[0026] The present application provides a radio frequency transceiver device 100. Please refer to Figure 1 , the radio frequency transceiver device 100 includes at least two antennas 120, a radio frequency module 110, and a radio frequency transmission link L. The radio frequency module 110 includes a plurality of radio frequency terminals 111, and the radio frequency module 110 is configured to transmit and receive radio frequency signals through the radio frequency terminals 111; the radio frequency transmission link L is electrically connected between the radio frequency terminals 111 and the antennas 120; wherein, the radio frequency transmission link L includes a switching module 130, and the switching module 130 is configured to conduct any one of the radio frequency terminals 111 to any one of the at least two antennas 120; the switching module 130 includes a first switching unit 131 and a second switching unit 132: the first switching unit 131 is connected to the corresponding radio frequency terminal 111 and at least two of the second switching units 132; the second switching unit 132 is connected to at least two of the first switching units 131 to selectively connect to one of the radio frequency terminals 111 and is connected to one of the antennas 120.
[0027] In the above solution, multiple radio frequency terminals 111 of the radio frequency module 110 are connected to the antenna 120 through the first switch unit 131 and the second switch unit 132, and the radio frequency terminals 111 are connected to at least two second switch units 132 through the first switch unit 131, and the second switch unit 132 is connected to the antenna 120. Therefore, the multiple radio frequency terminals 111 of the radio frequency module 110 can be selectively connected to one of the antennas 120 through the first switch unit 131 and the second switch unit 132; moreover, each radio frequency terminal 111 corresponds to a first switch unit 131. Therefore, different radio frequency terminals 111 can be selectively connected to a second switch unit 132 through the corresponding first switch unit 131 and then connected to an antenna 120, which is beneficial to improving the freedom of switching of the radio frequency transmission link L between different antennas 120.
[0028] In some embodiments, as Figure 1 shown, multiple radio frequency terminals 111 of the radio frequency module 110 are respectively connected to a first switch unit 131, and the first switch unit 131 is connected to two second switch units 132, and the two second switch units 132 are connected to different antennas 120. Therefore, by switching the connection between the first switch unit 131 and different second switch units 132, the radio frequency terminal 111 can be connected to different antennas 120, that is, the switching of different radio frequency transmission links L is realized; moreover, since different radio frequency terminals 111 all correspond to a first switch unit 131, different radio frequency terminals 111 can be independently switched without being affected by other radio frequency terminals 111, which is beneficial to improving the freedom of switching of the radio frequency transmission link L between different antennas 120.
[0029] It can be understood that in other embodiments, one of the multiple radio frequency terminals 111 of the radio frequency module 110 may not be limited to being connected to one first switch unit 131, and it may be connected to two or more first switch units 131; the first switch unit 131 is not limited to being connected to two second switch units 132, and it may be connected to two or more second switch units 132; the number of antennas 120 in the radio frequency transceiver device 100 is not limited to two, and may be 3, 4, etc., which is not limited in this application; the second switch unit 132 is not limited to being connected to one of the antennas 120, and it may be connected to two or more antennas 120, which is beneficial to realizing more flexible switching of the radio frequency transmission link L.
[0030] It should be noted that since there are multiple antennas 120 and multiple radio frequency terminals 111 in the radio frequency transceiver device, in order to distinguish different antennas 120 or different radio frequency terminals 111, in this article, reference is also made to Figure 1The antenna 120 is divided into antenna A1 and antenna A2, and the radio frequency terminal 111 is divided into radio frequency terminals T1 to T4. It should be understood that dividing the antenna 120 into antenna A1 and antenna A2, or dividing the radio frequency terminal 111 into radio frequency terminals T1 to T4 is only for distinguishing different radio frequency terminals 111 and different antennas 120 for the convenience of description.
[0031] In some embodiments, the radio frequency module 110 may be configured to respectively transmit and receive radio frequency signals of different frequency bands through a plurality of radio frequency terminals 111. For example, the plurality of radio frequency terminals 111 may be respectively used to transmit and receive radio frequency signals in the WIFI-2.4GHz frequency band, the WIFI-5GHz frequency band, the WIFI-6GHz frequency band, etc. The radio frequency module 110 may be configured to respectively transmit and receive radio frequency signals of different protocols through a plurality of radio frequency terminals 111. For example, the plurality of radio frequency terminals 111 may be respectively used to transmit and receive radio frequency signals in the Bluetooth 2.4GHz frequency band, the WIFI-2.4GHz frequency band, etc.; the radio frequency module 110 may also be configured to respectively transmit and receive radio frequency signals of different protocols or frequency bands through a plurality of radio frequency terminals 111. For example, the plurality of radio frequency terminals 111 may be respectively used to transmit and receive radio frequency signals in the Bluetooth 2.4GHz frequency band, the WIFI-2.4GHz frequency band, the WIFI-5GHz frequency band, the WIFI-6GHz frequency band, etc. Different radio frequency terminals 111 may also be used to transmit and receive radio frequency signals of the same protocol and the same frequency band.
[0032] In some embodiments, please continue to refer to Figure 1 , the switch module 130 includes 4 of the first switch units 131, each of the first switch units 131 is connected to the corresponding radio frequency terminal 111 and two of the second switch units 132; the switch module 130 includes 4 of the second switch units 132, each of the second switch units 132 is connected to two of the first switch units 131 and is connected to one of the antennas 120. It can be understood that in other embodiments, the number of the first switch units 131 in the switch module 130 is not limited to this, and may also be other numbers, which can be selected according to actual needs, and the present application does not make any restrictions.
[0033] In some embodiments, the radio frequency signals accessed by the second switch units 132 connected to the same antenna 120 have different frequency bands.
[0034] Please continue to refer to Figure 1, the second switch unit 132 includes switches E to H, where switches E and G are connected to the same antenna 120, and switches F and H are connected to the same antenna 120; thus, all 4 radio frequency terminals 111 can be connected to the antenna 120 through the first switch unit 131 and the second switch unit 132; for example, the radio frequency terminals T1 / T2 and the radio frequency terminals T3 / T4 can be conducted to the antenna A1 through switches E and G. When the radio frequency terminals T1 / T2 and the radio frequency terminals T3 / T4 simultaneously transmit and receive radio frequency signals through the antenna A1, in order to prevent the two radio frequency signals from interfering with each other, it is necessary to configure the radio frequency terminals T1 / T2 and the radio frequency terminals T3 / T4 to transmit and receive radio frequency signals in different frequency bands.
[0035] In some embodiments, the radio frequency signals in the same frequency band are connected to the antenna 120 through the same second switch unit 132. As Figure 1 shown, the radio frequency terminal T1 and the radio frequency terminal T2 can be configured to transmit and receive radio frequency signals in the 2.4 GHz frequency band, and they are respectively connected to the switch E or the switch F through the switch A and the switch B, so as to be conducted to the antenna A1 or the antenna A2 through the switch E or the switch F. And, the second switch unit 132 is configured to selectively connect to one of the radio frequency terminals 111, that is to say, the switch E or the switch F only conducts one of the radio frequency terminals T1 and the radio frequency terminals T2 to the antenna A1 or the antenna A2. Therefore, multiple radio frequency signals in the same frequency band output by the radio frequency terminals 111 will not be simultaneously transmitted and received in the same antenna 120, thereby reducing the possibility of interference between the radio frequency signals in the same frequency band of different radio frequency terminals 111 and improving the communication efficiency.
[0036] In some embodiments, the switches A to D in the first switch unit 131 and the switches E to H in the second switch unit 132 may include field effect transistors, transistors, integrated circuits including field effect transistors and transistors, or integrated circuits implementing switch functions, which are not limited in this application.
[0037] In some embodiments, the radio frequency module 110 includes a Bluetooth unit and a WiFi unit. The Bluetooth unit is configured to generate the Bluetooth radio frequency signal; the WiFi unit is configured to generate the WiFi radio frequency signal.
[0038] In some embodiments, the radio frequency module 110 may include a Bluetooth chip (not shown in the figure) for outputting the Bluetooth radio frequency signal, a WiFi chip (not shown in the figure) for outputting the WiFi radio frequency signal, or a two-in-one radio frequency chip (not shown in the figure) for outputting the Bluetooth radio frequency signal and the WiFi radio frequency signal, which is not limited in this application.
[0039] In some embodiments, please refer to Figure 2The radio frequency transmission link L further includes a radio frequency signal processing module 210, which is connected to the antenna 120 and the switch module 130.
[0040] In some embodiments, please refer to Figure 3 , the radio frequency signal processing module 210 includes a first processing channel 211 and a second processing channel 212. The first processing channel 211 is configured to process a first radio frequency signal; the second processing channel 212 is configured to process a second radio frequency signal; wherein, the first radio frequency signal and the second radio frequency signal belong to different frequency bands.
[0041] Please combine Figure 2 with Figure 3 , Figure 2 One radio frequency signal processing module 210 in [] is connected to antenna A2, and is also connected to switch F and switch H, and is connected to the four radio frequency terminals 111 of the radio frequency module 110 through switch F, switch H and the first switch module 130. The radio frequency signal processing module 210 includes a first processing channel 211 and a second processing channel 212, which are respectively configured to process a first radio frequency signal and a second radio frequency signal. As described above, different radio frequency terminals 111 can be configured to transmit and receive radio frequency signals of different frequency bands. Assume that radio frequency terminal T2 and radio frequency terminal 111T4 are simultaneously connected to the radio frequency signal processing module 210 through the first switch module 130 and the second switch module 130, and perform radio frequency signal transmission and reception through antenna A2. Since radio frequency terminal T2 and radio frequency terminal 111T4 are configured to transmit and receive radio frequency signals of different frequency bands (for example, radio frequency terminal T2 transmits and receives the first radio frequency signal. Radio frequency terminal 111T4 transmits and receives the second radio frequency signal), the two channels of the radio frequency signal processing module 210 can simultaneously process radio frequency signals of different frequency bands, which is beneficial to improving the communication quality of radio frequency communication in different frequency bands.
[0042] In other embodiments, adapting to the number of carrier frequency bands that the antenna 120 can carry simultaneously, the radio frequency signal processing module 210 may also have other numbers of processing channels, such as 3, 4, etc., which are not limited in this application.
[0043] In some embodiments, please refer to Figure 4 , the radio frequency signal processing module 210 includes a radio frequency transmission path 410, a radio frequency reception path 420, a path selection switch 430, and a duplexer 440. The path selection switch 430 is selectively connected to both ends of the radio frequency transmission path 410 or the radio frequency reception path 420, and is connected to the antenna 120 and the radio frequency module 110; the duplexer 440 is connected between the path selection switch 430 and the radio frequency module 110, and between the path selection switch 430 and the antenna 120.
[0044] In some embodiments, please refer to Figure 5 , the radio frequency (RF) transmitting path 410 may include a power amplifier (PA) for amplifying the input RF signal to meet the requirements of the transmitted signal power, thereby increasing the transmission distance and coverage range of the signal; the RF receiving path 420 may include a low noise amplifier (LNA) and a filter (F). The LNA is used to amplify the weak RF signal received from the antenna 120 while minimizing the introduction of noise, thereby increasing the signal-to-noise ratio of the received signal and ensuring the quality of the received signal. The filter F is used to perform frequency selection on the signal, allowing signals in a specific frequency band to pass through while suppressing interfering signals and noise in other frequency bands, making the signal cleaner.
[0045] When the RF transceiver 100 transmits an RF signal, the RF signal enters from the duplexer 440 on the side close to the RF module 110. The path selection switch 430 turns on the RF transmitting path 410. The RF signal is amplified in power by the power amplifier PA and then transmitted through the antenna 120. When the RF transceiver 100 receives an RF signal, the RF signal enters from the duplexer 440 on the side close to the antenna 120. The path selection switch 430 turns on the RF receiving path 420. The RF signal is first filtered by the filter F to remove interference, then low-noise amplified by the LNA, and finally enters the RF module 110 through the path selection switch 430 and the duplexer 440 on the side close to the RF module 110.
[0046] In some embodiments, the path selection switch 430 may include a field effect transistor, a transistor, an integrated circuit including a field effect transistor and a transistor, or an integrated circuit implementing a switching function. The present application does not limit this here.
[0047] In some embodiments, please refer to Figure 6 , the RF signal processing module 210 includes a first processing channel 211 and a second processing channel 212. Moreover, each processing channel includes an RF transmitting path 410, an RF receiving path 420, and a path selection switch 430. The path selection switch 430 is selectively connected to both ends of the RF transmitting path 410 or the RF receiving path 420 and is connected to the antenna 120 and the RF module 110.
[0048] In some embodiments, please refer to Figure 7, there is also a radio frequency direct connection path 610 between the path selection switch 430 of the radio frequency signal processing module 210. There are no components in the radio frequency direct connection path 610. In specific working modes or frequency band switching scenarios, it may not be necessary to pass through the low noise amplifier LNA and the filter F. The radio frequency signal can be directly transmitted through the radio frequency direct connection path 610 to reduce the loss and delay caused by the signal processing link and improve the signal transmission efficiency. Exemplarily, in the case where high requirements are placed on the signal transmission speed, the signal itself has good quality and little interference, the signal can be quickly transmitted through the radio frequency direct connection path 610. In addition, when the low noise amplifier LNA or the filter F fails or needs to be maintained, calibrated, etc., the radio frequency signal can continue to be transmitted through the radio frequency direct connection path 610, ensuring that the basic functions of the system are still available and avoiding the interruption of the entire signal path due to the failure of intermediate components, enhancing the reliability and fault tolerance of the radio frequency transceiver device 100.
[0049] In some embodiments, please refer to Figure 8 , a reserved jumper 810 can also be connected across both ends of the radio frequency signal processing module 210. Thus, when the radio frequency signal processing module 210 fails, the radio frequency signal can still be transmitted through the reserved jumper 810. Therefore, it is beneficial to improve the reliability and fault tolerance of the radio frequency transceiver device 100.
[0050] In some embodiments, please continue to refer to Figure 8 , the radio frequency signal processing module 210 can also be connected to the radio frequency module 110 through a duplexer 820.
[0051] In some embodiments, each of the radio frequency terminals 111 is configured to receive and transmit one of the Bluetooth 2.4G radio frequency signal, the WIFI 2.4G radio frequency signal, the WIFI 5G radio frequency signal, and the WIFI 6G radio frequency signal.
[0052] A second aspect of the present application provides a terminal device 900. Please refer to Figure 9 , the terminal device 900 includes the radio frequency transceiver device 100 in any of the above embodiments.
[0053] The terminal device 900 may include a camera device, an intelligent door lock, a vehicle-mounted recording device (such as a dash cam), etc.
[0054] In the above solution, multiple radio frequency terminals 111 of the radio frequency module 110 are connected to the antenna 120 through the first switch unit 131 and the second switch unit 132, and the radio frequency terminal 111 is connected to at least two second switch units 132 through the first switch unit 131, and the second switch unit 132 is connected to the antenna 120. Therefore, multiple radio frequency terminals 111 of the radio frequency module 110 can be selectively connected to one of the antennas 120 through the first switch unit 131 and the second switch unit 132; moreover, each radio frequency terminal 111 corresponds to a first switch unit 131. Therefore, different radio frequency terminals 111 can be selectively connected to a second switch unit 132 through the corresponding first switch unit 131 and then connected to an antenna 120, which is beneficial to improving the freedom of switching of the radio frequency transmission link L between different antennas 120.
[0055] A third aspect of the present application provides a radio frequency signal transmission method. Please refer to Figure 10 , and the method includes the following steps:
[0056] Step S10: In response to a transmission request for a first radio frequency signal, determine whether an idle link meets the transmission requirements of the first radio frequency signal; the idle link includes a radio frequency transmission link L that is not currently transmitting a second radio frequency signal, and the second radio frequency signal and the first radio frequency signal belong to the same frequency band.
[0057] Step S20: In response to the idle link meeting the transmission requirements of the first radio frequency signal, transmit the first radio frequency signal through the idle link through the switch module 130.
[0058] Step S30: In response to the idle link not meeting the transmission requirements of the first radio frequency signal, determine whether an occupied link meets the transmission requirements of the first radio frequency signal, and determine whether the idle link meets the transmission requirements of the second radio frequency signal; wherein, the occupied link includes a radio frequency transmission link L that is currently transmitting the second radio frequency signal.
[0059] Step S40: In response to the occupied link meeting the transmission requirements of the first radio frequency signal and the idle link meeting the transmission requirements of the second radio frequency signal, switch the second radio frequency signal to the idle link for transmission through the switch module 130, and transmit the first radio frequency signal through the occupied link.
[0060] In the above solution, multiple radio frequency terminals 111 of the radio frequency module 110 are connected to the antenna 120 through the first switching unit 131 and the second switching unit 132, and the radio frequency terminal 111 is connected to at least two second switching units 132 through the first switching unit 131, and the second switching unit 132 is connected to the antenna 120. Therefore, multiple radio frequency terminals 111 of the radio frequency module 110 can be selectively connected to one of the antennas 120 through the first switching unit 131 and the second switching unit 132; moreover, each radio frequency terminal 111 corresponds to a first switching unit 131. Therefore, different radio frequency terminals 111 can be selectively connected to a second switching unit 132 through the corresponding first switching unit 131 and then connected to an antenna 120, which is beneficial to improving the freedom of switching of the radio frequency transmission link L between different antennas 120.
[0061] The first radio frequency signal and the second radio frequency signal belong to the same frequency band. For example, the first radio frequency signal can be a Bluetooth 2.4 GHz radio frequency signal output by one of the radio frequency terminals 111 of the radio frequency module 110, and the second radio frequency signal can be a WiFi-2.4 GHz radio frequency signal output by another radio frequency terminal 111; or, the first radio frequency signal can be a Bluetooth 2.4 GHz radio frequency signal output by one of the radio frequency terminals 111 of the radio frequency module 110, and the second radio frequency signal can be a Bluetooth 2.4 GHz radio frequency signal output by another radio frequency terminal 111, and so on.
[0062] In some embodiments, each radio frequency terminal 111 can send data to the antenna 120 through different radio frequency transmission links L respectively, and record the optimal radio frequency transmission link L according to the feedback information of the router and the terminal, so as to select the optimal link for data transmission when there is a data request.
[0063] In the actual use scenario, there is a scenario where a first radio frequency signal (such as a WiFi-2.4 GHz radio frequency signal) and a second radio frequency signal (such as a Bluetooth 2.4 GHz radio frequency signal) need to be transmitted simultaneously. However, since radio frequency signals in the same frequency band will cause significant interference when transmitted through the same antenna 120, which affects the communication quality, it is necessary to transmit the first radio frequency signal and the second radio frequency signal through different antennas 120 respectively.
[0064] In some embodiments, when there is a simultaneous transmission request for WiFi 5G signal and WiFi 6G signal, since the data transmission volume of both is relatively large, an equalization mode is adopted. According to the data sizes required for transmission of the WiFi5G signal and the WiFi 6G signal, the data transmission volume on the two antennas 120 is balanced, so that the data transmission volumes of both can meet the requirements and ensure the data transmission quality of WiFi 5G and WiFi 6G.
[0065] In some embodiments, the RF signal of WiFi-2.4GHz has a higher priority than the RF signal of Bluetooth 2.4GHz. That is to say, it is necessary to prioritize ensuring that the RF signal of WiFi-2.4GHz transmits data in the optimal link.
[0066] Exemplarily, when data is transmitted through the RF signal of WiFi-2.4GHz and the RF module 110 also transmits data through the RF signal of Bluetooth 2.4GHz, it can first be evaluated whether the use of the idle link by the RF signal of Bluetooth 2.4GHz can meet the data transmission requirements. If it can be met, the idle RF transmission link L is used; if not, it is evaluated whether the use of the idle link by the RF signal of WiFi-2.4GHz can meet the data transmission requirements. If it can be met, the RF signal of Bluetooth 2.4GHz switches to the occupied link for data transmission, and the RF signal of WiFi-2.4GHz switches to the idle link for transmission; if the use of the idle link by the RF signal of WiFi-2.4GHz cannot meet the transmission requirements, the RF signal of WiFi-2.4GHz still uses the current RF transmission link L, and the RF signal of Bluetooth 2.4GHz uses the idle link for data transmission. When the RF transmission link L used by the RF signal of WiFi-2.4GHz is idle, the RF signal of Bluetooth 2.4GHz then switches to the optimal link for data transmission.
[0067] As another example, when data is transmitted through the RF signal of Bluetooth 2.4GHz and at this time the RF module 110 also transmits data through the RF signal of WiFi-2.4GHz, it is first evaluated whether the use of the idle link by the RF signal of WiFi-2.4GHz can meet the data transmission requirements. If it can be met, the idle link is used; if not, it is evaluated whether the use of the idle link by the RF signal of Bluetooth 2.4GHz can meet the data transmission requirements. If Bluetooth can meet it, the RF signal of WiFi-2.4GHz switches to the optimal transmission link, and the RF signal of Bluetooth 2.4GHz switches to the idle link. If the use of the idle link by the RF signal of Bluetooth 2.4GHz cannot meet the transmission requirements, the RF signal of WiFi-2.4GHz selects the optimal link for data transmission, and the RF signal of Bluetooth 2.4GHz maintains data transmission on another link. When the RF transmission link L where the RF signal of WiFi-2.4GHz is located is idle, the RF signal of Bluetooth 2.4GHz then switches to the optimal link.
[0068] The above scheme is beneficial to the simultaneous transmission of the Bluetooth RF signal and the RF signal of WiFi 2.4GHz.
[0069] It will be apparent to those skilled in the art that many modifications and variations can be made to the apparatus and methods while remaining within the teachings of the present application. Accordingly, the foregoing disclosure should be considered to be limited only by the scope of the appended claims.
