Description

Technical Field

[0001] This application belongs to the field of communication technology, specifically relating to a radio frequency architecture and electronic device. Background Technology

[0002] Currently, 5G connectivity globally is divided into two types: Standalone (SA) and Non-Standalone (NSA). SA operates solely on the 5G frequency band (or New Radio (NR) band), while NSA uses both the 4G frequency band (or Long Term Evolution (LTE) band) and the 5G frequency band (or NR band). The 4G band handles control signals, while the 5G band handles data signals. The demand for NSA connectivity is widespread in most parts of the world. To ensure that electronic devices used in most parts of the world support NSA, the RF architecture must be able to support TRX signals in both the LTE and NR bands simultaneously. However, current RF architectures that support NSA typically use complex coexistence circuits and multiple independent antennas for LTE and NR to ensure that TRX signals in both bands work at the same time. This results in an increase in the number of antennas and high system complexity. Furthermore, current RF architectures that support NSA cannot meet the requirement of universal applicability in many parts of the world. Summary of the Invention

[0003] The purpose of this application is to provide a radio frequency architecture and electronic device that can solve the problems of the large number of antennas and high system complexity of current radio frequency architectures that support NSA, and also cannot meet the requirements of universal applicability in many regions around the world.

[0004] In a first aspect, embodiments of this application provide a radio frequency architecture, including: a main module, a diversity module, a first power amplifier module, a second power amplifier module, and an antenna module;

[0005] The diversity module is connected to the antenna module and is used to receive signals of the first communication standard and the second communication standard.

[0006] The first power amplifier module is connected to the antenna module through the main module, and is used to transmit and receive signals of one of the first and second communication standards.

[0007] The second power amplifier module is connected to the antenna module through a first path for transmitting and receiving signals of another communication standard among the first and second communication standards; or, the second power amplifier module is connected to the antenna module through the first and second paths respectively for transmitting and receiving signals of the first and second communication standards.

[0008] The first path is a path that does not pass through the main module, and the second path is a path that passes through the main module.

[0009] Secondly, embodiments of this application provide an electronic device including the radio frequency architecture described above.

[0010] In this embodiment, by connecting the diversity module to the antenna module, signal reception for both the first and second communication standards is achieved. Furthermore, by connecting the first power amplifier module to the antenna module via the main module, signal transmission and reception for one of the first and second communication standards is achieved. Alternatively, the second power amplifier module can be connected to the antenna module via a first path that bypasses the main module to achieve signal transmission and reception for the other of the first and second communication standards. Or, the second power amplifier module can be connected to the antenna module via both the first path and a second path that passes through the main module to achieve signal transmission and reception for both the first and second communication standards. This design allows for the sharing of the antenna module for signal transmission and reception under both communication standards, ensuring that the RF architecture supports NSA while avoiding an increase in the number of antennas and reducing system complexity. Moreover, the RF architecture in this embodiment can meet the needs of different frequency bands in different regions globally, solving the problem that current RF architectures cannot meet the universal applicability requirements of multiple regions worldwide.

[0017] The first power amplifier module 3 is connected to the antenna module 5 through the main module 1, and is used to transmit and receive signals of one of the first and second communication standards.

[0018] The second power amplifier module 4 is connected to the antenna module 5 through a first path, and is used to transmit and receive signals of another communication standard among the first and second communication standards; or, the second power amplifier module 4 is connected to the antenna module 5 through the first path and the second path respectively, and is used to transmit and receive signals of the first and second communication standards.

[0019] The first path is a path that does not pass through the main module 1, and the second path is a path that passes through the main module 1.

[0020] Optionally, the master module 1 refers to a signal path that can support both transmission and reception, while the diversity module 2 refers to a signal path that can only support reception.

[0021] Specifically, as one implementation: the diversity module 2 is connected to the antenna module 5 to receive signals of the first communication standard and the second communication standard; the first power amplifier module 3 is connected to the antenna module 5 through the main module 1 to transmit and receive signals of one of the first and second communication standards; the second power amplifier module 4 is connected to the antenna module 5 through a first path to transmit and receive signals of the other of the first and second communication standards (that is, the second power amplifier module 4 is not connected to the antenna module 5 through the main module 1).

[0022] In this embodiment, for example, if the first power amplifier module 3 and the antenna module 5 are connected via the main module 1 to transmit and receive signals under the first communication standard, then the second power amplifier module 4 and the antenna module 5 are connected without passing through the main module 1 and are used to transmit and receive signals under the second communication standard. Alternatively, for example, if the first power amplifier module 3 and the antenna module 5 are connected via the main module 1 to transmit and receive signals under the second communication standard, then the second power amplifier module 4 and the antenna module 5 are connected without passing through the main module 1 and are used to transmit and receive signals under the first communication standard.

[0023] Specifically, as another implementation: the diversity module 2 is connected to the antenna module 5 to receive signals of the first communication standard and the second communication standard; the first power amplifier module 3 is connected to the antenna module 5 through the main module 1 to transmit and receive signals under the first communication standard; the second power amplifier module 4 is connected to the antenna module 5 through the first path and the second path respectively to transmit and receive signals of the first communication standard and the second communication standard (that is, at least one port of the second power amplifier module 4 can be connected to the antenna module 5 without going through the main module 1, and at least one other port of the second power amplifier module 4 can also be connected to the antenna module 5 through the main module 1).

[0024] In this embodiment, for example, the path connecting the first power amplifier module 3 and the antenna module 5 via the main module 1, and the path connecting the second power amplifier module 4 and the antenna module 5 via the main module 1, can both be used to transmit and receive signals under the first communication standard; the path connecting the second power amplifier module 4 and the antenna module 5 without passing through the main module 1 is used to transmit and receive signals under the second communication standard. Optionally, when the second power amplifier module 4 and the antenna module 5 are connected via the main module 1 and there are multiple paths, all paths connecting the second power amplifier module 4 and the antenna module 5 via the main module 1 can be used to transmit and receive signals under the first communication standard; or, a portion of the paths connecting the second power amplifier module 4 and the antenna module 5 via the main module 1 can be used to transmit and receive signals under the first communication standard, and another portion of the paths connecting the second power amplifier module 4 and the antenna module 5 via the main module 1 can also be used to transmit and receive signals under the second communication standard, etc., and this embodiment is not limited thereto.

[0025] The radio frequency (RF) architecture in this embodiment connects diversity module 2 to antenna module 5 to receive signals for both the first and second communication standards. It also connects first power amplifier module 3 to antenna module 5 via main module 1 to transmit and receive signals for one of the first and second communication standards. Furthermore, it connects second power amplifier module 4 to antenna module 5 via a first path that does not pass through main module 1 to transmit and receive signals for the other of the first and second communication standards. Alternatively, second power amplifier module 4 can be connected to antenna module 5 via both the first path and a second path that passes through main module 1 to transmit and receive signals for both the first and second communication standards. This design allows signal transmission and reception for both the first and second communication standards to share antenna module 5, ensuring that the RF architecture supports NSA while avoiding an increase in the number of antennas and reducing system complexity. Moreover, the RF architecture in this embodiment can meet the needs of different frequency bands in different regions globally, solving the problem that current RF architectures cannot meet the universal applicability requirements of multiple regions worldwide.

[0026] Optionally, please continue to see Figure 1 When the second power amplifier module 4 is connected to the antenna module 5 through the first path, the radio frequency architecture further includes: a first switch 6.

[0027] The diversity module 2 is connected to the antenna module 5 via the first switch 6, and the first power amplifier module 3 is connected to the antenna module 5 via the main module 1 and the first switch 6.

[0028] When the second power amplifier module 4 is connected to the antenna module 5 through the first path, the first path includes the first switch 6.

[0029] The first switch 6 is used to switch at least one of the diversity module 2, the first power amplifier module 3 and the second power amplifier module 4 to be connected to the antenna module 5.

[0030] For example, the antenna module 5 can be equipped with multiple antenna units. The first switch 6 can be used to switch the diversity module 2, the first power amplifier module 3 and the second power amplifier module 4 to be connected to different antenna units respectively, or the first switch 6 can be used to switch at least two of the diversity module 2, the first power amplifier module 3 and the second power amplifier module 4 to time-division multiplex the antenna units in the antenna module 5.

[0031] Specifically, the antenna module 5 includes: a first antenna unit 51, a second antenna unit 52, and a third antenna unit 53; the first switch 6 has multiple conduction states; wherein, the multiple conduction states include at least one of the following:

[0032] In the first conduction state, the diversity module 2 is connected to the first antenna unit 51;

[0033] In the second conduction state, the first power amplifier module 3 is connected to the second antenna unit 52 through the main module 1;

[0034] In the third conduction state, the second power amplifier module 4 is connected to the third antenna unit 53 through the first path.

[0035] Optionally, the first switch 6 can switch between the aforementioned multiple conduction states (i.e., switch between the first conduction state, the second conduction state, and the third conduction state). Alternatively, the first switch 6 can switch between multiple conduction states, or it can be in at least two conduction states simultaneously (e.g., simultaneously in the first and second conduction states, or simultaneously in the second and third conduction states, or simultaneously in the first, second, and third conduction states, etc.). This application embodiment is not limited to these limitations. For example, the first switch 6 can be a three-pole three-throw switch, or other switch combinations (e.g., using two double-pole double-throw switches), etc., to enable the radio frequency architecture to support NSA. This application embodiment is not limited to these limitations.

[0037] Optionally, the second power amplifier module 4 can also be connected to the antenna module 5 through a first signal processing unit 11 (for example, the first signal processing unit 11 may include a duplexer and / or a filter, etc.). Alternatively, the second power amplifier module 4 can also be connected to the antenna module 5 through multiple first signal processing units 11 (for example, the first signal processing unit 11 may include a duplexer and / or a filter, etc.) to achieve multi-band coverage under the second communication standard, etc. (For example, when the second power amplifier module 4 is connected to the antenna module 5 through multiple first signal processing units 11, a switch can also be set between the multiple first signal processing units 11 and the antenna module 5 to switch the path of different frequency bands of the second power amplifier module 4 connected to the antenna module 5, etc.). The embodiments of this application are not limited thereto.

[0038] It should be noted that the filters and / or duplexers in the embodiments of this application may be selected and designed according to the usage region of the electronic equipment to which the RF architecture is applied, and no specific limitation is made in the embodiments of this application.

[0039] For example, the first communication standard is LTE, and the second communication standard is NR. In practical applications, if this RF architecture is used in electronic devices in the first region, and the first power amplifier module 3 is an NR power amplifier module and the second power amplifier module 4 is an LTE power amplifier module, then the first power amplifier module 3 is connected to the antenna module 5 through the main module 1 to achieve NR band signal transmission and reception; the second power amplifier module 4 is not connected to the antenna module 5 through the main module 1 to achieve LTE band signal transmission and reception. If this RF architecture is used in electronic devices in the second region, and the first power amplifier module 3 is an LTE power amplifier module and the second power amplifier module 4 is an NR power amplifier module, then the first power amplifier module 3 is connected to the antenna module 5 through the main module 1 to achieve LTE band signal transmission and reception; the second power amplifier module 4 is not connected to the antenna module 5 through the main module 1 to achieve NR band signal transmission and reception.

[0040] Optionally, for diversity module 2, in practical applications, if the radio frequency architecture is used in electronic devices in the first region, the signal path in diversity module 2 can use a two-port switch; or, if the radio frequency architecture is used in electronic devices in the second region, the signal path in diversity module 2 can be a single-port switch, etc. The embodiments of this application are not limited thereto.

[0041] This embodiment employs a radio frequency architecture that, by adjusting the selection of components, can meet the different frequency band requirements in different regions around the world and achieve NSA support, thus possessing universal applicability.

[0042] Optionally, please continue to see Figure 2 When the second power amplifier module 4 is connected to the antenna module 5 through the first path and the second path respectively, the second path includes the first sub-path, and the radio frequency architecture also includes: the second switch 7.

[0043] The first power amplifier module 3 is connected to the antenna module 5 via the second switch 7, the main module 1, and the first port of the second power amplifier module 4 is connected to the antenna module 5 via the first sub-path, and the first sub-path includes the second switch 7.

[0044] The second switch 7 is used to switch at least one of the first power amplifier module 3 and the second power amplifier module 4 to be connected to the main unit module 1; wherein, the path between the first power amplifier module 3 and the antenna module 5, and the path between the first port of the second power amplifier module 4 and the antenna module, are both used to transmit and receive signals under the first communication standard.

[0045] For example, the second switch 7 has multiple on states. Specifically, the multiple on states include at least one of the following:

[0046] In the first conduction state, the first power amplifier module 3 is connected to the main assembly module 1;

[0047] In the second conduction state, the second power amplifier module 4 is connected to the main unit module 1.

[0048] Optionally, the second switch 7 can switch between the above-mentioned multiple conduction states (that is, switch between the first conduction state and the second conduction state). Alternatively, the second switch 7 can switch between multiple conduction states, or it can be in multiple conduction states simultaneously (such as being in the first conduction state and the second conduction state simultaneously), etc., and the embodiments of this application are not limited thereto.

[0049] In this embodiment, by setting a path between the first power amplifier module 3 and the antenna module 5, and a path between the first port of the second power amplifier module 4 and the antenna module, both are used to transmit and receive signals under the first communication standard, which can meet the different frequency band requirements of NSA support in different regions.

[0050] For example, if the first communication standard is LTE, the first power amplifier module 3 can be an LTE power amplifier module, and the second power amplifier module can be an NR power amplifier module. In practical applications, if this RF architecture is used in electronic devices in a second region, the first power amplifier module 3 can achieve signal transmission and reception under the LTE communication standard through the path between the main module 1 and the antenna module 5. If this RF architecture is used in electronic devices in a first region, the second power amplifier module 4 can achieve signal transmission and reception under the LTE communication standard through the path between the main module 1 and the antenna module 5. In this way, this RF architecture can meet the different frequency band requirements of different regions around the world and support NSA. Furthermore, it can reduce the selection of adjustment devices for different frequency band requirements that support NSA in different regions, thus having higher universal applicability.

[0051] Optionally, the second switch 7 can also be connected to the main module 1 via a filter or the like. Alternatively, the first power amplifier module 3 can also be connected to the main module 1 via one or more filters to achieve coverage of multiple frequency bands under the first communication standard. Optionally, the signal path in the main module 1 can use a single-port switching switch or the like, and this embodiment is not limited thereto.

[0054] The path between the second port of the second power amplifier module 4 and the antenna module 5, and the path between the third port of the second power amplifier module 4 and the antenna module 5, are both used to transmit and receive signals under the second communication standard.

[0055] For example, the second communication standard is the NR communication standard, and the second power amplifier module 4 can be an NR power amplifier module. In practical applications, if this RF architecture is used in electronic devices in a second region, the signal transmission and reception under the NR communication standard can be achieved by using a path between the second power amplifier module 4 and the antenna module 5 without passing through the main module 1. If this RF architecture is used in electronic devices in a first region, the signal transmission and reception under the NR communication standard can be achieved by using a path between the second power amplifier module 4 and the antenna module 5 through the main module 1. In this way, this RF architecture can meet the different frequency band requirements of different regions around the world and support NSA, and can reduce the selection of adjustment devices for different frequency band requirements that support NSA in different regions, thus having higher universal applicability.

[0056] Optionally, the RF architecture further includes a third switch 8; the second port of the second power amplifier module 4 is connected to the antenna module 5 through the first path, and the first path includes the third switch 8.

[0057] Specifically, the antenna module 5 includes a fourth antenna unit 54 and a fifth antenna unit 55; the second port of the second power amplifier module 4 is connected to the fourth antenna unit 54 and the fifth antenna unit 55 respectively through the first path, and the first path includes the third switch 8. The third switch 8 is used to switch the second port of the second power amplifier module 4 to be connected to one of the fourth antenna unit 54 and the fifth antenna unit 55.

[0058] For example, the third switch 8 has multiple on states. These multiple on states include at least one of the following:

[0059] In the first conduction state, the second port of the second power amplifier module 4 is connected to the fourth antenna unit 54;

[0060] In the second conduction state, the second port of the second power amplifier module 4 is connected to the fifth antenna unit 55.

[0061] Optionally, the third switch 8 can switch between the above-mentioned multiple conduction states (that is, switch between the first conduction state and the second conduction state). Alternatively, the third switch 8 can switch between multiple conduction states, or it can be in multiple conduction states simultaneously (such as being in the first conduction state and the second conduction state simultaneously), etc., and the embodiments of this application are not limited thereto.

[0062] In this embodiment, by switching the second port of the second power amplifier module 4 to one of the fourth antenna unit 54 and the fifth antenna unit 55 through the third switch 8, multi-band coverage under the NR communication standard or polling transmission and reception functions can be further realized. This embodiment is not limited to this.

[0063] Optionally, the second port of the second power amplifier module 4 can also be connected to the third switch 8 through the second signal processing unit 12 (for example, the second signal processing unit 12 may include a filter and / or a duplexer, etc.). The specific design can be selected based on the specific NR frequency band covered, etc., and the embodiments of this application are not limited thereto.

[0064] Optionally, the radio frequency architecture further includes a fourth switch 9, and the second sub-path includes the fourth switch 9.

[0065] The third port of the second power amplifier module 4 is also connected to the antenna module 5 via a third path (i.e.) Figure 2 (Q) in the middle jumper, wherein the third path is a path that does not pass through the main set module 1.

[0066] The fourth switch 9 is used to switch whether the third port of the second power amplifier module 4 is connected to the antenna module 5 through the main module 1 or not.

[0067] For example, the fourth switch 9 has multiple on states, and can be switched between these multiple on states. The multiple on states include:

[0068] In the first conducting state, the third port of the second power amplifier module 4 is connected to the antenna module 5 through the main assembly module 1;

[0069] In the second conduction state, the third port of the second power amplifier module 4 is not connected to the antenna module 5 through the main module 1.

[0070] Specifically, the third port of the second power amplifier module 4 is connected to the fourth antenna unit 54 through the third path, and the fourth switch 9 is used to switch the third port of the second power amplifier module 4 to be connected to one of the main module 1 and the fourth antenna unit 54.

[0071] In this embodiment, the jumper Q is designed using the fourth switch 9, providing multiple design options when the RF architecture is used in electronic devices in the first region. Furthermore, by switching the third port of the second power amplifier module 4 with one of the main module 1 and the fourth antenna unit 54 via the fourth switch 9, multi-band coverage under the NR communication standard, or polling and transceiver functions, can be further realized. This embodiment is not limited to these limitations.

[0072] Optionally, the third port of the second power amplifier module 4 can also be connected to the fourth switch 9 through the third signal processing unit 13 (such as the third signal processing unit 13 including filters and / or duplexers, etc.). The specific design can be selected based on the specific NR frequency band covered, etc., and the embodiments of this application are not limited thereto.

[0074] For example, the fifth switch 10 has multiple on states. These multiple on states include at least one of the following:

[0075] In the first conduction state, the diversity module 2 is connected to the antenna module 5;

[0076] In the second conduction state, the main module 1 and the antenna module 5 are connected.

[0077] For example, multiple antenna units can be set in the antenna module 5, and the fifth switch 10 can be used to switch the diversity module 2 and the main module 1 to be connected to different antenna units respectively.

[0078] Specifically, the antenna module 5 includes a sixth antenna unit 56 and a seventh antenna unit 57; the fifth switch 10 has multiple conduction states; wherein, in the first conduction state, the diversity module 2 is connected to the sixth antenna unit 56; and in the second conduction state, the main module 1 is connected to the seventh antenna unit 57.
