Description

Technical Field

[0001] The present disclosure relates to the field of radio frequency technology, and in particular to a radio frequency system, a radio frequency signal transmission method, a radio frequency device, and a terminal. Background Art

[0002] As the number of terminal standards and frequency bands increases, the number of transmission paths between the terminal's RF chip and antenna also increases. However, due to the limited space in mobile phones, the number of antennas is also limited, that is, many frequency bands share one antenna. Therefore, the setting of the transmission path involves RF switching in the terminal. Each device has an impact on the transmission performance of the transmission path, thus affecting the entire communication system.

[0003] In related technologies, terminals usually use a fixed single RF transmission path to control the transmission path. Since the transmission path is fixed, the resource loss in the transmission path is also fixed. Even if there is a transmission path with less loss during the transmission process, the terminal cannot switch. This results in more redundancy and complexity in the design, increases design costs, and has a greater impact on performance. Summary of the invention

[0042] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0043] Before introducing the specific implementation methods of the present disclosure in detail, the application scenarios of the present disclosure are first described. At present, with the increasing complexity of the functions of the terminal, there are more and more terminal formats and frequency bands, resulting in a large number of transmission paths between the terminal's RF chip and the antenna. For example, the same mobile phone must be compatible with most of the functions in cellular mobile communications, WIFI, Bluetooth, and the Global Positioning System (GPS), and needs to meet the frequency band requirements of 2G / 3G / 4G / 5G, covering frequency bands ranging from 600M-6GHZ. In order to pursue higher data transmission rates, it is also necessary to implement multiple input multiple output (MIMO), that is, multiple antennas and multiple carrier aggregation (CA) technology. There will be more than 30 frequency bands for mobile phones and more than 10 antennas. Each frequency band, such as the B1 frequency band, is divided into four MIMO channels: main set, diversity, main MIMO, and sub-MIMO. Each channel is divided into more than 4-20 branch paths due to different physical devices, so there may be more than 20 RF transmission paths for each frequency band.

[0044] In related technologies, a single 3P3T switch is usually used to connect the antenna and multiple RF first-launch circuits. However, the 3P3T switch has high design costs and large insertion losses, which increases the difficulty of antenna debugging and reduces the main diversity transmit power and main diversity receive sensitivity performance of the terminal frequency band and the MIMO reception performance.

[0045] In order to overcome the technical problems existing in the above-mentioned related technologies, the present disclosure provides a radio frequency system, which includes multiple transceiver components and a switching circuit; the switching circuit includes multiple switch components connected in series; the multiple transceiver components are connected to the multiple switch components, and the transceiver frequency band range supported by each transceiver component matches the switching frequency band range supported by the connected switch component.

[0046] In this way, the corresponding transmission path can be matched and flexibly adjusted according to the frequency band range supported by the transceiver component and the frequency band of the transmitted RF signal through the connected multiple switch components, which can reduce the resource loss of the communication system, reduce the difficulty of antenna debugging, and improve signal transmission performance.

[0047] The present disclosure is described below in conjunction with specific embodiments.

[0048] Figure 1 FIG. 1 is a block diagram of a radio frequency system according to an exemplary embodiment. Figure 1 As shown, the radio frequency system 100 includes a transceiver circuit and a switch circuit 102; the switch circuit 102 includes a plurality of switch components 1021 connected in series; the transceiver circuit includes a plurality of transceiver components 101, the plurality of transceiver components 101 are connected to the plurality of switch components 1021, and the transceiver frequency band range supported by each transceiver component 101 matches the switch frequency band range supported by the connected switch component 1021.

[0049] The transceiver component 101 may include a radio frequency transceiver circuit and an antenna.

[0050] In the present disclosure, the RF system 100 can be integrated into a terminal used for wireless communication, such as a mobile phone, a tablet, a laptop computer, etc. The RF system 100 can use an antenna to receive a communication signal from a base station, and then transmit the communication signal from the base station to the RF transceiver circuit after filtering, amplifying, and other processing. Alternatively, the baseband signal received by the RF transceiver circuit can be converted into a RF signal, and the RF signal is transmitted to the antenna for sending the RF signal. In this way, the RF system 100 can realize the transceiver communication of the terminal.

[0051] For example, the RF transceiver circuit may include transceiver circuits with different circuit frequency bands; in one possible implementation, the RF transceiver circuit may receive a RF signal sent by a 4G baseband module, and when the signal is in the uplink transmission direction, the RF signal may be subjected to, for example, modulation, filtering and shaping, digital-to-analog conversion, and up-conversion processing, and then converted into a 4G RF signal of a different frequency band and output to the antenna for transmission, and when the signal is in the uplink transmission direction, the RF transceiver circuit may receive a communication signal from the base station sent by the antenna. In another possible implementation, the RF transceiver circuit may also receive a RF signal sent by a 5G baseband module, and when the signal is in the uplink transmission direction, the RF signal may be subjected to, for example, modulation, filtering and shaping, digital-to-analog conversion, and up-conversion processing, and then converted into a 5G RF signal of a different frequency band and output to the antenna for transmission, and when the signal is in the uplink transmission direction, the RF transceiver circuit may receive a communication signal from the base station sent by the antenna.

[0052] By adopting the above technical solution, the radio frequency system 100 includes a transceiver circuit and a switch circuit 102; the switch circuit 102 includes a plurality of switch components 1021 connected in series; the transceiver circuit includes a plurality of transceiver components 101, the plurality of transceiver components 101 are connected to the plurality of switch components 1021, and the transceiver frequency band range supported by each transceiver component 101 matches the switch frequency band range supported by the connected switch component 1021. In this way, the corresponding transmission path can be matched and flexibly adjusted according to the frequency band range supported by the transceiver component 101 and the frequency band of the transmitted radio frequency signal through the connected plurality of switch components 1021, which can reduce the resource loss of the communication system, reduce the difficulty of antenna debugging, and improve the signal transmission performance.

[0053] In some embodiments, Figure 2 As shown, the radio frequency transceiver circuit can be connected to the antenna through the multiple switch components 1021.

[0054] Optionally, a radio frequency signal can be transmitted between the radio frequency transceiver circuit and the antenna through the multiple switch components 1021. The radio frequency transceiver circuit may include multiple transceiver circuits, each corresponding to different circuit radio frequency ranges. For example, one radio frequency transceiver circuit may correspond to the B41 frequency band of 4G, and one radio frequency transceiver circuit may correspond to the N41 frequency band of 5G. The frequency ranges of the B41 frequency band and the N41 frequency band overlap (both are 2496Mhz-2690Mhz).

[0055] By way of example, the multiple RF transceiver circuits can be connected to the multiple switch components 1021, and the circuit frequency band range supported by each RF transceiver circuit matches the switching frequency band range supported by the connected switch component 1021; and the multiple switch components 1021 can also be connected to the antenna respectively, and the antenna frequency band range supported by the antenna matches the switching frequency band range supported by the connected switch component 1021.

[0056] Optionally, the antenna may include multiple antennas, for example, may include a first antenna, a second antenna, and a third antenna; wherein the multiple switch components 1021 may also be connected to the multiple antennas respectively, and the antenna frequency band range supported by each antenna matches the switching frequency band range supported by the connected switch component 1021.

[0057] In a possible implementation, each RF transceiver circuit may be connected to one of the switch components 1021, and multiple switch components 1021 may be connected in series, wherein the number of the RF transceiver circuits is consistent with the number of the switch components 1021, and the circuit RF range supported by each RF transceiver circuit may match the second RF range of the connected switch component 1021. Specifically, the circuit RF range supported by each RF transceiver circuit may be consistent with the second RF range of the connected switch component 1021, or the circuit RF range supported by each RF transceiver circuit may be within the second RF range of the connected switch component 1021. In this way, when the antenna receives a RF signal, the RF signal may be transmitted to the RF transceiver circuit connected to the switch component 1021 according to the frequency band of the RF signal through the switch component 1021 that supports the frequency band.

[0058] In another possible implementation, each RF transceiver circuit may be connected to any switch component 1021, and multiple switch components 1021 may be connected in series, wherein the circuit RF range supported by each RF transceiver circuit may match the total second RF range of all connected switch components 1021. Specifically, the circuit RF range supported by each RF transceiver circuit may be consistent with the total second RF range of all connected switch components 1021, or the circuit RF range supported by each RF transceiver circuit may include the total second RF range of all connected switch components 1021, so that when the antenna receives a RF signal, the RF signal may be transmitted to the RF transceiver circuit corresponding to the frequency band of the RF signal through the switch component 1021 supporting the frequency band according to the frequency band of the RF signal through multiple connected switch components 1021.

[0059] In some embodiments, the radio frequency transceiver circuit includes a first radio frequency transceiver circuit and a second radio frequency transceiver circuit.

[0060] Optionally, the switch component 1021 connects the first RF transceiver circuit to the antenna, and connects the second RF transceiver circuit to the antenna.

[0061] Among them, the switch component 1021 is used to determine the target transceiver component 101 from multiple transceiver components 101 according to the frequency band corresponding to the radio frequency signal and the transceiver frequency band range, and to determine the target switch component 1021 connected to the target transceiver component 101 from the multiple switch components 1021 according to the frequency band and the switch frequency band range, and transmit the radio frequency signal through the target path between the target transceiver component 101 and the target switch component 1021.

[0062] And the switch circuit may include a first switch component and a second switch component; the first switch component and the second switch component are connected.

[0063] Optionally, the first switch component can be used to connect the RF transceiver circuit and the antenna; the second switch component can be used to connect the RF transceiver circuit and the antenna. The circuit frequency band range supported by the RF transceiver circuit is within the superimposed frequency band range, which is the superimposed frequency band range of the switching frequency band range supported by the first switch component and the switching frequency band range supported by the second switch component.

[0064] For example, the switch assembly 1021 may include a first DPDT switch and a second DPDT switch.

[0065] The first DPDT switch connects the first RF transceiver circuit with the antenna, and connects the second RF transceiver circuit with the antenna; the first circuit frequency band range supported by the first RF transceiver circuit matches the superimposed frequency band range, and the superimposed frequency band range is the superimposed frequency band range of the switching frequency band range supported by the first DPDT switch and the switching frequency band range supported by the second DPDT switch; the second DPDT switch 1021 connects the first RF transceiver circuit with the antenna, and connects the second RF transceiver circuit with the antenna; the transceiver frequency band range supported by the second RF transceiver circuit matches the superimposed frequency band range.

[0066] Optionally, the antenna is used to represent an antenna system and may include multiple antennas, for example, may include a first antenna, a second antenna, and a third antenna.

[0067] In one possible implementation, Figure 3 As shown, the switch component 1021 may include a switch component-DPDT switch A and a switch component-DPDT switch B, a first RF transceiver circuit may be connected to the switch component-DPDT switch A, and a second RF transceiver circuit may be connected to the switch component-DPDT switch B, wherein the circuit RF range of the first RF transceiver circuit may be consistent with the switching frequency band range supported by the connected switch component-DPDT switch A, or the circuit RF range of the first RF transceiver circuit may include the switching frequency band range supported by the switch component-DPDT switch A, so that when any of the first antenna, the second antenna, and the third antenna, for example, the first antenna receives a RF signal, the RF signal may be transmitted to the RF transceiver circuit connected to the switch component 1021 according to the frequency band of the RF signal through the switch component 1021 that supports the frequency band.

[0068] For example, when the frequency band of the RF signal received by the first antenna is (a, c), the circuit frequency band range of the first RF transceiver circuit is (a, d), and the circuit frequency band range of the second RF transceiver circuit is (c, e), wherein a, b, c, and d are values ​​arranged from small to large. In this way, the first RF transceiver circuit can be determined as the target RF transceiver circuit according to the frequency band of the RF signal, and then the switch component - DPDT switch A connected to the first RF transceiver circuit can be used as the target switch component. Finally, the RF signal can be transmitted through the target path between the target transceiver component (the first RF transceiver circuit, antenna) and the target switch component (switch component - DPDT switch A).

[0069] In another possible implementation, Figure 4 As shown, the switch component 1021 may include a switch component-DPDT switch A, a switch component-DPDT switch B, ..., a switch component N; a first RF transceiver circuit may be connected to the switch component-DPDT switch A, and a second RF transceiver circuit may be connected to the switch component-DPDT switch B, wherein the circuit RF range of the first RF transceiver circuit may be consistent with the total switching frequency band range supported by all connected switch components 1021, or the circuit RF range of the first RF transceiver circuit may include the total switching frequency band range supported by all connected switch components 1021, so that when any antenna among the first antenna, the second antenna, and the third antenna, for example, the second antenna receives a RF signal, according to the frequency band of the RF signal, the RF signal can be transmitted to the RF transceiver circuit corresponding to the frequency band of the RF signal through multiple connected switch components 1021.

[0070] For example, when the frequency band of the RF signal received by the second antenna is (a, c), the circuit frequency band range of the first RF transceiver circuit is (a, d), and the circuit frequency band range of the second RF transceiver circuit is (c, e), and a, b, c, and d are numerical values ​​arranged from small to large. In this way, the first RF transceiver circuit can be determined as the target RF transceiver circuit based on the frequency band of the RF signal, and then when the antenna receives the RF signal, the RF signal can be transmitted to the RF transceiver circuit corresponding to the frequency band of the RF signal through multiple connected switch components 1021 according to the frequency band of the RF signal.

[0071] In some embodiments, the switch assembly 1021 includes a plurality of ports.

[0072] Optionally, the multiple ports correspond to different preset frequency band ranges, and the preset frequency band range is a sub-range of the switching frequency band range; the port includes a first port connected to the radio frequency transceiver circuit and a second port connected to the antenna.

[0073] Among them, the preset frequency band range supported by the first port matches the circuit frequency band range of the connected RF transceiver circuit; the preset frequency band range supported by the second port matches the antenna frequency band range of the connected antenna.

[0074] In some embodiments, the switch component 1021 includes a plurality of ports, including at least one connection port, where the connection port is used to connect with other switch components 1021 .

[0075] Figure 5 is a flow chart of a radio frequency signal transmission method according to an exemplary embodiment. Figure 5 As shown, the method is applied to a radio frequency system, which includes multiple transceiver components and a switching circuit, and the switching circuit includes multiple switch components connected in series; the multiple transceiver components are connected to the multiple switch components, and the transceiver frequency band range supported by each transceiver component matches the switching frequency band range supported by the connected switch component; the method includes the following steps.

[0076] In step S11, a frequency band corresponding to the radio frequency signal to be transmitted is obtained.

[0077] The radio frequency signal is a signal transmitted between the transceiver component and the switch component. The transceiver component includes a radio frequency transceiver circuit and an antenna. The radio frequency transceiver circuit is connected to the antenna through the multiple switch components. The radio frequency signal is transmitted between the radio frequency transceiver circuit and the antenna through the multiple switch components.

[0078] In this step, since both the RF transceiver circuit and the antenna have the ability to receive and send signals, when the antenna receives a signal sent by a base station, the RF signal to be transmitted obtained is the signal sent by the antenna to the RF transceiver circuit; when the RF transceiver circuit sends a signal to the antenna, the RF signal to be transmitted obtained is the signal sent by the RF transceiver circuit to the antenna.

[0079] In step S12, a target transceiver component is determined from a plurality of transceiver components according to the frequency band and the transceiver frequency band range.

[0080] The transceiver assembly includes a radio frequency transceiver circuit and an antenna, the radio frequency transceiver circuit is connected to the antenna through the plurality of switch assemblies, the transceiver frequency band range includes a circuit frequency band range corresponding to the radio frequency transceiver circuit and an antenna frequency band range corresponding to the antenna. And the target transceiver assembly may include a target radio frequency transceiver circuit and a target antenna.

[0081] In this step, after determining the frequency band range of the RF signal, the target RF transceiver circuit can be determined from multiple RF transceiver circuits, and the target antenna can be determined from multiple antennas according to the circuit frequency band range corresponding to the RF transceiver circuit and the antenna frequency band range corresponding to the antenna.

[0082] Optionally, a radio frequency transceiver circuit corresponding to a circuit frequency band range in which the frequency band is located may be used as the target transceiver component.

[0083] For example, when the antenna receives a signal sent by a base station, the antenna that receives the RF signal can be used as the target antenna, and then the target RF transceiver circuit can be determined from multiple RF transceiver circuits based on the circuit frequency band range corresponding to the RF transceiver circuit and the frequency band of the RF signal.

[0084] Optionally, an antenna corresponding to the antenna frequency band range in which the frequency band is located is used as the target transceiver component.

[0085] For example, when the RF transceiver circuit sends a signal to the antenna, the RF transceiver circuit that sends the RF signal can be used as the target RF transceiver circuit, and then the target antenna can be determined from multiple antennas based on the antenna frequency band range corresponding to the antenna and the frequency band of the RF signal.

[0086] In step S13, a target switch component to which the target transceiver component is connected is determined from the multiple switch components according to the frequency band and the switch frequency band range.

[0087] In some embodiments, the switch components corresponding to the switch frequency band range in which the frequency band is located may be firstly used as the switch components to be determined, and then the target may be determined from the switch components to be determined.

[0088] In step S14, the radio frequency signal is transmitted through a target path between the target transceiver component and the target switch component.

[0089] The above technical solution is adopted to obtain the frequency band corresponding to the radio frequency signal to be transmitted; determine the target transceiver component from multiple transceiver components according to the frequency band and the transceiver frequency band range; determine the target switch component connected to the target transceiver component from the multiple switch components according to the frequency band and the switch frequency band range; and transmit the radio frequency signal through the target path between the target transceiver component and the target switch component. In this way, the corresponding transmission path can be matched and flexibly adjusted according to the frequency band range supported by the transceiver component and the frequency band of the transmitted radio frequency signal through the connected multiple switch components, which can reduce the resource loss of the communication system, reduce the difficulty of antenna debugging, and improve signal transmission performance.
