[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0044] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0045] In the current standard heterodyne transceiver subsystem, one antenna corresponds to one RF transceiver module. Each RF transceiver module is composed of more than ten components, including a switching switch (usually composed of a duplexer or a tri-flexor), a digital step attenuator (DSA), a band pass filter (BPF), a low noise amplifier (LNA), a high power RF amplifier (HPA), and a RF variable gain amplifier (RF VGA). The structure is relatively complex, and it is difficult to increase the number of antennas in scenarios with limited space. When a multi-input and multi-output MIMO system needs to be established, it is even more difficult to achieve because the number of components needs to be increased exponentially.

[0046] In some space-limited application scenarios, such as smartphones, the layout of antennas is limited due to the narrow space, and the components on the PCB are closely arranged. Complex hardware design and multi-antenna layout may increase the complexity of the design, resulting in a long design cycle, high cost or more human resources, which will increase manufacturing costs, increase product defect rates, and ultimately lead to rising costs. In addition, with the increase in demand for RF performance, the exponential increase in the number of components may not be able to resist signal interference, resulting in reduced device performance or unstable communication quality, and failure to achieve the expected performance level.

[0047] In response to these defects and problems, the present application provides a radio frequency integrated system module and a wireless communication module, which can reduce the complexity of the system when adding antennas. When a multi-input and multi-output system needs to be established, it is only necessary to connect multiple target antennas as needed, without the need for additional components, thereby improving the performance of the radio frequency integrated system module.

[0048] The first embodiment of the present application provides a radio frequency integrated system module, such as Figure 1 The radio frequency integrated system module includes: a frequency band separation unit 101, a radio frequency multiplexing unit 102, a voltage-controlled bandpass filtering unit 103 and a channel selection unit 104.

[0049] The frequency band separation unit includes N three-way devices, N is greater than 1, and the input end of the three-way device is used to connect the target antenna, and output the target signal of the target antenna to the RF multiplexing unit from the target output end of the three output ends of the three-way device according to different frequency bands.

[0050] The radio frequency multiplexing unit is used to output the target signal to the target path of the voltage-controlled bandpass filtering unit according to the antenna type of the target antenna.

[0051] The voltage-controlled bandpass filter unit is used to adjust the voltage of the target signal of each target channel so that the target channel passes the target signal of a preset frequency band.

[0052] The channel selection unit is used to send the target signal to the RF output end under the action of the first control signal, or to receive the RF transmission signal from the RF input end under the action of the second control signal, so as to send the RF transmission signal to the target antenna through the voltage-controlled bandpass filter unit, the RF multiplexing unit and the frequency band separation unit.

[0053] The RF integrated system module can reduce the number of components used, and each triax of the frequency band separation unit can be connected to a target antenna respectively, reducing the complexity of the system when adding antennas. When a multi-input and multi-output system needs to be established, it is only necessary to connect multiple target antennas as required without adding additional components, thereby improving the performance of the RF integrated system module.

[0054] In one embodiment, N is equal to 4M, and M is greater than or equal to 1. Next, the specific composition of the RF integrated system module is described by taking M equal to 1 as an example. It should be understood that if M is equal to 2, the number of corresponding components can be doubled, and the same is true when M is equal to 3, which will not be repeated.

[0055] When M is equal to 1, that is, N is equal to 4, the schematic diagram of the RF integrated system module is as follows Figure 2 The frequency band separation unit 101 includes a first three-way switch, a second three-way switch, a third three-way switch and a fourth three-way switch. The radio frequency multiplexing unit 102 includes a radio frequency multiplexer with twelve inputs and four outputs. The voltage-controlled bandpass filtering unit 103 includes a first voltage-controlled bandpass filter with four channels and a second voltage-controlled bandpass filter with four channels, wherein the first voltage-controlled bandpass filter is used for voltage-controlled bandpass filtering processing of radio frequency receiving signals, and the second voltage-controlled bandpass filter is used for voltage-controlled bandpass filtering processing of radio frequency transmitting signals. The channel selection unit 104 includes a first four-channel selector and a second four-channel selector, wherein the first four-channel selector is used for channel selection of radio frequency receiving signals, and the second four-channel selector is used for channel selection of radio frequency transmitting signals.

[0056] In this embodiment, each three-way device can be connected to a target antenna, and the type of the target antenna is not limited, for example, it can be a 3G antenna, a 4G antenna, a 5G antenna, a Wi-Fi antenna, a Bluetooth antenna, etc. The three-way device can output the target signal of the target antenna from the target output end of the three output ends of the three-way device according to different frequency bands to the RF multiplexing unit. The RF multiplexing unit outputs the target signal to the target channel of the voltage-controlled bandpass filter unit according to the antenna type of the target antenna. The voltage-controlled bandpass filter unit can adjust the voltage of the target signal of each target channel so that the target channel passes the target signal of the preset frequency band. The channel selection unit can send the target signal to the RF output end under the action of the first control signal, or receive the RF transmission signal from the RF input end under the action of the second control signal, so as to send the RF transmission signal to the target antenna through the voltage-controlled bandpass filter unit, the RF multiplexing unit and the frequency band separation unit.

[0057] In this embodiment, each triax can be connected to a target antenna respectively, which reduces the complexity of the system when adding antennas. When a multi-input and multi-output system needs to be established, it is only necessary to connect multiple target antennas as needed without adding additional components, thereby improving the performance of the RF integrated system module.

[0058] In one embodiment, the schematic diagram of the RF integrated system module is as follows: Figure 3 The RF integrated system module also includes an antenna configuration unit. The antenna configuration unit is used to obtain an antenna configuration file and configure the antenna type of the target antenna according to the antenna configuration file.

[0059] In this embodiment, the target antenna connected to the three-way device can be configured into any type by the antenna configuration unit according to the antenna configuration file obtained. For example, the target antenna connected to the first three-way device can be a 5G antenna, a Wi-Fi antenna, or any other type of antenna. The target antenna connected to the second three-way device can be a 5G antenna, a Wi-Fi antenna, or any other type of antenna. Of course, the third and fourth three-way devices can also be antennas of any type without restriction. Through the antenna configuration unit, there is no need to restrict each antenna to be fixedly connected to a certain port, which improves the flexibility of antenna configuration.

[0060] In one embodiment, the schematic diagram of the RF integrated system module is as follows: Figure 4 The RF integrated system module also includes: a first automatic gain control low noise amplifier and a second automatic gain control low noise amplifier.

[0061] The first automatic gain control low noise amplifier is connected in series between the first voltage-controlled bandpass filter and the first four-channel selector, and is used to receive and amplify the radio frequency receiving signal output from the first voltage-controlled bandpass filter; the second automatic gain control low noise amplifier is connected in series between the second voltage-controlled bandpass filter and the second four-channel selector, and is used to receive and amplify the radio frequency transmitting signal output from the second four-channel selector.

[0062] In one embodiment, the schematic diagram of the RF integrated system module is as follows: Figure 5 The RF integrated system module also includes a RF power amplifier unit, which includes a first RF power amplifier and a second RF power amplifier.

[0063] The first RF power amplifier is used to power amplify the RF received signal when the amplification factor of the RF received signal by the first automatic gain control low noise amplifier is not within a preset range; the second RF power amplifier is used to power amplify the RF transmitted signal when the amplification factor of the RF transmitted signal by the second automatic gain control low noise amplifier is not within a preset range.

[0064] In this embodiment, the connection relationship of each device is as follows:

[0065] The input end of the first three-way device is connected to the first target antenna, the first output end of the first three-way device is connected to the first input end of the radio frequency multiplexer, the second output end of the first three-way device is connected to the second input end of the radio frequency multiplexer, and the third output end of the first three-way device is connected to the third input end of the radio frequency multiplexer;

[0066] The input end of the second three-way device is connected to the second target antenna, the first output end of the second three-way device is connected to the fourth input end of the radio frequency multiplexer, the second output end of the second three-way device is connected to the fifth input end of the radio frequency multiplexer, and the third output end of the second three-way device is connected to the sixth input end of the radio frequency multiplexer;

[0069] The first output end of the radio frequency multiplexer is connected to the first path of the first voltage-controlled bandpass filter and the first path of the second voltage-controlled bandpass filter;

[0070] The second output end of the radio frequency multiplexer is connected to the second path of the first voltage-controlled bandpass filter and the second path of the second voltage-controlled bandpass filter;

[0071] The third output terminal of the radio frequency multiplexer is connected to the third channel of the first voltage-controlled bandpass filter and the third channel of the second voltage-controlled bandpass filter;

[0072] The fourth output terminal of the radio frequency multiplexer is connected to the fourth channel of the first voltage-controlled bandpass filter and the fourth channel of the second voltage-controlled bandpass filter.

[0073] In this embodiment, each triax of the frequency band separation unit can be connected to a target antenna respectively, which reduces the complexity of the system when adding antennas. When a multi-input multi-output system needs to be established, it is only necessary to connect multiple target antennas as needed without adding additional components, thereby improving the performance of the RF integrated system module.

[0074] In a specific embodiment, the RF integrated system module is as follows Figure 6 , the RF integrated system module can use a 4-port antenna, wherein A represents a frequency band separation unit, U31 represents a first three-way device, U32 represents a second three-way device, U33 represents a third three-way device, and U34 represents a fourth three-way device. B represents a RF multiplexing unit, wherein U51 represents a RF multiplexer. C represents a first voltage-controlled bandpass filter, G represents a second voltage-controlled bandpass filter, wherein U41, U42, U43, and U44 represent four channels of the first voltage-controlled bandpass filter, respectively, and U46, U49, U52, and U45 represent four channels of the second voltage-controlled bandpass filter, respectively. D represents a first automatic gain control low noise amplifier, and K represents a second automatic gain control low noise amplifier, wherein U39, U38, U40, and U35 represent four channels of the first automatic gain control low noise amplifier, respectively, and U48, U47, U50, and U37 represent four channels of the second automatic gain control low noise amplifier, respectively. E represents the first four-channel selector, namely U44, F represents the second four-channel selector, namely U36. I represents the first RF power amplifier, namely U53, J represents the second RF power amplifier, namely U54. H represents the antenna, wherein U27, U28, U29, and U30 represent a target antenna respectively.

[0075] Assuming that the antenna signal is inputting / outputting one of the antenna ports, the working process of the RF integrated system module is described below. The antenna environment setting is the U30 antenna connection. For example, the frequency of this antenna is RF (Tx: 1920-1980MHz / Rx: 2110-2170MHz). The three-way device includes three bands: L, M and H. The L band corresponds to 0.5-1GHz, the M band corresponds to 1.4-2.7GHz, and the H band corresponds to 3-5GHz. The antenna can pass through the M band of the three-way device. At this time, the RF multiplexer only turns on the D1 channel, and the other channels are turned off. Specifically, the switching logic of the channel of the RF multiplexer can be controlled by, for example, a 12-bit binary number. Each binary number represents a channel. When the value of the binary number is 1, it means that the channel is turned on. When the value is 0, it means that the channel is turned off.

[0076] At this time, the output of the RF multiplexer corresponds to the RF IN OUT2 channel, which is connected to the U42 channel of the first voltage-controlled bandpass filter. The first voltage-controlled bandpass filter only allows the frequency band of the set frequency to pass, which can eliminate noise and achieve the passing RF frequency by controlling the voltage, thereby preventing the filter from being reused. The first automatic gain control low noise amplifier receives and amplifies the RF signal input from the U42 of the first voltage-controlled bandpass filter. In this process, if the amplification is too high or too low, it will affect the system, so it will send a feedback signal to RCPx to report the current status and adjust the gain through RGTx. If it is difficult to adjust the gain group or frequency deviation, etc., a secondary adjustment is performed through RVTx for more precise adjustment.

[0077] Since the first four-channel selector inputs the RF signal through D1, the D1 switch is turned on and the other switches are turned off. The signal input through D1 is output through the final "RF_RX_OUT" port. The fin selector is controlled by CTL1, thereby completing the RF signal reception process.

[0078] For RF transmission signals, the Tx (transmit) frequency range of the RF (Tx: 1920-1980 / Rx: 2110-2170) transmission / reception frequency is 1920-1980Mhz, and the process of the RF signal is as follows:

[0079] The RF transmit signal is input through the RF_TX_IN input of the second four-channel selector. Since the frequency band is 1920-1980Mhz, for example, the D1 switch of the second four-channel selector is ON at this time, and the other channels are OFF. The RF transmit signal is sent to the RF_IN_OUT2 of the RF multiplexer through the second channel U49 of the second voltage-controlled bandpass filter and U47 of the second automatic gain control low noise amplifier, and then connected to the M band of the first three-way switch through D1 of U51, and the RF transmit signal is sent out through the antenna U30, completing the RF signal transmission process.

[0080] In this embodiment, the antenna function can be used selectively, for example, the first antenna port can be set with a 3G antenna, the second antenna port can be set with a Wifi antenna, or the two can be interchanged, or any other combination of antenna types, without limitation, and 2X2 MIMO and 4X4 MIMO systems can be formed by 4 antennas without adding additional components. In addition, conventional means of expanding the number of antennas require corresponding additions of RF input and output components, and a set of input and output requires at least 11 components, while this embodiment can support the input of 4 antennas without adding additional components, which can significantly reduce the number of components used and facilitate smaller and more compact circuit design.

[0081] In one embodiment, the radio frequency multiplexer is used to determine the internal connection between the twelve inputs and the four outputs according to the antenna type of the target antenna under the action of the path control signal.

[0082] In this embodiment, the RF multiplexer can determine the internal connection between the twelve inputs and the four outputs according to the antenna type of the target antenna under the action of the path control signals CTLB and CTL0, and can select the corresponding connected path as needed, thereby realizing the function of arbitrarily connecting different antennas to the antenna port. The RF multiplexer can be connected to the antenna configuration unit to obtain the antenna type of the target antenna from the antenna configuration unit.

[0083] In one embodiment, the radio frequency integrated system module is packaged in a system-level package or an application-specific integrated circuit package.

[0084] In this embodiment, the RF integrated system module can adopt a system-in-package (SIP) or an application-specific integrated circuit (ASIC), thereby making the overall product compact and reducing the cost by packaging it into a module.

[0085] Based on the same technical concept, the second embodiment of the present application provides a wireless communication module, which includes the radio frequency integrated system module described in any one of the first embodiments.

[0086] The device embodiments described above are merely illustrative, wherein the units described as separate components may or may not be physically separated, and the components shown as units may or may not be physical units, that is, they may be located in one place or distributed on multiple network units.
