[0002] With the development of the Internet, it has become increasingly common for users to use electronic devices (such as mobile phones) for internet access, video streaming, and live broadcasting. Users are demanding higher and higher signal quality and wider range. In some scenarios, such as when users use Wi-Fi technology at home for internet access or video streaming, the access point (AP) device (such as a router) is usually placed in the living room. In these situations, the signal in the bedroom will be relatively weak, especially in rooms separated by two walls. Even if electronic devices show a signal, they may be unable to access the internet or stream videos, resulting in a poor user experience. Summary of the Invention

[0019] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0020] It should be noted that the descriptions involving "first," "second," etc., in the embodiments of this application are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a communication connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] With the development of the internet, it has become increasingly common for users to use electronic devices (such as mobile phones) for internet browsing, video streaming, and live broadcasting. Users are also demanding higher and higher communication quality and range. In some scenarios, when electronic devices are far from the signal source, they cannot access the internet or stream videos, leading to a poor user experience. The following example demonstrates how to use Wi-Fi technology for internet browsing or video streaming in a home environment. Figure 1 Examples will be given to illustrate the above problems.

[0023] In home Wi-Fi scenarios, access point devices (such as routers) are typically placed in the living room. This often results in weaker signals in the bedrooms, especially rooms separated by two walls. Even if electronic devices show a signal, internet access or video calls may be unavailable. The main reasons are as follows:

[0024] See Figure 1 Compared to a conventional electronic device 110 (such as a mobile phone), the access point device 120 has a larger operating radius, with a signal coverage radius of S1. The signal coverage radius of the electronic device 110 is S2. It can be seen that when the distance between the electronic device 110 and the access point device 120 is less than S2, the electronic device 110 can communicate normally (such as accessing the internet or video conferencing). When the distance between the electronic device 110 and the access point device 120 is greater than S2, communication is impossible, mainly because the access point device 120 cannot receive the relevant signaling from the electronic device 110.

[0025] In some embodiments, the electronic device 110 can be a device with data transmission and reception capabilities. Such an electronic device may be, for example, a mobile phone, tablet computer, laptop computer, PDA, mobile internet device (MID), wearable device, virtual reality (VR) device, augmented reality (AR) device, wireless terminal in industrial control, wireless terminal in self-driving, wireless terminal in remote medical surgery, wireless terminal in smart grid, wireless terminal in transportation safety, wireless terminal in smart city, or wireless terminal in smart home, smart screen, etc. This application does not impose specific limitations on this.

[0026] In some embodiments, the access point device 120 may be a routing device or a relay device, etc.

[0027] As described above, improving the signal coverage of electronic devices has become an urgent technical problem to be solved.

[0028] To address the aforementioned issues, research has revealed that many electronic devices currently support satellite communication. As a completely new and independent system, satellite communication requires a dedicated power supply and radio frequency transceiver link. Satellite communication power amplifiers (PAs) typically have high transmit power, resulting in correspondingly high supply voltage and power consumption. The following section will combine... Figure 2 An example is given to illustrate the relationship between the power amplifier's supply voltage and its transmission power.

[0029] Figure 2 This is a schematic diagram of the internal circuitry of a power amplifier provided in an embodiment of this application. See also... Figure 2 The impedance from the input terminal to the output terminal is Z. opt The saturation power P at the collector inside the power amplifier. sat (i.e., the maximum output power of PA) can be:

[0030]

[0031] When Z opt With P remaining unchanged, sat and V cc It is proportional to the square of V, that is, V ccIncrease, P sat Increase accordingly. For example, consider Z. opt =5Ω, V cc When = 3.8V, P sat =1.444W; when V cc When increased to 4.5V, P sat =2.025W.

[0032] Based on the analysis of the relationship between the power amplifier and the supply voltage, in order to solve the above problems, this application provides a radio frequency system, including: a first power amplifier for power amplification of radio frequency signals in the satellite frequency band; a power supply circuit for outputting a first supply voltage; a boost circuit, one end of which is connected to the power supply circuit and the other end of which is connected to the first power amplifier, the boost circuit being used to adjust the first supply voltage to a second supply voltage and to supply power to the first power amplifier using the second supply voltage, wherein the first supply voltage is less than the second supply voltage; a second power amplifier for power amplification of radio frequency signals in the first frequency band; the other end of the boost circuit is connected to the second power amplifier, and the boost circuit is also used to supply power to the second power amplifier using the second supply voltage. Compared with the conventional solution of directly supplying power to the second power amplifier using the power supply circuit, this solution provides a higher second supply voltage to the second power amplifier in the terrestrial communication system by reusing the boost circuit of the satellite communication system, thereby helping to enhance the transmission strength of radio frequency signals in terrestrial communication, helping users to enjoy services such as internet access, video, and live streaming more smoothly, and improving the user experience.

[0033] The following text combines Figure 3 The radio frequency system in the embodiments of this application will be described in detail. For example... Figure 3 As shown, the radio frequency system 300 may include a first power amplifier 310, a power supply circuit 320, a boost circuit 330, and a second power amplifier 340. It should be understood that the radio frequency system 300 may include a satellite radio frequency system and a terrestrial radio frequency system, which are independent of each other. That is, the radio frequency system 300 also includes terrestrial radio frequency transceivers, satellite radio frequency transceivers, and antennas, among other devices.

[0034] Terrestrial radio frequency transceivers can be used to provide radio frequency signals. For example, a terrestrial radio frequency transceiver can provide radio frequency signals in a first frequency band, such as the Wi-Fi 2.4G band or the Wi-Fi 5G band. A terrestrial radio frequency transceiver can also provide radio frequency signals in a second frequency band, such as the Wi-Fi 5G band or the Wi-Fi 2.4G band.

[0035] Satellite radio frequency transceivers can be used to provide radio frequency signals in satellite frequency bands, such as the N255 band or the N256 band.

[0036] The first power amplifier 310 is used to amplify the power of radio frequency signals in the satellite band; the first power amplifier 310 can be any power amplifier in the satellite radio frequency transmission path.

[0037] The power supply circuit 320 is used to output a first supply voltage, which may be, for example, 3.8V; in some embodiments, the first supply voltage may be used to power a power amplifier on the radio frequency transmission path of a terrestrial radio frequency system. The power supply circuit 320 may be, for example, an integrated power supply circuit 320 used to power the radio frequency system 300.

[0038] One end of the boost circuit 330 is connected to the power supply circuit 320, and the other end is connected to the first power amplifier 310. The boost circuit 330 is used to adjust the first supply voltage to a second supply voltage and use the second supply voltage to power the first power amplifier 310. The first supply voltage is less than the second supply voltage. It should be understood that satellite communication requires high-voltage power supply, so a boost circuit 330 is usually set in the radio frequency system 300. As an example, the first supply voltage can be 3.8V, and the second supply voltage can be 4.5V.

[0039] The second power amplifier 340 is used to amplify the power of the radio frequency signal in the first frequency band; the second power amplifier 340 can be a power amplifier on any terrestrial radio frequency transmission path. The first frequency band can be any type of terrestrial communication frequency band. For example, the first frequency band can be the Wi-Fi 2.4G band or the Wi-Fi 5G band.

[0040] The other end of the boost circuit 330 is connected to the second power amplifier 340. The boost circuit 330 is also used to power the second power amplifier 340 using a second supply voltage. Compared to the conventional solution that directly powers the second power amplifier 340 using the power supply circuit 320, this application provides a second supply voltage to the second power amplifier 340 by reusing the boost circuit 330 of the satellite communication system. This helps to enhance the radio frequency signal transmission strength of terrestrial communication, enabling users to enjoy internet access, video streaming, live broadcasting, and other services more smoothly, thus improving the user experience.

[0041] In some embodiments, the radio frequency communication system is applied to an electronic device, and a communication connection is established between the electronic device and the access point device. The power supply circuit 320 is connected to the second power amplifier 340. Figure 4 for Figure 3 The diagram shows another possible structure of the radio frequency system 300.

[0042] See Figure 4The boost circuit 330 is used to power the second power amplifier 340 with a second supply voltage when the distance between the electronic device and the access point device is greater than a preset threshold; the power supply circuit 320 is used to power the second power amplifier 340 with a first supply voltage when the distance between the electronic device and the access point device is less than or equal to the preset threshold. In this embodiment, the boost circuit 330 is reused to power the second power amplifier 340 only when signal enhancement is needed. When signal enhancement is not needed, the power supply circuit 320 can be used to power the second power amplifier 340. This achieves both reduced power consumption and enhanced signal coverage of the electronic device. The electronic device can be any type of electronic device mentioned above, such as those described above. Figure 1 Electronic device 110. This access electronic device can be any type of access point device mentioned above, such as... Figure 1 Access point device 120 in the middle.

[0043] To deepen the understanding of the radio frequency system 300 in the embodiments of this application, the following will be combined with... Figures 5-6 Let's provide more detailed examples.

[0044] Figure 5 for Figure 4 A schematic diagram of another possible structure of the radio frequency system 300 is shown. See also Figure 5 The radio frequency system 300 also includes a switching device 350 and a control circuit 360.

[0045] One end of the switching device 350 is connected to both the boost circuit 330 and the power supply circuit 320, and the other end is connected to the second power amplifier 340. A control circuit 360 is connected to the switching device 350. The control circuit 360 is configured to, in response to a distance greater than a preset threshold, connect one end of the switching device 350 to the boost circuit 330 and disconnect the other end from the power supply circuit 320, thereby supplying power to the second power amplifier 340 using the second supply voltage; and in response to a distance less than or equal to the preset threshold, disconnect one end of the switching device 350 from the boost circuit 330 and connect the other end to the power supply circuit 320, thereby supplying power to the second power amplifier 340 using the second supply voltage. The preset threshold can be set according to requirements; for example, it can be... Figure 1 The radius S2 in the middle.

[0046] In some embodiments, the control circuitry 360 may be integrated into the radio frequency transceiver. In other embodiments, the control circuitry 360 and the radio frequency transceiver may be integrated into a system-on-chip (SOC). This application does not impose any specific limitations on these embodiments.

[0047] In some embodiments, the control circuit 360 may be a processor, such as a central processing unit (CPU). Alternatively, the control circuit 360 may also be other general-purpose processors, digital signal processors (DSPs), application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components, etc. The general-purpose processor may be a microprocessor or any conventional processor.

[0048] It should be noted that the switching device 350 can be a single-pole multi-throw switch. For example, the switching device 350 can be a single-pole double-throw switch.

[0049] Figure 6 for Figure 5 A schematic diagram of another possible structure of the radio frequency system 300 is shown. See also Figure 6 In some embodiments, the radio frequency system 300 further includes a third power amplifier 370. The third power amplifier 370 can be used to amplify the power of the radio frequency signal in the second frequency band; the third power amplifier 370 can be a power amplifier on any terrestrial radio frequency transmission path. The second frequency band can be any type of terrestrial communication band. For example, the second frequency band can be the Wi-Fi 5G band or the Wi-Fi 2.4G band. In some embodiments, the other end of the boost circuit 330 is connected to the third power amplifier 370, and the boost circuit 330 is also used to power the third power amplifier 370 using a second supply voltage. That is, in this solution, the boost circuit 330 can be used to simultaneously power terrestrial radio frequency signals in multiple frequency bands to improve the radio frequency transmission power.

[0050] See also Figure 6In some embodiments, the radio frequency system 300 further includes a first filter circuit 311, a second filter circuit 341, and a third filter circuit 371. One end of the first filter circuit 311 is connected to the first power amplifier 310, and the other end is connected to the antenna. The first filter circuit 311 is used to filter the radio frequency signal amplified by the first power amplifier 310. One end of the second filter circuit 341 is connected to the second power amplifier 340, and the other end is connected to the antenna. The second filter circuit 341 is used to filter the radio frequency signal amplified by the second power amplifier 340. One end of the third filter circuit 371 is connected to the third power amplifier 370, and the other end is connected to the antenna. The third filter circuit 371 is used to filter the radio frequency signal amplified by the third power amplifier 370. The first filter circuit 311, the second filter circuit 341, and the third filter can be used to filter noise in the radio frequency signal on the radio frequency path.

[0051] To deepen understanding of the radio frequency system 300 in this application embodiment, the following example uses a terrestrial radio frequency transceiver supporting two channels of Wi-Fi 2.4G frequency signal transmission and reception and two channels of Wi-Fi 5G frequency signal transmission and reception, combined with... Figure 7 Let's provide more detailed examples. Figure 7 for Figure 6 The diagram shows another possible structure of the radio frequency system 300.

[0052] See Figure 7 The RF system 300 includes two RF front-end modules (FEMs) supporting Wi-Fi 2.4G band signal transmission and reception, namely 2G FEM1 and 2G FEM2. The RF system 300 also includes two RF front-end modules supporting Wi-Fi 5G band signal transmission and reception, namely 5G FEM1 and 5G FEM2. It should be understood that the RF front-end modules 2G FEM1, 2G FEM2, 5G FEM1, and 5G FEM2 may include, but are not limited to, power amplifiers, duplexers, couplers, and switches used in the RF transmission path.

[0053] In some embodiments, system initialization can be performed first, with power supply circuit 320 supplying power to radio frequency system 300. Power supply circuit 320 outputs a first supply voltage, which is boosted by boost circuit 330 to output a second supply voltage (the second supply voltage is higher than the first supply voltage). The second supply voltage output by boost circuit 330 can be supplied to PA2 on the satellite radio frequency transmission path; boost circuit 330 is also used to supply the second supply voltage to switching device 350.

[0054] It should be noted that during system initialization, the control circuit 360 controls the switching device 350, so that the switching device 350 is connected to the power supply circuit 320 and disconnected from the boost circuit 330; at this time, the RF front-end module FEM is powered on, and the voltage is the first supply voltage.

[0055] The satellite RF transceiver outputs RF signals in the satellite frequency band (such as N255 or N265 band). The RF signals in the satellite frequency band are amplified by PA1 and then output to the subsequent filter circuit 1. The signals are then transmitted by the antenna through the transceiver switch. The satellite antenna can receive satellite RF signals, which are then output to the filter circuit 2 through the transceiver switch. After being amplified by PA2, the signals are output to the satellite RF transceiver.

[0056] The terrestrial RF transceiver outputs RF signals in the Wi-Fi 2.4G band and the Wi-Fi 5G band. The Wi-Fi 2.4G band RF signal is amplified by the power amplifier in 2G FEM1 and then output to the subsequent filter circuit 3 before being transmitted by the antenna. The Wi-Fi 2.4G band RF signal is amplified by the power amplifier in 2G FEM2 and then output to the subsequent filter circuit 4 before being transmitted by the antenna. The Wi-Fi 5G band RF signal is amplified by the power amplifier in 5G FEM1 and then output to the subsequent filter circuit 5 before being transmitted by the antenna. The Wi-Fi 5G band RF signal is amplified by the power amplifier in 5G FEM2 and then output to the subsequent filter circuit 6 before being transmitted by the antenna.

[0057] It should be noted that the satellite radio frequency system and the terrestrial radio frequency system are powered independently and operate separately. Generally, satellite communication is used for emergency communication; it is not activated when terrestrial communication signals are available. Therefore, satellite communication should be turned off in such situations. This can be achieved by turning off the power amplifier via its enable pin PA_en. For example, setting PA_en to 0 disables the satellite communication PA.

[0058] In some embodiments, when a user's electronic device moves to a location far from the access point device, such as a bedroom, the electronic device detects a weak communication signal through signal strength detection and needs to activate the wall-penetrating mode. At this time, the control circuit 360 can control the switching device 350 to disconnect the switching device 350 from the power supply circuit 320 and connect the switching device 350 to the boost circuit 330, thereby increasing the power supply voltage of the RF front-end module FEM from the first power supply voltage to the second power supply voltage. This increases the output power of the RF front-end module FEM, thereby improving the signal coverage of the electronic device and ensuring normal communication.

[0059] In some embodiments, when the user's electronic device is in the wild or in an uninhabited area, where there is no cellular network or Wi-Fi signal, the electronic device can initiate satellite communication. In this case, the power supply circuit 320 can be controlled to be in a shutdown state via the control circuit 360; that is, the switching device 350 is disconnected from both the power supply circuit 320 and the boost circuit 330. The RF front-end module (FEM) is not powered, minimizing power consumption and ensuring the electronic device's battery life.

[0060] This embodiment of the application, without changing the existing RF front-end devices, uses a switching device 350 to reuse the output voltage of the boost circuit 330 in the satellite RF system to power the RF front-end module in the terrestrial RF system when the signal is weak. This increases the output voltage of the RF front-end module and improves the signal coverage of the electronic equipment. See also Figure 8 This increases the communication coverage radius of electronic device 110 from S2 to S3. When electronic device 110 moves from position 1 to position 2, and the distance between electronic device 110 and access point device 120 is greater than S2 (e.g., when electronic device 110 moves from the living room to the bedroom), internet access, video streaming, live broadcasting, and other services can still be performed. Of course, the solution in this embodiment can also be used in scenarios such as conference rooms and offices, and this application does not impose specific limitations on it.
