Description

Technical Field

[0001] This application relates to communication technology, and more particularly to a wireless communication device, method and apparatus. Background Technology

[0002] Currently, based on the Wireless Fidelity (Wi-Fi) / BT coexistence architecture, an additional BT antenna is added, along with a matching front-end RF path. The receiving path is completely independent, while the transmitting path is switched with the original normal path via a switch. When it is necessary to ensure that Wi-Fi and BT work simultaneously in heavy-load scenarios, the BT path is switched to a third path to achieve independent path operation.

[0003] However, the addition of an extra BT antenna, which requires a certain level of isolation (20-30dB or more) between the BT antenna and the existing Wi-Fi antenna, increases costs and reduces signal transmission efficiency. Summary of the Invention

[0042] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies or terms of the embodiments of this application are described below. The following related technologies or related terms are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and all of them fall within the protection scope of the embodiments of this application.

[0043] Wi-Fi and BitTorrent (BT) are two of the most important technologies in the wireless field. They are mainly used for user activities in areas such as home life. For example, Wi-Fi networks are used in homes to provide data services for various terminals. BT is mainly used for connection technology in interconnected devices or other related products, such as the application of key products like headphones and car keys.

[0044] The Wi-Fi front-end module (FEM) is an important component in the Wi-Fi field. As the name suggests, the Wi-Fi FEM is an integrated front-end module for Wi-Fi. It is an important component in the entire Wi-Fi radio frequency link, including the transmission and reception paths, and can also support BT (BitTorrent) functionality.

[0045] Figure 1 The diagram shows a classic Wireless Fidelity (Wi-Fi) / Bluetooth (BT) architecture. Only 2.4G Wi-Fi is shown. The wireless transceiver supports Wi-Fi / BT signal transmission and reception, and the Wi-Fi and BT reception signals share a common channel, while the transmission uses two separate channels. However, the front-end FEM switch is shared, so it also adopts a common channel design in hardware. But for existing users, there is a typical scenario where Bluetooth and Wi-Fi need to coexist, which is a typical scenario we often encounter (Bluetooth headset and Wi-Fi data), such as playing games on Wi-Fi while wearing Bluetooth headsets.

[0046] like Figure 2 The diagram shows a classic Wi-Fi / BT coexistence architecture. Its core idea is to add an extra BT antenna and a matching front-end RF path. The receiving path is completely independent, while the transmitting path is switched with the original normal path via a switch. When Wi-Fi and BT need to work simultaneously under heavy load, the BT path is switched to a third path to achieve independent operation.

[0047] like Figure 3 The diagram shown is a typical 2.4G Wi-Fi FEM block diagram, which mainly has 5 signal ports: TX / RX / BT / CPL and antenna port ANT. The TX port is for Wi-Fi transmission, the BT port only supports Bluetooth transmission, the RX port supports Wi-Fi / BT reception, and the CPL is mainly the output of the transmission coupler.

[0048] Transmit (TX): Contains a Wi-Fi-enabled PA, and the PA's output includes SAW.

[0049] BT: There is an internal switch to switch between PA mode and Bypass mode. Because BT has lower power, its PA gain is lower than that of WIFI, and its power consumption is also lower.

[0050] Receive (RX): Internally includes SAW and LNA, and also supports bypass path.

[0051] The embodiments in this application are for solving... Figure 2 To address the issues of increased cost and reduced signal transmission efficiency in the technical solutions presented, a wireless communication device is proposed.

[0052] Figure 4 Schematic diagram of the structure of the wireless communication device provided in the embodiments of this application Figure 1 ,like Figure 4 As shown, the wireless communication device 400 is applied to a communication device. The wireless communication device 400 includes: a wireless transceiver 401, a Wi-Fi transmitting front-end module 402, a first power divider 403, a Bluetooth transmitting front-end module 404, a first switch 405, and an antenna 406. The Bluetooth transmitting front-end module 404 includes a first power amplifier 4041. The wireless transceiver 401 is connected to the Wi-Fi transmitting front-end module 402 through a Wi-Fi transmitting TX port. The Wi-Fi transmitting front-end module 402 is connected to the first power divider 403. The wireless transceiver 401 is connected to the first power amplifier 4041 through a Bluetooth transmitting TX port. The first power amplifier 4041 is connected to the first power divider 403. The first power divider 403 is connected to the first switch 405. The first switch 405 is connected to the antenna.

[0053] The wireless transceiver 401 is used to control the first switch 405 to connect the wireless transceiver 401, the Wi-Fi transmitting front-end module 402, the first power divider 403 and the antenna 406, and to control the first switch 405 to connect the wireless transceiver 401, the first power amplifier 4041, the first power divider 403 and the antenna 405.

[0054] The Wi-Fi transmitting front-end module 402 is used to process the first Wi-Fi signal transmitted by the wireless transceiver 401 to obtain the processed first Wi-Fi signal;

[0055] The first power amplifier 4041 is used to process the first Bluetooth signal transmitted by the wireless transceiver 401 to obtain the processed first Bluetooth signal.

[0056] The first power divider 403 is used to aggregate the processed first Wi-Fi signal and the processed first Bluetooth signal to obtain an aggregated signal, and output the aggregated signal to the antenna 406.

[0057] In this embodiment, when the communication device detects that the Wi-Fi module and Bluetooth module are working simultaneously, it informs the wireless transceiver. Further, in a scenario where the wireless transceiver simultaneously transmits Wi-Fi and Bluetooth signals, it controls a first switch to connect the wireless transceiver, the Wi-Fi front-end module, the first power divider, and the antenna; and controls the first switch to connect the wireless transceiver, the first power amplifier 4041, the first power divider, and the antenna. This allows the first Wi-Fi signal transmitted by the wireless transceiver to be processed by the Wi-Fi front-end module and then transmitted to the first power divider, and the first Bluetooth signal transmitted by the wireless transceiver to be processed by the first power amplifier and then transmitted to the first power divider. The first power divider then aggregates the processed first Wi-Fi signal and the first Bluetooth signal and outputs them to the antenna.

[0058] In this embodiment, a first power divider with signal aggregation function is provided at the output end of the Wi-Fi transmitting front-end module and the output end of the first power amplifier included in the Bluetooth transmitting front-end module. The first power divider can aggregate the processed first Wi-Fi signal output by the Wi-Fi transmitting front-end module and the processed first Bluetooth signal output by the first power amplifier at the same time and transmit them to the antenna through the antenna port; thus, compared to Figure 2 The proposed solution eliminates the need for an additional Bluetooth antenna, thus avoiding crosstalk between Wi-Fi and Bluetooth signals via antenna radiation. This reduces costs while improving signal transmission efficiency. In other words, it enables simultaneous transmission of Wi-Fi and Bluetooth signals using existing antenna components.

[0059] In some embodiments of this application, the wireless communication device further includes a second switch 407;

[0060] like Figure 5 As shown, the Wi-Fi transmitting front-end module 402 is connected to the second switch 407, and the second switch 407 is connected to the first power divider 403 and the first switch 405 respectively.

[0061] The wireless transceiver 401 is also used to control the first switch 405 and the second switch 407 to connect the wireless transceiver 401, the Wi-Fi transmitting front-end module 402 and the antenna 406.

[0062] The Wi-Fi transmitting front-end module 402 is also used to process the second Wi-Fi signal transmitted by the wireless transceiver 401, obtain the processed second Wi-Fi signal, and output the processed second Wi-Fi signal to the antenna 406.

[0063] In this embodiment, when the communication device detects that the Wi-Fi module is operating independently, it informs the wireless transceiver. Furthermore, in a scenario where the wireless transceiver is transmitting a Wi-Fi signal independently, it controls a first switch and a second switch to connect the wireless transceiver, the Wi-Fi front-end module, and the antenna, so that the second Wi-Fi signal transmitted by the wireless transceiver is processed by the Wi-Fi front-end module and then output to the antenna.

[0064] In this embodiment, by setting a second switch between the output of the Wi-Fi transmitting front-end module and the input of the first power divider and the first switch, when transmitting a Wi-Fi signal alone, the first switch and the second switch are controlled to connect the wireless transceiver, the Wi-Fi transmitting front-end module and the antenna. In this way, the output signal of the Wi-Fi transmitting front-end module can be directly transmitted to the antenna without passing through the first power divider, ensuring that the output signal is not lost.

[0065] The second switch can be a single-pole double-throw (SPDT) switch.

[0066] Furthermore, in some embodiments, the wireless transceiver is used to: in scenarios where Wi-Fi signals and Bluetooth signals are transmitted simultaneously, control a first switch and a second switch to connect the wireless transceiver, the Wi-Fi transmitting front-end module, the first power divider, and the antenna; and control the first switch to connect the wireless transceiver, the first power amplifier, the first power divider, and the antenna, so that the first Wi-Fi signal transmitted by the wireless transceiver is processed by the Wi-Fi transmitting front-end module and transmitted to the first power divider, and the first Bluetooth signal transmitted by the wireless transceiver is processed by the first power amplifier and transmitted to the first power divider, and then the first power divider aggregates the processed first Wi-Fi signal and the first Bluetooth signal and outputs them to the antenna.

[0067] In this embodiment of the application, the Wi-Fi transmitting front-end module includes: a second power amplifier (i.e., PA Wi-Fi) and a second filter (e.g., SAW1), wherein the wireless transceiver is connected to PA Wi-Fi through a Wi-Fi transmitting port, PA Wi-Fi is connected to SAW1, SAW1 is connected to a first power divider, and the first power divider is connected to an antenna through a first switch.

[0068] In some embodiments of this application, the Bluetooth transmitting front-end module 404 further includes a third switch 408, and the wireless communication device further includes a fourth switch 409;

[0069] like Figure 6As shown, the wireless transceiver 401 is connected to the first power amplifier 4041 and the first switch 405 respectively via the third switch 408. The first power amplifier 4041 is connected to the fourth switch 409. The fourth switch 409 is connected to the first power divider 403 and the first switch 405 respectively.

[0070] The wireless transceiver 401 is also used to control the third switch 408, the fourth switch 409 and the first switch 405 to conduct the connection between the wireless transceiver 401, the first power amplifier 4041 and the antenna 406.

[0071] The first power amplifier 4041 is also used to process the second Bluetooth signal to obtain the processed second Bluetooth signal, and output the processed second Bluetooth signal to the antenna 406.

[0072] In this embodiment, when the communication device detects that the Bluetooth module is working independently, it informs the wireless transceiver. Furthermore, when the wireless transceiver is transmitting a Bluetooth signal independently, and the second Bluetooth signal transmitted by the wireless transceiver meets the weak signal condition, it controls the third switch, the fourth switch, and the first switch to connect the wireless transceiver, the first power amplifier, and the antenna, so that the second Bluetooth signal is processed by the first power amplifier and then output to the antenna.

[0073] In this embodiment, by setting a fourth switch between the output terminal of the first power amplifier and the input terminal of the first power divider and the first switch, when transmitting a Bluetooth signal alone, the third switch, the fourth switch and the first switch are controlled to connect the wireless transceiver, the first power amplifier and the antenna. In this way, the output signal of the first power amplifier can be directly transmitted to the antenna without passing through the first power divider, ensuring that the output signal is not lost.

[0074] In some embodiments, the weak signal condition includes: a first quality parameter of the signal is less than or equal to a first threshold; wherein the first quality parameter is positively correlated with the signal quality;

[0075] For example, the first quality parameter may include, but is not limited to, at least one of the following: Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Signal-to-Noise Ratio (SNR), etc.

[0076] Alternatively, the second quality parameter of the signal is greater than or equal to the second threshold; wherein the second quality parameter is negatively correlated with the signal quality.

[0077] For example, the second quality parameter may include, but is not limited to, the Adjacent Channel Leakage Ratio (ACLR).

[0078] Furthermore, in some embodiments, the wireless transceiver is used to control a first switch to connect the wireless transceiver, the Wi-Fi transmitting front-end module, the first power divider, and the antenna in a scenario where Wi-Fi and Bluetooth signals are transmitted simultaneously. It also controls a third switch, a fourth switch, and the first switch to connect the wireless transceiver, the first power amplifier, the first power divider, and the antenna. This allows the first Wi-Fi signal transmitted by the wireless transceiver to be processed by the Wi-Fi transmitting front-end module and then transmitted to the first power divider. The first Bluetooth signal transmitted by the wireless transceiver is also processed by the first power amplifier and then transmitted to the first power divider. The first power divider then aggregates the processed first Wi-Fi signal and the first Bluetooth signal and outputs them to the antenna.

[0079] In some embodiments of this application, the wireless transceiver 401 is also used to control the third switch 408 and the first switch 405 to connect the wireless transceiver 401 to the antenna 406 so as to output the second Bluetooth signal to the antenna 406.

[0080] In this embodiment, when the communication device detects that the Bluetooth module is operating independently, it informs the wireless transceiver. Furthermore, when the wireless transceiver is transmitting a Bluetooth signal independently, and the second Bluetooth signal transmitted by the wireless transceiver meets the strong signal condition, it controls the third switch and the first switch to connect the wireless transceiver to the antenna, so that the second Bluetooth signal is output to the antenna.

[0081] In this embodiment of the application, when a Bluetooth signal is transmitted alone and the second Bluetooth signal transmitted by the wireless transceiver meets the strong signal condition, the third switch and the first switch are controlled to connect the wireless transceiver and the antenna, so that the strong signal output by the first power amplifier can be directly transmitted to the antenna, ensuring that the receiving end can receive the strong signal.

[0082] In some embodiments, a strong signal condition includes: a first quality parameter of the signal being greater than a first threshold; wherein the first quality parameter is positively correlated with the signal quality;

[0083] For example, the first quality parameter may include, but is not limited to, at least one of the following: Received Signal Strength Indicator (RSSI), Reference Signal Received Power (RSRP), Signal-to-Noise Ratio (SNR), etc.

[0084] Alternatively, the second quality parameter of the signal is less than the second threshold; wherein the second quality parameter is negatively correlated with the signal quality.

[0085] For example, the second quality parameter may include, but is not limited to, the Adjacent Channel Leakage Ratio (ACLR).

[0086] In some embodiments of this application, the wireless communication device 400 further includes: a second power divider 410 and a receiving front-end module 411;

[0087] like Figure 7 As shown, the Bluetooth receiver RX port of the wireless transceiver 401 is connected to the second power divider 410, and the WIFI / Bluetooth receiver RX port of the wireless transceiver is connected to the second power divider 410. The second power divider 410 is connected to the antenna 406 through the receiver front-end module 411 and the first switch 405.

[0088] The wireless transceiver 401 is also used to control the connection between the first switch 405, the antenna 406, the receiving front-end module 411, the second power divider 410 and the wireless transceiver 401.

[0089] The receiving front-end module 411 is used to process the aggregated signal received by the antenna 406 to obtain the processed aggregated signal;

[0090] The second power divider 410 is used to split the processed aggregated signal into a third Wi-Fi signal and a third Bluetooth signal;

[0091] Wireless transceiver 401 is used to receive a third Wi-Fi signal and a third Bluetooth signal through a Wi-Fi / Bluetooth receiving port and a Bluetooth receiving port, respectively.

[0092] In this embodiment, when the communication device detects that the Wi-Fi module and Bluetooth module are working simultaneously, it informs the wireless transceiver. Further, in a scenario where the wireless transceiver simultaneously receives Wi-Fi and Bluetooth signals, it controls the connection of the antenna, receiving front-end module, second power divider, and wireless transceiver via a first switch. This ensures that the aggregated signal received by the antenna is processed by the receiving front-end module and transmitted to the second power divider. The second power divider then splits the signal into a third Wi-Fi signal and a third Bluetooth signal, which are then transmitted to the wireless transceiver via the Wi-Fi / Bluetooth receiving port and the Bluetooth receiving port, respectively.

[0093] In this embodiment, a second power divider is provided between the wireless transceiver and the receiving front-end module. The second power divider can split the aggregated signal processed by the receiving front-end module into a third Wi-Fi signal and a third Bluetooth signal, which are then transmitted to the wireless transceiver via the Wi-Fi / Bluetooth receiving port and the Bluetooth receiving port, respectively. Thus, compared to... Figure 2 The proposed solution eliminates the need for an additional Bluetooth antenna, thus avoiding crosstalk between Wi-Fi and Bluetooth signals via antenna radiation. This reduces costs while improving signal transmission efficiency. In other words, it achieves simultaneous reception of Wi-Fi and Bluetooth signals using existing antenna devices.

[0094] In some embodiments of this application, the receiving front-end module includes a signal amplifier and a first filter (e.g., SAW2); wherein, the first switch is connected to the second power divider through the first filter and the signal amplifier;

[0095] Furthermore, in some embodiments, the wireless transceiver is also used to control the connection of the first switch to conduct the antenna, the first filter, the signal amplifier, the second power divider, and the wireless transceiver when simultaneously receiving Wi-Fi and Bluetooth signals and when the aggregated signal meets the weak signal condition. This is so that the aggregated signal received by the antenna is processed by the first filter and the signal amplifier and then transmitted to the second power divider. The second power divider then splits the signal into a third Wi-Fi signal and a third Bluetooth signal, which are then transmitted to the wireless transceiver through the Wi-Fi / Bluetooth receiving port and the Bluetooth receiving port, respectively.

[0096] In this embodiment, when simultaneously receiving Wi-Fi and Bluetooth signals, and the signal strength meets the weak signal condition, the weak aggregated signal is filtered by the first filter, amplified by the signal amplifier, and then output to the wireless transceiver by the second power divider. Even if the signal amplified by the signal amplifier passes through the second power divider, the loss is negligible and does not affect the wireless transceiver's ability to receive strong signals.

[0097] Furthermore, in some embodiments, the wireless transceiver is also used to control the connection between the first switch-on antenna, the first filter, the signal amplifier, the second power divider, and the wireless transceiver;

[0098] The first filter is used to process the fourth Wi-Fi signal or the fourth Bluetooth signal received by the antenna to obtain the filtered fourth Wi-Fi signal or the fourth Bluetooth signal.

[0099] A signal amplifier is used to process the filtered fourth Wi-Fi signal or fourth Bluetooth signal to obtain an amplified fourth Wi-Fi signal or fourth Bluetooth signal.

[0100] The second power divider is also used to output the amplified fourth Wi-Fi signal or fourth Bluetooth signal to the wireless transceiver.

[0101] In this embodiment, when the communication device detects that the Wi-Fi module or Bluetooth module is working, it informs the wireless transceiver. Furthermore, when the wireless transceiver is receiving a Wi-Fi signal or Bluetooth signal alone, and the signal strength meets the weak signal condition, it controls the connection of the first switch to conduct the antenna, the first filter, the signal amplifier, the second power divider, and the wireless transceiver, so that the fourth Wi-Fi signal or fourth Bluetooth signal received by the antenna is output to the wireless transceiver after passing through the first filter, the signal amplifier, and the second power divider.

[0102] In this embodiment, when receiving Wi-Fi or Bluetooth signals alone, and the signal strength meets the weak signal condition, the weak signal is filtered by the first filter, amplified by the signal amplifier, and then output to the wireless transceiver by the second power divider. Even if the signal amplified by the signal amplifier passes through the second power divider, the loss is negligible and does not affect the wireless transceiver's ability to receive strong signals.

[0103] In some embodiments, the weak signal condition includes: a first quality parameter of the signal is less than or equal to a first threshold; wherein the first quality parameter is positively correlated with the signal quality;

[0104] For example, the first quality parameter may include, but is not limited to, at least one of the following: RSSI, RSRP, SNR, etc.

[0105] Alternatively, the second quality parameter of the signal is greater than or equal to the second threshold; wherein the second quality parameter is negatively correlated with the signal quality.

[0106] For example, the second quality parameter may include, but is not limited to, ACLR, etc.

[0107] In some embodiments of this application, the input terminal of the first filter is connected to the output terminal of the signal amplifier;

[0108] Furthermore, in some embodiments, the wireless transceiver is also used to control the connection of the first switch to conduct the antenna, the second power divider, and the wireless transceiver when simultaneously receiving Wi-Fi and Bluetooth signals and the aggregated signal meets the strong signal condition, so that the aggregated signal received by the antenna is directly transmitted to the second power divider, and then split into a third Wi-Fi signal and a third Bluetooth signal by the second power divider, and then transmitted to the wireless transceiver through the Wi-Fi / Bluetooth receiving port and the Bluetooth receiving port, respectively.

[0109] In this embodiment of the application, when receiving both Wi-Fi and Bluetooth signals simultaneously, and the signal strength meets the strong signal condition, the strong aggregated signal received by the antenna is transmitted to the wireless receiver through the second power divider. Even if the strong aggregated signal passes through the second power divider, the loss is negligible and does not affect the wireless transceiver's ability to receive the strong signal.

[0110] Furthermore, in some embodiments, the wireless transceiver is also used to control the connection between the first switch-on antenna, the second power divider, and the wireless transceiver;

[0111] The second power divider is also used to output the fourth Wi-Fi signal or the fourth Bluetooth signal received by the antenna to the wireless transceiver.

[0112] In this embodiment, when the communication device detects that the Wi-Fi module or Bluetooth module is working, it informs the wireless transceiver. Furthermore, when the wireless transceiver is receiving a Wi-Fi signal or Bluetooth signal alone, and the signal strength meets the strong signal condition, it controls the first switch to activate the connection between the antenna, the second power divider, and the wireless transceiver, so that the fourth Wi-Fi signal or fourth Bluetooth signal received by the antenna is output to the wireless transceiver via the second power divider.

[0113] In this embodiment of the application, when receiving Wi-Fi or Bluetooth signals alone, and the signal strength meets the strong signal condition, the strong signal received by the antenna is transmitted to the wireless receiver through the second power divider. Even if the strong signal passes through the second power divider, the loss is negligible and does not affect the wireless transceiver's ability to receive the strong signal.

[0114] In some embodiments, a strong signal condition includes: a first quality parameter of the signal being greater than a first threshold; wherein the first quality parameter is positively correlated with the signal quality;

[0115] For example, the first quality parameter may include, but is not limited to, at least one of the following: RSSI, RSRP, SNR, etc.

[0116] Alternatively, the second quality parameter of the signal is less than the second threshold; wherein the second quality parameter is negatively correlated with the signal quality.

[0117] For example, the second quality parameter may include, but is not limited to, ACLR, etc.

[0118] The following examples illustrate possible implementations of the wireless communication device described in one or more of the above embodiments.

[0119] To address the shortcomings of existing solutions, this application proposes a design scheme for simultaneous Wi-Fi / BT transmission using a power divider. The core idea is to use a power divider to separate and aggregate the Wi-Fi and BT signals. At the transmitting end, when the two signals are aggregated, each signal experiences a 3dB loss before reaching the transmitting port for transmission. Figure 8 The diagram shows the proposed scheme, in which the first power divider is set at the output of the Wi-Fi transmitter and the BT transmitter, and is connected to the two ports of the first power divider respectively, and finally output to the antenna port.

[0120] like Figure 9 As shown, in a scenario where both Wi-Fi and BT signals are transmitted simultaneously, the transceiver controls the SP4T (i.e., a single-pole four-throw switch, corresponding to the first switch) to connect the transceiver, PA Wi-Fi, SAW1, the first power divider, the Couper (i.e., coupler), and the antenna. The transceiver also controls the SP4T (i.e., a single-pole four-throw switch) to connect the transceiver, SPDT1, PABT, the first power divider, the Couper (i.e., coupler), and the antenna. Thus, the transceiver transmits the first Wi-Fi signal via the Wi-Fi transmitter port, which is amplified by the PA Wi-Fi and then filtered by the SAW1 before being output to the first power divider. Similarly, the transceiver transmits the first BT signal via the BT transmitter port, which is output to the first power divider via the PA BT. The first power divider aggregates the processed first Wi-Fi and first BT signals and transmits them to the Couper. After further processing by the Couper, the signals are transmitted to the antenna (i.e., Wi-Fi / BT CHAin0) via the ANT port.

[0121] In scenarios where both Wi-Fi and Bluetooth signals are received simultaneously, the wireless transceiver controls the SP4T (single-pole four-throw switch) to connect the antenna, SAW2, LNA, second power divider, and the wireless transceiver (in weak signal scenarios), or to connect the antenna, second power divider, and the wireless transceiver (in strong signal scenarios). In this way, the aggregated signal received by the antenna is processed by the SAW2 and LNA and then output to the second power divider, or the aggregated signal received by the antenna is directly output to the second power divider. The second power divider splits the aggregated signal into a third Wi-Fi signal and a third Bluetooth signal, and transmits the third Wi-Fi signal and the third Bluetooth signal to the wireless transceiver through the Wi-Fi / BT receiving port and the BT receiving port, respectively.

[0122] like Figure 10 As shown, in Figure 8Based on this, SPDT2 (corresponding to the second switch) is added to the output of SAW1. SPDT2 is connected to the first power divider and SP4T respectively. In this way, when transmitting Wi-Fi signals alone, they do not need to go through the first power divider but are directly output to the antenna, thus eliminating the influence of the first power divider on the Wi-Fi signal and ensuring that the Wi-Fi signal is not lost.

[0123] like Figure 11 As shown, when transmitting a Wi-Fi signal independently, the wireless transceiver controls SPDT2 and SP4T to connect the wireless transceiver, PA Wi-Fi, SAW1, Coupler (i.e., the antenna), so that the wireless transceiver transmits the second Wi-Fi signal through the Wi-Fi transmission port, which is then processed by PA Wi-Fi, SAW1, and Coupler before being transmitted to the antenna through the ANT port. This further improves the performance of the Wi-Fi mode.

[0124] When transmitting a BT signal alone, the transceiver controls SPDT1 (corresponding to the third switch) and SP4T to connect the transceiver, the coupler, and the antenna (in a strong signal scenario), so that the transceiver transmits the second BT signal through the Wi-Fi transmission port, processes it through the coupler, and then transmits it to the antenna through the ANT port. Alternatively, an SPDT4 (corresponding to the fourth switch) can be added to the output of the PA BT, and this SPDT4 is connected to the first power divider and SP4T respectively (in... Figure 11 (Not shown in the image) The wireless transceiver controls SPDT1, SPDT4 and SP4T to connect the wireless transceiver, PA BT, Couper (i.e., coupler) and antenna (in a weak signal scenario), so that the wireless transceiver transmits the second BT signal through the Wi-Fi transmission port to the antenna after processing by PA BT and Couper.

[0125] Thus, by using a power divider, simultaneous transmission of Wi-Fi / BT channels can be achieved on the basis of existing antenna devices, achieving optimal performance, cost, and area.
