[0003] In existing technologies, communication modules are generally connected to the RF cable of an external antenna via an RF connector on the module. Typically, the TRX path of the module is connected to the TRX antenna, and the TX path is connected to the TX antenna.

[0004] However, if the RF cable of the TRX antenna is disconnected from the RF connector of the module, the module will be unable to communicate with the base station. Utility Model Content

[0005] This application provides a communication module and an M.2 device to solve the technical problem that the module will be unable to communicate with the base station when the RF cable of the TRX antenna and the RF connector of the module are disconnected.

[0006] In a first aspect, this application provides a communication module, comprising: a communication body; a first radio frequency unit (RFU), wherein the communication body is connected to a first antenna via the first RNU; a second RNU, wherein the communication body is connected to a second antenna via the second RNU; and a microstrip line connected between the first RNU and the second RNU.

[0007] For example, the first radio frequency device and the second radio frequency device described above may be pluggable connectors.

[0008] For example, the communication module described above may further include a duplexer; the duplexer is located between the communication body and the first radio frequency unit.

[0011] For example, the communication module may further include a filter located between the communication body and the frequency divider.

[0012] For example, the communication module described above further includes a power amplifier located between the communication body and the first radio frequency unit.

Detailed Implementation

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0023] To address the technical problem in the prior art where the module cannot communicate with the base station when the RF cable of the TRX antenna and the RF connector of the module are disconnected, this application provides a communication module that enables the module to still communicate with the base station even when the RF cable of the TRX antenna and the RF connector of the module are disconnected.

[0024] Figure 1 This is a schematic diagram of a communication module provided in an embodiment of this application. Figure 1 As shown, the above communication module includes: Communication subject 102; The first radio frequency unit 104, wherein the aforementioned communication subject is connected to the first antenna via the first radio frequency unit; The second radio frequency unit 106, wherein the aforementioned communication subject is connected to the second antenna via the second radio frequency unit; Microstrip line 108 is connected between the first RF device and the second RF device.

[0025] The first radio frequency unit 104 and the second radio frequency unit 106 mentioned above are simply different radio frequency units, and the terms "first", "second" or "number" do not constitute a limitation on the order or structure.

[0026] The aforementioned microstrip line connects the first and second radio frequency (RF) units. The connection method is as follows: if the first and second RF units are parallel, the line is connected perpendicularly to them. If the line connecting the connection points of the first and second RF units is not perpendicular to them, then when connecting the first and second RF units, a perpendicular line is drawn from the connection point of one RF unit to the other RF unit to deploy the microstrip line. The perpendicular line stops at a predetermined distance from the other RF unit, and the microstrip line is deployed parallel to the other RF unit until it reaches the connection point of the other RF unit. Then, the microstrip line is connected perpendicularly to the connection point of the other RF unit. Figure 2 This is an example of a microstrip line deployment. One radio frequency device 22 is perpendicular to another radio frequency device 21 from its connection point, then becomes a parallel line at a preset distance, and finally becomes a perpendicular line again to the connection point of radio frequency device 21.

[0027] If the line connecting the connection points of the two radio frequency devices is perpendicular to the two radio frequency devices, then the connection points of the two radio frequency devices can be directly connected to deploy the microstrip line.

[0028] If the two radio frequency units (RFUs) are not parallel, when deploying the microstrip line, one RFU is used as a reference. The microstrip line is deployed perpendicular to the RFU, starting from the connection point of the RFU. During deployment, the microstrip line follows a trajectory parallel or perpendicular to the RFU until it connects to the connection point of the other RFU. It is ensured that the distance between the microstrip line and each RFU is greater than the aforementioned preset length. This preset length is a constraint value used to limit the distance between the microstrip line and the first and second RFUs, thereby avoiding interference with the signal transmission of the microstrip line.

[0029] For example, the first radio frequency device and the second radio frequency device described above can be pluggable connectors, also known as plug-out connectors or quick-connect / disconnect connectors, which are devices used to conveniently and quickly connect and disconnect electrical or electronic equipment.

[0030] For example, the communication module described above may also include an M.2 interface. The communication module can be connected to a computer via the M.2 interface to provide related functions to the computer; the specific functions provided depend on the type of communication module.

[0031] For example, the communication module further includes a frequency divider, one end of which is connected to the second radio frequency unit, and the other end of which is connected to the communication main body and the microstrip line respectively.

[0032] For example, a filter can be set between the aforementioned communication entity and the aforementioned frequency divider to filter the signal and remove interference.

[0033] For example, the communication module further includes a duplexer; the duplexer is located between the communication body and the first radio frequency unit.

[0034] For example, the communication module further includes a power amplifier located between the communication body and the first radio frequency unit. The power amplifier can be used to amplify the signal sent from the communication body to the first radio frequency unit, thereby making the transmitted signal clearer. Different amplification power settings can be configured for the power amplifier. A control module can be included in the communication body, which sets the amplification power of the power amplifier based on the detected strength of the transmitted signal.

[0035] For example, the communication module described above further includes a signal detection module located in the communication body, used to detect the signal received by the second radio frequency device.

[0036] For example, the communication module further includes a coordination module for receiving signals from the signal detection module and coordinating the signal strengths of the signals received by the first radio frequency device and the second radio frequency device.

[0037] The detection module and coordination module are used to detect the received signal of the communication subject and coordinate the receiving components when both the first and second radio frequency units are functioning normally. The detection module can also detect the signal strength of the signal transmitted by the first radio frequency unit. The function of detecting and coordinating the receiving components involves detecting the signal strength of the signals received by the first and second radio frequency units, passing the signal strength data to the coordination module, and then controlling the reception time period of the first and second radio frequency units based on the signal strength values.

[0038] This embodiment utilizes a communication module comprising: a communication unit; a first radio frequency unit (RFU), wherein the communication unit is connected to a first antenna via the first RNU; a second RNU, wherein the communication unit is connected to a second antenna via the second RNU; and a microstrip line connected between the first RNU and the second RNU. This allows the communication unit to communicate with the base station via the microstrip line using another antenna when either the first or second antenna malfunctions. This achieves the effect that the module can still communicate with the base station even when the RFCable of the TRX antenna and the RF Connector of the module are disconnected.

[0039] Figure 3This is a schematic diagram of an exemplary communication module. The communication unit is connected to a first radio frequency unit (Connector_1) via a duplexer. The duplexer is used to divide the transmit and receive signals of the TRX channel to obtain separate transmit and receive signals. The transmit (TX) channel of the TRX channel can be equipped with a power amplifier (PA). The communication unit is connected to antenna 1 via the first radio frequency unit. Antenna 1 is a TRX antenna, which communicates with the base station. Simultaneously, the communication unit is also connected to a second radio frequency unit (Connector_2), which is connected to antenna 2. Antenna 2 is a receive (RX) antenna. The communication unit communicates with the base station via the RX antenna.

[0040] If antenna 1 is properly connected to the first radio frequency unit, the communication entity communicates with the base station through antenna 1. If antenna 1 is disconnected from the first radio frequency unit, the communication entity communicates through the microstrip line (…). Figure 2 The dashed line between the first and second radio frequency units is connected to antenna 2, and communication with the base station is achieved through antenna 2.

[0041] When the communication unit connects to the second antenna via a microstrip line, the signal from the second radio frequency unit is divided by a frequency divider. The divided signals are then used for the RX channel of the communication unit and the microstrip line, respectively, allowing the communication unit to simultaneously transmit and receive signals through antenna 2. A filter (Surface Acoustic Wave, SAW) for the RX channel can be set between the communication unit and the frequency divider to filter the signal.

[0042] For example, Connector_1 is an LMH Band & UCB TRX RF Connector, Connector_2 is a UCB 8RX RF Connector, and the frequency divider is an LMH Band & UCB divider. When the RF cable of antenna 1 is attached to Connector_1, the TRX uses antenna 1 to communicate with the base station. When the RF cable of antenna 1 is not attached to Connector_1, the LMH Band TRX path passes through the microstrip line (…). Figure 2 (Dashed line) Antenna 2 communicates with the base station. Different frequency combinations can be selected through a frequency divider to achieve different frequency reuse, such as: LMH Band & UCB, Low Band & MH Band, etc. Furthermore, the device does not include a double-pole double-throw switch, saving components and eliminating the risk of switch failure.

[0043] This embodiment also provides an M.2 device, including: The device body; a first radio frequency unit, wherein the device body is connected to a first antenna via the first radio frequency unit; a second radio frequency unit, wherein the device body is connected to a second antenna via the second radio frequency unit; and a microstrip line connected between the first radio frequency unit and the second radio frequency unit.

[0044] For example, an M.2 device may include an M.2 interface through which the M.2 device can be connected to a smart device to provide services to the smart device.

[0045] Figure 4 This is a schematic diagram of an exemplary M.2 device. The transceiver, or transceiver unit, is the main body of the device and serves as the transceiver for the M.2 device. It is connected to the first RF unit Connector_1 via a duplexer. The duplexer is used for signal frequency division in the TRX channel to obtain the transmit and receive signals. The transmit (TX) channel in the TRX channel can be equipped with a power amplifier (PA). The M.2 device is connected to antenna 1 via the first RF unit. Antenna 1 is a TRX antenna, which communicates with the base station. Simultaneously, the transceiver is also connected to a second RF unit Connector_2, which is connected to antenna 2. Antenna 2 is a receive (RX) antenna. The M.2 device communicates with the base station via the RX antenna.

[0046] If antenna 1 is properly connected to the first radio frequency unit, the M.2 device communicates with the base station through antenna 1. If antenna 1 is disconnected from the first radio frequency unit, the M.2 device communicates with the base station through the microstrip line (…). Figure 4 The dashed line between the first and second radio frequency units is connected to antenna 2, and communication with the base station is achieved through antenna 2.

[0047] When the M.2 device is connected to the second antenna via a microstrip line, the signal from the second radio frequency unit is divided by a frequency divider. The divided signals are then used for both the RX channel of the M.2 device and the microstrip line transmission signal, allowing the M.2 device to simultaneously transmit and receive signals through antenna 2. A filter (Surface Acoustic Wave, SAW) for the RX channel can be set between the M.2 device and the frequency divider to filter the signal.
