically connected to a battery (e.g., battery (189)) of the electronic device (101) and can output a voltage (V) of the battery (189). batt) can perform a step-up or step-down operation. The power supply (450) can provide power generated based on the step-up or step-down operation to the power amplifiers (435). Each ET modulator in the power supply (450) can be connected to one or more PAs in the RFFE (430).

[0113] The power supply structure of FIG. 7 can be made more compact by using one power supply module (702) compared to the power supply structure of FIG. 6 that uses two power supplies (602 and 604).
[0114] FIG. 8 is a drawing for explaining an exemplary structure of an ET modulator according to various embodiments.
[0115] Referring to FIG. 8, the ET modulator (800) (e.g., power supply #1 (502), power supply #2 (504), power supply #1 (602), power supply #2 (604), and / or power supply module (702)) may include a linear regulator (802), a boost converter (804), a buck converter (806), an ET port (810), and / or an APT port (812). In one embodiment, the ET modulator (800) may include a switching converter and / or a switching regulator in place of, or in addition to, the linear regulator (802). The ET port (810) is directly connected to the output of the linear regulator (802), and the APT port (812) can be connected to the output of the linear regulator (802) via the APT switch (808). The ET modulator (800) can output power (e.g., APT_1 and / or APT_2) through the APT port (812), or output power (e.g., APT_1 and / or APT_2) or modulated power (e.g., ET_1 and / or ET_2) through the ET port (810).
[0116] In one embodiment, a boost converter (804) (e.g., a step-up converter) is configured to increase the voltage (V) of an input voltage (e.g., a battery (e.g., battery (189)) batt )) is a DC-DC (direct current to direct current) converter that increases the output voltage. The boost converter (804) increases the voltage (V) of the battery (e.g., battery (189)) charged in the inductor (804a) batt ) can perform a boost operation based on the output voltage of the boost converter (804). The output voltage increased by the boost converter (804) can be provided as a power supply voltage of the linear regulator (802). The boost converter (804) also provides an auxiliary voltage (V for the buck converter (806). AUX) may occur.
[0117] In one embodiment, a buck converter (806) (e.g., a step-down converter) supplies the auxiliary voltage (V AUX ) based on the input voltage (e.g., the voltage of the battery (e.g., battery (189)) (V batt )) is a DC-DC converter that reduces the output voltage. The buck converter (806) reduces the voltage (V) of the battery (e.g., battery (189)) batt ) can perform a decompression operation. An inductor (806a) can be connected between the output of the buck converter (806) and the output of the linear regulator (802), and the output voltage of the buck converter (806) can be charged in the inductor (806a).
[0118] In one embodiment, the APT switch (808) connected between the output of the linear regulator (802) and the APT port (812) in ET mode may be turned off. The linear regulator (802) may receive an envelope waveform of a transmission signal as an input and amplify the envelope waveform of the transmission signal based on a power supply voltage provided from a boost converter (804). The output voltage of the linear regulator (802) may be output to the ET port (810) to become an ET power supply (e.g., ET_1 or ET_2) having a variable magnitude depending on the envelope waveform of the transmission signal.
[0119] In one embodiment, in APT mode, the APT switch (808) may be turned on to connect the output of the inductor (806a) to the APT port (812), and the voltage charged in the inductor (806a) may be output as an APT power source (e.g., APT_1 or APT_2) through the APT port (812). A decoupling capacitor (808a) (e.g., a capacitor of about 4.7 μF) may be connected to the APT port (812) to remove noise.
[0120] FIGS. 9A, 9B, 9C, 9D, and 9E are drawings illustrating exemplary structures of PA modules according to various embodiments.
[0121] Referring to FIG. 9a, the LB module #1 (900) (e.g., the LB module #1 (606) or the LB module #1 (706)) includes a first PA (902) (e.g., the first LB PA (606a) or the first LB PA (706a)), a transmit switch (Tx_SW) (904), a first duplexer (906a), a second duplexer (906b), a third duplexer (906c), a second PA (908) (e.g., the second LB PA (606b) or the second LB PA (706b)), an antenna switch (Ant_SW) (910), a receive switch (Rx_SW) (914), a first LNA (916a), a second LNA (916b), a third LNA (916c), and / or It may include a switch (918) (e.g., switch (606d) or switch (706d)).
[0122] In one embodiment, in a transmit mode of a second RAT (e.g., LTE and / or NR communication technology), the LB module #1 (900) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., LB) generated using the second RAT from a transceiver (e.g., the transceiver (420)). The transmit signal can be input to the first PA (902) via a designated transmit pin (e.g., LB#1 Tx1). The switch (918) can select one of two power sources (e.g., ET_1 and ET_2) provided from a power supply (450) (e.g., power supply #1 (602), power supply #2 (604), or power supply module (702)) and supply the selected power source to the first PA (902). The first PA (902) can amplify the transmission signal based on a specified amplification gain based on power (e.g., ET_1 or ET_2) provided through the switch (918), and then transmit the amplified signal to the transmission switch (904).
[0123] The transmission switch (904) can perform a switching operation so that a signal transmitted from the first PA (902) is input to a corresponding duplexer (e.g., one of the duplexers (906a, 906b, and 906c)). In one embodiment, when the LB module #1 (900) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (904) can transmit a signal corresponding to the first band to the first duplexer (906a), a signal corresponding to the second band to the second duplexer (906b), and a signal corresponding to the third band to the third duplexer (906c). The first duplexer (906a), the second duplexer (906b), and the third duplexer (906c) may be configured to perform band pass filtering (BPF) on the received signals based on the corresponding bands (e.g., the first band, the second band, and the third band).
[0124] For example, a signal transmitted from a transmission switch (904) can be input to a first duplexer (906a), and in transmission mode, the first duplexer (906a) can filter the signal input from the transmission switch (904) and then transmit it to the antenna switch (910). For example, a signal transmitted from a transmission switch (904) can be input to a second duplexer (906b), and in transmission mode, the second duplexer (906b) can filter the signal input from the transmission switch (904) and then transmit it to the antenna switch (910). For example, a signal transmitted from a transmission switch (904) can be input to a third duplexer (906c), and in transmission mode, the third duplexer (906c) can filter the signal input from the transmission switch (904) and then transmit it to the antenna switch (910).
[0125] In one embodiment, in a transmit mode of a first RAT (e.g., a 2G communication technology), the LB module #1 (900) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., LB) generated using the first RAT from a transceiver (e.g., a transceiver (420)). The transmit signal can be input to the second PA (908) through a designated transmit pin (e.g., LB#1 Tx2). The second PA (908) can amplify the transmit signal based on a designated amplification gain based on power (e.g., APT_1) provided from a power supply (450) (e.g., power supply #1 (602) or power supply module (702)), and then transmit the amplified signal to the antenna switch (910).
[0126] In one embodiment, the antenna switch (910) may transmit any one of a signal input from the first duplexer (906a), a signal input from the second duplexer (906b), a signal input from the third duplexer (906c), or a signal input from the second PA (908) to the first antenna (ANT#1) (912) so that the signal may be wirelessly transmitted by the first antenna (ANT#1) (912). In one embodiment, a coupler (CPL) may be connected to the front end of the first antenna (ANT#1) (912).
[0127] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., LB) received through a first antenna (912) may be input to an antenna switch (910), and the antenna switch (910) may perform a switching operation so that the reception signal received through the first antenna (912) is transmitted to any one of a first duplexer (906a), a second duplexer (906b), or a third duplexer (906c).
[0128] For example, the reception signal transmitted from the antenna switch (910) can be input to the first duplexer (906a), and in the reception mode, the first duplexer (906a) can transmit the reception signal transmitted from the antenna switch (910) to the reception switch (914). For example, the reception signal transmitted from the antenna switch (910) can be input to the second duplexer (906b), and in the reception mode, the second duplexer (906b) can transmit the signal input from the antenna switch (910) to the reception switch (914).

[0129] In one embodiment, the receiving switch (914) can pass a signal input from the first duplexer (906a) to the first LNA (916a). The first LNA (916a) can perform a low-noise amplification operation on the signal input from the receiving switch (914) based on a specified amplification gain, and then pass the amplified signal to a transceiver (e.g., the transceiver (420)) via a specified receiving pin (e.g., LB#1 Rx1). In one embodiment, the receiving switch (914) can pass a signal input from the second duplexer (906b) to the second LNA (916b).

In one embodiment, the receiving switch (914) can transmit a signal input from the third duplexer (906c) to the third LNA (916c). The third LNA (916c) can perform a low-noise amplification operation on the signal input from the receiving switch (914) based on a specified amplification gain, and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., LB#1 Rx3).

[0131] In one embodiment, in a transmit mode of a second RAT (e.g., LTE and / or NR communication technology), the MHB module #1 (920) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., MB or HB) generated using the second RAT from a transceiver (e.g., the transceiver (420)). The transmit signal can be input to the first PA (922) through a designated transmit pin (e.g., MHB#1 Tx1). The first PA (922) can amplify the transmit signal based on a designated amplification gain based on power (e.g., ET_2) provided from a power supply (450) (e.g., power supply #2 (604) or power supply module (702)), and then transmit the amplified signal to the transmit switch (924).
[0132] The transmission switch (924) can perform a switching operation so that a signal transmitted from the first PA (922) is input to a corresponding duplexer (e.g., one of the duplexers (926a, 926b, and 926c)). In one embodiment, when the MHB module #1 (920) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (924) can transmit a signal corresponding to the first band to the first duplexer (926a), a signal corresponding to the second band to the second duplexer (926b), and a signal corresponding to the third band to the third duplexer (926c).

For example, the first duplexer (926a), the second duplexer (926b), and the third duplexer (926c) may be configured to perform bandpass filtering (BPF) on the received signals based on their corresponding bands (e.g., the first band, the second band, and the third band).

[0144] In one embodiment, in a transmit mode of a second RAT (e.g., LTE and / or NR communication technology), the MHB module #2 (960) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., MB or HB) generated using the second RAT from a transceiver (e.g., the transceiver (420)). The transmit signal can be input to the first PA (962) through a designated transmit pin (e.g., MHB#2 Tx1). The first PA (922) can amplify the transmit signal based on a designated amplification gain based on power (e.g., ET_1) provided from a power supply (450) (e.g., power supply #1 (602) or power supply module (702)), and then transmit the amplified signal to the transmit switch (964).
[0145] The transmission switch (964) can perform a switching operation so that a signal transmitted from the first PA (962) is input to a corresponding duplexer (e.g., one of the duplexers (966a, 966b, and 966c)). In one embodiment, when the MHB module #2 (960) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (964) can transmit a signal corresponding to the first band to the first duplexer (966a), a signal corresponding to the second band to the second duplexer (966b), and a signal corresponding to the third band to the third duplexer (966c). In the transmission mode, any one of the first duplexer (966a), the second duplexer (966b), or the third duplexer (966c) can transmit a signal input from the transmission switch (964) to the antenna switch (968). The first duplexer (966a), the second duplexer (966b), and the third duplexer (966c) may be configured to perform bandpass filtering (BPF) on the received signals based on the corresponding bands (e.g., the first band, the second band, and the third band).
[0146] In one embodiment, the antenna switch (968) can transmit any one of a signal input from the first duplexer (966a), a signal input from the second duplexer (966b), or a signal input from the third duplexer (966c) to the third antenna (ANT#3) (970) so that the signal can be wirelessly transmitted by the third antenna (ANT#3) (970). In one embodiment, if necessary, a coupler (CPL) can be connected to the front end of the third antenna (ANT#3) (970).
[0147] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., MB or HB) received through a third antenna (970) may be input to an antenna switch (968), and the antenna switch (968) may perform a switching operation such that the reception signal received through the third antenna (970) is transmitted to any one of the first duplexer (966a), the second duplexer (966b), or the third duplexer (966c). For example, in a reception mode, any one of the first duplexer (966a), the second duplexer (966b), or the third duplexer (966c) may transmit the reception signal transmitted from the antenna switch (968) to the reception switch (972).
[0148] In one embodiment, the receiving switch (972) can pass a signal input from the first duplexer (966a) to the first LNA (974a). The first LNA (974a) can perform a low-noise amplification operation on the signal input from the receiving switch (972) based on a specified amplification gain, and then pass the amplified signal to the transceiver via a specified receiving pin (e.g., MHB#2 Rx1). In one embodiment, the receiving switch (972) can pass a signal input from the second duplexer (966b) to the second LNA (974b). The second LNA (974b) can perform a low-noise amplification operation on the signal input from the receiving switch (972) based on a specified amplification gain, and then pass the amplified signal to the transceiver via a specified receiving pin (e.g., MHB#2 Rx2). In one embodiment, the receiving switch (972) can transmit a signal input from the third duplexer (966c) to the third LNA (974c). The third LNA (974c) can perform a low-noise amplification operation based on a specified amplification gain on the signal input from the receiving switch (972), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., MHB#2 Rx3).
[0149] In one embodiment, the electronic device (101) may include a more miniaturized RF circuit structure (e.g., RFFE) by using a converged PA configured to support both the frequency band of 2G communication technology and the frequency band of LTE / NR communication technology. For example, the converged PA may include a decoupling capacitor smaller than about 1 nano farad (kF) to use ET power. However, since the RF signal of the 2G communication technology has a higher power level than the RF signal of the LTE / NR communication technology, the electronic device (101) may need to use a decoupling capacitor of about 1 kF or more to remove power supply noise.
[0150] Referring to FIG. 9e, a UHB module (980) (e.g., UHB module (616), or UHB module (716)) may include a PA (982) (e.g., UHB PA (716a), or UHB PA (716a)), a transmit / receive switch (Tx-Rx SW) (984), and / or a band pass filter (BPF) (986).
[0151] In one embodiment, in the transmit mode of the second RAT, the UHB module (980) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., n77 band or n78 band) generated using the second RAT from a transceiver (e.g., transceiver (420)). The transmit signal can be input to the PA (982) through a designated transmit pin (e.g., UHB#1 Tx1). The PA (982) can amplify the transmit signal based on a designated amplification gain based on power (e.g., ET_1) provided from a power supply (450) (e.g., power supply #1 (602) or power supply module (702)), and then transmit the amplified signal to the transmit / receive switch (984).
[0152] In the transmission mode, the transmit / receive switch (984) can transmit the amplified signal output from the PA (982) to the BPF (986). The BPF (986) can perform bandpass filtering on the amplified signal. The signal output from the BPF (986) can be transmitted to the fifth antenna (ANT#5) (988) so as to be wirelessly transmitted by the fifth antenna (ANT#5) (988). In one embodiment, if necessary, a coupler (CPL) can be connected to the front end of the fifth antenna (ANT#5) (988).
[0153] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., n77 band or n78 band) received through the fifth antenna (988) may be input to the transmit / receive switch (984) through the BPF (986). In the receive mode, the transmit / receive switch (984) may perform a switching operation so that the reception signal received through the fifth antenna (988) is transmitted to the transceiver. For example, in the receive mode, the reception signal may be transmitted to the transceiver through a designated receive pin (e.g., UHB#1 Rx1).
[0154] Embodiments of the present disclosure relate to an RF circuit structure that selectively supplies APT power and ET power using a switch for power supply of an integrated PA configured to support both the frequency bands of 2G communication technology and the frequency bands of LTE / NR communication technology. The RF circuit structure described above can miniaturize the RF circuit structure of an electronic device (101) and reduce material costs.

[0185] In one embodiment, at least one UHB module (1216) may include a UHB PA (1216a) configured to amplify RF signals (e.g., a seventh transmission signal) in a designated UHB (e.g., n77 band and / or n78 band) RF band of the 5G communication technology. The UHB PA (1216a) may operate based on ET_1 from the power supply module (1202).
[0186] In one embodiment, the LB module #2 (1212) may be formed identically or at least similarly to the LB module #2 (940) of FIG. 9c. In one embodiment, the MHB module #2 (1214) may be formed identically or at least similarly to the MHB module #2 (960) of FIG. 9d. In one embodiment, the UHB module #2 (1216) may be formed identically or at least similarly to the UHB module (980) of FIG. 9e.
[0187] FIGS. 13A and 13B are drawings illustrating exemplary structures of PA modules using a switch for power supply according to various embodiments.
[0188] Referring to FIG. 13a, the LB module #1 (1300) (e.g., the LB module #1 (1106) or the LB module #1 (1206)) may include a PA (1302) (e.g., the first LB PA (1106a) or the first LB PA (1106a)), a transmit switch (Tx_SW) (1304), a first duplexer (1306a), a second duplexer (1306b), a third duplexer (1306c), an antenna switch (Ant_SW) (1310), a receive switch (Rx_SW) (1314), a first LNA (1316a), a second LNA (1316b), a third LNA (1316c), and / or a switch (1308) (e.g., the switch (1106b) or the switch (1206b)).
[0189] In one embodiment, in a transmit mode of a first RAT (e.g., a 2G communication technology) or a second RAT (e.g., an LTE and / or NR communication technology), the LB module #1 (1300) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., an LB) generated using the first RAT or the second RAT from a transceiver (e.g., a transceiver (420)). The transmit signal can be input to the PA (1302) through a designated transmit pin (e.g., LB#1 Tx1). The switch (1308) can select one of two power sources (e.g., ET_1 and APT_2) provided from the power supply module (1002) (e.g., power supply #1 (1102), power supply #2 (1104), or power supply module (1202)) and supply the power source to the PA (1302). In one embodiment, the switch (1308) may, under the control of a processor (e.g., CP (410) or processor (120)), select APT_2 in a communication mode using a first RAT and select ET_1 in a communication mode using a second RAT; however, the control operation of the switch (1308) is not limited thereto and may be performed in various ways depending on the communication mode (e.g., SA or EN-DC) and frequency band performed by the electronic device (101).
[0190] In one embodiment, the PA (1302) may be an integrated PA configured to amplify both RF signals of a designated LB of a first RAT and a designated LB of a second RAT. The PA (1302) may amplify the transmission signal based on a designated amplification gain based on power (e.g., ET_1 or APT_2) provided through the switch (1308), and then transmit the amplified signal to the transmission switch (1304).
[0191] The transmission switch (1304) can perform a switching operation so that a signal transmitted from the PA (1302) is input to a corresponding duplexer (e.g., one of the duplexers (1306a, 1306b, and 1306c)). In one embodiment, when the LB module #1 (1300) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (1304) can transmit a signal corresponding to the first band to the first duplexer (1306a), a signal corresponding to the second band to the second duplexer (1306b), and a signal corresponding to the third band to the third duplexer (1306c). The first duplexer (1306a), the second duplexer (1306b), and the third duplexer (1306c) may be configured to perform bandpass filtering (BPF) on the received signals based on the corresponding bands (e.g., the first band, the second band, and the third band).
[0192] For example, a signal transmitted from a transmission switch (1304) can be input to a first duplexer (1306a), and in transmission mode, the first duplexer (1306a) can filter the signal input from the transmission switch (1304) and then transmit it to an antenna switch (1310). For example, a signal transmitted from a transmission switch (1304) can be input to a second duplexer (1306b), and in transmission mode, the second duplexer (1306b) can filter the signal input from the transmission switch (1304) and then transmit it to an antenna switch (1310). For example, a signal transmitted from a transmission switch (1304) can be input to a third duplexer (1306c), and in transmission mode, the third duplexer (1306c) can filter the signal input from the transmission switch (1304) and then transmit it to an antenna switch (1310).
[0193] In one embodiment, the antenna switch (1310) may transmit a signal selected from among a signal input from a first duplexer (1306a), a signal input from a second duplexer (1306b), or a signal input from a third duplexer (1306c) to a first antenna (ANT#1) (1312), so that the selected signal may be wirelessly transmitted by the first antenna (ANT#1) (1312). In one embodiment, a coupler (CPL) may be connected to the front end of the first antenna (ANT#1) (1312), if necessary.
[0194] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., LB) received through a first antenna (1312) may be input to an antenna switch (1310), and the antenna switch (1310) may perform a switching operation so that the reception signal received through the first antenna (1312) is transmitted to any one of a first duplexer (1306a), a second duplexer (1306b), or a third duplexer (1306c).
[0195] For example, the reception signal transmitted from the antenna switch (1310) may be input to the first duplexer (1306a), and in the reception mode of the first RAT or the second RAT, the first duplexer (1306a) may filter the reception signal transmitted from the antenna switch (1310) and then transmit it to the reception switch (1314). For example, the reception signal transmitted from the antenna switch (1310) may be input to the second duplexer (1306b), and in the reception mode of the first RAT or the second RAT, the second duplexer (1306b) may filter the signal input from the antenna switch (1310) and then transmit it to the reception switch (1314). For example, the reception signal transmitted from the antenna switch (1310) can be input to the third duplexer (1306c), and in the reception mode, the third duplexer (1306c) can filter the signal input from the antenna switch (1310) and then transmit it to the reception switch (1314).
[0196] In one embodiment, the receiving switch (1314) can transmit a signal input from the first duplexer (1306a) to the first LNA (1316a). The first LNA (1316a) can perform a low-noise amplification operation based on a specified amplification gain on the signal input from the receiving switch (1314), and then transmit the amplified signal to a transceiver (e.g., the transceiver (420)) via a specified receiving pin (e.g., LB#1 Rx1). In one embodiment, the receiving switch (1314) can transmit a signal input from the second duplexer (1306b) to the second LNA (1316b). The second LNA (1316b) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1314), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., LB#1 Rx2). In one embodiment, the receiving switch (1314) can transmit a signal input from the third duplexer (1306c) to the third LNA (1316c). The third LNA (1316c) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1314), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., LB#1 Rx3).
[0197] Referring to FIG. 13b, the MHB module #1 (1320) (e.g., the MHB module #1 (1108), or the MHB module #1 (1208)) may include at least one PA (1322) (e.g., the first MB PA (1108a), the first HB PA (1108c), the first MB PA (1208a), or the first HB PA (1208c)), a transmit switch (Tx_SW) (1324), a first duplexer (1326a), a second duplexer (1326b), a third duplexer (1326c), an antenna switch (Ant_SW) (1330), a receive switch (Rx_SW) (1334), a first LNA (1336a), a second LNA (1336b), and / or a third LNA (1336c).
[0198] In one embodiment, in a transmit mode of a first RAT (e.g., 2G) or a second RAT (e.g., LTE and / or NR communication technology), the MHB module #1 (1320) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., MB or HB) generated using the first RAT or the second RAT from a transceiver (e.g., the transceiver (420)). The transmit signal can be input to the PA (1322) via a designated transmit pin (e.g., MHB#1 Tx1). The switch (1328) can select one of two power sources (e.g., ET_2 and APT_1) provided from the power supply module (1002) (e.g., power supply #1 (1102), power supply #2 (1104), or power supply module (1202)) and supply the selected one to the PA (1322). In one embodiment, the switch (1328) may select APT_1 in a communication mode using a first RAT and select ET_2 in a communication mode using a second RAT under the control of a processor (e.g., CP (410) or processor (120)), but the control operation of the switch (1328) is not limited thereto and may be performed in various ways depending on the communication mode (e.g., SA or EN-DC) and frequency band performed by the electronic device (101).
[0199] The PA (1322) may be an integrated PA configured to amplify both RF signals of a designated MHB of a first RAT and a designated MHB of a second RAT. The PA (1322) may amplify the transmission signal based on a designated amplification gain based on power (e.g., ET_2 or APT_1) provided through the switch (1328), and then transmit the amplified signal to the transmission switch (1324).
[0200] For example, the transmission switch (1324) can perform a switching operation so that a signal transmitted from the PA (1322) is input to a corresponding duplexer (e.g., one of the duplexers (1326a, 1326b, and 1326c)). In one embodiment, when the MHB module #1 (1320) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (1324) can transmit a signal corresponding to the first band to the first duplexer (1326a), a signal corresponding to the second band to the second duplexer (1326b), and a signal corresponding to the third band to the third duplexer (1326c). In the transmit mode, any one of the first duplexer (1326a), the second duplexer (1326b), or the third duplexer (1326c) can transmit a signal input from the transmit switch (1324) to the antenna switch (1330). The first duplexer (1326a), the second duplexer (1326b), and the third duplexer (1326c) can be configured to perform bandpass filtering (BPF) on the received signals based on the corresponding bands (e.g., the first band, the second band, and the third band).
[0201] In one embodiment, the antenna switch (1330) may transmit any one signal selected from among a signal input from the first duplexer (1326a), a signal input from the second duplexer (1326b), or a signal input from the third duplexer (1326c) to the second antenna (ANT#2) (1332), so that the selected signal may be wirelessly transmitted by the second antenna (ANT#2) (1332). In one embodiment, a coupler (CPL) may be connected to the front end of the second antenna (ANT#2) (1332), if necessary.
[0202] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., MB or HB) received through a second antenna (1332) may be input to an antenna switch (1330), and the antenna switch (1330) may perform a switching operation so that the reception signal received through the second antenna (1332) is transmitted to any one of the first duplexer (1326a), the second duplexer (1326b), or the third duplexer (1326c). For example, in a reception mode, any one of the first duplexer (1326a), the second duplexer (1326b), or the third duplexer (1326c) may filter the reception signal transmitted from the antenna switch (1330) according to the corresponding band and then transmit the filtered signal to the reception switch (1334).
[0203] In one embodiment, the receiving switch (1334) can transmit a signal input from the first duplexer (1326a) to the first LNA (1336a). The first LNA (1336a) can perform a low-noise amplification operation based on a specified amplification gain on the signal input from the receiving switch (1334), and then transmit the amplified signal to a transceiver (e.g., the transceiver (420)) through a specified receiving pin (e.g., MHB#1 Rx1). In one embodiment, the receiving switch (1334) can transmit a signal input from the second duplexer (1326b) to the second LNA (1336b). The second LNA (1336b) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1334), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., MHB#1 Rx2). In one embodiment, the receiving switch (1334) can transmit a signal input from the third duplexer (1326c) to the third LNA (1336c). The third LNA (1336c) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1334), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., MHB#1 Rx3).

[0206] In operation 1420, the processor (e.g., CP (410) or processor (120)) generates a first switching control signal to control the first switch (1014) (e.g., switch (1106b) or switch (1206b)) to provide ET_1 to the first PA (1012) (e.g., first LB PA (1106a) or first LB PA (1206a)) in a second communication mode (e.g., LTE SA, NR SA or EN-DC) using a second RAT (e.g., LTE or NR communication technology), and / or generates a second switching control signal to control the second switch (1024) (e.g., switch (1108b) or switch (1208b)) to provide ET_2 to the second PA (1022) (e.g., first MB PA (1108a) or first MB PA (1208a)). It can happen.

In one embodiment, power supply #1 (1502) and power supply #2 (1504) may be replaced with a single power supply module (e.g., power supply module (1202)).
[0212] In one embodiment, the LB module #1 (1506) may include a first LB PA (1506a) (e.g., an integrated PA or a PA for 2G / LTE / NR LB) (e.g., the first PA (1012)) configured to amplify RF signals (e.g., a first transmit signal) corresponding to the LB of the first RAT and the LB of the second RAT, and a switch (1506b) (e.g., the first switch (1014)) for selecting power provided to the first LB PA (1506a). In one embodiment, the switch (1506b) may include a single pole three through (SP3T) switch. The switch (1506b) may select any one of ET_1 from power supply #1 (1502), ET_2 from power supply #2 (1504), and APT_2 from power supply #2 (1504) and provide it to the first LB PA (1506a) under the control of a processor (e.g., CP (410) or processor (120)).

[0213] In one embodiment, the MHB module #1 (1508) may include a first MB PA (1508a) (e.g., an integrated PA or a PA for 2G / LTE / NR MB) configured to amplify RF signals (e.g., a second transmit signal) corresponding to the MB of the first RAT and the MB of the second RAT, a first HB PA (1508c) (e.g., a PA for LTE / NR HB) configured to amplify RF signals (e.g., a third transmit signal) corresponding to the HB of the second RAT, and a switch (1508b) (e.g., a second switch (1024)) for selecting power provided to the first MB PA (1508a). The switch (1508b) can select either ET_2 from power supply #2 (1504) or APT_1 from power supply #1 (1502) under the control of a processor (e.g., CP (410) or processor (120)) and provide the selected either to the first MB PA (1508a).

[0217] The power supply structure of FIG. 15, compared to the power supply structure of FIG. 11 or FIG. 12, allows the first LB PA (1506a) to selectively use either of the two ET power supplies in the communication mode of SA or EN-DC via a three-path switch (1506b). In one embodiment, the processor (e.g., CP (410) or processor (120)) controls the switch (1506b) to supply ET_2 to the first LB PA (1506a) of the LB module #1 (1506) in the communication mode of EN-DC, thereby enabling dual connection of the EN-DC via both the LB module #1 (1506) using ET_2 and the LB module #2 (1512) using ET_1.
[0218] FIG. 16 is a drawing illustrating an exemplary structure of a PA module using a three-path switch according to various embodiments.
[0219] Referring to FIG. 16, the LB module #1 (1600) (e.g., the LB module #1 (1506)) may include a PA (1602) (e.g., the first LB PA (1506a)), a transmit switch (Tx_SW) (1604), a first duplexer (1606a), a second duplexer (1606b), a third duplexer (1606c), an antenna switch (Ant_SW) (1610), a receive switch (Rx_SW) (1614), a first LNA (1616a), a second LNA (1616b), a third LNA (1616c), and / or a switch (1608) (e.g., the switch (1506b)).
[0220] In one embodiment, in a transmit mode of a first RAT (e.g., a 2G communication technology) or a second RAT (e.g., an LTE and / or NR communication technology), the LB module #1 (1600) can receive an RF signal (e.g., a transmit signal) of a designated frequency band (e.g., an LB) generated using the second RAT from a transceiver (e.g., a transceiver (420)). The transmit signal can be input to the PA (1602) via a designated transmit pin (e.g., LB#1 Tx1). The switch (1608) can select one of three power sources (e.g., ET_1, ET_2, and APT_2) provided from the power supply module (1002) (e.g., power supply #1 (1502), power supply #2 (1504), or power supply module (1202)) and supply the selected power source to the PA (1602). In one embodiment, the switch (1608) may, under the control of a processor (e.g., CP (410) or processor (120)), select APT_2 in a communication mode using a first RAT, and select ET_1 or ET_2 in a communication mode using a second RAT; however, the control operation of the switch (1608) is not limited thereto and may be performed in various ways depending on the communication mode (e.g., SA or EN-DC) and frequency band performed by the electronic device (101).
[0221] The PA (1602) may be an integrated PA configured to amplify both RF signals of a designated LB of a first RAT and a designated LB of a second RAT. The PA (1602) may amplify the transmission signal based on a designated amplification gain based on power (e.g., ET_1, ET_2, or APT_2) provided through the switch (1608), and then transmit the amplified signal to the transmission switch (1604).
[0222] The transmission switch (1604) can perform a switching operation so that a signal transmitted from the PA (1602) is input to a corresponding duplexer (e.g., one of the duplexers (1606a, 1606b, and 1606c)). In one embodiment, when the LB module #1 (1600) can support a total of three bands of a first band, a second band, and a third band, the transmission switch (1604) can transmit a signal corresponding to the first band to the first duplexer (1606a), a signal corresponding to the second band to the second duplexer (1606b), and a signal corresponding to the third band to the third duplexer (1606c). The first duplexer (1606a), the second duplexer (1606b), and the third duplexer (1606c) may be configured to perform bandpass filtering (BPF) on the received signals based on the corresponding bands (e.g., the first band, the second band, and the third band).
[0223] For example, a signal transmitted from a transmission switch (1604) can be input to a first duplexer (1606a), and in transmission mode, the first duplexer (1606a) can filter the signal input from the transmission switch (1604) and then transmit it to an antenna switch (1610). For example, a signal transmitted from a transmission switch (1604) can be input to a second duplexer (1606b), and in transmission mode, the second duplexer (1606b) can filter the signal input from the transmission switch (1604) and then transmit it to an antenna switch (1610). For example, a signal transmitted from a transmission switch (1604) can be input to a third duplexer (1606c), and in transmission mode, the third duplexer (1606c) can filter the signal input from the transmission switch (1604) and then transmit it to an antenna switch (1610).
[0224] In one embodiment, the antenna switch (1610) may transmit a signal selected from among a signal input from a first duplexer (1606a), a signal input from a second duplexer (1606b), or a signal input from a third duplexer (1606c) to a first antenna (ANT#1) (1612), so that the selected signal may be wirelessly transmitted by the first antenna (ANT#1) (1612). In one embodiment, a coupler (CPL) may be connected to the front end of the first antenna (ANT#1) (1612), if necessary.
[0225] In one embodiment, a signal (e.g., a reception signal) of a designated frequency band (e.g., LB) received through a first antenna (1612) may be input to an antenna switch (1610), and the antenna switch (1610) may perform a switching operation so that the reception signal received through the first antenna (1612) is transmitted to any one of a first duplexer (1606a), a second duplexer (1606b), or a third duplexer (1606c).
[0226] For example, the reception signal transmitted from the antenna switch (1610) may be input to the first duplexer (1606a), and in the reception mode of the first RAT or the second RAT, the first duplexer (1606a) may filter the reception signal transmitted from the antenna switch (1610) and then transmit it to the reception switch (1614). For example, the reception signal transmitted from the antenna switch (1610) may be input to the second duplexer (1606b), and in the reception mode of the first RAT or the second RAT, the second duplexer (1606b) may filter the signal input from the antenna switch (1610) and then transmit it to the reception switch (1614). For example, the reception signal transmitted from the antenna switch (1610) can be input to the third duplexer (1606c), and in the reception mode, the third duplexer (1606c) can filter the signal input from the antenna switch (1610) and then transmit it to the reception switch (1614).
[0227] In one embodiment, the receiving switch (1614) can pass a signal input from the first duplexer (1606a) to the first LNA (1616a). The first LNA (1616a) can perform a low-noise amplification operation based on a specified amplification gain on the signal input from the receiving switch (1614), and then pass the amplified signal to a transceiver (e.g., transceiver (420)) through a specified receiving pin (e.g., LB#1 Rx1). In one embodiment, the receiving switch (1614) can pass a signal input from the second duplexer (1606b) to the second LNA (1616b). The second LNA (1616b) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1614), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., LB#1 Rx2). In one embodiment, the receiving switch (1614) can transmit a signal input from the third duplexer (1606c) to the third LNA (1616c). The third LNA (1616c) can perform a low-noise amplification operation based on a specified amplification gain on a signal input from the receiving switch (1614), and then transmit the amplified signal to the transceiver through a specified receiving pin (e.g., LB#1 Rx3).
