For example, the power supply circuit (250) can provide the supply voltage (255) to the power amplifier of the RFFE module (230) based on average power tracking (APT). For example, the power supply circuit (250) can provide the supply voltage (255) to the power amplifier of the RFFE module (230) based on envelope tracking (ET). As a term indicating a voltage (e.g., supply voltage (255)) applied to a power amplifier of an RFFE module (230), in addition to supply voltage, terms such as supply power, amplifier power, operating voltage for a power amplifier, operating power, power amplifier power, and / or terms having equivalent technical / functional meanings may be used.

[0048] Figure 3 is a diagram illustrating a frequency band. The frequency band represents a specific frequency range in the frequency domain. For wireless communication, the electronic device (101) can support various types of frequency bands, and depending on the frequency band, the components of the RFFE module (e.g., RFFE module (230)) for signal processing in the frequency band can vary.

[0049] Referring to FIG. 3, the frequency spectrum may include a first frequency range (321), a second frequency range (322), and / or a third frequency range (323). For example, the first frequency range (321) may be a region including frequencies lower than a first reference value (311) in the frequency domain. For example, the second frequency range (322) may be a region including frequencies higher than the first reference value (311) and lower than the second reference value (312). The second frequency range (322) may be higher than the first frequency range (321). The frequency bands of the second frequency range (322) may be higher than the frequency bands of the first frequency range (321). For example, the third frequency range (323) may be a region including frequencies higher than the second reference value (312). The third frequency range (323) may be higher than the second frequency range (322). The frequency bands of the third frequency range (323) may be higher than the frequency bands of the second frequency range (322).

[0050] In one embodiment, the first frequency range (321) may be a low-band (LB). For example, the first frequency range (321) may represent a frequency range below about 1 GHz. The first frequency range (321) may include one or more low-frequency bands (e.g., the first frequency band (331)). The electronic device (101) may transmit or receive signals on one of the one or more low-frequency bands. For example, the one or more low frequency bands may include a B5 band (FDD (frequency division duplex), DL: 869MHz-894MHz, UL: 824MHz-849MHz), a B8 band (FDD, DL: 925MHz-960MHz, UL: 880MHz-915MHz), or a B26 band (FDD, DL: 859MHz-894MHz, UL: 814MHz-849MHz). As a non-limiting example, depending on the supported wireless access technology (e.g., NR), the terms B5, B8, B26, which designate frequency bands, may also be replaced with n5, n8, n26.

[0051] In one embodiment, the second frequency range (322) may be a mid-band (MB). For example, the second frequency range (322) may represent a frequency range greater than or equal to about 1 GHz and less than or equal to about 2.3 GHz. The second frequency range (322) may include one or more mid-frequency bands (e.g., the second frequency band (332) or the fourth frequency band (334)). The electronic device (101) may transmit or receive signals on one of the one or more mid-frequency bands. For example, the one or more intermediate frequency bands may include a B1 band (FDD, DL: 2110 MHz-2170 MHz, UL: 1920 MHz-1980 MHz), a B3 band (FDD, DL: 1805 MHz-1880 MHz, UL: 1710 MHz-1785 MHz), a B34 band (TDD (time division duplex), 2010 MHz-2025 MHz), or a B39 band (TDD, 1880 MHz-1920 MHz). As a non-limiting example, depending on the supported radio access technology (e.g., NR), terms such as B1, B3, B34, B39, which designate frequency bands, may also be used interchangeably with n1, n3, n34, n39.

[0052] In one embodiment, the third frequency range (323) may be a high-band (HB). For example, the third frequency range (323) may represent a frequency range of about 2.3 GHz or higher. The third frequency range (323) may include one or more high-frequency bands (e.g., the third frequency band (333)). The electronic device (101) may transmit or receive signals on one of the one or more high-frequency bands. For example, the one or more high-frequency bands may include a B7 band (FDD, DL: 2620 MHz-2690 MHz, UL: 2500 MHz-2570 MHz), a B40 band (TDD, 2300 MHz-2400 MHz), and a B41 band (TDD, 2496 MHz-2690 MHz). As a non-limiting example, depending on the supported wireless access technology (e.g., NR), terms such as B7, B40, B41, which designate frequency bands, may be replaced with n7, n40, n41.

[0053] Figures 4a and 4b illustrate the insertion loss characteristics of a diplexer as a function of frequency. Insertion loss represents the amount of loss for a signal passing through a filter at a specified frequency. The graphs indicate that the lower the insertion loss, the better the signal passes through.

[0054] Referring to FIG. 4A, a graph (411) represents an insertion loss of a first port of a diplexer. The first port may be configured to pass frequencies lower than a first designated frequency. The horizontal axis of the graph (411) represents a frequency (unit: MHz (megahertz)), and the vertical axis of the graph (411) represents an insertion loss (unit: dB (decibel)). Referring to the graph (411), a portion of the diplexer connected to the first port may function as a filter (e.g., LPF) for harmonic removal. In one embodiment, when the diplexer is arranged within an RFFE module (e.g., RFFE module (230)), a separate filter (e.g., LPF) for harmonic removal may be omitted within the RFFE module.

[0055] Referring to FIG. 4B, graph (412) represents the characteristics of the second port of the diplexer. The second port may be configured to pass a frequency higher than a second designated frequency. The vertical axis of graph (412) represents a frequency (unit: MHz), and the vertical axis of graph (412) represents an insertion loss (unit: dB). Referring to graph (412), a portion of the diplexer connected to the second port may function as a band pass filter (BPF). Since the diplexer does not pass a frequency higher than a certain level, harmonic components at high frequencies may be reduced and / or eliminated through the diplexer. In one embodiment, when the diplexer is arranged within an RFFE module (e.g., RFFE module (230)), a separate filter (e.g., LPF) for harmonic removal may be omitted within the RFFE module.

[0056] FIG. 5 illustrates an example of an RFFE module (e.g., RFFE module (230)) including a diplexer.

[0057] Referring to FIG. 5, the RFFE module (230) may include power amplifiers (510).

The electronic device (101) may support one or more low frequency bands in the first frequency range. The first transmit switch (521) may be used to select a specific frequency band (e.g., the first frequency band (331)) among the one or more low frequency bands. The first transmit switch (521) may be used to select a path for the specific frequency band in the first frequency range. The electronic device (101) may control the first transmit switch (521) connected to the first power amplifier (511) to select a path for the specific frequency band under the control of the processor (210) and / or the RF transceiver (220). For example, the RFFE module (230) may include a second transmit switch (522). The electronic device (101) may support one or more intermediate frequency bands in the second frequency range. A second transmission switch (522) may be used to select a specific frequency band (e.g., the second frequency band (332)) among the one or more intermediate frequency bands. The second transmission switch (522) may be used to select a path for the specific frequency band in the second frequency range. The electronic device (101) may control the second transmission switch (522) connected to the second power amplifier (512) to select a path for the specific frequency band under the control of the processor (210) and / or the RF transceiver (220). For example, the RFFE module (230) may include a third transmission switch (523). The electronic device (101) may support one or more high frequency bands in the third frequency range. A third transmission switch (523) may be used to select a specific frequency band (e.g., a third frequency band (333)) from among the one or more high frequency bands.A third transmission switch (523) may be used to select a path for the specific frequency band of the third frequency range. The electronic device (101) may control the third transmission switch (523) connected to the third power amplifier (513) to select a path for the specific frequency band under the control of the processor (210) and / or the RF transceiver (220).

The first filter circuit (531) may be used to pass signals of a first frequency band (e.g., the first frequency band (331)) of a first frequency range (321). For example, the first frequency band corresponds to FDD, and the first filter circuit (531) may include a duplexer for distinguishing a transmission frequency and a reception frequency. For example, the RFFE module (230) may include a second filter circuit (532). The second filter circuit (532) may be used to pass signals of a second frequency band (e.g., the second frequency band (332)) of a second frequency range (322). For example, the second frequency band may correspond to FDD, and the second filter circuit (532) may include a duplexer for distinguishing a transmission frequency and a reception frequency. For example, the RFFE module (230) may include a third filter circuit (533). The third filter circuit (533) may be used to pass signals of a third frequency band (e.g., the third frequency band (333)) of the third frequency range (323). For example, the third frequency band may correspond to TDD, and the third filter circuit (533) may include a bandpass filter for the TDD frequency band. For example, the RFFE module (230) may include a fourth filter circuit (534). The fourth filter circuit (534) may be used to pass signals of a fourth frequency band (e.g., the fourth frequency band (334)) of the second frequency range (322).

The first diplexer (561) may be configured to distinguish between signals in a first frequency range (e.g., first frequency range (321), LB) and signals in a second frequency range (e.g., second frequency range (322), MB). For example, one end (or a first port, which may be referred to as a low port) of the first diplexer (561) may be configured to pass signals in a frequency band of the first frequency range, and the other end (or a second port, which may be referred to as a high port) of the first diplexer (561) may be configured to pass signals in a frequency band of the second frequency range. As an example, the first diplexer (561) may include a first filter configured to pass signals in a frequency band of the first frequency range and a second filter configured to pass signals in a frequency band of the second frequency range.

For the first antenna (591) and the second antenna (592), reference may be made to the descriptions of the antenna (290) of FIG. 2. The first antenna (591) may be electrically connected to a first diplexer (561). For example, the RFFE module (230) may have a first diplexer port connected to the first diplexer (561). The first antenna (591) may be electrically connected to the first diplexer port. The second antenna (592) may be electrically connected to the second diplexer (562).

[0074] According to one embodiment, a signal path and an antenna within the RFFE module (230) are always connected to the antenna switching circuit (540), but the electrical connection between the signal path and the antenna can be controlled by the operation of the antenna switching circuit (540). For example, the electronic device (101) can be configured to select an antenna corresponding to a signal path by controlling the electrical connection between the pole and the throw of the antenna switching circuit (540). The antenna switching circuit (540) can be configured to electrically connect an antenna corresponding to a signal path including each filter circuit. For example, the electronic device (101) can control the antenna switching circuit (540) to electrically connect a first signal path (571) and a specific antenna (e.g., a first antenna (591) or a second antenna (592)). For example, the electronic device (101) can control the antenna switching circuit (540) to electrically connect a second signal path (572) and a specific antenna (e.g., a first antenna (591) or a second antenna (592)). For example, the electronic device (101) can control the antenna switching circuit (540) to electrically connect a third signal path (573) and a specific antenna (e.g., a first antenna (591) or a second antenna (592)). For example, the electronic device (101) can control the antenna switching circuit (540) to electrically connect a fourth signal path (574) and a specific antenna (e.g., a first antenna (591) or a second antenna (592)).

[0075] According to one embodiment, one or more frequency bands that can be supported by each antenna may be defined. The supported frequency bands may vary depending on the structural characteristics of the antenna (e.g., physical shape and / or arrangement, or length of the conductive portion). Various types of conductive portions may serve as radiators for the antenna. For example, the metal frame of the electronic device (101) may include a plurality of conductive portions. The conductive portions positioned between the injected non-conductive portions may be used as radiators for the antenna. For another example, the electronic device (101) may include conductive portions in the form of patches. For another example, some surfaces forming slots or slits within a conductor may be used as radiators for the antenna. These conductive portions may be designed to induce resonance of RF signals in a specific frequency band. Furthermore, by changing the location of the feed point or by varying the length of the electrical path, the antenna may support various frequency bands. According to one embodiment, the first antenna (591) of the electronic device (101) may be configured to support frequency bands of a first frequency range (321) and a second frequency range (322). The second antenna (592) of the electronic device (101) may be configured to support frequency bands of a third frequency range (323). The first antenna (591) may be electrically connected to a first diplexer (561). One end of the first diplexer (561) may be electrically connected to a first throw (549a) of an antenna switching circuit (540).

[0076] For example, the electronic device (101) can transmit a signal on a first frequency band (331). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the first signal path (571) and the first antenna (591). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the first signal path (571) and the first antenna (591). Under the control of the processor (210) and / or the RF transceiver (220), the first pole (544a) and the first throw (549a) of the antenna switching circuit (540) can be electrically connected. Accordingly, the first signal path (571) for the first frequency band (331) can be electrically connected to the first antenna (591) via the first diplexer (561).

[0077] For example, the electronic device (101) can transmit a signal on a second frequency band (332). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the second signal path (572) and the first antenna (591). Under the control of the processor (210) and / or the RF transceiver (220), the second pole (544b) and the second throw (549b) of the antenna switching circuit (540) can be electrically connected. The second signal path (572) for the second frequency band (332) can be electrically connected to the first antenna (591) via the first diplexer (561).

[0078] For example, the electronic device (101) can transmit a signal on a third frequency band (333). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the third signal path (573) and the second antenna (592). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the third signal path (573) and the second antenna (592). Under the control of the processor (210) and / or the RF transceiver (220), the fourth pole (544d) and the fourth throw (549d) of the antenna switching circuit (540) can be electrically connected. Accordingly, the third signal path (573) for the third frequency band (333) can be electrically connected to the second antenna (592) via the second diplexer (562).

[0079] Although FIG. 5 illustrates one frequency band for a first frequency range (321), two frequency bands for a second frequency range (322), and one frequency band for a third frequency range (323), embodiments of the present disclosure are not limited thereto. An RFFE module (230) according to embodiments of the present disclosure may include components for a plurality of low frequency bands (e.g., a first power amplifier (511), or a first filter circuit (531)), components for a plurality of intermediate frequency bands (e.g., a second power amplifier (512), or a second filter circuit (532)), and components for a plurality of high frequency bands (e.g., a third power amplifier (513), or a third filter circuit (533)), and may include diplexers (e.g., a first diplexer (561), or a second diplexer (562)). Accordingly, the number of frequency bands corresponding to the frequency range exemplarily described in FIG. 5 is not to be construed as limiting the structure of the RFFE module (230) according to the embodiments. As a non-limiting example, supporting only one frequency band in a specific frequency range may also be understood as an embodiment of the present disclosure.

[0080] In FIG. 5, when explaining the role of the diplexer, in terms of the receiving path, it is described as separating signals received from the antenna into signals of a specific frequency range, extracting signals of a specific frequency range, or passing signals of a specific frequency range. However, these descriptions are not to be construed as limiting the implementation of the diplexer (e.g., a specific type of filter). For example, the diplexer may have a structure including one LPF and one BPF. By limiting the upper limit of the frequency to be passed, the diplexer can function stably. Through the LPF and BPF, signals input through the antenna can be divided into signals of different frequency ranges. As another example, the diplexer may include one LPF and one HPF. Through the LPF and HPF, signals input through the antenna can be divided into signals of different frequency ranges. As another example, the diplexer may include a BPF and another BPF. Through the BPF and the other BPF, signals input through the antenna can be extracted as signals of different frequency ranges.

Under the control of the processor (210) and / or the RF transceiver (220), the second pole (544b) and the third throw (549c) of the antenna switching circuit (540) may be electrically connected. The second signal path (572) for the second frequency band (332) may be electrically connected to the second antenna (892) via the second diplexer (562).

[0104] For example, the electronic device (101) may transmit a signal on a third frequency band (333). The electronic device (101) may control the antenna switching circuit (540) to electrically connect the third signal path (573) and the second antenna (892). Under the control of the processor (210) and / or the RF transceiver (220), the fourth pole (544d) and the fourth throw (549d) of the antenna switching circuit (540) may be electrically connected. The third signal path (573) for the third frequency band may be electrically connected to the second antenna (892) via the second diplexer (562).

[0105] Fig. 9 illustrates an example of an RFFE module (e.g., RFFE module (230)) including a diplexer. Fig. 9 illustrates an example in which the RFFE module (230) of Fig. 5 is connected to antennas other than the antennas of Fig. 5 (e.g., first antenna (591) and second antenna (592)). Like reference numerals may indicate like descriptions.

[0106] Referring to FIG. 9, the RFFE module (230) may include power amplifiers (510), transmit switches (520), filter circuits (530), antenna switching circuits (540), low-noise amplifiers (550), and / or receive switches (580). For a description of the components of the RFFE module (230), the description of FIG. 5 may be referenced. The RFFE module (230) may include an antenna switching circuit (540). The antenna switching circuit (540) may be connected to signal paths (570). The RFFE module (230) may include a first diplexer (561) and / or a second diplexer (562). The antenna switching circuit (540) may be connected to the first diplexer (561) and the second diplexer (562). The electronic device (101) may be configured to select an antenna corresponding to a signal path by controlling an electrical connection between a pole and a throw of the antenna switching circuit (540). For a description of the antenna switching circuit (540), the first diplexer (561), the second diplexer (562), and the signal paths (570), reference may be made to the description of FIG. 5.

[0107] In one embodiment, the RFFE module (230) may be connected to a first antenna (991) and a second antenna (992). For the first antenna (991) and the second antenna (992), reference may be made to the descriptions of the antenna (290) of FIG. 2. The first antenna (991) may be electrically connected to a first diplexer (561). For example, the RFFE module (230) may have a first diplexer port connected to the first diplexer (561). The first antenna (991) may be electrically connected to the first diplexer port. The second antenna (992) may be electrically connected to the second diplexer (562). For example, the RFFE module (230) may have a second diplexer port connected to the second diplexer (562). A second antenna (992) can be electrically connected to the second diplexer port.

[0108] According to one embodiment, one or more frequency bands that can be supported for each antenna may be defined. According to one embodiment, a first antenna (991) of an electronic device (101) may be configured to support frequency bands of a first frequency range (321) and a second frequency range (322). A second antenna (992) of an electronic device (101) may be configured to support frequency bands of a second frequency range (322) and a third frequency range (323). The first antenna (991) may be electrically connected to a first diplexer (561). One end of the first diplexer (561) may be electrically connected to a first throw (549a) of an antenna switching circuit (540). The other end of the first diplexer (561) may be electrically connected to a second throw (549b) of an antenna switching circuit (540). The second antenna (992) may be electrically connected to the second diplexer (562). One end of the second diplexer (562) may be electrically connected to the third throw (549c) of the antenna switching circuit (540). The other end of the second diplexer (562) may be electrically connected to the fourth throw (549d) of the antenna switching circuit (540).

[0109] The first diplexer (561) may be configured to pass signals in a frequency band of a first frequency range and signals in a frequency band of a second frequency range. For example, the first diplexer (561) may have a first port, a second port, and a third port. The first port of the first diplexer (561) may be connected to a first throw (549a), and the second port of the first diplexer (561) may be connected to a second throw (549b). The first diplexer (561) (e.g., a first filter of the first diplexer (561)) may be configured to extract (or separate) signals in a frequency band of the first frequency range from RF signals received through a first antenna (991) connected to the third port. The first diplexer (561) can provide the extracted signals to the first throw (549a) of the antenna switching circuit (540) through the first port of the first diplexer (561). The first diplexer (561) (e.g., the second filter of the first diplexer (561)) can be configured to extract (or separate) signals in a frequency band of the second frequency range from RF signals received through the first antenna (991) connected to the third port. The first diplexer (561) can provide the extracted signals to the second throw (549b) of the antenna switching circuit (540) through the second port of the first diplexer (561).

[0110] The second diplexer (562) may be configured to pass signals in a frequency band of a second frequency range and signals in a frequency band of a third frequency range. For example, the second diplexer (562) may have a first port, a second port, and a third port. The first port of the second diplexer (562) may be connected to a third throw (549c), and the second port of the second diplexer (562) may be connected to a fourth throw (549d). The second diplexer (562) (e.g., the third filter of the second diplexer (562)) may be configured to extract (or separate) signals in a frequency band of the second frequency range from RF signals received through a second antenna (992) connected to the third port. The second diplexer (562) can provide the extracted signals to the third throw (549c) of the antenna switching circuit (540) through the first port of the second diplexer (562). The second diplexer (562) (e.g., the fourth filter of the second diplexer (562)) can be configured to extract (or separate) signals in a frequency band of the third frequency range from RF signals received through the second antenna (992) connected to the third port. The second diplexer (562) can provide the extracted signals to the fourth throw (549d) of the antenna switching circuit (540) through the second port of the second diplexer (562).

[0111] For example, the electronic device (101) can transmit a signal on a first frequency band (331). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the first signal path (571) and the first antenna (991). Under the control of the processor (210) and / or the RF transceiver (220), the first pole (544a) and the first throw (549a) of the antenna switching circuit (540) can be electrically connected. Accordingly, the first signal path (571) for the first frequency band (331) can be electrically connected to the first antenna (991) via the first diplexer (561).

[0112] For example, the electronic device (101) can transmit a signal on a second frequency band (332). Since both the first antenna (991) and the second antenna (992) can support frequency bands in the second frequency range (322), the electronic device (101) can adaptively select an antenna for the second frequency band (332). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the second signal path (572) with the selected antenna (e.g., the first antenna (991) or the second antenna (992)). Under the control of the processor (210) and / or the RF transceiver (220), the second pole (544b) of the antenna switching circuit (540) can be selectively connected to one of the third throw (549c) and the fourth throw (549d). For example, when the first antenna (991) is selected, the second signal path (572) for the second frequency band (332) can be electrically connected to the first antenna (991) through the first diplexer (561). For example, when the second antenna (992) is selected, the second signal path (572) for the second frequency band (332) can be electrically connected to the second antenna (992) through the second diplexer (562).

[0113] For example, the electronic device (101) can transmit a signal on a third frequency band (333). The electronic device (101) can control the antenna switching circuit (540) to electrically connect the third signal path (573) and the second antenna (992). Under the control of the processor (210) and / or the RF transceiver (220), the fourth pole (544d) and the fourth throw (549d) of the antenna switching circuit (540) can be electrically connected. Accordingly, the third signal path (573) for the third frequency band can be electrically connected to the second antenna (992) via the second diplexer (562).

[0114] The electronic device (101) may select an antenna for transmitting or receiving a signal of the second frequency band (i.e., an intermediate frequency band) from among antennas (e.g., the first antenna (991) and the second antenna (992)) that support frequency bands of the second frequency range (322). The antenna may be selected according to various methods. According to one embodiment, the electronic device (101) may select an antenna based on signal quality. The signal quality may be, for example, at least one of reference signal received power (RSRP), reference signal received quality (RSRQ), received signal strength indicator (RSSI), signal to interference and noise ratio (SINR), carrier to interference and noise ratio (CINR), signal to noise ratio (SNR), error vector magnitude (EVM), bit error rate (BER), or block error rate (BLER). The electronic device (101) can measure the first signal quality of signals in the second frequency band (332) through the first antenna (991). The electronic device (101) can measure the second signal quality of signals in the second frequency band (332) through the second antenna (992). In one embodiment, the electronic device (101) can select an antenna by comparing the first signal quality and the second signal quality. For example, when the first signal quality is higher than the second signal quality, the electronic device (101) can select the first antenna (991). The electronic device (101) can control the antenna switching circuit (540) so that the second signal path (572) is electrically connected to the first diplexer (561).For example, if the first signal quality is lower than or equal to the second signal quality, the electronic device (101) may select the second antenna (992). The electronic device (101) may control the antenna switching circuit (540) so that the second signal path (572) is electrically connected to the second diplexer (562).

[0115] In one embodiment, the electronic device (101) may select an antenna based on a specified event. For example, if an event affecting the performance of the first antenna (991) is detected (e.g., USB insertion, camera activation, or user grip), the electronic device (101) may select the second antenna (992). The electronic device (101) may control the antenna switching circuit (540) such that the second signal path (572) is electrically connected to the second diplexer (562).

[0116] According to one embodiment, the electronic device (101) may select an antenna based on a state of the electronic device (101). For example, the electronic device (101) may be a foldable type device including two housing parts (e.g., a first housing part and a second housing part rotatable with respect to the first housing part). The performance of the antenna may vary depending on whether the state of the electronic device (101) is a folded state or an unfolded state. For example, when the electronic device (101) is in a folded state, the electronic device (101) may select the first antenna (991). For example, when the electronic device (101) is in an unfolded state, the electronic device (101) may select the second antenna (992). As another example, the electronic device (101) may be a rollable type device including two housing parts (e.g., a first housing part and a second housing part slidable with respect to the first housing part). Depending on whether the electronic device (101) is in a slide-in state (or a collapsed state, or a closed state) or a slide-out state (or an expanded state, or an open state), the performance of the antenna may vary. For example, when the electronic device (101) is in a slide-in state, the electronic device (101) may select the first antenna (991). For example, when the electronic device (101) is in a slide-out state, the electronic device (101) may select the second antenna (992).

[0117] As described with reference to FIGS. 5 to 9, the RFFE module (e.g., RFFE module (230)) according to embodiments of the present disclosure can be universally applied to electronic devices having different antenna arrangement structures. The RFFE module is implemented as a single chip, and the single chip can operate in various ways depending on its connection with antennas of the electronic device (e.g., electronic device (101)). Hereinafter, in the present disclosure, the RFFE module, in terms of being implemented as a chip, may be referred to as a wireless communication chip, an RF chip, a wireless transmission / reception chip, a wireless chip, a communication chip, and / or equivalent technical terms therefor. For example, if the RFFE module has a first antenna (e.g., first antenna (591)) that supports both a first frequency range and a second frequency range and a second antenna (e.g., second antenna (592)) that supports a third frequency range, the first diplexer port of the single chip may be connected to the first antenna, and the second antenna may be connected to the second diplexer port of the single chip. The single chip may support signal processing of all frequency bands of the first frequency range, the second frequency range, and the third frequency range. For example, if the RFFE module has a first antenna (e.g., the first antenna (691)) that the electronic device supports the first frequency range and a second antenna (e.g., the second antenna (692)) that supports the second frequency range and the third frequency range, the first diplexer port of the single chip may be connected to the first antenna, and the second antenna may be connected to the second diplexer port of the single chip. The single chip may support signal processing of all frequency bands of the first frequency range, the second frequency range, and the third frequency range. Additionally, as a non-limiting example, an antenna may be connected to an antenna port that is directly connected to an antenna switching module instead of the diplexer port to which the diplexer of the RFFE module is connected.Through this, the chip corresponding to the RFFE module according to the embodiments of the present disclosure can be universally used in electronic devices equipped with various antennas by having an additional diplexer port in addition to the antenna port.

[0118] Figures 10a to 10c illustrate examples of antenna switching circuits for carrier aggregation (CA).

[0119] Referring to FIG. 10A, the electronic device (101) may include a second filter circuit (532) for a second frequency band (332) and a fourth filter circuit (534) for a fourth frequency band (334). The electronic device (101) may include an antenna (1090). The antenna (1090) may support both the second frequency band (332) and the fourth frequency band (334). To connect the second filter circuit (532) and the fourth filter circuit (534) to the antenna switching circuit (540), a quadplexer in which the second filter circuit (532) and the fourth filter circuit (534) are implemented as one may be used.

[0120] Referring to FIG. 10B, the electronic device (101) may include a second filter circuit (532) for a second frequency band (332) and a fourth filter circuit (534) for a fourth frequency band (334). The electronic device (101) may include an antenna (1090). The antenna (1090) may support both the second frequency band (332) and the fourth frequency band (334). A switch (1070) may be used to connect the second filter circuit (532) to the antenna switching circuit (540). The switch (1070) may be connected to a port of the second filter circuit (532).

[0121] Referring to FIG. 10c, the electronic device (101) may include a second filter circuit (532) for a second frequency band (332) and a fourth filter circuit (534) for a fourth frequency band (334). The electronic device (101) may include a first antenna (1091) and a second antenna (1092).

[0122] As described in FIG. 10A or FIG. 10B, when using a quadplexer or a duplexer using a switch (1070), the electronic device (101) may be in a multi-loading state. Even if a signal is transmitted through one frequency band (e.g., the second frequency band (332)), insertion loss may increase due to components for other frequency bands (e.g., the fourth filter circuit (534) for the fourth frequency band (334)). When carrier aggregation (CA) is configured in the same frequency range (e.g., the second frequency range (322)), the electronic device (101) may control the antenna switching circuit (540) to independently connect an antenna to each filter circuit for the corresponding frequency band. For example, the electronic device (101) can control the antenna switching circuit (540) so that the first antenna (1091) is connected to the signal path for the second frequency band (332) and the second antenna (1091) is connected to the signal path for the fourth frequency band (334).

[0123] As mentioned through the embodiments described above, the RFFE module for all of the low band, the mid band, and the high band (e.g., the RFFE module (230)) may include diplexers. As the RFFE module for all of the low band, the mid band, and the high band is used, the LPF due to the arrangement of the separate diplexer may be omitted within the RFFE module. If the RFFE module supporting the low band and the mid band and the RFFE module supporting the high band are separately provided and the two RFFE modules are connected to one antenna through a diplexer, an LPF for mitigating or removing the harmonic components of the signals is required within each RFFE module. However, the LPF due to the external diplexer may be omitted through the RFFE module according to the embodiments of the present disclosure. In addition, since the diplexer is implemented within one RFFE module, an impedance matching circuit or separate wiring is not required for each of the input and output of the external diplexer, thereby improving space efficiency and reducing path loss. Through the RFFE module, in a limited space, Path loss can be reduced due to increased installation efficiency and reduced wiring, and RF transmission and reception performance can be improved.

[0124] The effects that can be obtained from the present disclosure are not limited to the effects mentioned above, and other effects that are not mentioned can be clearly understood by a person having ordinary skill in the art to which the present disclosure belongs from the description below.

The antenna switching circuit (540) may be configured to electrically connect one end of the first diplexer (561) with the first signal path, electrically connect the other end of the first diplexer (561) with the second signal path, and electrically connect the third signal path with one end of the second diplexer (562).

[0128] For example, the first diplexer (561) may be electrically connected to the first antenna. The second diplexer (562) may be electrically connected to the second antenna.

[0131] For example, the first diplexer (561) may be electrically connected to the first antenna. The second diplexer (562) may be electrically connected to the second antenna. The antenna switching circuit (540) may be configured to electrically connect the first signal path to one end of the first diplexer (561), selectively electrically connect the second signal path to the other end of the first diplexer (561) or the one end of the second diplexer (562), and electrically connect the third signal path to the other end of the second diplexer (562).

[0132] For example, the processor (210) may be configured to control the antenna switching circuit (540) to obtain a first signal quality in the second frequency band (332) through the first antenna via the RF transceiver (220), obtain a second signal quality in the second frequency band (332) through the second antenna, and selectively electrically connect the second signal path to one of the first diplexer (561) and the second diplexer (562) based on a comparison result of the first signal quality and the second signal quality.

[0133] For example, the RFFE module (230) may further include a fourth signal path connected to the second power amplifier (512) and including a fourth filter circuit (534) (534) for a fourth frequency band (334) in the second frequency range (322).

The plurality of conductive portions may include a first conductive portion used as a radiator of the first antenna and a second conductive portion used as a radiator of the second antenna.

[0137] For example, each of the first diplexer (561) and the second diplexer (562) can be used to attenuate harmonic frequency components.

[0138] For example, the RFFE module (230) may include a first low-noise amplifier electrically connected to the first filter circuit (531) for the first frequency band (331), a second low-noise amplifier electrically connected to the second filter circuit (532) for the second frequency band (332), and a third low-noise amplifier electrically connected to the third filter circuit (533) for the third frequency band (333).
