[0015] Portable devices (or user equipment) in a wireless environment can support dual connectivity, meaning they can connect to the network at multiple cell locations. Portable devices can support various frequency bands for dual connectivity to provide a robust wireless environment. For example, a portable device may include multiple front-end circuits (or front-end modules) to support various frequency bands. See below for reference. Figure 1 A more detailed description and explanation of portable devices including multiple front-end circuits.

[0016] Figure 1 An example of a portable device including multiple front-end circuits is shown.

[0017] Reference Figure 1 Portable devices (such as smartphones, tablets, laptops, smartwatches, etc.) may include multiple front-end circuits, including a first front-end circuit 101, a second front-end circuit 102, and a third front-end circuit 103. Portable devices may include circuitry with a power amplifier (PA) 121.

[0018] The first front-end circuit 101 may, for example, be used for signals received via antenna 191 within the downlink frequency range of a first frequency band. For example, the first front-end circuit 101 may include terminals connected to antenna 191. For example, the first front-end circuit 101 may include one or more low-noise amplifiers (LNAs) 181 configured to amplify signals within the downlink frequency range of the first frequency band. For example, the first front-end circuit 101 may include one or more filters 171 configured to pass signals within the downlink frequency range of the first frequency band. As a non-limiting example, portions of the one or more filters 171 may be included in duplexer 161, such as... Figure 1 As shown in the diagram. For example, the first front-end circuit 101 may include a switch 151 for selecting the receive path (or filter) to be connected to the antenna 191.

[0019] The second front-end circuit 102 may, for example, be used for signals received via antenna 192-1 in the downlink frequency range of a second frequency band. For example, the second front-end circuit 102 may include a terminal connected to antenna 192-1. For example, the second front-end circuit 102 may include one or more LNAs 182-1 configured to amplify signals in the downlink frequency range of the second frequency band. For example, the second front-end circuit 102 may include one or more filters 172-1 configured to pass signals in the downlink frequency range of the second frequency band. For example, the second front-end circuit 102 may include a switch 152 for selecting the receive path (or filter) to be connected to antenna 192-1.

[0020] The second front-end circuit 102 can, for example, be used for signals received via antenna 192-2 in the downlink frequency range of the third frequency band. For example, the second front-end circuit 102 may include a terminal connected to antenna 192-2. For example, the second front-end circuit 102 may include one or more LNAs 182-2 configured to amplify signals in the downlink frequency range of the third frequency band. For example, the second front-end circuit 102 may include one or more filters 172-2 configured to pass signals in the downlink frequency range of the third frequency band. For example, switch 152 can also be used to select the reception path to be connected to antenna 192-2.

[0021] The second front-end circuitry 102 may, for example, be used for signals transmitted via antenna 192-1 within the uplink frequency range of a second frequency band. For example, the second front-end circuitry 102 may include a power amplifier (PA) 122-1 configured to obtain the Tx power of the signal to be transmitted via antenna 192-1 within the uplink frequency range of the second frequency band. For example, the second front-end circuitry 102 may include one or more filters 132-1 for the signal to be transmitted via antenna 192-1 within the uplink frequency range of the second frequency band. At least portions of the paired one or more filters 132-1 and at least portions of one or more filters 172-1 may be implemented as duplexers. For example, the second front-end circuitry 102 may include a switch 142-1 for selecting a transmission path (or filter) for the signal to be transmitted via antenna 192-1 within the uplink frequency range of the second frequency band. For example, switch 152 may also be used to connect antenna 192-1 to the transmission path selected by switch 142-1.

[0022] The second front-end circuit 102 may, for example, be used for signals transmitted via antenna 192-2 within the uplink frequency range of the third frequency band. For example, the third front-end circuit 102 may include a power amplifier (PA) 122-2 configured to obtain the Tx power of the signal to be transmitted via antenna 192-2 within the uplink frequency range of the third frequency band. For example, the second front-end circuit 102 may include one or more filters 132-2 for signals to be transmitted via antenna 192-2 within the uplink frequency range of the third frequency band. At least portions of the paired one or more filters 132-2 and at least portions of one or more filters 172-2 may be implemented as duplexers. For example, the second front-end circuit 102 may include a switch 142-2 for selecting a transmission path (or filter) for the signal to be transmitted via antenna 192-2 within the uplink frequency range of the third frequency band. For example, switch 152 may also be used to connect antenna 192-2 to the transmission path selected by switch 142-2.

[0023] The third front-end circuit 103 may, for example, be used for signals received via antenna 193 in another downlink frequency range within the first frequency band. This other downlink frequency range in the first frequency band supported by the third front-end circuit 103 may be the same as, or at least partially different from, the downlink frequency range in the first frequency band supported by the first front-end circuit 101. For example, in this disclosure, the term "another (or other)" for "another downlink frequency range in the first frequency band" is used only to distinguish between the downlink frequency range in the first frequency band supported by the first front-end circuit 101 and the downlink frequency range in the first frequency band supported by the third front-end circuit 103. For example, the term "other" for "another downlink frequency range in the first frequency band" does not indicate a downlink frequency range in the first frequency band that does not overlap with the downlink frequency range in the first frequency band supported by the first front-end circuit 101. For example, the third front-end circuit 103 may include a terminal connected to antenna 193. For example, the third front-end circuitry 103 may include one or more LNAs 183 configured to amplify signals in other downlink frequency ranges within the third frequency band. For example, the third front-end circuitry 103 may include one or more filters 173 configured to pass signals in other downlink frequency ranges within the first frequency band. For example, the third front-end circuitry 103 may include a switch 153 for selecting the receive path connected to the antenna 193.

[0024] The third front-end circuit 103 may also be used, for example, for signals transmitted via antenna 193 within the uplink frequency range of the first frequency band. For example, the third front-end circuit 103 may include a PA 123 configured to obtain the Tx power of the signal to be transmitted via antenna 193 within the uplink frequency range of the first frequency band. For example, the third front-end circuit 103 may include one or more filters 133 for signals to be transmitted via antenna 193 within the uplink frequency range of the first frequency band. At least portions of the paired one or more filters 133 and at least portions of one or more filters 173 may be implemented as duplexers. For example, the third front-end circuit 103 may include a switch 143 for selecting a transmission path (or filter) for the signal to be transmitted via antenna 193 within the uplink frequency range of the first frequency band. For example, switch 153 may also be used to connect antenna 193 to the transmission path selected by switch 143.

[0025] For example, the portable device may also include PA 121 configured to obtain the Tx power of a signal in another uplink frequency range within the first frequency band. For example, the other uplink frequency range of the first frequency band may be the same as, or at least partially different from, the uplink frequency range of the first frequency band supported by the third front-end circuit 103, or may include within the uplink frequency range of the first frequency band supported by the third front-end circuit 103. For example, in this disclosure, the term "other" in "other uplink frequency range of the first frequency band" is used only to distinguish between the uplink frequency range of the first frequency band supported by the third front-end circuit 103 and the uplink frequency range of the first frequency band of the signal transmitted via PA 121. For example, the term "other" in "other uplink frequency range of the first frequency band" does not indicate an uplink frequency range of the first frequency band that does not overlap with the uplink frequency range of the first frequency band supported by the third front-end circuit 103. For example, PA 121 can be connected to the first front-end circuit 101 to transmit signals in other uplink frequency ranges within the first frequency band via antenna 191. For example, signals in other uplink frequency ranges within the first frequency band can use the first front-end circuit 101 as a transmission path. For example, unlike the second front-end circuit 102 and the third front-end circuit 103, the first front-end circuit 101 can be connected to PA 121 located outside the first front-end circuit 101. For example, signals in other uplink frequency ranges within the first frequency band can be transmitted using the Tx power obtained by PA 121 located outside the first front-end circuit 101 via antenna 191 connected to the first front-end circuit 101. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 193, signals in other uplink frequency ranges within the first frequency band can also be transmitted via antenna 191. For example, signals in the uplink frequency range of the first frequency band and signals in other uplink frequency ranges within the first frequency band can be transmitted via dual connection.

[0026] As a non-restrictive example, such as Figure 1 The arrangement of the first front-end circuit 101, the second front-end circuit 102, the third front-end circuit 103, and PA 121 shown can be adapted to support dual connections. However, to include additional components for higher quality services and / or new services, changes to the arrangement may be considered (or necessary).

[0027] For example, as Figure 1An alternative to the diagram could be a new front-end circuit integrating the first front-end circuit 101 and PA 121. However, since the new front-end circuit would not only require integration of the first front-end circuit 101 with PA 121, but also include an additional transmission controller (or transmission control circuitry) for PA 121 and an additional die (or semiconductor die) for PA 121, it may be unsuitable (or not recommended) in terms of installation space and / or cost.

[0028] As another example, Figure 1 An alternative to the diagram could be a new front-end circuit integrating the second front-end circuit 102 and the third front-end circuit 103. However, the new front-end circuit might require internal isolation to support dual connectivity solely through a combination of the first and second (or third) frequency bands. Furthermore, the temperature rise when using the new front-end circuit alone to support dual connectivity through a combination of the first and second (or third) frequency bands might be higher (or significantly higher) than when using the existing circuit. Figure 1 The second front-end circuit 102 and the third front-end circuit 103 support the increased temperature during dual-connection via a combination of the first and second (or third) frequency bands. Furthermore, the size of the new front-end circuit is larger (or much larger) than each of the second front-end circuit 102 and the third front-end circuit 103, which may be a disadvantage in terms of device flexibility. Moreover, since the new front-end circuit is an integrated circuit supporting the first, second, and third frequency bands, its yield can be lower (or much lower) than the yield of the first front-end circuit 101, the second front-end circuit 102, and the third front-end circuit 103.

[0029] refer to Figures 2 to 5 The electronic device shown and described (e.g., a portable device) may include a PA (e.g., corresponding to PA 121) connected within a second front-end circuit (e.g., corresponding to second front-end circuit 102) to a first front-end circuit (e.g., corresponding to first front-end circuit 101). Reference Figures 2 to 5 The electronic device shown and described can provide more spacious installation space by including a PA connected to the first front-end circuit within the second front-end circuit.

[0030] Figure 2 An example of an electronic device is shown, comprising a first front-end circuit and a second front-end circuit, wherein the second front-end circuit includes a power amplifier (PA) connected to the first front-end circuit.

[0031] Reference Figure 2The electronic device 200 can be a portable device, such as a smartphone, tablet computer, laptop computer, smartwatch, etc. However, the invention is not limited thereto. For example, the electronic device 200 can also be a fixed device (or a fixed device, or a non-movable device), such as a refrigerator, television (TV), Internet of Things (IoT) hub device, etc. The electronic device 200 may correspond to the following reference. Figure 7 At least a portion of the electronic device 701 is shown and described in more detail.

[0032] Electronic device 200 may include a first front-end circuit 201, a second front-end circuit 202, and a processor (e.g., including processing circuitry) 290.

[0033] The first front-end circuitry 201 (or the first front-end module (FEM) 201) can be used to receive a first signal 295-1 in the downlink frequency range of a first frequency band (e.g., less than 1 GHz) via antenna 291. For example, the first front-end circuitry 201 may include a terminal connected to antenna 291. For example, the first front-end circuitry 201 may include an LNA 281 configured to amplify the first signal 295-1 received via antenna 291. For example, LNA 281 may be configured to be connected to antenna 291 to amplify the first signal 295-1 received via antenna 291. For example, the LNA 281 connected to antenna 291 may indicate that LNA 281 is not only directly connected to antenna 291, but also that LNA 281 is connected to antenna 291 through one or more components. For example, although in Figure 2 Although not shown, the first front-end circuitry 201 may also include one or more components, such as filters (or duplexers) and / or switches on (or within) the receive path from antenna 291 to LNA 281. For example, the first signal 295-1 amplified by LNA 281 may be provided to processor 290 via a radio frequency integrated circuit (or radio frequency integrated circuit (RFIC)) (not shown).

[0034] As a non-limiting example, although the first front-end circuit 201 has a transmission path for a signal (e.g., the second signal 295-2) from PA 222-1 within the second front-end circuit 202 shown below ( Figure 2 The circuit may not be shown, but may include filters (or duplexers) and / or switches. However, unlike the second front-end circuit 202 (and / or the third front-end circuit 203), the first front-end circuit 201 may not include a PA for transmitting signals. For example, unlike the second front-end circuit 202 (and / or the third front-end circuit 203), the first front-end circuit 201 may not include any PA configured to obtain the Tx power of the signal.

[0035] The second front-end circuit 202 (or the second FEM 202) can be used to transmit a second signal 295-2 in the uplink frequency range of the first frequency band via antenna 291. For example, the second front-end circuit 202 may include a terminal connected (indirectly) to antenna 291 via the first front-end circuit 201. For example, the second front-end circuit 202 may include PA 222-1, which is configured to obtain the Tx power of the second signal 295-2 to be transmitted via antenna 291. For example, PA 222-1 may be configured to be connected to antenna 291, one of antennas 291 and 292. For example, PA 222-1 may be configured to be connected to antenna 291 via the first front-end circuit 201. For example, PA 222-1 may be disconnected from antenna 292. For example, the output terminal of PA 222-1 may be connected to a terminal (or input terminal) of the first front-end circuit 201. For example, PA 222-1 can be used to transmit a signal (e.g., a second signal 295-2) through another front-end circuit (e.g., a first front-end circuit 201) that is different from a front-end circuit (e.g., a second front-end circuit 202) that includes PA 222-1 (which is different from PA 222-2 shown below). As a non-limiting example, PA 222-1 can be used to transmit a signal (e.g., a second signal 295-2) in the uplink frequency range of a first frequency band that is not supported by one or more filters (and / or one or more duplexers) within the second front-end circuit 202, unlike PA 222-2 which is used to transmit a signal (e.g., a third signal 295-3) in the uplink frequency range of a second frequency band supported by one or more filters (and / or one or more duplexers) within the second front-end circuit 202. For example, the first front-end circuit 201 can be configured to transmit the second signal 295-2 with Tx power obtained using PA 222-1 within the second front-end circuit 202, which is configured to be connected to antenna 291.

[0036] The second front-end circuit 202 (or the second FEM 202) can also be used to transmit a third signal 295-3 in the uplink frequency range of a second frequency band (e.g., a band greater than 1 GHz) via antenna 292. For example, the second front-end circuit 202 may include a terminal (directly) connected to antenna 292. For example, the second front-end circuit 202 may include PA 222-2 configured to obtain the Tx power of the third signal 295-3 to be transmitted via antenna 292. For example, PA 222-2 may be configured to be connected to antenna 292 to obtain the Tx power of the third signal 295-3 to be transmitted via antenna 292. For example, PA 222-2 connected to antenna 292 may indicate that PA 222-2 is not only directly connected to antenna 292, but also indicates that PA 222-2 is connected to antenna 292 via one or more components. For example, although in Figure 2 Although not shown, the second front-end circuit 202 may also include one or more components, such as filters (or duplexers) and / or switches on (or within) the transmission path from PA 222-2 to antenna 292. For example, PA 222-2 may be disconnected from antenna 291. For example, the second front-end circuit 202 may be configured to transmit a third signal 295-3 through antenna 292. For example, the second front-end circuit 202 may be configured to provide the first front-end circuit 201 with the second signal 295-2 to be transmitted through antenna 291. For example, while transmitting the second signal 295-2 through antenna 291, the second front-end circuit 202 may be configured to transmit the third signal 295-3 through antenna 292. For example, while receiving the first signal 295-1 through antenna 291, the second front-end circuit 202 may be configured to transmit the third signal 295-3 through antenna 292.

[0037] As a non-limiting example, as described above, the second front-end circuit 202 may include […]. Figure 1 PA 121 corresponds to PA 222-1 and with Figure 1 PA 122-1 (and / or PA 122-2) corresponds to PA 222-2. For example, the second front-end circuit 202 may correspond to an integrated PA 222-2. Figure 1 PA 121 and Figure 1 The front-end circuit of the second front-end circuit 102. For example, integrating the second front-end circuit 102 with PA 121, just like the second front-end circuit 202, can be more efficient than the above-described alternatives (in... Figure 1 Description and Figure 2 The alternative described in the description is more efficient. For example, due to the second front-end circuit 102 (and... Figure 1 The first front-end circuit 101 is different) has a PA (e.g., Figure 1Therefore, integrating the second front-end circuit 102 with PA 121, just like the second front-end circuit 202, can be more efficient than the alternatives described above. For example, due to PA 222-1 (corresponding to PA 121) and PA 222-2 (corresponding to PA 122-1 and / or PA 122-2), the integration of the second front-end circuit 102 with PA 121, just like the second front-end circuit 202, can be more efficient than the alternatives described above. Figure 1 PA 122-1 and / or PA 122-2 can be included within a single die of the second front-end circuit 202, thus integrating the second front-end circuit 102 with PA 121, just like the second front-end circuit 202, can have a cost-effective advantage. For example, PA 222-1 (corresponding to PA 121) and PA 222-2 (corresponding to...) Figure 1 PA 122-1 and / or PA 122-2 may be included in a single die of the second front-end circuit 202, which may have a larger size than the second front-end circuit 102, but with flexibility in arrangement.

[0038] Processor 290 may include various processing circuits and is configured to control the first front-end circuit 201 and the second front-end circuit 202. For example, processor 290 may include... Figure 7 At least a portion of the processor 720, or may be compatible with Figure 7 At least a portion of the processor 720 corresponds to this. For example, processor 290 may include an application processor (AP) and / or a communication processor (CP). Processor 290 may include various processing circuitry and / or multiple processors. For example, as used herein (including the claims), the term "processor" may include various processing circuitry, including at least one processor, wherein one or more of the at least one processor may be configured individually and / or in a distributed manner to perform the various functions described herein. As used herein, when "processor," "at least one processor," and "one or more processors" are described as being configured to perform multiple functions, these terms cover, for example, but not limited to, a case where one processor performs some of the functions and another processor(s) performs other functions, and a case where a single processor can perform all of the functions. Furthermore, at least one processor may include, for example, a combination of processors performing the various functions described / disclosed in a distributed manner. At least one processor may execute program instructions to implement or perform various functions.

[0039] For example, processor 290 may be configured to control first front-end circuit 201 to receive a first signal 295-1 via antenna 291. For example, processor 290 may be configured to control first front-end circuit 201 and second front-end circuit 202 (or control second front-end circuit 202) to transmit a second signal 295-2 via antenna 291. For example, processor 290 may be configured to control PA 222-1 to obtain the Tx power of the second signal 295-2. For example, processor 290 may be configured to control first front-end circuit 201 (e.g., a duplexer (or filter) (not shown) and / or a switch (not shown) in first front-end circuit 201) to form a transmission path for the second signal 295-2 transmitted via antenna 291 within first front-end circuit 201. For example, processor 290 can control first front-end circuit 201 and second front-end circuit 202 (or control second front-end circuit 202) to transmit a third signal 295-3 via antenna 292 with Tx power obtained using PA 222-2, while transmitting a second signal 295-2 via antenna 291 with Tx power obtained using PA 222-1.

[0040] The electronic device 200 may also include a third front-end circuit 203.

[0041] The third front-end circuit 203 (or the third FEM 203) can also be used to transmit a fourth signal 295-4 in another uplink frequency range within the first frequency band via antenna 293. For example, the third front-end circuit 203 may include a terminal (directly) connected to antenna 293. For example, the third front-end circuit 203 may be disconnected from antennas 291 and 292. For example, the third front-end circuit 203 may include a PA 223 configured to obtain the Tx power of the fourth signal 295-4 to be transmitted via antenna 293. For example, PA 223 may be configured to be connected to antenna 293 to obtain the Tx power of the fourth signal 295-4 to be transmitted via antenna 293. For example, PA 223 connected to antenna 293 may indicate that PA 223 is not only directly connected to antenna 293, but also connected to antenna 293 via one or more components. For example, although in Figure 2Although not shown, the third front-end circuit 203 may include one or more components, such as filters (or duplexers) and / or switches, in the transmission path from PA 223 to antenna 293. For example, PA 223 may be disconnected from antennas 291 and 292. For example, the third front-end circuit 203 may be configured to transmit a fourth signal 295-4 through antenna 293. For example, while transmitting a second signal 295-2 through antenna 291, the third front-end circuit 203 may be configured to transmit a fourth signal 295-4 through antenna 293. For example, while transmitting a third signal 295-3 through antenna 292, the third front-end circuit 203 may be configured to transmit a fourth signal 295-4 through antenna 293. For example, while receiving a first signal 295-1 through antenna 291, the third front-end circuit 203 may be configured to transmit a fourth signal 295-4 through antenna 293.

[0042] For example, while transmitting the fourth signal 295-4 through antenna 293 with Tx power obtained using PA 223, processor 290 can control the first front-end circuit 201 and the second front-end circuit 202 (or control the second front-end circuit 202) to transmit the second signal 295-2 through antenna 291 with Tx power obtained using PA 222-1.

[0043] Optionally, the electronic device 200 may include a front-end circuit integrating the first front-end circuit 201 and the third front-end circuit 203 (or a single front-end circuit). For example, the front-end circuit may include a transmission path from PA 222-1 (located outside the front-end circuit) within the second front-end circuit 202 to the antenna 291, PA 223 (located inside the front-end circuit), and a transmission path from PA 223 to the antenna 293. For example, when the electronic device 200 includes the first front-end circuit 201 and the third front-end circuit 203, the processor 290 may control the front-end circuit integrating the first front-end circuit 201 and the third front-end circuit 203, as well as the second front-end circuit 202, to transmit a fourth signal 295-4 via the antenna 293 using the Tx power obtained from PA 223 within the front-end circuit, while simultaneously transmitting a second signal 295-2 via the antenna 291 using the Tx power obtained from PA 222-1 within the second front-end circuit 202.

[0045] Reference Figure 3The electronic device 300 can be a portable device, such as a smartphone, tablet computer, laptop computer, smartwatch, etc. However, the invention is not limited to this. For example, the electronic device 300 can also be a fixed device, such as a refrigerator, television, IoT hub device, etc. The electronic device 300 can correspond to... Figure 7 At least a portion of the electronic device 701 shown in the description.

[0046] Electronic device 300 may include a first front-end circuit 301, a second front-end circuit 302, a third front-end circuit 303, and a processor (e.g., including processing circuitry) 390. Processor 390 may be the same as or similar to processor 290 described above, and the above description of processor 290 also applies to processor 390.

[0047] The first front-end circuit 301 (or the first FEM 301) may include: an LNA 381 for receiving signals in or within a downlink frequency range of a first frequency band via an antenna 391; a filter 371 for transmitting signals in the downlink frequency range of the first frequency band; a filter 379 for transmitting signals in the uplink frequency range of the first frequency band; a switch 351; and a transmission path 388. For example, the filter 379 may be implemented as a duplexer 389 together with filter 371-1 in filter 371. For example, a PA 322-1 in the second front-end circuit 302 may be configured to be connected to the antenna 391 via the duplexer 389 and the switch 351. As a non-limiting example, any PA used to transmit signals through the antenna 391 may not be located on (or within) the transmission path 388.

[0048] For example, under the control of the processor 390, the first front-end circuit 301 can be configured to receive signals in the downlink frequency range of the first frequency band (e.g., corresponding to) via the antenna 391. Figure 2 The first signal 295-1). For example, processor 390 can control switch 351 to connect antenna 391 to one of filters 371 to receive signals in the downlink frequency range of the first frequency band through antenna 391. For example, processor 390 can control one of LNAs 381 to amplify the signal in the downlink frequency range of the first frequency band through antenna 391.

[0049] For example, the first front-end circuit 301 may be configured to transmit signals within the uplink frequency range of a first frequency band (e.g., corresponding to) via antenna 391, according to the control of processor 390. Figure 2The second signal 295-2). For example, processor 390 can control switch 351 to connect antenna 391 to filter 379 (or duplexer 389). For example, processor 390 can also control a second front-end circuit 302 (or second FEM 302) not directly connected (or indirectly connected) to antenna 391 to transmit signals in the uplink frequency range of the first frequency band through antenna 391. For example, processor 390 can control PA 322-1 within the second front-end circuit 302 (or second FEM 302) to obtain the Tx power of the signal to be transmitted through antenna 391 in the uplink frequency range of the first frequency band. For example, signals in the uplink frequency range of the first frequency band can be transmitted through transmission path 388 and antenna 391 using the Tx power obtained by PA 322-1.

[0050] The second front-end circuit 302 (or the second FEM 302) may include: an LNA 382-1 for receiving signals in (or within) a downlink frequency range in a second frequency band (e.g., a band from 1 GHz to 2.3 GHz) via antenna 392-1 (and / or antenna 392-2); a filter 372-1 for passing signals in the downlink frequency range of the second frequency band; an LNA 382-2 for receiving signals in (or within) a downlink frequency range in a third frequency band (e.g., a band from 2.3 GHz to 3.4 GHz) via antenna 392-2 (and / or antenna 392-1); a filter 372-2 for passing signals in the downlink frequency range of the third frequency band; and a PA 322-1 configured to obtain the Tx power of a signal to be transmitted via antenna 391 in the uplink frequency range of the first frequency band; PA PA 322-2 is configured to obtain the Tx power of a signal to be transmitted via antenna 392-1 (and / or antenna 392-2) in the uplink frequency range of a second frequency band; PA 322-3 is configured to obtain the Tx power of a signal to be transmitted via antenna 392-2 (and / or antenna 392-1) in the uplink frequency range of a third frequency band; filter 332-1 is used to pass the signal in the uplink frequency range of the second frequency band; filter 332-2 is used to pass the signal in the uplink frequency range of the third frequency band; switch 342-1 is used to connect one of the filters 332-1 to PA 322-2; and switch 342-2 is used to connect one of the filters 332-2 to PA 322-3. As a non-limiting example, one of the filters 332-1 and one of the filters 372-1 may be implemented as a duplexer. For example, the second front-end circuit 302 may include a duplexer 387. As a non-limiting example, one of the filters 332-2 and one of the filters 372-2 may be implemented as a duplexer. For example, the second front-end circuit 302 may include a duplexer 386. For example, the second front-end circuit 302 may include a switch 352 for connecting antenna 392-1 to one of the duplexers 387 and antenna 392-2 to one of the duplexers 386.

[0051] For example, unlike PA 322-2 and PA 322-3, PA 322-1 can be disconnected from the component for transmitting signals within the second front-end circuitry 302 via antennas 392-1 and 392-2. For example, PA 322-1 can be configured to be disconnected from antennas 392-1 and 392-2 and connected to antenna 391 via the first front-end circuitry 301.

[0052] For example, the second front-end circuit 302 can be configured to obtain the Tx power of a signal to be transmitted via antenna 391 in the uplink frequency range of the first frequency band, according to the control of processor 390. For example, a signal in the uplink frequency range of the first frequency band can be transmitted via the first front-end circuit 301 and antenna 391 using the Tx power obtained by PA 322-1.

[0053] For example, the second front-end circuit 302 can be configured to transmit a signal within the uplink frequency range of the second frequency band via antenna 392-1, under the control of processor 390. For example, while transmitting a signal within the uplink frequency range of the first frequency band via antenna 391, processor 390 can control PA 322-2 to obtain the Tx power of the signal to be transmitted via antenna 392-1 within the uplink frequency range of the second frequency band. For example, while transmitting a signal within the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switches 342-1 and 352 to transmit the signal within the uplink frequency range of the second frequency band via antenna 392-1.

[0054] For example, the second front-end circuit 302 can be configured to transmit a signal in the uplink frequency range of the third frequency band via antenna 392-2, under the control of processor 390. For example, while transmitting a signal in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control PA 322-3 to obtain the Tx power of the signal to be transmitted via antenna 392-2 in the uplink frequency range of the third frequency band. For example, while transmitting a signal in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switches 342-2 and 352 to transmit a signal in the uplink frequency range of the third frequency band via antenna 392-2.

[0055] For example, the second front-end circuit 302 can be configured to receive signals in the downlink frequency range of the second frequency band via antenna 392-1, under the control of processor 390. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switch 352 to receive signals in the downlink frequency range of the second frequency band via antenna 392-1. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control one of LNAs 382-1 to amplify the signals received via antenna 392-1 in the downlink frequency range of the second frequency band.

[0056] For example, the second front-end circuit 302 can be configured to receive signals in the downlink frequency range of the third frequency band via antenna 392-2, under the control of processor 390. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switch 352 to receive signals in the downlink frequency range of the third frequency band via antenna 392-2. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control one of LNAs 382-2 to amplify the signals received via antenna 392-2 in the downlink frequency range of the third frequency band.

[0057] The third front-end circuit 303 (or the third FEM 303) may include: an LNA 383 for receiving signals in (or within) another downlink frequency range in the first frequency band via antenna 393; a filter 373 for passing signals in another downlink frequency range in the first frequency band; a PA 323 configured to obtain the Tx power of a signal to be transmitted via antenna 393 in (or within) another uplink frequency range in the first frequency band; a filter 333 for passing signals in another uplink frequency range in the first frequency band; and a switch 343 for connecting PA 323 to one of the filters 333. As a non-limiting example, one of the filters 333 and one of the filters 373 may be implemented as a duplexer. For example, the third front-end circuit 303 may include a duplexer 385. For example, the third front-end circuit 303 may include a switch 353 for connecting antenna 393 to one of the duplexers 385.

[0058] For example, the third front-end circuit 303 can be configured to transmit signals in other uplink frequency ranges within the first frequency band via antenna 393, under the control of processor 390. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control PA 323 to obtain the Tx power of the signals to be transmitted via antenna 393 in other uplink frequency ranges within the first frequency band. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switches 343 and 353 to transmit signals in other uplink frequency ranges within the first frequency band via antenna 393.

[0059] For example, the third front-end circuit 303 can be configured to receive signals in another downlink frequency range within the first frequency band via antenna 393, under the control of processor 390. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control switch 353 to receive signals in other downlink frequency ranges within the first frequency band via antenna 393. For example, while transmitting signals in the uplink frequency range of the first frequency band via antenna 391, processor 390 can control one of LNAs 383 to amplify signals received via antenna 393 in other downlink frequency ranges within the first frequency band.

[0060] Despite Figure 3 Not shown, but electronic device 300 may also include front-end circuitry (or front-end modules) comprising terminals (directly) connected to other antennas, distinct from antennas 391, 392-1, 392-2, and 393, respectively, to receive signals in another downlink frequency range of the second frequency band, transmit signals in another uplink frequency range of the second frequency band, receive signals in another downlink frequency range of the third frequency band, and transmit signals in another uplink frequency range of the third frequency band. For example, the other antennas associated with the front-end circuitry may be spaced apart from antennas 392-1 and 392-2. For example, unlike the second front-end circuitry 302, the front-end circuitry may not include a PA (such as PA 322-1) connected to another front-end circuitry.

[0061] PA (such as) Figure 2 PA 222-1 and Figure 3 PA 322-1 can be arranged within an electronic device (e.g., a portable device) along with components for antenna switching diversity (e.g., switches). These components are... Figure 4 and Figure 5 As shown in the description.

[0062] Figure 4 An example of an electronic device is shown, comprising a first front-end circuit and a second front-end circuit, wherein the second front-end circuit includes a PA that can be connected to the first front-end circuit.

[0063] Reference Figure 4 The electronic device 400 can be a portable device, such as a smartphone, tablet computer, laptop computer, smartwatch, etc. However, the invention is not limited thereto. For example, the electronic device 400 can be a fixed device, such as a refrigerator, TV, or IoT hub device. The electronic device 400 can be connected to... Figure 7 The description of the electronic device 701 at least partially corresponds to that of the device shown.

[0064] Electronic device 400 may include a first front-end circuit 401, a second front-end circuit 402, and a processor (e.g., including processing circuitry) 490. Processor 490 may be the same as or similar to processor 290 described above, and the above description of processor 290 also applies to processor 490.

[0065] The first front-end circuit 401 (or the first FEM 401) may include an LNA 481 (e.g., corresponding to) for receiving via antenna 491 a first signal 495-1 in the downlink frequency range of the first frequency band. Figure 2 The LNA 281 and a transmission path (not shown) for a second signal 495-2 transmitted via antenna 491 in the uplink frequency range of the first frequency band. For example, this transmission path can be configured to connect to switch 452 for connection with PA 422-1.

[0066] The second front-end circuit 402 (or the second FEM 402) may include: PA 422-1, for obtaining the Tx power of the second signal 495-2 transmitted through antenna 492-1; PA 422-2 (e.g., corresponding to...) Figure 2 PA 222), for obtaining the Tx power of the third signal 495-3 transmitted via antenna 492-2 in the uplink frequency range of the second frequency band; and switch 452, for selecting the antenna to be connected to PA 422-1 from antenna 491 and antenna 492-1.

[0067] Processor 490 can control first front-end circuitry 401 to receive first signal 495-1. For example, processor 490 can control LNA 481 to amplify the first signal 495-1 received through antenna 491.

[0068] Processor 490 can control second front-end circuitry 402 to transmit a second signal 495-2. For example, processor 490 can control PA 422-1 to obtain or generate the Tx power of the second signal 495-2 to be transmitted via antenna 491 or antenna 492-1. For example, processor 490 can control switch 452 to connect PA 422-1 to antenna 491 among antennas 491 and 492-1, so that the second signal 495-2 can be transmitted via antenna 491 using the Tx power obtained by PA 422-1. For example, processor 490 can control switch 452 to connect PA 422-1 to antenna 492-1 among antennas 491 and 492-1, so that the second signal 495-2 can be transmitted via antenna 492-1 using the Tx power obtained by PA 422-1. As a non-limiting example, the second signal 495-2 can be transmitted via antenna 492-1 while receiving the first signal 495-1 via antenna 491.

[0069] Processor 490 can control second front-end circuitry 402 to transmit a third signal 495-3. For example, processor 490 can control PA 422-2 to obtain or generate the Tx power of the third signal 495-3 to be transmitted through antenna 492-2. For example, the third signal 495-3 can be transmitted through antenna 492-2 simultaneously with the transmission of the second signal 495-2 through antenna 491. For example, the third signal 495-3 can be transmitted through antenna 492-2 simultaneously with the transmission of the second signal 495-2 through antenna 492-1.

[0070] As a non-limiting example, while transmitting the second signal 495-2 via antenna 492-1, processor 490 can obtain information about the communication quality (or the state of the second signal 495-2) related to the second signal 495-2. For example, processor 490 can use this information to control switch 452 to change the antenna connected to PA 422-1 from antenna 492-1 to antenna 491.

[0071] As a non-limiting example, while transmitting the second signal 495-2 via antenna 491, processor 490 can obtain communication quality information (or the state of the second signal 495-2) related to the second signal 495-2. For example, based on this information, processor 490 can control switch 452 to change the antenna connected to PA 422-1 from antenna 491 to antenna 492-1.

[0072] The electronic device 400 may also include a third front-end circuit 403 (or a third FEM 403).

[0073] The third front-end circuit 403 may include PA 423 to obtain or generate the Tx power of a fourth signal 495-4 to be transmitted via antenna 493 in another uplink frequency range of the first frequency band.

[0074] Processor 490 can control third front-end circuitry 403 to transmit a fourth signal 495-4. For example, processor 490 can control PA 423 to obtain or generate the Tx power of the fourth signal 495-4 to be transmitted through antenna 493. For example, the fourth signal 495-4 can be transmitted through antenna 493 simultaneously with the transmission of the second signal 495-2 through antenna 491. For example, the fourth signal 495-4 can be transmitted through antenna 493 simultaneously with the transmission of the second signal 495-2 through antenna 492-1.

[0075] As a non-limiting example, while transmitting the fourth signal 495-4, the processor 490 can obtain communication quality information (or the state of the second signal 495-2) related to the second signal 495-2 transmitted through the antenna 492-1. For example, the processor 490 can control the switch 452 based on this information to change the antenna connected to PA 422-1 from antenna 492-1 to antenna 491.

[0076] As a non-limiting example, processor 490 can obtain communication quality information (or the state of the second signal 495-2) related to the second signal 495-2 transmitted through antenna 491, while simultaneously transmitting a fourth signal 495-4. For example, processor 490 can control switch 452 based on this information to change the antenna connected to PA 422-1 from antenna 491 to antenna 492-1.

[0077] Figure 5 An example of an electronic device is shown, comprising a first front-end circuit, a second front-end circuit including a PA that can be connected to the first front-end circuit, and a third front-end circuit.

[0078] Reference Figure 5 Electronic device 500 can be a portable device, such as a smartphone, tablet computer, laptop computer, smartwatch, etc. However, the invention is not limited thereto. For example, electronic device 500 can be a fixed device (or a fixed device, or a non-movable device), such as a refrigerator, TV, or IoT hub device. Electronic device 500 can correspond to Figure 7 At least a portion of the electronic device 701 shown in the description.

[0079] Electronic device 500 may include a first front-end circuit 301, a second front-end circuit 502, and a processor 590 (e.g., including processing circuitry). Processor 590 may be the same as or similar to processor 290 described above, and the above description of processor 290 also applies to processor 590.

[0080] The first front-end circuit 301 can correspond to Figure 3 The first front-end circuit 301 is shown in the description.

[0081] The second front-end circuit 502 can be a front-end circuit in which additional components for antenna switching diversity are added. Figure 3 The second front-end circuit 302 is shown in the description. For example, the second front-end circuit 502 may also include a switch 583 connected to PA 322-1, filter 532-3, filter 572-3, LNA 582-3 and antenna 592-3.

[0082] For example, PA 322-1 within the second front-end circuit 502 can be configured to be connected to antenna 391 via switch 583. For example, PA 322-1 within the second front-end circuit 502 can be configured to be connected to antenna 592-3 via switch 583.

[0083] For example, filters 532-3 and 572-3 within the second front-end circuit 502 can be implemented as a duplexer 584.

[0084] For example, processor 590 can control LNA 582-3 to amplify signals received through antenna 592-3 and duplexer 584 (or filter 572-3).

[0085] For example, processor 590 can control PA 322-1 to obtain the Tx power of a signal within the uplink frequency range of a first frequency band. For example, processor 590 can control switch 583 to connect duplexer 389 to PA 322-1, so that a signal within the uplink frequency range of the first frequency band can be transmitted via antenna 391 using the Tx power obtained from PA 322-1. For example, processor 590 can control switch 583 to connect duplexer 584 to PA 322-1, so that a signal within the uplink frequency range of the first frequency band can be transmitted via antenna 592-3 using the Tx power obtained from PA 322-1. For example, antenna switching diversity performed by controlling switch 583 can be used in dual connectivity.

[0086] As a non-limiting example, component 581, including switch 583 and duplexer 584, can be replaced by other components. See below for reference. Figure 6 Examples of other components are explained and described in more detail.

[0087] Figure 6 The replacement is shown Figure 5 Another example of a switch in the diagram.

[0088] Reference Figure 6The second front-end circuitry 602 may include a filter 532-3 directly connected to PA 322-1 and a switch 601 for connecting one of antennas 391 and 592-3 to the filter 532-3. For example, unlike switch 583, switch 601 may be located between filter 532-3 and the antennas (e.g., antennas 391 and 592-3). For example, switch 601 may be configured to connect antenna 391 to filter 532-3 to connect PA 322-1 to antenna 391. For example, switch 601 may be configured to connect antenna 592-3 to filter 532-3 to connect PA 322-1 to antenna 592-3. For example, switch 601 may operate according to the control of processor 590.

According to embodiments, communication module 790 may include wireless communication module 792 (e.g., cellular communication module, short-range wireless communication module, or Global Navigation Satellite System (GNSS) communication module) or wired communication module 794 (e.g., local area network (LAN) communication module or power line communication (PLC) module). A corresponding one of these communication modules can communicate via a first network 798 (e.g., a short-range communication network, such as Bluetooth). TM The communication module 792 can communicate with external electronic devices via a Wi-Fi Direct or Infrared Data Association (IrDA) network or a second network 799 (e.g., a long-range communication network, such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or a wide area network (WAN))). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components that are separate from each other (e.g., multiple chips). The wireless communication module 792 can use user information (e.g., International Mobile Subscriber Identity (IMSI)) stored in the user identification module 796 to identify and authenticate electronic devices 701 in the communication network (e.g., a first network 798 or a second network 799).

[0107] Wireless communication module 792 can support 5G networks following 4G networks and next-generation communication technologies, such as new radio (NR) access technologies.

The third front-end circuit may include a PA (e.g., PA 223) configured to be connected to the third antenna. The electronic device may include: at least one processor including processing circuitry; and a memory configured to store instructions. When executed individually and / or jointly by at least one processor, the instructions enable the electronic device to: simultaneously transmit a first signal in a first uplink frequency range of a first frequency band via a third antenna using a PA in a third front-end circuit to obtain a Tx power of a second signal transmitted via the first antenna in a second uplink frequency range of the first frequency band; and simultaneously transmit the first signal via the third antenna using a PA in a third front-end circuit to obtain a Tx power of a third signal transmitted via a second antenna in an uplink frequency range of the second frequency band.

[0123] For example, when executed individually and / or jointly by at least one processor, the instructions may enable an electronic device to: transmit a third signal using the Tx power obtained by the second PA in the second front-end circuit via a second antenna connected to the second front-end circuit, while simultaneously controlling the first PA in the second front-end circuit to obtain the Tx power of the second signal transmitted via the first antenna.

The at least one processor may be configured individually and / or collectively to: transmit a second signal via a third antenna using the Tx power obtained by the second PA in the second front-end circuit, while simultaneously controlling a switch to connect a first PA in the second front-end circuit to the first antenna among the first antenna and the second antenna, so as to transmit the first signal via the first antenna among the first antenna and the second antenna using the Tx power obtained by the first PA in the second front-end circuit; or to control a switch to connect a first PA in the second front-end circuit to the second antenna among the first antenna and the second antenna, so as to transmit the first signal via the second antenna among the first antenna and the second antenna using the Tx power obtained by the first PA in the second front-end circuit.

[0128] For example, at least one processor may be configured individually and / or collectively to identify the state of the transmitted first signal while transmitting the second signal, and based on that state, to control a switch to change the antenna of the first PA connected in the second front-end circuit from the second antenna to the first antenna.
