[0033] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0034] It is understood that the terms "first," "second," etc., used herein may be used to describe various elements, but these elements are not limited by these terms. These terms are only used to distinguish one element from another and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0035] The radio frequency devices and systems involved in this application can be applied to electronic devices with wireless communication capabilities. These electronic devices can be handheld devices, in-vehicle devices, smart cars, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE) (e.g., mobile phones), mobile stations (MS), etc. For ease of description, the devices mentioned above are collectively referred to as electronic devices. The electronic device in this embodiment can support communication with other electronic devices, and can also support communication with a communication server, such as a base station router or other connection site; the electronic device can also support communication with other electronic devices.

[0036] Figure 1 This is one of the structural block diagrams of a radio frequency system according to an embodiment, with reference to... Figure 1 In this embodiment, the radio frequency system includes: a first radio frequency transceiver 10, a second radio frequency transceiver 20, and a first radio frequency device 30.

[0037] The first radio frequency device 30 is connected to the first radio frequency transceiver 10, the second radio frequency transceiver 20, and the first antenna ANT1, respectively, and is used to receive and process the communication signal received by the first antenna ANT1, and transmit the processed communication signal to either the first radio frequency transceiver 10 or the second radio frequency transceiver 20.

[0038] The communication signals include a first frequency band signal and a second frequency band signal with different communication standards. The first frequency band signal is a short-range wireless signal, and both the first and second frequency bands are within a preset frequency range. The first and second frequency bands being within the preset frequency range can be understood as the first and second frequency bands being in adjacent frequency ranges. Adjacent frequency ranges can include at least one of two frequency bands separated by a certain distance or two frequency bands that at least partially overlap within the preset frequency range. Furthermore, two frequency bands that are nearly completely overlapping or completely overlap can be understood as being on the same frequency.

[0039] The first frequency band signal is a short-range wireless signal, and the second frequency band signal is a non-short-range wireless signal. For example, the short-range wireless signal can include either Wi-Fi or Bluetooth (BT). The Wi-Fi signal can include either 2.4GHz Wi-Fi or 5GHz Wi-Fi, and the Bluetooth signal can include either 2.4GHz BT or 5GHz BT. It is understood that this application embodiment is not limited to the aforementioned Wi-Fi and BT signals, and this embodiment will not describe them in detail. The first frequency band signal can be any of 2.4GHz BT, 5GHz BT, 2.4GHz Wi-Fi, or 5GHz Wi-Fi. For example, the second frequency band signal can be a cellular signal within a preset frequency range. For instance, when the first frequency band signal is a 2.4GHz Wi-Fi / BT signal, the second frequency band signal can be a B / N41 band signal; for instance, when the first frequency band signal is a 5GHz Wi-Fi / BT signal, the second frequency band signal can be an N79 band signal.

[0040] The first radio frequency device 30 supports receiving and processing signals from a first frequency band and a second frequency band. This receiving and processing may include low-noise amplification and filtering. For example, when the first antenna ANT1 simultaneously receives signals from both the first and second frequency bands, the first radio frequency device 30 can simultaneously support low-noise amplification and filtering of both signals to obtain the processed signals. The filtering process can remove other frequency band signals or noise signals besides the first and second frequency band signals. It is understood that when the first antenna ANT1 receives only one of the first and second frequency band signals, the first radio frequency device 30 can also perform receiving and processing on either the received first or second frequency band signal.

[0041] The first radio frequency device 30 can be understood as a packaged integrated device that can support the reception and processing of signals in the first frequency band and the second frequency band, respectively. For example, taking WIFI and cellular standards as examples, the first radio frequency device 30 can be understood as a front-end integrated device for WIFI and cellular standards, such as an LPAF device or a FEM (Front-end Module); for example, the first radio frequency device 30 can also be understood as a WIFI FEM supporting cellular standards, or an LPAF device supporting WIFI standards. It is understood that the first radio frequency device 30 can also be other types of packaged devices, which will not be described in detail here.

[0042] The first RF transceiver 10 is used to obtain a first frequency band signal from the received communication signal; the second RF transceiver 20 is used to obtain a second frequency band signal from the received communication signal. For example, the first RF transceiver 10 and the second RF transceiver 20 are respectively configured to support the identification and filtering of signals of the corresponding target standard, so that the filtered signals can enter other processing stages. Other processing stages may include modulation and demodulation of the filtered signals to obtain the communication data carried by the signals; before modulation and demodulation, other processing stages may also include frequency conversion processing of the filtered signals to facilitate signal parsing. Exemplarily, after the first RF transceiver 10 and the second RF transceiver 20 perform signal parsing, they can transmit the parsed signals to the application processor (AP) respectively, and the AP obtains the corresponding communication instructions based on the parsed signals.

[0043] When the first radio frequency transceiver 10 receives the processed communication signal, the first radio frequency transceiver 10 supports identifying and filtering the first frequency band signal of the wireless short-range standard from the communication signal, for example, it can identify and filter the 5G WIFI frequency band signal; when the second radio frequency transceiver 20 receives the processed communication signal, the second radio frequency transceiver supports identifying and filtering the second frequency band signal of the non-wireless short-range standard from the communication signal, for example, it can identify and filter the N79 frequency band signal.

[0044] In related technologies, taking WIFI and cellular standards as examples, the WIFI receiving system and the cellular receiving system are two independent systems. Each system corresponds to an independent radio frequency transceiver and radio frequency receiving circuit. When the WIFI system needs to achieve high-order diversity, the hardware cost of multiple receiving circuits cannot meet the needs of electronic devices.

[0045] The radio frequency system provided in this embodiment includes a first radio frequency transceiver 10, a second radio frequency transceiver 20, and a first radio frequency device 30. The first radio frequency device 30 can support the reception and processing of communication signals, including first band signals and second band signals of different communication standards but all within the same preset frequency range, and the first band signal is a short-range wireless signal. Therefore, the first radio frequency device 30 can support both short-range wireless and non-short-range wireless standards, and can be reused as a receiving device for two different communication standard receiving systems, reducing the number of devices and lowering hardware costs. In applications where the radio frequency system needs to support multi-level diversity of the first band signal and / or the second band signal, it can still meet the needs of electronic devices.

[0046] In one embodiment, such as Figure 2 As shown, the radio frequency system also includes: radio frequency module 40 and aggregation module 50.

[0047] The radio frequency (RF) module 40, connected to the second antenna ANT2, is used to receive and process the first frequency band signal received by the second antenna ANT2. The RF module 40 and the first RF device 30 can each support the reception and processing of the first frequency band signal. Through the combination of the RF module 40 and the first RF device 30, multi-level diversity of the first frequency band signal can be achieved. The reception and processing can be referred to the above embodiment, and will not be repeated here. The RF module 40 and the first RF device 30 can be understood as RF front-end devices in the RF system.

[0048] For example, a combination of a radio frequency module 40 and a first radio frequency device 30 can realize the main diversity reception of the first frequency band signal and the reception of at least one channel of the second frequency band signal; when there are multiple radio frequency modules 40 and the first radio frequency device 30, the high-order diversity reception of the first frequency band signal and the reception of at least one channel of the second frequency band signal can be realized.

[0049] For example, the RF module 40 may include several discrete devices or be integrated into a packaged device. For example, when the RF module 40 is packaged into an integrated device, the RF module 40 can be understood as a FEM device. Furthermore, taking the WIFI standard as an example, the RF device can be a WIFI FEM, that is, a front-end integrated module for WIFI.

[0050] The aggregation module 50 is used to aggregate the communication signals received and processed by the first radio frequency device 30 and the first frequency band signals received and processed by the radio frequency module 40, and transmit them to the receiving channel of the first radio frequency transceiver 10. Through simple signal aggregation, the aggregation module 50 enables the same receiving channel to receive multiple first frequency band signals from the first radio frequency device 30 and the radio frequency module 40, improving the receiving performance of the receiving channel. It is also low-cost and can be applied on a large scale.

[0051] For example, the number of ports of the aggregation module 50 can be set based on the actual application requirements of the radio frequency system to match the number of first frequency band signals processed by aggregation and the degree of performance enhancement to the receiving channel. For instance, when the aggregation module 50 needs to aggregate the first frequency band signals received by four antennas for transmission to a receiving channel, the number of ports is set to four, to be connected to the first radio frequency device 30 and the radio frequency module 40 respectively. When the aggregation module 50 needs to aggregate the communication signals received by two antennas, the number of ports is set to two, to be connected to the first radio frequency device 30 and the radio frequency module 40 respectively.

[0052] It is understood that the number of ports of the aggregation module 50 is consistent with the total number of the corresponding connected first RF devices 30 and RF modules 40. It is understood that, given the reception performance of the receiving channel, the more aggregated signals received by a single receiving channel, the greater the enhancement in reception performance. It is understood that, in other embodiments, the number of aggregation modules 50 can be set based on the actual application requirements of the RF system to match the number of different receiving channels.

[0053] In related technologies, on the one hand, the higher the order of diversity reception, the more RF front-end devices and receiving channels are required. Furthermore, when multi-order diversity reception needs to support two different signal standards, the number of RF circuits is even greater, making it difficult for the RF system to meet low-cost hardware requirements and hindering the miniaturization of the RF system. On the other hand, in RF systems supporting short-range standards, different channel groups receive signals at different frequency bands. Receiving channels within the same channel group cannot support high-order diversity reception. Moreover, when multiple channel groups are used to achieve high-order diversity reception, the performance improvement required when the RF system is connected to a single communication server cannot be met.

[0054] Taking WIFI and cellular systems as examples, although WIFI and cellular systems share the same AP, their internal radio frequency transceivers and radio frequency front-end devices are independent, and the entire radio frequency system involves a large number of radio frequency front-end devices.

[0055] And, as Figure 3 As shown, the radio frequency transceiver of a WIFI system in related technologies typically includes a first radio frequency channel group and a second radio frequency channel group. Each radio frequency channel group includes several receiving channels, and each receiving channel is connected to a radio frequency front-end device. The first radio frequency channel group can support one WIFI frequency band signal, which can be understood as the first channel group communicating with a communication server, such as a router. The second radio frequency channel group can support another WIFI frequency band signal, which can be understood as the second radio frequency channel group communicating with another communication server, such as another router. However, in practical applications, on the one hand, the setup of two channel groups cannot meet the performance improvement requirements when the radio frequency system communicates with a single router; on the other hand, the probability of the radio frequency system communicating with two different frequency bands of WIFI signals simultaneously is low. Currently, users usually mainly use routers that support one WIFI frequency band in actual use. For example, if a user's living environment happens to use only a 5G WIFI band router to achieve communication with the radio frequency system, the probability of the user simultaneously experiencing multi-band scenarios of 5G WIFI and 2.4G WIFI is low, resulting in a waste of resources for the 2.4G WIFI channel group.

[0056] In this embodiment, on the one hand, since the first RF device 30 supports reception processing of two different standards, it can be connected to the first RF transceiver 10 and the second RF transceiver 20 respectively. The first RF transceiver 10 obtains the first frequency band signal from the received communication signal, and the second RF transceiver 20 obtains the second frequency band signal from the received communication signal. Thus, when the RF system needs to support high-order diversity of the first frequency band signal and reception processing of the second frequency band signal, the first RF device 30 realizes multiplexing of reception processing of different frequency band signals, reduces the number of RF modules 40, and lowers costs.

[0057] On the other hand, by aggregating the first frequency band signals received and processed by the first RF device 30 and RF module 40 through the aggregation module 50 and transmitting them to the receiving channel of the first RF transceiver 10, the previously independent reception of the first RF device 30 and RF module 40 is converted into cooperative signal reception. This can enhance the signal coverage and penetration of each receiving channel, as well as the reception rate, reception strength, and throughput of each receiving channel, thereby improving the reception performance of each receiving channel and thus achieving performance improvement when communicating with a single communication server. In addition, by improving the performance of the receiving channel and aggregating multiple signals, the dependence on more receiving channels can be reduced, thereby reducing the number of RF channel groups and further reducing hardware costs, which is conducive to the miniaturization and low-cost design of the RF transceiver.

[0058] Taking Wi-Fi as an example, Wi-Fi signals are easily attenuated by obstacles such as walls and furniture in indoor environments, resulting in significant penetration loss. By aggregating multiple Wi-Fi signals of the same frequency band to a receiving channel, signal power can be superimposed and energy concentrated, enhancing the signal coverage and penetration capability of a single receiving channel and improving the reception stability of Wi-Fi signals in complex indoor environments. By aggregating multiple Wi-Fi signals, the receiving performance of the receiving channel, such as reception rate, reception strength, and data throughput, can be improved, which is beneficial to the high-bandwidth application requirements of electronic devices such as video streaming and VR. In addition, by aggregating multiple Wi-Fi signals, the performance of a single channel can be improved without relying on more receiving channels, reducing the number of receiving channels and thus the number of RF channel groups, thereby reducing hardware costs.

[0059] In one embodiment, the aggregation module 50 may be a hardware circuit with signal aggregation function to implement a simple signal aggregation function; the aggregation module 50 may also be a software circuit or a hardware-software hybrid circuit with a signal aggregation processing algorithm.

[0060] Taking the aggregation module 50 as an example of hardware circuit, the aggregation module 50 may include a power divider. The first end of the power divider is connected to the receiving channel, at least one second end of the power divider is connected to the first RF device 30, and at least another second end of the power divider is connected to the RF module 40. The power divider is used to support the distribution of one RF signal to be transmitted to multiple output ports according to a preset energy ratio, or to reversely aggregate the energy of multiple received signals to one output. This embodiment mainly utilizes the reverse aggregation function of the power divider. The power divider has low hardware cost. Due to its reverse aggregation function, the RF system does not require additional customization of the power divider during application. Furthermore, the power divider has a standardized interface and universal RF impedance design specifically for RF, which can be directly adapted to the connection with the first RF device 30 and the RF module 40 without redesigning the first RF device 30 and the RF module 40. Therefore, by using the power divider, the large-scale application of the RF system can be expanded based on the implementation of signal aggregation function.

[0061] For example, the aggregation circuit can be selected from two-way power dividers, three-way power dividers, four-way power dividers, etc., depending on the actual application. For example, when the aggregation module 50 needs to aggregate the first frequency band signals transmitted through three receiving paths, the aggregation module 50 may include one two-way power divider; for example, when the aggregation module 50 needs to aggregate the first frequency band signals transmitted through three or more receiving paths, the aggregation module 50 may include multiple two-way power dividers, and the aggregation of multiple signals can be achieved by combining multiple two-way power dividers.

[0062] For example, such as Figure 4 As shown, when the aggregation module 50 needs to aggregate the communication signals received by a first radio frequency device 30 and three radio frequency modules 40, the aggregation module 50 may include three power dividers, wherein two power dividers aggregate two input signals into two intermediate signals respectively, and the third power divider further aggregates the two intermediate signals output from the first two stages into one final output, thereby realizing the superposition of four signals.

[0063] Compared to multi-port models such as three-port and four-port power dividers, dual-port power dividers have a simpler structure, lower cost, less loss, and higher efficiency. At the same time, they are highly adaptable and can be easily integrated into the first RF device 30, the first RF transceiver 10, or the RF module 40.

[0064] In other embodiments, the aggregation module 50 may also include other hardware circuits such as a frequency combiner and a power combiner, which will not be described in detail in this embodiment.

[0065] It is understood that the aggregation module 50 in any of the above embodiments can be disposed outside the first RF transceiver 10, the first RF device 30, and the RF module 40, or it can be integrated inside any of the first RF transceiver 10 and the first RF device 30, or it can be packaged with the RF module 40 as a second RF device, in order to improve the integration of any one of the first RF transceiver 10, the first RF device 30, and the RF module 40 and expand the aggregation function of any of these devices, thereby simplifying the peripheral structure while achieving performance improvement. The following are some optional examples for further explanation:

[0066] In one embodiment, such as Figure 5 As shown, the aggregation module 50 is integrated inside the first radio frequency device 30 (for ease of illustration, the first radio frequency device with the aggregation module 50 integrated is still referred to as 30 in the figure).

[0067] The first RF device 30 is configured with a first input port (Rxi1 in the figure), a first output port (Rx1 in the figure), a second output port (Rx2 in the figure), and a first antenna port (Ant1 in the figure) connected to the first antenna ANT1. The first RF device 30 can be understood as a packaged device, and the first input port, the first antenna port, the first output port, and the second output port can be understood as RF pin terminals of the packaged device, used to connect to the RF module 40, the antenna, the first RF transceiver 10, and the second RF transceiver 20.

[0068] The system comprises a first antenna port connected to the first antenna ANT1, a first output port connected to the receiving channels of the aggregation module 50 and the first RF transceiver 10, a second output port connected to the second RF transceiver 20, and a first input port connected to the aggregation module 50 and the RF module 40. Communication signals received by the first antenna ANT1 are transmitted to the first RF device 30 via the first antenna port. First frequency band signals received by the RF module 40 are transmitted to the first RF device 30 via the first input port. The first frequency band signals processed by the first RF device 30 are transmitted to the first RF transceiver 10 via the first output port or to the second RF transceiver 20 via the second output port.

[0069] The first radio frequency device 30 includes an aggregation module 50, and further includes a first receiving module 310 and a first gating module 320. The first receiving module 310 is connected to the first antenna port and is used to receive and process the communication signals transmitted through the first antenna port. The first gating module 320 is connected to the first receiving module 310, the aggregation module 50, and the second output port, respectively, and is used to connect the first receiving module 310 to any one of the aggregation module 50 and the second output port.

[0070] The first receiving module 310 is used to receive and process the communication signals received at the first antenna port. The relevant description of the receiving and processing can be found in the above embodiments and will not be repeated here. For example, the first receiving module 310 can support low-noise amplification processing of the received first frequency band signals and second frequency band signals; for example, the first receiving module 310 can also support filtering processing of the received first frequency band signals and second frequency band signals.

[0071] The first gating module 320 is used to transmit the communication signal received and processed by the first receiving module 310 to the aggregation module 50, so that the aggregation module 50 can aggregate the communication signal and the first frequency band signal from the radio frequency module 40, and transmit the aggregated signal to the first radio frequency transceiver 10 through the first output port; or transmit the communication signal received and processed by the first receiving module 310 to the second radio frequency transceiver 20 through the second output port, so as to realize the multiplexing of the first radio frequency device 30 in different communication system standards.

[0072] By connecting the aggregation module 50 integrated inside the first RF device 30 with the first gating module 320, the first input port, and the first output port, the aggregation module 50 can perform aggregation processing on the signals received and processed by the first RF device 30 and the RF module 40. On the one hand, the aggregation module 50 cooperates with the first RF device 30 and the RF module 40. By directly integrating the aggregation module 50 into the first RF device 30, the transmission path between the aggregation module 50 and the first gating module 320 can be shortened at least, while avoiding possible interference between the discrete aggregation module 50 and the RF module 40 at the connection point, thus reducing signal energy waste. On the other hand, integrating the aggregation module 50 inside the first RF device 30 can increase the integration level of the first RF device 30 and expand its aggregation function, simplifying the peripheral structure while improving performance.

[0073] For example, there are multiple first input ports, and each of the multiple first input ports is connected to a corresponding multiple radio frequency module 40. Thus, the first radio frequency device 30 can be connected to multiple radio frequency modules 40. The aggregation module 50 can receive the first frequency band signals processed by the multiple radio frequency modules 40 through the multiple first input ports, thereby realizing the aggregation of more first frequency band signals and thus achieving a greater improvement in the receiving performance of the receiving channel.

[0074] For example, such as Figure 6 As shown, the first receiving module 310 includes a filtering unit 311 and a low-noise amplification unit 312.

[0075] The filtering unit 311 is connected to the first antenna port and is used to support filtering of the first frequency band signal and the second frequency band signal; the low noise amplification unit 312 is connected to the filtering unit 311 and is used to amplify the filtered first frequency band signal and the second frequency band signal with low noise.

[0076] The filtering unit 311 is connected to the first antenna port and is used to filter the communication signal received by the first antenna ANT1. It can be understood that the filtering unit 311 can support filtering of signals in both the first and second frequency bands. The filtering unit 311 can be, for example, a surface acoustic wave (SAW) filter, which only allows communication signals in a preset frequency band to pass through, thereby eliminating spurious signals or harmonics in the main wave sideband. The filter can be a bandpass filter, a low-pass filter, etc.

[0077] The low-noise amplification unit 312 is connected to the aggregation module 50 and the filtering unit 311, respectively, and is used to perform low-noise amplification processing on the filtered communication signal. The low-noise amplification unit 312 may include one low-noise amplifier or two low-noise amplifiers to achieve two-stage low-noise amplification processing.

[0078] In this embodiment, the first receiving module 310 includes a filtering unit 311 and a low-noise amplification unit 312, which can respectively support the first frequency band signal and the second frequency band signal of two different communication standards within the same preset frequency range. Compared with multiple radio frequency devices or multiple discrete radio frequency modules 40, the first radio frequency device 30 can achieve higher utilization and the overall hardware cost of the radio frequency system is lower.

[0079] For example, the first receiving module 310 may further include a receiving bypass, connected to both ends of the low-noise amplification unit 312, for bypassing the low-noise amplification unit 312 and transmitting communication signals when the two ends of the low-noise amplification unit 312 are connected in the conductive state. The receiving bypass can linearly amplify the communication signal received by the first antenna ANT1 when it is relatively weak, while controlling the noise it introduces to an extremely low level, ensuring that the signal still maintains high quality after amplification, which can meet the requirements of high-quality and high-intensity communication.

[0080] A receiver bypass can be understood as a transmission channel with no loss or loss close to zero. The receiver bypass supports the transmission of communication signals without requiring signal amplification or filtering, further saving unnecessary losses and meeting ultra-low loss communication requirements. By separately setting up the low-noise amplification unit 312 and the receiver bypass, the functions of low-noise amplification and transmission processing of communication signals can be switched to match different communication requirements.

[0081] In one embodiment, the aggregation module 50 is integrated inside the first radio frequency transceiver 10 (for ease of illustration, the first radio frequency transceiver with the aggregation module 50 integrated is still shown as 10 in the figure).

[0082] like Figure 7 As shown, the first RF transceiver 10 is configured with a first transmission port and a second transmission port (R1 and R2 in the figure correspond to the first transmission port and the second transmission port, respectively). The first transmission port is connected to the aggregation module 50 and the first RF device 30, respectively, and the second transmission port is connected to the aggregation module 50 and the RF module 40, respectively. The first RF transceiver 10 can be understood as a packaged device, and the first and second transmission ports can be understood as the receive pin terminals of the packaged device, used to connect with the first RF device 30 and the RF module 40.

[0083] The aggregation module 50 is integrated inside the first RF transceiver 10. A first end of the aggregation module 50 is connected to the receiving channel, and multiple second ends of the aggregation module 50 can be connected to multiple transmission ports respectively. For example, one second end of the aggregation module 50 receives the communication signal processed by the first RF device 30 through the first transmission port, and another second end of the aggregation module 50 receives the first frequency band signal processed by the RF module 40 through the second transmission port, and aggregates the received signals before transmitting them to the receiving channel.

[0084] By connecting the aggregation module 50 integrated inside the first RF transceiver 10 with each transmission port of the first RF transceiver 10, and connecting each transmission port with the first RF device 30 and the RF module 40, the aggregation module 50 can perform aggregation processing on the signals received and processed by the first RF device 30 and the RF module 40. On the one hand, the aggregation module 50 cooperates with the receiving channel. By directly integrating the aggregation module 50 inside the first RF transceiver 10, the transmission path between the aggregation module 50 and the receiving channel can be shortened, while avoiding possible interference between the discrete aggregation module 50 and the first RF transceiver 10 at the interface position of the receiving channel, thus reducing the waste of signal energy. On the other hand, integrating the aggregation module 50 inside the first RF transceiver 10 can increase the integration of the first RF transceiver 10 and expand the aggregation function of the first RF transceiver 10, simplifying the peripheral structure while improving performance.

[0085] In one embodiment, the radio frequency module 40 and the aggregation module 50 are packaged as a second radio frequency device 60.

[0086] like Figure 8As shown, the second RF device 60 is configured with a second input port (Rxi2 in the figure), a fifth output port (Rx5 in the figure), and a second antenna port (Ant2 in the figure). The second input port is connected to the first RF device 30 and the aggregation module 50, respectively. The fifth output port is connected to the aggregation module 50 and the first RF transceiver 10, respectively. The second antenna port is connected to the second antenna ANT2. The RF module 40 and the aggregation module 50 are packaged into an integrated second RF device 60. The second input port, the second antenna port, and the fifth output port can be understood as RF pin terminals of the packaged device, used for connecting to the RF module 40, the antenna, and the first RF transceiver 10.

[0087] The communication signal received by the second antenna ANT2 is transmitted to the radio frequency module 40 in the second radio frequency device 60 via the second antenna port. The radio frequency module 40 receives and processes the first frequency band signal and transmits it to the aggregation module 50. The communication signal transmitted by the first radio frequency device 30 is transmitted to the aggregation module 50 via the second input port. After the aggregation module 50 aggregates the first frequency band signal and the communication signal, it transmits them to the receiving channel of the first radio frequency transceiver 10 via the fifth output port.

[0088] By encapsulating the aggregation module 50 and the radio frequency module 40 into a second radio frequency device 60, the aggregation module 50 can perform aggregation processing on the signals received and processed by the first radio frequency device 30 and the radio frequency module 40. On the one hand, the aggregation module 50 cooperates with the first radio frequency device 30 and the radio frequency module 40 respectively. By integrating the aggregation module 50 and the radio frequency module 40 into the second radio frequency device 60, the transmission path between the aggregation module 50 and the radio frequency module 40 can be shortened at least, while avoiding possible interference between the discrete aggregation module 50 and the first radio frequency device 30 at the connection point, thus reducing the waste of signal energy. On the other hand, integrating the aggregation module 50 and the radio frequency module 40 can increase the integration level of the radio frequency module 40 and expand its aggregation function, simplifying the peripheral structure while improving performance.

[0089] For example, there are multiple second input ports, and each of the multiple second input ports is connected to a corresponding multiple first radio frequency device 30. Thus, the second radio frequency device 60 can be connected to multiple first radio frequency devices 30. The aggregation module 50 can receive the first frequency band signals processed by the multiple first radio frequency devices 30 through the multiple second input ports, thereby realizing the aggregation of more first frequency band signals and thus achieving a greater improvement in the receiving performance of the receiving channel.

[0090] In one embodiment, the aggregation module 50 is disposed outside the first radio frequency device 30. For example, the aggregation module 50 is integrated inside the first radio frequency transceiver 10, or it is packaged with the radio frequency module 40 as a second radio frequency device 60. Alternatively, the aggregation module 50 is disposed outside the first radio frequency device 30, the radio frequency module 40, and the first radio frequency transceiver 10.

[0091] like Figure 9 As shown ( Figure 9 Taking the aggregation module 50 integrated inside the first RF transceiver 10 as an example, the first RF device 30 is configured with a third output port (Rx3 in the figure), a fourth output port (Rx4 in the figure), and a first antenna port (Ant1 in the figure) connected to the first antenna ANT1. The third output port is connected to the aggregation module 50, and the signal transmitted through the third output port is aggregated and processed by the aggregation module 50 before being transmitted to the first RF transceiver 10; the fourth output port is connected to the second RF transceiver 20, and the signal transmitted through the fourth output port is transmitted to the second RF transceiver 20. The first RF device 30 can be understood as a packaged device, and the first antenna port, third output port, and fourth output port can be understood as RF pin terminals of the packaged device, used for connection with the antenna, the first RF transceiver 10, and the second RF transceiver 20.

[0092] The first radio frequency device 30 includes: a first receiving module 310 connected to a first antenna port for receiving and processing communication signals transmitted through the first antenna port; and a second gating module connected to the first receiving module 310, a third output port, and a fourth output port, respectively, for connecting the first receiving module 310 to either the third or fourth output port. The third output port is connected to the aggregation module 50, and the fourth output port is connected to the second radio frequency transceiver 20. The description of the first receiving module 310 in the above embodiments is provided and will not be repeated here. By selectively connecting the first receiving module 310 to either the third or fourth output port, the second gating module can selectively transmit communication signals to either the first radio frequency transceiver 10 or the second radio frequency transceiver 20, thereby enabling the first radio frequency device 30 to be multiplexed in different communication standard systems.

[0093] By integrating the first receiving module 310 and the second gating module inside the first radio frequency device 30, the first radio frequency device 30 can receive and process first band signals and second band signals of different communication standards that are all within a preset frequency range. When the radio frequency system needs to support the high-order diversity of the first band signal and the reception and processing of the second band signal, the first radio frequency device 30 can realize the multiplexing of the reception and processing of different band signals, reduce the number of radio frequency modules 40, and reduce costs.

[0094] For example, the first receiving module 310 may include a filtering unit 311 and a low-noise amplification unit 312. For example, the first receiving module 310 may also include a receiving bypass. The filtering unit 311, the low-noise amplification unit 312, and the receiving bypass are described in the above embodiments.

[0095] It should be noted that in any of the above embodiments or combinations of embodiments, the example mainly focuses on the first radio frequency device 30 having a receiving function. In other embodiments, the first radio frequency device 30 may be configured with other functions based on the actual needs of the radio frequency system. The following are some optional examples for further explanation:

[0096] For example, such as Figure 10 As shown ( Figure 10 by Figure 9 (This is for illustrative purposes only.) The first receiving module 310 may be used only for amplifying the signal. The first radio frequency device 30 is also configured with a third input port for connecting to the first radio frequency transceiver 10. The first radio frequency device 30 also includes: a filtering module 340, a first transmitting module 350 and a fourth gating module 360.

[0097] The first transmitting module 350 receives the second frequency band signal to be transmitted through the third input port (Rxi3 in the figure) and processes the second frequency band signal. Transmission processing may include, for example, power amplification. The filtering module 340 filters the received signal. The fourth gating module 360 ​​is connected to the filtering module 340, the first receiving module 310, and the first transmitting module 350 respectively, and is used to connect the filtering module 340 to any one of the first receiving module 310 and the first transmitting module 350 to achieve switching of the transmit and receive functions of the first radio frequency device 30.

[0098] For example, such as Figure 11 As shown, the first RF device 30 may also have an eighth output port (Rx8 in the figure) and a fourth input / output port (Rxi4 in the figure), which are respectively connected to the second RF transceiver 20; the communication signal also includes a third frequency band signal, and the communication standard of the third frequency band signal is the same as that of the second frequency band signal; the RF device also includes a fourth receiving module 370, a second transmitting module 380 and a fifth gating module 390; wherein, the first end of the filtering module 340 is connected to the second antenna port, and the two second ends of the filtering module 340 are respectively connected to the fourth gating module 360 ​​and the fifth gating module 390, and the fifth gating module 390 is used to select the connection between the filtering module 340 and any one of the fourth receiving module 370 and the second transmitting module 380, so as to realize the switching of the transmission and reception of the third frequency band signal.

[0099] It should be noted that in any of the above embodiments or combinations of embodiments, the radio frequency module 40 is exemplified by having a receiving function. In other embodiments, the radio frequency module 40 may be configured with other functions based on the actual needs of the radio frequency system. The following are some optional examples for further explanation:

[0100] For example, such as Figure 12 As shown, the radio frequency module 40 can be configured with a third antenna port, a fifth input port (Rxi5 in the figure), and a ninth output port (Rx9 in the figure). The radio frequency module 40 may include a fifth receiving module 410, a third transmitting module 420, and a sixth gating module 430. The sixth gating module 430 is used to select to connect the third antenna port (Ant3 in the figure) to either the third receiving module 410 or the third transmitting module 420 to realize the switching of the transmission and reception function of the first frequency band signal.

[0101] For example, the fifth receiving module 410 may include a filtering unit and a low-noise amplification unit to perform filtering and low-noise amplification of the first frequency band signal.

[0102] For example, the third transmitting module 420 may include multiple transmitting units with different power modes, which can meet different power amplification requirements. Different power modes may include, for example, high / medium power modes (HPM / MPM), low power modes (LPM), etc.

[0103] It is understood that in any of the above embodiments or combinations of embodiments, the number of aggregation modules 50 can be one or more. Different numbers match different requirements of the radio frequency system.

[0104] In one embodiment, the first RF transceiver 10 includes multiple receiving channels in the same RF channel group; there are multiple aggregation modules 50, each aggregation module 50 is connected to a corresponding receiving channel, and each aggregation module 50 is connected to at least one first RF device 30 and at least one RF module 40. Through multiple aggregation modules 50 and multiple receiving channels, the performance of more receiving channels can be improved to achieve higher-order diversity reception, further enhancing the overall communication function of the RF system.

[0105] For example, the number of receiving channels and the number of aggregation modules 50 are two each. Taking the two aggregation modules 50 as being integrated inside the first RF transceiver 10, the first RF transceiver 10 is configured with four input ports. The first end of each aggregation module 50 is connected to a receiving channel in the RF channel group, and the two second ends of each aggregation module 50 are respectively connected to two input ports. Each aggregation circuit is connected to the first RF device 30 through one connected input port and to the RF module 40 through the other connected input port. The two aggregation modules 50 are connected to different input ports.

[0106] By connecting the two aggregation modules 50 integrated inside the first RF transceiver 10 to the four input ports, and connecting the four input ports to the corresponding first RF devices 30 and RF modules 40, each aggregation module 50 can aggregate the signals received and processed by one first RF device 30 or RF module 40. On the one hand, the two aggregation modules 50 correspond to the two receiving channels of the same RF channel group and cooperate with each other. By directly integrating the two aggregation modules 50 inside the first RF transceiver 10, the transmission path between each aggregation module 50 and the receiving channel can be shortened, while avoiding possible interference between the discrete aggregation modules 50 and the first RF transceiver 10 at the interface position of the receiving channel, thus reducing the waste of signal energy. On the other hand, integrating the aggregation modules 50 inside the first RF transceiver 10 can increase the integration of the first RF transceiver 10 and expand its aggregation function, simplifying the peripheral structure while improving performance.

[0107] The following example uses a 5G WIFI signal as the first frequency band signal, an N79 frequency band signal as the second frequency band signal, and two aggregation modules 50 integrated within the first RF transceiver 10. The aggregation module 50 includes a power divider. This example compares relevant technical embodiments with the embodiments of this application to further explain the above embodiments. (The figures illustrate optional components for each circuit and module; the connection relationships of optional components are shown in the figures. Depending on actual needs, some auxiliary components are also shown in the figures, such as 370 and 440, which correspond to coupling modules including couplers; 380 is a switching module):

[0108] Related technical embodiment 1:

[0109] like Figure 13 As shown, the Wi-Fi system and the cellular system are two independent systems, but they ultimately share the same access point (AP). The radio frequency front-end devices in the Wi-Fi system and the cellular system each only support the frequency band of their respective communication standard.

[0110] Related technical embodiment 2:

[0111] like Figure 14 As shown, in the WIFI system, the system includes four radio frequency circuits: Chain0 / 1 / 2 / 3. The four radio frequency circuits correspond to the four receiving channels of two radio frequency channel groups (the first radio frequency channel group and the second radio frequency channel group in the figure, respectively). Chain0 / 1 belongs to the same radio frequency channel group, while Chain2 / 3 belongs to another radio frequency channel group. The two radio frequency channel groups are independent of each other, and the four radio frequency circuits 20 are independent of each other.

[0112] Based on relevant technical embodiments 1 and 2, when the radio frequency system needs to support 5G WIFI and N79 band signals, the overall number of components in the radio frequency system is large. The radio frequency system cannot simultaneously improve the communication connection performance with a single communication server and reduce hardware costs while achieving high-order diversity of 5G WIFI.

[0113] Example 1 of this application:

[0114] like Figure 15 As shown, the radio frequency system includes four channels: Chain0 / 1 / 2 / 3, each corresponding to a radio frequency channel group (the first radio frequency channel group in the figure). Chain2 / 3 corresponds to two first radio frequency devices 30, multiplexing signals from the first and second frequency bands. Chain0 / 2 corresponds to one first radio frequency device 30 and one radio frequency module 40, respectively; the received 5G WIFI signals are aggregated through a power divider. Chain1 / 3 corresponds to one first radio frequency device 30 and one radio frequency module 40; the received 5G WIFI signals are aggregated through a power divider.

[0115] 5G WIFI pathway:

[0116] After the 5G WIFI band signal is input from Ant0 or Ant1, it is also selected by the DP3T switch to be input into the first RF device 30. The input 5G WIFI band signal is filtered by N79 / WIFI SAW and then selected by the SP2T switch for output. The selected output signal is amplified by LNA2, and it also supports bypassing the LNA2 for direct output. The amplified or bypassed 5G WIFI band signal is output from WIFI RX through the selective switch SPDT.

[0117] N79 pathway:

[0118] The transmitted signal is input from the N79 TX port to the internal N79 PA and amplified before being output. The amplified N79 signal is switched to SAW for filtering via the SP2T switch. The signal after filtering by N79 / WIFI SAW is coupled and finally selected for output (Ant0 or Ant1) via DP3T. The N79 received signal is input from Ant0 or Ant1 and is also selected for input via DP3T switch. The input N79 signal is filtered by N79 / WIFI SAW and then selected for output via SP2T switch. The selected output signal is amplified by LNA2, and can also be bypassed directly without going through LNA. The amplified or bypassed N79 received signal is output from N79 RX via selective switch SPDT.

[0119] In this embodiment, on the one hand, Chain2 / 3 can simultaneously receive both N79 and 5GWIFI signals, reducing the hardware cost of the radio frequency system; on the other hand, the radio frequency system can achieve 5GWIFI high-order diversity and can achieve 1T4R and 1T2R*2 transceiver functions.

[0120] In the 1T4R architecture, 1T can be understood as one transmit path, where any one of Chain0 / 1 can be selected. 4R can be understood as four receive paths, where Chain0 / 1 / 2 / 3 are aggregated to improve receive performance. In this structure, compared to related technical embodiments, the transmit path can remain unchanged. The main difference is that Chain0 / 3 are aggregated into one receive path via a power divider, and Chain1 / 2 are aggregated into another receive path via a power divider. The performance improvement comes from adding a Chain3 to the original Chain0 and adding a Chain2 to Chain1. See Table 1 for details.

[0121] Table 1

[0122]

[0123] In the 1T2R*2 architecture, compared to related technical embodiments, the transmit path remains Chain0 / 1, while the receive path adds an additional receive path to each of the original single receive paths to improve receive performance. In this architecture, the first transmit path (Chain0) and the second transmit path (Chain1) are completely independent and can operate in parallel. The first receive path includes Chain0 and Chain3, and the second receive path includes Chain1 and Chain2. See Table 2 for details.

[0124] Table 2

[0125]

[0126] Example 2 of this application:

[0127] like Figure 16 As shown, the two power dividers are integrated inside the wireless receiver of the first RF transceiver 10, which simplifies the peripheral structure of the first RF transceiver 10 while improving 5G WIFI performance.

[0128] This embodiment optimizes cost and performance by combining multiple RF front-end devices into a multi-path architecture. It merges the discrete WIFI device single receiving path with the N79 receiving path to form a first RF device 30 that supports two frequency band signals. It also transforms the original two independent receivers into two mutually cooperating performances, thereby achieving performance optimization.

[0129] This application also provides a radio frequency device, which is configured with a sixth output port, a seventh output port, and a third antenna port for connection with a third antenna; the radio frequency device includes a second receiving module and a third gating module.

[0130] The second receiving module, connected to the third antenna port, is used to receive and process the communication signals transmitted through the third antenna port. The communication signals include a first frequency band signal and a second frequency band signal with different communication standards. The first frequency band signal is a short-range wireless standard signal, and the first and second frequency bands are respectively within a preset frequency range. The third gating module is connected to the second receiving module, the sixth output port, and the seventh output port, respectively, and is used to connect the second receiving module to any one of the sixth and seventh output ports. The sixth output port is used to connect to the first radio frequency transceiver, which is used to obtain the first frequency band signal from the received communication signals. The seventh output port is used to connect to the second radio frequency transceiver, which is used to obtain the second frequency band signal from the received communication signals.

[0131] The radio frequency device in this embodiment is similar to the first radio frequency device described in the previous embodiment, and will not be repeated here. The radio frequency device in this embodiment can support two different communication standards and signals within a preset frequency range, namely a first frequency band signal and a second frequency band signal, thereby reducing hardware costs.

[0132] This application also provides an electronic device, including a radio frequency system as described in any one or a combination of the above embodiments. Based on the radio frequency system of any of the above embodiments, the electronic device can reduce hardware costs. In embodiments including an aggregation module, it can also improve the communication connection performance with a single communication server, further reducing hardware costs.

[0133] like Figure 17As shown, further, taking the aforementioned electronic device as mobile phone 11 as an example for explanation, specifically, as follows... Figure 17 As shown, the mobile phone 11 may include a memory 21 (which optionally includes one or more computer-readable storage media), a processor 22, a peripheral device interface 23, a radio frequency system 24 as described in the above embodiments, and an input / output (I / O) subsystem 26. These components optionally communicate via one or more communication buses or signal lines 29. Those skilled in the art will understand that... Figure 17 The mobile phone 11 shown does not constitute a limitation on the mobile phone and may include more or fewer components than shown, or combine certain components, or have different component arrangements. Figure 17 The various components shown are implemented in hardware, software, or a combination of both, including one or more signal processing and / or application-specific integrated circuits.

[0134] Memory 21 optionally includes high-speed random access memory, and also optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Exemplary examples include software components stored in memory 21 such as an operating system 211, a communication module (or instruction set) 212, a global positioning system (GPS) module (or instruction set) 213, etc.

[0135] The processor 22 and other control circuits can be used to control the operation of the mobile phone 11. The processor 22 can be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors, power management units, audio codec chips, application-specific integrated circuits, etc.

[0136] The processor 22 can be configured to implement control algorithms for controlling the use of the antenna in the mobile phone 11. The processor 22 can also issue control commands for controlling various switches in the radio frequency system 24.

[0137] I / O subsystem 26 couples input / output peripherals on mobile phone 11, such as the keypad and other input control devices, to peripheral interface 23. I / O subsystem 26 optionally includes a touchscreen, buttons, a tone generator, an accelerometer (motion sensor), an ambient light sensor and other sensors, light-emitting diodes and other status indicators, data ports, etc. For example, a user can control the operation of mobile phone 11 by supplying commands via I / O subsystem 26, and can use the output resources of I / O subsystem 26 to receive status information and other outputs from mobile phone 11. For example, a user can press button 261 to turn the phone on or off. The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.

[0138] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
