Technology Field

[0001] An embodiment of the present disclosure relates to an electronic device for preventing malfunction of an antenna switching module. Background Technology

[0003] With the advancement of wireless communication technology, electronic devices (e.g., communication electronic devices) are being widely used in daily life, and consequently, the demand for wireless data traffic is on the rise. Since the commercialization of 4G (4th generation) communication systems (e.g., LTE (long term evolution)), communication systems that transmit and / or receive signals using high-frequency bands (e.g., mmWave, approximately 3 GHz to 300 GHz band) (e.g., 5G (5th generation), pre-5G communication systems, or new radio (NR)) are being researched to meet the increasing demand for wireless data traffic.

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

[0006] If the electronic device supports multiple frequency bands and / or multiple communication methods (e.g., 2G (generation), 3G, LTE (long term evolution) and / or NR (new radio)), it can connect the communication path of the frequency band used for wireless communication and the antenna using an antenna switching module (e.g., ASM (antenna switching module)) of the RFFE (radio frequency front end). The antenna switching module may include multiple series switches corresponding to the communication paths of the multiple frequency bands supported by the electronic device and at least one shunt switch corresponding to at least one antenna used for wireless communication by the electronic device.

[0007] When the electronic device performs wireless communication using a first frequency band through a first antenna, it may enable (or turn ON) a series switch corresponding to the first frequency band in the antenna switching module and disable (or turn OFF) a shunt switch connected to the first antenna. The electronic device may disable a series switch corresponding to the remaining frequency bands excluding the first frequency band in the antenna switching module and enable a shunt switch connected to the remaining antennas excluding the first antenna.

[0008] If the series switch and shunt switch of the antenna switching module are simultaneously activated due to an error in the control signal for controlling the antenna switching module, the insertion loss of the circuit increases, which may cause data transmission and reception to be interrupted or the current consumption of the electronic device to increase momentarily.

[0009] An embodiment of the present invention discloses a device for preventing malfunction of an antenna switching module in an electronic device.

[0010] The technical problems to be solved in this document are not limited to those mentioned above, and other technical problems not mentioned will be clearly understood by those skilled in the art to which this invention belongs from the description below.

[0012] According to one embodiment, the electronic device may include at least one antenna, a communication circuit supporting a plurality of frequency bands, an antenna switching module that electrically connects the communication circuit and at least one antenna using a plurality of switching circuits, a control device that controls a plurality of switching circuits included in the antenna switching module, and at least one processor. According to one embodiment, the control device may output a first control signal for controlling a first switching circuit among a plurality of switching circuits based on an input signal for controlling the antenna switching module received from the processor, and may output a second control signal for controlling a second switching circuit among a plurality of switching circuits based on the input signal and the first control signal.

[0013] According to one embodiment, the electronic device may include at least one antenna, a communication circuit supporting a plurality of frequency bands, an antenna switching module that electrically connects the at least one antenna to an electrical path of a communication circuit corresponding to each of the plurality of frequency bands using a plurality of switching circuits, a plurality of control devices corresponding to the plurality of frequency bands, and at least one processor. According to one embodiment, among the plurality of control devices, a first control device may, when it receives an input signal corresponding to a first frequency band among the plurality of frequency bands from a processor, output a first control signal for controlling a first switching circuit corresponding to the first frequency band among the plurality of switching circuits based on the input signal, and output a second control signal for controlling a second switching circuit corresponding to the first frequency band based on the input signal and the first control signal. According to one embodiment, among a plurality of control devices, a second control device may, upon receiving an input signal corresponding to a second frequency band among a plurality of frequency bands from a processor, output a first control signal for controlling a third switching circuit corresponding to the second frequency band among a plurality of switching circuits based on the input signal, and output a second control signal for controlling a fourth switching circuit corresponding to the second frequency band based on the input signal and the first control signal.

[0015] According to an embodiment of the present invention, when an electronic device supports a plurality of frequency bands, a control signal corresponding to each switching circuit (e.g., a series switch or a shunt switch) included in an antenna switching module is sequentially generated and provided to each switching circuit, thereby preventing a situation in which the switching circuits included in the antenna switching module are simultaneously activated.

For example, the electronic device (101) of FIG. 2 may be at least partially similar to the electronic device (101) of FIG. 1, or may include other embodiments of the electronic device. In the following description, the electronic device (101) may be assumed to have a communication circuit (210) that includes three electrical paths (212, 214, and 216) corresponding to three frequency bands. However, the electronic device (101) may be substantially applicable even if it includes multiple communication paths (or two or more communication paths) corresponding to multiple frequency bands (or two or more frequency bands).

[0050] According to one embodiment with reference to FIG. 2, the electronic device (101) may include at least one of a processor (200), a communication circuit (210), a control unit (220), an antenna switching module (230), or an antenna (240). For example, the processor (200) may be substantially identical to the processor (120) of FIG. 1 (e.g., an application processor and / or a communication processor) or may include the processor (120). At least one of the communication circuit (210), the control unit (220), the antenna switching module (230), or the antenna (240) may be substantially identical to the wireless communication module (192) of FIG. 1 or may include the wireless communication module (192). For example, the processor (200) may be operatively, functionally, or electrically connected to at least one of the communication circuit (210), the control unit (220), the antenna switching module (230), or the antenna (240). For example, the processor (300) may include at least one processor including a processing circuit. For example, the antenna (240) may include at least one antenna.

[0051] According to one embodiment, the processor (200) can perform various operations related to wireless communication of the electronic device (101). For example, the processor (200) can generate a signal (e.g., a baseband signal) to be transmitted to an external device via the antenna (240) and output it to the communication circuit (210). For example, the processor (200) can decode (or restore) a signal received from an external device via the antenna (240) and the communication circuit (210).

[0052] According to one embodiment, the processor (200) may provide a control signal to the control device (220) for an electrical connection between an antenna (240) and an electrical path (or communication path) (212, 214 and / or 216) corresponding to each frequency band supported by the electronic device (101). For example, when the processor (200) supports communication of a first frequency band, a second frequency band, and a third frequency band through the antenna (240), it may provide a control signal to the control device (220) for an electrical connection between an antenna (240) and an electrical path (212, 214 and / or 216) corresponding to each frequency band. For example, when the processor (200) performs wireless communication using the first frequency band, it may provide a first input signal to the control device (220) to control the electrical path (212) corresponding to the first frequency band and the antenna (240) to be electrically connected. For example, the processor (200) may provide a second input signal to the control device (220) to control the electrical connection between the electrical path (214) and the antenna (240) corresponding to a second frequency band not used for wireless communication to be disconnected. The processor (200) may provide a second input signal to the control device (220) to control the electrical connection between the electrical path (216) and the antenna (240) corresponding to a third frequency band not used for wireless communication to be disconnected. For example, the first input signal and the second input signal may be transmitted to the control device (220) via a mobile industry processor interface (MIPI). For example, the first input signal may represent a signal (e.g., a low signal) containing a value (or information, command) indicating the electrical connection between the electrical path and the antenna (240) corresponding to the frequency band.For example, the second input signal may represent a signal (e.g., a high signal) containing a value (or information, command) indicating the disconnection of the electrical path corresponding to the frequency band and the electrical connection of the antenna (240).

[0053] According to one embodiment, the communication circuit (210) may perform various processing to output a signal (e.g., a baseband signal) received from the processor (200) through the antenna (240). For example, the various processing may include at least one of converting the baseband signal into a radio frequency (RF) band signal, modulating the signal, or amplifying the signal. For example, the communication circuit (210) may include at least a portion of a radio frequency integrated circuit (RFIC) and / or a radio frequency front end (RFFE).

[0054] For example, the communication circuit (210) can convert a baseband signal provided by the processor (200) into a signal of at least one frequency band used for wireless communication among a plurality of frequency bands supported by the electronic device (101) (e.g., RF signal). The communication circuit (210) can amplify the signal converted to at least one frequency band used for wireless communication (e.g., RF signal). The communication circuit (210) can output the amplified signal through a port (e.g., a first port of the first frequency band) corresponding to at least one frequency band used for wireless communication (e.g., a first frequency band) among the ports corresponding to each of the plurality of frequency bands supported by the electronic device.

[0055] According to one embodiment, the communication circuit (210) can perform various processing on a signal (e.g., RF signal) received through the antenna (240). For example, the various processing may include at least one of converting the RF band signal to a baseband signal, demodulating the signal, or low-noise amplification of the signal.

[0056] For example, the communication circuit (210) can perform low-noise amplification on a signal (e.g., RF signal) received through the antenna (240). The communication circuit (210) can convert the low-noise amplified signal into a baseband signal and transmit it to the processor (200).

[0057] According to one embodiment, the control device (220) can generate a control signal for controlling a plurality of switching circuits included in the antenna switching module (230) based on an input signal (e.g., a first input signal or a second input signal) received from the processor (200) and provide it to the antenna switching module (230).

[0058] For example, when the control device (220) receives a first input signal corresponding to a first frequency band used for wireless communication from the processor (200), it may generate a control signal (e.g., a first control signal and a second control signal) for electrically connecting a first port corresponding to the first frequency band and an antenna (240) in the communication circuit (210) through a first electrical path (212) and provide it to the antenna switching module (230). For example, based on the first input signal received from the processor (200), the control device (220) may generate a first control signal for controlling (e.g., deactivating) a first switching circuit (e.g., a shunt switch) among a plurality of switching circuits corresponding to the first frequency band in the antenna switching module (230) and provide it to the first switching circuit. A control device (220) may generate a second control signal for controlling (e.g., enabling) a second switching circuit (e.g., series switch) among a plurality of switching circuits corresponding to a first frequency band in an antenna switching module (230) based on a first input signal and a first control signal provided by a processor (200), and provide the second switching circuit. For example, the first control signal may represent a signal containing a value (or information) for controlling the activation or deactivation of a first switching circuit set based on an input signal (e.g., first input signal or second input signal) provided by the control device (220) from the processor (200). For example, the second control signal may represent a signal containing a value (or information) for controlling the activation or deactivation of a second switching circuit set based on an input signal (e.g., first input signal or second input signal) provided by the control device (220) from the processor (200) and the first control signal.

[0059] For example, when the control device (220) receives a second input signal corresponding to a second frequency band not used for wireless communication from the processor (200), it may generate a control signal (e.g., a first control signal and a second control signal) to disconnect the electrical connection between the second port corresponding to the second frequency band and the antenna (240) in the communication circuit (210) and provide it to the antenna switching module (230). For example, based on the second input signal received from the processor (200), the control device (220) may generate a first control signal for controlling (e.g., deactivating) a first switching circuit (e.g., a series switch) among a plurality of switching circuits corresponding to the second frequency band in the antenna switching module (230) and provide it to the first switching circuit. The control device (220) can generate a second control signal for controlling (e.g., enabling) a second switching circuit (e.g., shunt switch) among a plurality of switching circuits corresponding to a second frequency band in the antenna switching module (230) based on a second input signal and a first control signal received from the processor (200), and provide it to the second switching circuit.

[0060] For example, when the control device (220) receives a second input signal corresponding to a third frequency band not used for wireless communication from the processor (200), it may generate a control signal (e.g., a first control signal and a second control signal) to disconnect the electrical connection between the third port corresponding to the third frequency band and the antenna (240) in the communication circuit (210) and provide it to the antenna switching module (230). For example, based on the second input signal received from the processor (200), the control device (220) may generate a first control signal for controlling (e.g., deactivating) a first switching circuit (e.g., a series switch) among a plurality of switching circuits corresponding to the second frequency band in the antenna switching module (230) and provide it to the first switching circuit. The control device (220) can generate a second control signal for controlling (e.g., enabling) a second switching circuit (e.g., shunt switch) among a plurality of switching circuits corresponding to a second frequency band in the antenna switching module (230) based on a second input signal and a first control signal received from the processor (200), and provide it to the second switching circuit.

[0061] According to one embodiment, the antenna switching module (230) can electrically connect the communication circuit (210) and the antenna (240) through an electrical path (or communication path) (212, 214 and / or 216) corresponding to the frequency band used for wireless communication in the electronic device (101) through a plurality of switching circuits. For example, the plurality of switching circuits may include a plurality of series switches corresponding to each of the plurality of frequency bands supported by the electronic device (101) and a shunt switch connected to the antenna (240). For example, the switching circuit may include a tunable circuit.

[0062] For example, the antenna switching module (230) can activate (e.g., enable or ON) a series switch corresponding to a first frequency band used for wireless communication and deactivate (e.g., disable or OFF) a shunt switch connected to the antenna (240) based on control signals (e.g., a first control signal and a second control signal) provided by the control device (220). For example, the shunt switch may be deactivated based on the first control signal and the series switch may be activated based on the second control signal. For example, the series switch may be activated based on the first control signal and the shunt switch may be deactivated based on the second control signal. For example, activation of the series switch may include a series of operations to electrically connect the communication circuit (210) and the antenna (240) through an electrical path (212, 214 and / or 216). For example, deactivating the shunt switch may include a series of operations to release the electrical connection between the electrical path (212, 214 and / or 216) between the communication circuit (210) and the antenna (240) and the termination. For example, the termination may include a resistance of a specified value (e.g., about 50 Ω).

[0063] For example, the antenna switching module (230) may disable (e.g., disable or OFF) a series switch corresponding to a second frequency band not used for wireless communication and enable (e.g., enable or ON) a shunt switch connected to the antenna (240) based on control signals (e.g., a first control signal and a second control signal) provided by the control device (220). For example, the series switch may be disabled based on the first control signal and the shunt switch may be enabled based on the second control signal. For example, the shunt switch may be enabled based on the first control signal and the series switch may be disabled based on the second control signal. For example, disabling the series switch may include a series of operations to disconnect the electrical connection between the communication circuit (210) and the antenna (240). For example, activation of the shunt switch may include a series of operations connecting the electrical path (212, 214 and / or 216) between the communication circuit (210) and the antenna (240) and the termination.

[0064] For example, the antenna switching module (230) can disable (e.g., disable or OFF) a series switch corresponding to a third frequency band not used for wireless communication and enable (e.g., enable or ON) a shunt switch connected to the antenna (240) based on control signals (e.g., a first control signal and a second control signal) provided by the control device (220). For example, the series switch may be disabled based on the first control signal and the shunt switch may be enabled based on the second control signal. For example, the shunt switch may be enabled based on the first control signal and the series switch may be disabled based on the second control signal.

[0065] For example, the antenna switching module (230) may include an additional control device for controlling a shunt switch connected to the antenna (240). The additional control device may generate a third control signal to disable the shunt switch connected to the antenna (240) regardless of an activation signal corresponding to the remaining frequency bands when a deactivation signal corresponding to one of the multiple frequency bands is received from the control device (220). For example, the additional control device may generate a third control signal to disable the shunt switch connected to the antenna (240) regardless of an activation signal corresponding to the second frequency band and / or an activation signal corresponding to the third frequency band when a deactivation signal corresponding to the first frequency band for the shunt switch connected to the antenna (240) is received from the control device (220). For example, the additional control device may generate a third control signal to enable the shunt switch connected to the antenna (240) when an activation signal corresponding to multiple frequency bands is received from the control device (220). For example, the additional control device may include a flip-flop. For example, the third control signal may represent a signal containing a value (or information) for the additional control device to control a shunt switch based on a control signal (e.g., an enable signal and / or an disable signal) corresponding to a plurality of frequency bands.

[0066] According to one embodiment, the electronic device (101) can transmit a signal corresponding to at least one frequency band through the antenna (240) to an external device through at least one electrical path connected to the antenna (240) by an antenna switching module (230).

The antenna switching module (230) may include a plurality of switching circuits, such as a series switch (310) and a shunt switch (320). For example, the series switch (310) may include a second type of transistor. For example, the shunt switch (320) may include a second type of transistor and / or an inductor. For example, the second type of transistor may include a P-channel type (e.g., NMOS) transistor.

[0070] According to one embodiment, a series switch (310) of an antenna switching module (230) may be placed on a first electrical path (212) between a port of a first frequency band of a communication circuit (210) and an antenna (240) (or antenna port). The series switch (310) may selectively connect the communication circuit (210) and the antenna (240) through the first electrical path (212) based on a control signal (e.g., a first control signal or a second control signal) provided by a control device (220). For example, the series switch (310) may electrically connect the communication circuit (210) and the antenna (240) through the first electrical path (212) when an activation signal is received from the control device (220). The series switch (310) may disconnect the electrical connection between the communication circuit (210) and the antenna (240) when an deactivation signal is received from the control device (220).

[0071] According to one embodiment, a shunt switch (320) of an antenna switching module (230) may be placed on an electrical path between a first point (321) on a first electrical path (212) between a port of the first frequency band of the communication circuit (210) and the antenna (240) (or antenna port) and a termination. The shunt switch (320) may selectively connect the first electrical path (212) between the communication circuit (210) and the antenna (240) and the termination based on a control signal provided by a control device (220). For example, the shunt switch (320) may electrically connect the first electrical path (212) between the communication circuit (210) and the antenna (240) and the termination when an activation signal is received from the control device (220). The shunt switch (320) can disconnect the electrical connection between the first electrical path (212) between the communication circuit (210) and the antenna (240) and the termination when a deactivation signal is received from the control device (220). For example, the termination may include a resistance of a specified value (e.g., about 50 Ω).

[0072] According to one embodiment, when power is applied, the level shifter (300) can output a first voltage value (e.g., - voltage value) and a second voltage value (e.g., + voltage value) to a control signal generating device (302).

[0073] According to one embodiment, a control signal generating device (302) can generate a control signal for controlling a plurality of switching circuits included in an antenna switching module (230) based on an input signal (e.g., a first input signal or a second input signal) provided from a processor (200) and a voltage value provided from a level shifter (300). For example, the control signal generating device (302) may include a first control signal generating device (400) and a second control signal generating device (410), as shown in FIG. 4. For example, the first input signal may represent a signal (e.g., a low signal) containing a value (or information, command) indicating an electrical connection between an electrical path corresponding to a frequency band and an antenna (240). For example, the second input signal may represent a signal (e.g., a high signal) containing a value (or information, command) indicating the disconnection of an electrical connection between an electrical path corresponding to a frequency band and an antenna (240).

[0074] For example, the first control signal generating device (400) may include a first type first transistor (402), a second type second transistor (404), and a first type third transistor (406). The first transistor (402) and the second transistor (404) may be driven based on an input signal (e.g., a first input signal or a second input signal) provided by the processor (200). For example, the driving of the transistor may include a series of operations that are activated or deactivated based on an input signal provided by the processor (200). When the first transistor (402) is activated based on a first input signal provided by the processor (200), it may output a first voltage value (e.g., a - voltage value) provided by the level shifter (300). When the second transistor (404) is activated based on a second input signal provided by the processor (200), it can output a second voltage value (e.g., a + voltage value) provided by the level shifter (300). The third transistor (406) is connected to the output terminal of the first transistor (402) and the output terminal of the second transistor (404), and can be driven (e.g., activated) based on a control signal generated by the second control signal generating device (410). For example, the first type of transistor may include an N-channel type transistor (e.g., PMOS). For example, the second type of transistor may include a P-channel type transistor (e.g., NMOS).

[0075] For example, the second control signal generating device (410) may include a first type fourth transistor (412), a second type fifth transistor (414), and a first type sixth transistor (416). The fourth transistor (412) and the fifth transistor (414) may be driven based on an input signal (e.g., a first input signal or a second input signal) provided by the processor (200). For example, the driving of the transistors may include a series of operations that are activated or deactivated based on an input signal provided by the processor (200). When the fourth transistor (412) is activated based on a first input signal provided by the processor (200), it may output a second voltage value (e.g., a + voltage value) provided by the level shifter (300). When the fifth transistor (414) is activated based on a second input signal provided by the processor (200), it can output a first voltage value (e.g., - voltage value) provided by the level shifter (300). The sixth transistor (416) is connected to the output terminal of the fourth transistor (412) and the output terminal of the fifth transistor (414), and can be driven (e.g., activated) based on a control signal generated by the first control signal generating device (400).

[0076] According to one embodiment, a control signal generating device (302) can generate a first control signal for controlling a first switching circuit (e.g., a series switch (310) or a shunt switch (320)) of an antenna switching module (230) through a first control signal generating device (400) based on an input signal (e.g., a first input signal or a second input signal) provided by a processor (200). A second control signal generating device (410) of the control signal generating device (302) can generate a second control signal for controlling a second switching circuit (e.g., a shunt switch (320) or a series switch (310)) of an antenna switching module (230) based on an input signal provided by the processor (200) and the first control signal. For example, the first control signal may represent a signal including a value (or information) for controlling the activation or deactivation of a first switching circuit set based on an input signal (e.g., a first input signal or a second input signal) provided by the control signal generating device (302) from the processor (200). For example, the second control signal may represent a signal including a value (or information) for controlling the activation or deactivation of a second switching circuit set based on an input signal (e.g., a first input signal or a second input signal) provided by the control signal generating device (302) from the processor (200) and the first control signal.

[0077] For example, when the control signal generating device (302) receives a first input signal (e.g., a low signal) corresponding to a first frequency band used for wireless communication from the processor (200), as shown in FIG. 6, the first transistor (402) of the first control signal generating device (400) and the fourth transistor (412) of the second control signal generating device (410) may be activated based on the first input signal, and the second transistor (404) of the first control signal generating device (400) and the fifth transistor (414) of the second control signal generating device (410) may be deactivated. The first control signal generating device (400) may output a first control signal (e.g., a low signal) (600) based on a first voltage value (e.g., a - voltage value) applied to the input terminal of the activated first transistor (402). The sixth transistor (416) of the second control signal generating device (410) may be activated by a first control signal (e.g., low signal) (600) provided by the first control signal generating device (400). The shunt switch (320) of the antenna switching module (230) may be deactivated by a first control signal (e.g., low signal) (600) provided by the first control signal generating device (400). For example, deactivation of the shunt switch (320) may include a series of operations to disconnect the electrical path (212, 214 and / or 216) between the communication circuit (210) and the antenna (240) and the electrical connection of the terminal.

[0078] The second control signal generating device (410) can output a second control signal (e.g., a high signal) (610) based on a second voltage value (e.g., a + voltage value) applied to the input terminal of the fourth transistor (412) that is activated when the sixth transistor (416) is activated. The series switch (310) of the antenna switching module (230) can be activated by the second control signal (e.g., a high signal) (610) provided by the second control signal generating device (410). The antenna switching module (230) can electrically connect the first port of the communication circuit (210) and the antenna (240) through the first electrical path (212) using the shunt switch (320) that is deactivated based on the first control signal (600) and the series switch (310) that is activated based on the second control signal (610). The electronic device (101) can transmit a signal of the first frequency band to an external device through the first electrical path (212) between the first port of the communication circuit (210) and the antenna (240).

[0079] For example, when the control signal generating device (302) receives a second input signal (e.g., a high signal) corresponding to a first frequency band not used for wireless communication from the processor (200), as shown in FIG. 5, the first transistor (402) of the first control signal generating device (400) and the fourth transistor (412) of the second control signal generating device (410) may be deactivated based on the second input signal, and the second transistor (404) of the first control signal generating device (400) and the fifth transistor (414) of the second control signal generating device (410) may be activated. The second control signal generating device (410) may output a first control signal (e.g., a low signal) (500) based on a first voltage value (e.g., a - voltage value) applied to the input terminal of the activated fifth transistor (414). The third transistor (406) of the first control signal generating device (400) can be activated by a first control signal (e.g., low signal) (500) provided by the second control signal generating device (410). The series switch (310) of the antenna switching module (230) can be deactivated by a first control signal (e.g., low signal) (500) provided by the second control signal generating device (410).

[0080] The first control signal generating device (400) can output a second control signal (e.g., high signal) (510) based on a second voltage value (e.g., + voltage value) applied to the input terminal of the second transistor (404) that is activated when the third transistor (406) is activated. The shunt switch (320) of the antenna switching module (230) can be activated by the second control signal (e.g., high signal) (510) provided by the first control signal generating device (400). The antenna switching module (230) may not electrically connect the first port of the communication circuit (210) and the antenna (240) by using the series switch (310) that is deactivated based on the first control signal (500) and the shunt switch (320) that is activated based on the second control signal (510).
