Furthermore, the satellite communication circuit module 30 includes an accessory circuit board 301, a satellite communication chip 302, and a radio frequency front-end circuit 303.

[0059] It is understood that in this embodiment, the electronic device 100 supplies power to the first radio frequency device 330 via wired power supply, and supplies power to the satellite communication chip 302 and the second radio frequency device 331 via wireless power supply.

[0060] The first radio frequency device 330 includes, but is not limited to, one or more of a power amplifier, a filter, and a low-noise amplifier.

[0067] When the voltage converter 306 is a DC-DC boost converter, it is used to boost the voltage of the DC power output from the power supply port 402 before transmitting it to the power amplifier. The DC-DC boost converter can meet the high voltage requirements of the power amplifier.

[0068] This embodiment includes at least one power amplifier in at least one first radio frequency device 330, and at least one voltage conversion device 306 disposed on the accessory circuit board 301 in the satellite communication circuit module 30. This can meet the high power requirements of the power amplifier, and the power supply circuit of the power amplifier is different from the power supply circuit of the satellite communication chip 302 and the second radio frequency device 331, which can avoid the satellite communication circuit module 30 from generating high heat.

[0070] Understandably, in this embodiment, the first antenna radiator 201 serves as a transmitting antenna, and the second antenna radiator 202 serves as a receiving antenna. The first antenna radiator 201 and the second antenna radiator 202 can be located at any clear location on the accessory body 10. In one possible embodiment, the first antenna radiator 201 can be located at the second edge 102 of the accessory body 10, and the distance between the first antenna radiator 201 and the first edge 101 of the accessory body 10 is less than the distance between the first antenna radiator 201 and the third edge 103 of the accessory body 10. The second antenna radiator 202 can be located at the fourth edge 104 of the accessory body 10, and the distance between the second antenna radiator 202 and the first edge 101 of the accessory body 10 is less than the distance between the second antenna radiator 202 and the third edge 103 of the accessory body 10.

[0071] Transmitting path 332 is used to transmit signals from satellite communication chip 302 to antenna radiator 20. Receiving path 334 is used to transmit signals from antenna radiator 20 to satellite communication chip 302. There can be one or more transmitting paths 332, and one or more receiving paths 334. The number of transmitting paths 332 and the number of receiving paths 334 can be the same or different. In embodiments implementing BeiDou satellite communication, there can be one transmitting path 332 and multiple receiving paths 334, including but not limited to two. In embodiments implementing Tiantong satellite communication, there can be one transmitting path 332 and one receiving path 334.

[0072] In one possible embodiment, the satellite communication circuit module 30 includes a first antenna port 340 and a second antenna port 341 disposed on an accessory circuit board 301. One end of the transmitting path 332 is electrically connected to the satellite communication chip 302, and the other end of the transmitting path 332 is electrically connected to the first antenna radiator 201 through the first antenna port 340. One end of the receiving path 334 is electrically connected to the satellite communication chip 302, and the other end of the receiving path 334 is electrically connected to the second antenna radiator 202 through the second antenna port 341.

[0073] The transmission path 332 includes at least one power amplifier. In one possible embodiment, the satellite communication circuit module 30 further includes a first filter 391 disposed on an accessory circuit board 301 and electrically connected between the power amplifier in the transmission path 332 and the satellite communication chip 302. The first filter 391 is used to reduce signal interference between the power amplifier and the satellite communication chip 302.

[0074] In this embodiment, different antenna radiators 20 are used for transmitting and receiving, which can reduce intermodulation interference and improve the performance of the antenna radiators 20 in transmitting and receiving satellite communication signals.

[0075] Of course, in other possible implementations, the transmitter and receiver can share the same antenna radiator 20, in which case the transmitter path 332 and the receiver path 334 are electrically connected to the same antenna radiator 20.

[0076] like Figure 14 As shown, in one possible implementation, the at least one receiving path 334 includes a first receiving path and a second receiving path. The radio frequency front-end circuit 303 also includes a switching switch 307, one end of which is electrically connected to the second antenna radiator 202, and the other end of which electrically switches the connection between the first receiving path and the second receiving path.

[0077] The switching switch 307 includes, but is not limited to, a single-pole double-throw switch or a single-pole four-throw switch. When the other end of the switching switch 307 is electrically connected to the first receiving path, the satellite communication signal received by the second antenna radiator 202 can be transmitted through the first receiving path to the satellite communication chip 302, and then through the satellite communication chip 302 and the accessory interface 40 to the electronic device 100. When the other end of the switching switch 307 is electrically connected to the second receiving path, the satellite communication signal received by the second antenna radiator 202 can be transmitted through the second receiving path to the satellite communication chip 302, and then through the satellite communication chip 302 and the accessory interface 40 to the electronic device 100.

[0078] This embodiment, by designing a first receiving path and a second receiving path, and by switching the first receiving path and the second receiving path electrically connected by a switch 307, enables the device accessory 200 to simultaneously support BeiDou and TianTong satellite communication.

[0079] In one possible implementation, the first receiving path includes at least one first low noise amplifier (LNA) 3340. The second receiving path includes at least one second low noise amplifier 3341. The satellite communication circuit module 30 further includes a control line 308 disposed on the accessory circuit board 301. One end of the control line 308 is electrically connected to the satellite communication chip 302, and the other end is electrically connected to the second low noise amplifier 3341.

[0080] In one possible embodiment, the number of first low-noise amplifiers 3340 can be multiple, including but not limited to two, three, or four. This embodiment uses two first low-noise amplifiers 3340 as an example. The two first low-noise amplifiers 3340 are connected in series. The number of second low-noise amplifiers 3341 can be one. Of course, in other possible embodiments, the number of first low-noise amplifiers 3340 can be one, or the number of second low-noise amplifiers 3341 can be multiple.

[0081] In one possible embodiment, the satellite communication circuit module 30 further includes a second filter 392 disposed on the accessory circuit board 301 and electrically connected between the first low-noise amplifier 3340 and the satellite communication chip 302. The second filter 392 is used to reduce signal interference between the first low-noise amplifier 3340 and the satellite communication chip 302. The satellite communication circuit module 30 also includes a third filter 393 disposed on the accessory circuit board 301 and electrically connected between the second low-noise amplifier 3341 and the satellite communication chip 302, and a fourth filter 394 electrically connected between the second low-noise amplifier 3341 and the second antenna port 341. The third filter 393 is used to reduce signal interference between the second low-noise amplifier 3341 and the satellite communication chip 302. The fourth filter 394 is used to reduce signal interference between the second low-noise amplifier 3341 and the second antenna radiator 202.

[0082] The control circuit 308 can be located on the accessory circuit board 301. This can be achieved by directly molding the control circuit 308 onto the accessory circuit board 301, including but not limited to printing it on the accessory circuit board 301, or by mounting the control circuit 308 onto the accessory circuit board 301. The control circuit 308 can control the noise suppression, signal amplification, and impedance matching of the second low-noise amplifier 3341, thereby balancing the noise figure and gain of the second low-noise amplifier 3341.

[0083] like Figure 15 As shown, this application also provides an electronic component 1000. The electronic component 1000 includes an electronic device 100 and a device accessory 200 as described in any of the above embodiments. The electronic device 100 includes a device interface 11, which is connected to the accessory interface 40 in a satellite communication scenario.

[0084] The device interface 11 includes, but is not limited to, a Type-C interface, a USB interface, or a Lightning interface. The device interface 11 and the accessory interface 40 can be connected via a wired connection.

[0085] In addition, the electronic device 100 may also include at least one device circuit board, a battery, a cellular communication module, a Bluetooth communication module, a Wi-Fi communication module, a display screen, a camera, etc. The antenna portions of the cellular communication module, Bluetooth communication module, and Wi-Fi communication module may be located on the casing of the electronic device 100, including but not limited to the frame of the electronic device 100. The radio frequency circuits of the cellular communication module, Bluetooth communication module, and Wi-Fi communication module may be located on the device circuit board. After the device interface 11 is connected to the accessory interface 40, the battery of the electronic device 100 can power the satellite communication chip 302 and the radio frequency front-end circuit 303 of the device accessory 200.

[0086] like Figure 16 As shown, Figure 16 This is a schematic flowchart illustrating a satellite communication method provided in an embodiment of this application. The satellite communication method is executed on the electronic component 1000 described in any of the above embodiments. The satellite communication method includes, but is not limited to, the following steps S10 and S20.

[0087] S10: Control the connection between the device interface 11 and the accessory interface 40.

[0088] S20: Enables the transmission and / or reception of satellite communication signals.

[0089] In step S10, the connection between the control device interface 11 and the accessory interface 40 can be a physical connection or a software connection. The software connection between the control device interface 11 and the accessory interface 40 can be achieved through methods including, but not limited to, displaying a pop-up window on the electronic device 100, allowing the user to confirm whether to connect.

[0090] In step S20, during the transmission of satellite communication signals, the satellite communication signals (including but not limited to edited text messages, calls to target numbers, etc.) transmitted by the electronic device 100 are transmitted to the satellite communication chip 302 through the device interface 11 and the accessory interface 40, and then transmitted to the antenna radiator 20 through the radio frequency front-end circuit 303, from which they are transmitted to the satellite. During the reception of satellite communication signals, the antenna radiator 20 receives the downlink signals transmitted by the satellite, transmits them to the satellite communication chip 302 through the radio frequency front-end circuit 303, and then transmits them to the electronic device 100 through the accessory interface 40 and the device interface 11.

[0091] In one possible embodiment, the electronic device 100 may have a satellite communication application (APP) to transmit / receive satellite communication signals, including entering the satellite communication application to transmit / receive satellite communication signals. After entering the satellite communication application, the electronic device 100 may enter flight mode.

[0092] In one possible implementation, such as Figure 17 As shown, after step S20, the satellite communication method may further include the following step S30.

[0093] S30: Disconnect the device interface 11 from the accessory interface 40.

[0094] The disconnection of the control device interface 11 from the accessory interface 40 can be a physical separation of the control device interface 11 and the accessory interface 40, and / or a software disconnection of the control device interface 11 and the accessory interface 40. In one possible embodiment, the physical separation of the control device interface 11 from the accessory interface 40 can be achieved by detaching the device accessory 200 from the electronic device 100. When the control device interface 11 and the accessory interface 40 are disconnected, the electronic device 100 can display a pop-up window to remind the user to perform the disconnection operation.

[0095] This application places the satellite communication module on the device accessory 200, which allows for a more flexible and sufficient layout of the circuit board of the electronic device 100. This facilitates the placement of emerging ultra-high frequency (UHF) radio frequency circuit modules (e.g., N78, N41, etc.). Furthermore, the electronic device 100 does not require a satellite antenna, ensuring the efficiency of other antennas on the device 100 and maintaining isolation between antennas in multi-antenna configurations. This reduces antenna tuning and allows for further optimization of the antenna structure. The satellite antenna on the device accessory 200 can also be designed as a high-efficiency antenna, achieving optimal antenna efficiency. In addition, supporting satellite communication for the electronic device 100 through the device accessory 200 reduces the cost of the electronic device 100, increases the versatility of the electronic device 100 model, and meets diverse user needs.

[0096] The features mentioned above in the specification, claims, and drawings can be combined in any way as long as they are meaningful within the scope of this application. The advantages and features described with respect to device accessory 200 are applied accordingly to electronic component 1000 and satellite communication method.

[0097] Although embodiments of this application have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this application. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application, and such improvements and refinements are also considered to be within the protection scope of this application.
