Although an RFFE module including a power amplifier for a transmission path is illustrated in FIG. 2 , embodiments of the present disclosure are not limited thereto. For example, in addition to the PAMid including the transmit path, the RFFE module may also be used as an example of an RFFE module, such as an LPAMid further including a component for the receive path (e.g., a low noise amplifier (LNA)). A module including a power amplifier that receives a supply voltage from a power supply circuit (250) (e.g., the first power supply circuit (251), the second power supply circuit (252), or the third power supply (230)) may be understood as an RFFE module of the electronic device (101) according to an embodiment of the present disclosure.

The power supply circuit (250) may provide a plurality of supply voltages for a plurality of RFFE modules. The power supply circuit (250) may supply a supply voltage to each RFFE module of the plurality of RFFE modules. For example, the power supply circuit (250) may be in the form of a plurality of modulators implemented as a single module (or IC). The power supply circuit (250) may be a power supply module including a plurality of cores. For example, the power supply module may include a first power supply circuit (251) and a second power supply circuit (252). For another example, the power supply circuit (250) may include a first power supply circuit (251) and a second power supply circuit (252) implemented as separate modules. Power being supplied to the RFFE module may indicate that a supply voltage is applied for the PA of the RFFE module.

The second power path (292) can be formed across the second output port of the module.

APT is a technology for providing a DC voltage of a magnitude according to the communication channel status to the power amplifier. For the supply voltage according to APT, the power supply circuit (250) can be configured to provide power to the power amplifier of a specified magnitude through a DC-DC converter. In addition to APT, terms such as APT mode, APT state, APT operation, APT method, variable DC voltage mode, variable DC power mode, and / or terms having equivalent technical / functional meanings can be used for APT. The power supply circuit (250) can be configured to provide a supply voltage based on APT. For example, the first power supply circuit (251) can be configured to provide a first supply voltage (271) based on APT. The first power supply circuit (251) can generate a first supply voltage (271) according to the APT from the voltage from the battery (288). For example, the second power supply circuit (252) can be configured to provide a second supply voltage (272) based on the APT. The second power supply circuit (252) can generate a second supply voltage (272) according to the APT from the voltage from the battery (288). To generate the supply voltage according to the APT, each power supply circuit can include an APT switch (not shown) and a buck converter circuit (not shown). The APT switch can be configured to electrically connect a capacitor to the buck converter circuit. The supply voltage according to the APT can be influenced by the capacitor. A DC voltage is generated through the buck converter circuit, and the capacitor can be used to maintain a constant voltage.For example, the first power supply circuit (251) may be electrically connected to the first capacitor (281) to keep the first supply voltage (271) constant according to the APT. For example, the second power supply circuit (252) may be electrically connected to the second capacitor (282) to keep the second supply voltage (272) constant according to the APT.

[0050] A buck converter circuit used to generate a supply voltage according to APT may be configured to charge and discharge a capacitor using the electromotive force of an inductor through a switching element. Noise resulting from this switching operation may be detected as an unwanted component through a PA (e.g., PA (244)). In addition, if the current consumed in the PA (244) exceeds the allowable value in the power supply circuit (250) (e.g., a current exceeding the allowable value is supplied to the regulator of the power supply circuit (250), exceeding the limit current capacity of the inductor), it may be difficult to supply a stable voltage to the PA (244), and damage may occur to the power supply circuit (250). In addition, a multilayer ceramic capacitor (MLCC) capacitor may be considered to support a large capacity within a limited mounting area. However, when the buck converter circuit of the power supply circuit is switched to provide a supply voltage according to the APT, the voltage applied across the MLCC capacitor changes, causing physical deformation of the capacitor and causing the PCB on which the MLCC capacitor is placed to vibrate. This physical deformation and vibration may cause audible noise.

[0051] To alleviate one or more of the problems described above, the present disclosure describes a circuit structure for providing a third supply voltage from a third power source (230) separately from a first power supply circuit (251) and a second power supply circuit (252). The power supply circuit (250) may include a first switching circuit (261) and a second switching circuit (262). The first switching circuit (261) may be configured to selectively connect or not connect a first power path (291) and a third power path (293). The second switching circuit (262) may be configured to selectively connect or not connect a second power path (292) and a third power path (293). If it is difficult to provide the first supply voltage (271) through the first power supply circuit (251) (or if it is not desirable for any of the above reasons), the first switching circuit (261) can electrically connect the first power path (291) and the third power path (293). Instead of the first supply voltage (271), the third supply voltage (273) can be provided to the RFFE module (240) through the first power path (291). For example, the third supply voltage (273) can be provided to the PA (244) of the RFFE module (240). If it is difficult to provide the second supply voltage (272) through the second power supply circuit (252), the second switching circuit (262) can electrically connect the second power path (292) and the third power path (293). Instead of the second supply voltage (272), a third supply voltage (273) may be provided to the RFFE module (240) via the second power path (292). For example, the third supply voltage (273) may be provided to the PA (244) of the RFFE module (240). The PA (244) of the RFFE module (240) may obtain the supply voltage via one of the first power path (291) and the second power path (292) under the control of the processor (210) or the RF transceiver (220).When the first power path (291) is connected to the PA (244), the first supply voltage (271) or the third supply voltage (273) can be provided to the PA (244). When the second power path (292) is connected to the PA (244), the second supply voltage (272) or the third supply voltage (273) can be provided to the PA (244). Even if a problem occurs in the power supply circuit that provides the supply voltage to the PA (244) of the RFFE module (240), the electronic device (101) according to embodiments of the present disclosure can operate normally by supplying a separate supply voltage (e.g., the third supply voltage (273)) to the PA (244) of the RFFE module (240) through another path. In other words, by using an alternative power source, normal operation of the electronic device (101) can be maintained under any circumstances.

[0052] Control of the first switching circuit and the second switching circuit (and the switching circuits of the RFFE modules described later in this disclosure) may be performed by a controller or processor of the electronic device. For example, if the power required for the RFFE module is detected to exceed a threshold, the first switching circuit / second switching circuit may be controlled to provide a third supply voltage to the RFFE module. Alternatively, if a characteristic of the required power that leads to undesirable oscillation of one of the capacitors 281 or 282 is detected, the first switching circuit / second switching circuit may be controlled to provide a third supply voltage to the RFFE module.

[0053] In other words, when the first switching circuit (261) is in the first state (i.e., the first switching state), it is configured to short-circuit the third supply voltage (273) from the RFFE module (240) / PA (244) (e.g., short-circuit from the first power path (291)), and when the first switching circuit (261) is in the second state (i.e., the second switching state), it is configured to connect the third supply voltage (273) to the RFFE module (240) / PA (244) (e.g., connect through the first power path (291)). When the second switching circuit (262) is in the first state (i.e., the first switching state), the third supply voltage (273) is configured to short-circuit from the RFFE module (240) / PA (244) (e.g., short-circuit from the second power path (292)), and when the second switching circuit (262) is in the second state (i.e., the second switching state), the third supply voltage (273) is configured to connect to the RFFE module (240) / PA (244) (e.g., through the second power path (292)). It is expected, but not limited, that the first power supply circuit and the second power supply circuit will not output their respective supply voltages when the first and second switching circuits are in their respective second states. For example, the first switching circuit and / or the second switching circuit may be in a second state (i.e., a state in which the third supply voltage is connected to the first / second power path / RFFE module) when the first supply voltage / second supply voltage is not provided to the RFFE during power amplifier operation. Each switching circuit contemplated in the present disclosure may have multiple different states, and the connection (i.e., electrical path) provided in each state may be different.

[0054] The present disclosure describes, but is not limited to, a method for supplying a first supply voltage, a second supply voltage, and a third supply voltage to one or more RFFE modules, taking into account specific switching circuits and power paths. As an alternative to the first or second supply voltage, any suitable configuration for performing the function of providing a third supply voltage to the RFFE module may be used. This may also apply when the third supply voltage is separate from or provided by a different power supply / module than the power supply / module providing the first and second supply voltages.

[0055] A third supply voltage (273) from a third power source (230) may be provided to a power supply circuit (250) via a third power path (293). For example, the third power path (293) may include a first portion (293-1) connected to a first switching circuit (261), a second portion (293-2) connected to a second switching circuit (262), and a third portion (293-3) connected to a third power source (230). For example, the third supply voltage (273) may be transmitted to the first portion (293-1) and / or the second portion (293-2) via the third portion (293-3). In one embodiment, when the power supply circuit (250) is implemented as a single module, the first part (293-1) may be connected to the first switching circuit (261) via the first capacitor port of the module, and the second part (293-2) may be connected to the second switching circuit (262) via the second capacitor port of the module. The third APT capacitor (283) may be electrically connected to the third power path (293). The third APT capacitor (283) may be used to stably provide the third supply voltage (273). For example, when the first power path (291) and the third power path (293) are connected by the first switching circuit (261), the third supply voltage (273) of the third power source (230) may be provided to the RFFE module (240) via the third power path (293) and the first power path (291). The third supply voltage (273) may be affected by capacitors (e.g., the third APT capacitor (283)) connected on the electrical path to the third power path (293) and the first power path (291). For example, in order to maintain a stable voltage for a high-output signal, a high-capacitance capacitance (e.g., the third APT capacitor (283) has a capacitance of about 4.7 uF) may be required.For example, when the second power path (292) and the third power path (293) are connected by the second switching circuit (262), the third supply voltage (273) of the third power source (230) can be provided to the RFFE module (240) through the third power path (293) and the second power path (292). The third supply voltage (273) can be affected by capacitors (e.g., the third APT capacitor (283)) connected on the electrical path to the third power path (293) and the second power path (292). For example, in order to maintain a stable voltage for a high-output signal, a high-capacity capacitance (e.g., the third APT capacitor (283) has a capacitance of about 4.7 uF) may be required.

[0056] The provision of the third supply voltage may not include an inductor (e.g., it may be provided directly from a battery or envelope tracking power supply) and / or may include capacitors of different values. Consequently, the third supply voltage may be provided at a higher current than the first and / or second supply voltages. Consequently, by using the third supply voltage, one or more of the aforementioned problems may be solved.

[0057] While the above implementation includes a single RFFE module, as will be described in more detail below, the electronic device may include any number of RFFE modules and various switching circuit arrangements in the power supply circuitry 250 and / or may use one or more RFFE modules to provide one or more first, second or third supply voltages to the RFFE modules.

[0058] If the first power supply circuit (251) or the second power supply circuit (252) is damaged and difficult to use, or the current tolerance is exceeded, the third power supply (230) can be used. For example, the third power supply (230) can correspond to the battery (288). The third supply voltage (273) is the voltage (V) provided from the battery (288). bat ) may be. For example, the third power supply (230) may correspond to a third power supply circuit (not shown) that is distinct from the first power supply circuit (251) and the second power supply circuit (252). The third supply voltage (273) may be a voltage provided from the third power supply circuit. The third power supply circuit may take any suitable form, such as an APT power supply, a direct supply from a battery, an envelope tracking power supply, or a predetermined power supply (e.g., a constant voltage or one of several constant voltages).

[0059] The third supply voltage (273) may replace the first supply voltage (271), the second supply voltage (272), or both the first supply voltage (271) and the second supply voltage (272). For example, if the first power supply circuit (251) is difficult to use (e.g., damage to the first power circuit (251), exceeding the allowable current (e.g., the first power supply circuit cannot supply sufficient current), or generating audible noise), the first switching circuit (261) may operate in a closed state and the second switching circuit (262) may operate in an open state. The first switching circuit (261) may be controlled to electrically connect the first power path (291) and the third power path (293) in the closed state. Instead of the first supply voltage (271), a third supply voltage (273) may be provided to the RFFE module (240) through the first power path (291). While the third supply voltage (273) is provided, a second supply voltage (272) may be provided to the RFFE module (240) or another RFFE module (not shown) through the second power path (292). For example, if the use of the second power supply circuit (252) is difficult (e.g., damage to the second power circuit (252), excess of the allowable current (i.e., the second power supply circuit cannot supply sufficient current), or generation of audible noise), the first switching circuit (261) may operate in an open state and the second switching circuit (262) may operate in a closed state. The second switching circuit (262) may be controlled to electrically connect the second power path (292) and the third power path (293) in the closed state. A third supply voltage (273) may be provided to the RFFE module (240) instead of the second supply voltage (272) via the second power path (292). While the third supply voltage (273) is provided, the first supply voltage (271) may be provided to the RFFE module (240) or another RFFE module (not shown) via the first power path (291).For example, if it is difficult to use both the first power supply circuit (251) and the second power supply circuit (252), both the first switching circuit (261) and the second switching circuit (262) can operate in a closed state. Instead of the first supply voltage (271), the third supply voltage (273) can be provided to the RFFE module (240) or another RFFE module (not shown) through the first power path (291). Similarly, instead of the second supply voltage (272), the third supply voltage (273) can be provided to the RFFE module (240) or another RFFE module (not shown) through the second power path (292).

[0060] Hereinafter, the present disclosure describes an example in which a supply voltage (e.g., a first supply voltage (271) or a second supply voltage (272)) according to APT is provided from a first power supply circuit (251) and / or a second power supply circuit (252), but embodiments of the present disclosure are not limited thereto. It may also be understood as an embodiment of the present disclosure that a third power source (230) is connected to a switching circuit (e.g., a first switching circuit (261) or a second switching circuit (262)) of a power supply circuit in which a supply voltage is provided according to a method other than APT (e.g., envelope tracking (ET)).

[0061] FIG. 3 illustrates an example of an electronic device (e.g., electronic device (101)) including a power supply circuit (e.g., power supply circuit (250)) and RFFE modules. FIG. 3 illustrates an example of providing a supply voltage (e.g., a third supply voltage (273)) of a separate power source (e.g., a third power source 230)) to the RFFE module through switching circuits (e.g., a first switching circuit (261) or a second switching circuit (262)) of the power supply circuit (250). The same reference numbers may be used for the same description.

[0062] Referring to FIG. 3, the electronic device (101) may include a processor (210), an RF transceiver (220), a first RFFE module (240), a second RFFE module (340), a power supply circuit (250), and an antenna (not shown) (e.g., antenna (299) of FIG. 2). The second RFFE module (340) may include a power amplifier (PA) (e.g., PA (344)). For each component, the descriptions of FIG. 2 may be referred to.

[0063] The electronic device (101) may include various RFFE modules. To effectively provide a supply voltage to a power amplifier of each RFFE module, at least some of the RFFE modules may include a switching circuit. Through the switching circuit, the supply voltage provided to the power amplifier of the RFFE module may be varied. For example, the first RFFE module (240) may include a third switching circuit (370). The third switching circuit (370) may be configured to selectively electrically connect the first power path (291) or the second power path (292) to the PA (244). For example, the second RFFE module (340) may include a fourth switching circuit (380). The fourth switching circuit (380) may be configured to selectively electrically connect the fourth power path (321) or the fifth power path (322) to the PA (344). The fourth power path (321) may be connected to the first power supply circuit (251) and the first switching circuit (261). For example, the fourth power path (321) may represent a path along which the first supply voltage (271) from the first power supply circuit (251) is transmitted to the second RFFE module (340). For example, the fourth power path (321) may be branched from a node of the first power path (291). For example, the fourth power path (321) may be electrically connected to the first output port (331) of the power supply circuit (250). The first output port (331) may be connected to the first power supply circuit (251) and the first switching circuit (261). The fifth power path (322) may be connected to the second power supply circuit (252) and the second switching circuit (262). For example, the fifth power path (322) may represent a path along which the second supply voltage (272) from the second power supply circuit (252) is transmitted to the second RFFE module (340). For example, the fifth power path (322) may branch from one node of the second power path (292).For example, the fifth power path (322) may be electrically connected to a second output port (332) of a power supply circuit (250). The second output port (332) may be connected to a second power supply circuit (252) and a second switching circuit (262).

[0064] When the electronic device (101) performs communication according to DC (dual connectivity) or performs UL MIMO operation, two or more RFFE modules may be activated. Supply voltages may be provided to power amplifiers of the two or more RFFE modules. For example, the first PA (244) of the first RFFE module (240) and the second PA (344) of the second RFFE module (340) may be activated. Supply voltages may be provided to the first PA (244) and the second PA (344), respectively. Under the control of the processor (210) or the RF transceiver (220), the third switching circuit (370) and the fourth switching circuit (380) may operate. For example, as illustrated in FIG. 3, the second power path (292) may be electrically connected to the first PA (244) through the third switching circuit (370). The second supply voltage (272) of the second power supply circuit (252) may be provided to the first PA (244) through the second power path (292), or the third supply voltage (273) of the third power source (230) may be provided through the third power path (293) and the second power path (292). A fourth power path (321) may be electrically connected to the second PA (344) through the fourth switching circuit (380). The first supply voltage (271) of the first power supply circuit (251) may be provided to the second PA (344) through the fourth power path (321), or the third supply voltage (273) of the third power source (230) may be provided through the third power path (293) and the fourth power path (321).

[0065] For another example, a path arrangement different from that illustrated in FIG. 3 may be configured. A first power path (291) may be electrically connected to the first PA (244) via a third switching circuit (370). The first supply voltage (271) of the first power supply circuit (251) may be provided to the first PA (244) via the first power path (291), or the third supply voltage (273) of the third power source (230) may be provided via the third power path (293) and the first power path (291). A fifth power path (322) may be electrically connected to the second PA (344) via a fourth switching circuit (380). The second supply voltage (272) of the second power supply circuit (252) may be provided to the second PA (344) via the fifth power path (322), or the third supply voltage (273) of the third power source (230) may be provided via the third power path (293) and the fifth power path (322).

[0066] In one embodiment, the third supply voltage (273) may replace the first supply voltage (271), the second supply voltage (272), or both the first supply voltage (271) and the second supply voltage (272). For example, if the first power supply circuit (251) is unusable (e.g., damage to the first power circuit (251), excess of the allowable current, or generation of audible noise), the first switching circuit (261) may operate in a closed state and the second switching circuit (262) may operate in an open state. The first switching circuit (261) may be controlled to electrically connect the first power path (291) and the third power path (293). The third supply voltage (273) may be provided to the second PA (344) of the second RFFE module (340) instead of the first supply voltage (271) through the first power path (291). While the third supply voltage (273) is provided to the second PA (344) of the second RFFE module (304), the second supply voltage (272) may be provided to the first PA (244) of the first RFFE module (240) through the second power path (292). For example, when the use of the second power supply circuit (252) is difficult (e.g., damage to the second power circuit (252), excess of the allowable current, or generation of audible noise), the first switching circuit (261) may be operated in an open state and the second switching circuit (262) may be operated in a closed state. The second switching circuit (262) may be controlled to electrically connect the second power path (292) and the third power path (293). A third supply voltage (273) may be provided to the first PA (244) of the first RFFE module (240) instead of the second supply voltage (272) via the second power path (292). While the third supply voltage (273) is provided to the first RFFE module (240), the first supply voltage (271) may be provided to the second PA (344) of the second RFFE module (340) via the first power path (291).For example, if it is difficult to use both the first power supply circuit (251) and the second power supply circuit (252), both the first switching circuit (261) and the second switching circuit (262) can operate in a closed state. Instead of the first supply voltage (271), the third supply voltage (273) can be provided to the second PA (344) of the second RFFE module (340) through the first power path (291). Similarly, instead of the second supply voltage (272), the third supply voltage (273) can be provided to the first PA (244) of the first RFFE module (240) through the second power path (292). As described above and illustrated in FIG. 3, any one of the first supply voltage, the second supply voltage, and the third supply voltage can be provided to each of the first RFFE (240) and the second RFFE (340) thanks to the first switching circuit (261) and the second switching circuit (262), and additionally any one of the first supply voltage, the second supply voltage, and the third supply voltage can be provided to each of the first PA (244) and the second PA (344) thanks to the third switching circuit (270) and the fourth switching circuit (380).

[0071] The power supply circuit (250) can be configured to supply power to a plurality of RFFE modules (e.g., a first RFFE module (240), a second RFFE module (340), a third RFFE module (443), a fourth RFFE module (444), and a fifth RFFE module (445)). The power supply circuit (250) can provide a plurality of supply voltages for the plurality of RFFE modules. The power supply circuit (250) can provide a supply voltage to each RFFE module of the plurality of RFFE modules.

[0072] Various supply voltages may be provided to each RFFE module (or PA of the RFFE module) in various ways. A first supply voltage (271) may be provided to a first RFFE module (240), a second RFFE module (340), a fourth RFFE module (444), and / or a fifth RFFE module (445).

The first switching circuit is configured to connect the first power path to the third power path to provide the third supply voltage to the first power amplifier while the first supply voltage is not provided to the power amplifier via the first power path during operation of the first power amplifier. While the first power amplifier is operating and the second supply voltage is not provided to the power amplifier through the second power path, the second switching circuit is configured to connect the second power path to the third power path to provide the third supply voltage to the first power amplifier.

[0124] For example, the first switching circuit is controllable to disconnect the first power path from the third power path while the first supply voltage is provided to the first power amplifier through the first power path during operation of the first power amplifier. The second switching circuit is configured to disconnect the second power path from the third power path while the second supply voltage is provided to the first power amplifier through the second power path during operation of the first power amplifier.

[0125] For example, the third supply voltage is provided from a battery of the electronic device or from a third power circuit different from the first power circuit and the second power circuit.

[0126] For example, the first RFFE module includes a third switching circuit. The third switching circuit is configured to connect the first power amplifier to the first power path when in the first state, and to connect the first power amplifier to the second power path when in the second state.

The third RFFE module is configured to process a signal in a frequency band of a second frequency range lower than the first frequency range. The fourth RFFE module is configured to process a signal in a frequency band for evolved universal terrestrial radio access (E-UTRA)-new radio (NR) (EN)-dual connectivity (DC). The fifth RFFE module is configured to process a signal in a frequency band of a third frequency range lower than the first frequency range and higher than the second frequency range.

[0134] For example, the first frequency range includes a frequency band of about 3.4 GHz or higher. The second frequency range includes a frequency band of about less than 1 GHz.
