[0033] Combine the following Figures 1 to 10 An antenna transceiver circuit 100 and an electronic device according to an embodiment of the present application are described.

[0034] First, as Figure 1As shown, an embodiment of the present application provides an antenna transceiver circuit 100, including: a signal transceiver component 110; a radio frequency integrated component 120, which is electrically connected to the signal transceiver component 110, and the radio frequency integrated component 120 has at least two working modes; an antenna tuning component 140, which is electrically connected to the radio frequency integrated component 120, and the antenna tuning component 140 has at least two working modes; an antenna component 160, which is electrically connected to the antenna tuning component 140, and the antenna component 160 has at least two working modes; a frequency detection component 170, which is electrically connected to the signal transceiver component 110, the radio frequency integrated component 120, the antenna tuning component 140 and the antenna component 160; wherein the frequency detection component 170 is used to detect a first frequency band of a first radio frequency signal sent by the signal transceiver component 110 or a second frequency band of a second radio frequency signal received by the antenna component 160, and the radio frequency integrated component 120, the antenna tuning component 140 and the antenna component 160 determine the working mode according to the first frequency band or the second frequency band.

[0035] In an embodiment of the present application, the antenna transceiver circuit 100 includes a signal transceiver component 110, a radio frequency integrated component 120, an antenna tuning component 140, an antenna component 160 and a frequency detection component 170. The signal transceiver component 110 and the radio frequency integrated component 120 are electrically connected, and radio frequency signals can be transmitted between the two. The radio frequency integrated component 120 and the antenna tuning component 140 are electrically connected, and radio frequency signals can be transmitted between the two. The radio frequency tuning component and the antenna component 160 are electrically connected, and radio frequency signals can be transmitted between the two. Then, the first radio frequency signal emitted by the signal transceiver component 110 can enter the antenna component 160 through the radio frequency integrated component 120 and the antenna tuning component 140, and the second radio frequency signal received by the antenna component 160 can enter the signal transceiver component 110 through the antenna tuning component 140 and the radio frequency integrated component 120, thereby realizing the transmission and reception of radio frequency signals.

[0036] Among them, the RF integrated component 120 has at least two working modes, the antenna tuning component 140 has at least two working modes, and the antenna component 160 has at least two working modes. The frequency detection component 170 and the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 are all electrically connected, and the frequency detection component 170 can determine the first frequency band of the first RF signal, so that the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 adjust the working mode according to the first frequency band, so that the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 all work in a working mode matching the first frequency band. The frequency detection component 170 can also determine the second frequency band of the second RF signal, so that the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 adjust the working mode according to the second frequency band, so that the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 all work in a working mode matching the second frequency band, so that the antenna transceiver circuit 100 can adapt to multiple frequency bands.

[0037] As described above, the present application sets up a radio frequency integrated component 120, an antenna tuning component 140 and an antenna component 160 with multiple working modes, and detects the frequency band of the radio frequency signal through a frequency detection component 170. The radio frequency integrated component 120, the antenna tuning component 140 and the antenna component 160 adjust the working mode according to the frequency band of the radio frequency signal, so that the antenna transceiver circuit 100 can match radio frequency signals of multiple frequency bands, and the total number of lines of the antenna transceiver circuit 100 is reduced, and the area of ​​the circuit board occupied by the antenna transceiver circuit 100 is reduced, which is helpful for the layout of components in electronic equipment.

[0038] That is, the present application simplifies the path of the antenna transceiver circuit 100, reduces the area occupied by the antenna transceiver circuit 100 on the circuit board, simplifies the design of the antenna, and makes the antenna component 160 modular and reusable in different frequency bands, thereby reducing costs. In addition, the development efficiency of the antenna transceiver circuit 100 can be improved, while making the electronic equipment more advanced.

[0039] like Fig.10 As shown, the present application simplifies the receiving path, the transmitting path and the antenna assembly 160 , so that the signal transceiver assembly 110 only needs one receiving path, one transmitting path and the antenna assembly 160 at least.

[0040] like Figure 2As shown, as a possible implementation, the frequency detection component 170 includes: at least two filters 172, which are electrically connected to the signal transceiver component 110 and the antenna component 160; a first controller 174, which is electrically connected to the filter 172, the RF integrated component 120, the antenna tuning component 140 and the antenna component 160, and the first controller 174 determines the first frequency band of the first RF signal or the second frequency band of the second RF signal according to the filter 172 through which the first RF signal or the second RF signal passes.

[0041] Specifically, the frequency detection component 170 includes a filter 172 and a first controller 174, the number of filters 172 is at least two, the filter 172 and the first controller 174 are electrically connected, the filter 172 and the signal transceiver component 110 and the antenna component 160 are electrically connected, the filter 172 can receive the first RF signal sent by the signal transceiver component 110, the first RF signal passes through the filter 172 and enters the controller, the controller determines the first RF signal through the filter 172 to determine the first frequency band of the first RF signal, the filter 172 can receive the second RF signal received by the antenna component 160, and the antenna component 160 receives the first After the second RF signal is transmitted, it is forwarded to the filter 172. The second RF signal passes through the filter 172 and enters the first controller 174. The controller determines that the second RF signal passes through the filter 172 to determine the second frequency band of the second RF signal. Then, the first controller 174 outputs the signal of the current frequency band to the RF integrated component 120, the antenna tuning component 140 and the antenna component 160. After the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 receive the signal of the current frequency, they switch to the corresponding working mode, thereby realizing the switching of the working frequency band of the antenna transceiver circuit 100. The above structure of the frequency band detection of the RF signal is simple and has high stability.

[0042] The present application optimizes the RF front end, introduces the design of the frequency detection component 170, and designs the transmitting and receiving RF frequency detection schemes. The frequency band signal of the transmitted signal is detected by the output end of the signal transceiver component (Transmitter-Receiver, TRX), and the frequency band of the received signal is detected by the output end of the antenna component 160.

[0043] like Figure 2 As shown, as a possible implementation, at least two filters 172 are arranged in parallel, and the filtering parameters of the at least two filters 172 are different.

[0044] Specifically, at least two filters 172 are arranged in parallel, and the filtering parameters of the at least two filters 172 are different, so that the radio frequency signal of a specific frequency band can only pass through the corresponding filter 172, thereby ensuring the accuracy of determining the frequency band of the radio frequency signal.

[0045] like Figure 2 As shown, the internal structure of the frequency detection component 170 is on the right side of the arrow. The RF signal is input and passes through filters 172 of different frequency bands to reach the first controller 174. RF signals of different frequency bands can only pass through specific filters 172. After receiving the input of the specific filter 172, the first controller 174 controls the output signal of the output end, thereby controlling the RF integrated component 120, the antenna tuning component 140 and the antenna component 160. The frequency detection component 170 can control multiple channels at the same time to achieve simultaneous transmission and reception and multiple-input-multiple-output (MIMO) design.

[0046] The RF front-end pathway is mainly increased according to the different frequency bands. Through the frequency detection component, the frequency band of the current RF signal is intelligently detected to drive the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 to adapt intelligently.

[0047] like Figure 3 As shown, as a possible implementation, the RF integrated component 120 includes: at least two RF circuits 122, electrically connected to the signal transceiver component 110; a second controller 124, electrically connected to the frequency detection component 170, and the second controller 124 determines whether the RF circuit 122 is on or off according to the first frequency band or the second frequency band.

[0048] Specifically, the RF integrated component 120 includes a RF circuit 122 and a second controller 124, the number of the RF circuits 122 is at least two, the second controller 124 is electrically connected to the frequency detection component 170, the signal of the current frequency band output by the frequency detection component 170 is transmitted to the second controller 124, and the second controller 124 controls the on and off of the RF circuit 122, so that the RF circuit 122 that matches the signal of the current frequency band is turned on, and the other RF circuits 122 are disconnected, thereby realizing that one RF integrated component 120 supports multiple operating frequency bands.

[0049] The present application realizes the modularization of the RF integrated component 120 and the reuse of the RF integrated component 120, thereby simplifying the RF front-end path. The RF integrated component 120 includes at least two RF circuits 122, each of which has one receiving path (Receive, RX) and one transmitting path (Transmit, TX) for each frequency band, which is simplified to multiplexing one receiving path RX and one transmitting path TX for all frequency bands.

[0050] like Figure 4As shown, as a possible implementation, the antenna tuning component 140 includes: at least two tuning circuits 142, electrically connected to the RF integrated component 120; a third controller 144, electrically connected to the frequency detection component 170, and the third controller 144 determines whether the tuning circuit 142 is on or off according to the first frequency band or the second frequency band.

[0051] Specifically, the antenna tuning component 140 includes a tuning circuit 142 and a third controller 144, the number of the tuning circuits 142 is at least two, the third controller 144 and the frequency detection component 170 are electrically connected, the signal of the current frequency band output by the frequency detection component 170 is transmitted to the third controller 144, and the third controller 144 controls the on and off of the tuning circuit 142, so that the tuning circuit 142 that matches the signal of the current frequency band is turned on, and the other tuning circuits 142 are turned off, thereby realizing that one antenna tuning component 140 supports multiple operating frequency bands.

[0052] The antenna tuning component 140 has at least one optional tuning circuit 142 built in to solve the problem of adapting to different frequency bands. The signal sent by the frequency detection component 170 drives the antenna tuning component 140 to select a working mode suitable for the signal frequency band at this time, that is, the antenna tuning component 140 selects the tuning circuit 142 corresponding to the frequency band through the signal output by the frequency detection component 170 to turn on.

[0053] like Figure 5 As shown, as a possible implementation, the antenna assembly 160 includes: at least one multiplexing antenna 162, the multiplexing antenna 162 having at least two operating frequency bands; wherein the multiplexing antenna 162 adjusts the operating frequency band according to the first frequency band or the second frequency band, so that the operating frequency band of the multiplexing antenna 162 conforms to the first frequency band or the second frequency band.

[0054] Specifically, the antenna assembly 160 includes at least one multiplexing antenna 162, and the multiplexing antenna 162 has at least two working frequency bands, so that one multiplexing antenna 162 supports multiple working frequency bands, reduces the number of antennas in the antenna transceiver circuit 100, and reduces the difficulty of arranging antennas in electronic devices.

[0055] The multiplexing antenna 162 adjusts the working frequency band according to the first frequency band of the first frequency band signal so that the working frequency band of the multiplexing antenna 162 conforms to the first frequency band. After the frequency detection component 170 detects the first frequency band of the first RF signal, the signal sent is sent to the antenna component 160, and then the multiplexing antenna 162 switches the state according to the first frequency band, thereby adjusting the working frequency band of the multiplexing antenna 162 so that the working frequency band of the multiplexing antenna 162 conforms to the first frequency band.

[0056] The multiplexing antenna 162 adjusts the working frequency band according to the second frequency band of the second frequency band signal so that the working frequency band of the multiplexing antenna 162 conforms to the second frequency band. After the frequency detection component 170 detects the second frequency band of the second RF signal, the signal sent is sent to the antenna component 160, and then the multiplexing antenna 162 switches the state according to the second frequency band, thereby adjusting the working frequency band of the multiplexing antenna 162 so that the working frequency band of the multiplexing antenna 162 conforms to the second frequency band.

[0057] The present application realizes modularization of the antenna assembly 160 by reusing the antenna 162, simplifies the number of antennas, and standardizes the antenna assembly 160, which can be reused in different frequency bands, and one area can have one reused antenna 162.

[0058] The modular antenna assembly 160 is driven by a frequency detector. The modular antenna assembly 160 has a fifth transceiver and a fifth transmitter 168 to realize signal interaction. The signal of the fifth transceiver is input by the frequency detection assembly 170, and its function is to identify the frequency band on the current path. The signal of the fifth transmitter 168 is the output port of the second radio frequency signal, which is output to the frequency detection assembly 170 to determine the frequency band of the second radio frequency signal.

[0059] The modular antenna assembly 160 identifies the antenna frequency and state required at this time through the fifth transceiver terminal, automatically matches the best working mode, and can be used as an independent multi-channel antenna.

[0060] like Figure 1 As shown in the figure, as a possible implementation, the signal transceiver component 110 has a first receiving end 112 and a first transmitting end 114, the RF integrated component 120 has a second receiving end 126, a third receiving end 128, a second transmitting end 130 and a third transmitting end 132, and the antenna tuning component 140 has a fourth receiving end 146, a fourth transmitting end 148 and a first transceiver end 150; wherein the first transmitting end 114 is electrically connected to the second receiving end 126 and the frequency detection component 170, and the second transmitting end 130 and the fourth receiving end 146 are electrically connected to the frequency detection component 170. 6 is electrically connected, the first receiving end 112 is electrically connected to the third transmitting end 132, the third receiving end 128 is electrically connected to the fourth transmitting end 148, the first transceiver end 150 is electrically connected to the antenna assembly 160, the first RF signal passes through the first transmitting end 114, the second receiving end 126, the second transmitting end 130, the fourth receiving end 146 and the first transceiver end 150 in sequence, and the second RF signal passes through the first transceiver end 150, the fourth transmitting end 148, the third receiving end 128, the third transmitting end 132 and the first receiving end 112 in sequence.

[0061] Specifically, the signal transceiver component 110 has a first receiving end 112 and a first transmitting end 114; the RF integrated component 120 has a second receiving end 126, a third receiving end 128, a second transmitting end 130 and a third transmitting end 132; the antenna tuning component 140 has a fourth receiving end 146, a fourth transmitting end 148 and a first transceiver end 150.

[0062] Among them, the first transmitting end 114 is electrically connected to the second receiving end 126 and the frequency detection component 170, the second transmitting end 130 is electrically connected to the fourth receiving end 146, the first receiving end 112 is electrically connected to the third transmitting end 132, the third receiving end 128 is electrically connected to the fourth transmitting end 148, and the first transceiver end 150 is electrically connected to the antenna component 160.

[0063] The signal transceiver component 110 sends out a first RF signal from the first transmitting end 114. The first RF signal enters the second receiving end 126 of the RF integrated component 120 and is then sent out from the second transmitting end 130. After that, the first RF signal enters the fourth receiving end 146 of the antenna tuning component 140 and is then sent out from the first transceiver end 150. After that, the first RF signal enters the antenna component 160.

[0064] After the antenna component 160 receives the second RF signal, the second RF signal enters the first transceiver terminal 150 of the antenna tuning component 140, and is then sent out by the fourth transmitting terminal 148 of the antenna tuning component 140. After that, the second RF signal enters the third receiving terminal 128 of the RF integrated component 120, and is then sent out by the third transmitting terminal 132 of the RF integrated component 120. After that, the second RF signal enters the first receiving terminal 112 of the signal transceiver component 110.

[0065] The above structure reduces the circuits between the signal transceiver component 110 , the radio frequency integrated component 120 and the antenna tuning component 140 , and reduces the area occupied by the antenna transceiver circuit 100 on the circuit board.

[0066] like Figure 1 , Figure 7 and Figure 8 As shown, as a possible implementation, the antenna assembly 160 has a second transceiver terminal 164, a fifth receiving terminal 166 and a fifth transmitting terminal 168, the second transceiver terminal 164 is electrically connected to the first transceiver terminal 150, and the fifth receiving terminal 166 and the fifth transmitting terminal 168 are both electrically connected to the frequency detection assembly 170.

[0067] Specifically, the antenna component 160 has a second transceiver end 164, a fifth receiving end 166 and a fifth transmitting end 168. The second transceiver end 164 of the antenna component 160 and the first transceiver end 150 of the antenna tuning component 140 are electrically connected. The fifth receiving end 166 and the fifth transmitting end 168 of the antenna component 160 are both electrically connected to the frequency detection component 170.

[0068] The signal transceiver component 110 sends out a first RF signal from the first transmitting end 114. The first RF signal enters the second receiving end 126 of the RF integrated component 120 and is then sent out from the second transmitting end 130. After that, the first RF signal enters the fourth receiving end 146 of the antenna tuning component 140 and is then sent out from the first transceiver end 150. After that, the first RF signal enters the second transceiver end 164 of the antenna component 160.

[0069] After the antenna component 160 receives the second RF signal, it enters the first transceiver end 150 of the antenna tuning component 140 through the second transceiver end 164, and is then sent out by the fourth transmitting end 148 of the antenna tuning component 140. After that, the second RF signal enters the third receiving end 128 of the RF integrated component 120, and is then sent out by the third transmitting end 132 of the RF integrated component 120. After that, the second RF signal enters the first receiving end 112 of the signal transceiver component 110.

[0070] The above structure reduces the circuit between the antenna tuning component 140 and the antenna component 160, and reduces the area occupied by the antenna transceiver circuit 100 on the circuit board.

[0071] like Figure 1 As shown, as a possible implementation, the frequency detection component 170 has a sixth receiving terminal 176, a seventh receiving terminal 178, a sixth transmitting terminal 180, a seventh transmitting terminal 182 and an eighth transmitting terminal 184, the sixth receiving terminal 176 is electrically connected to the first transmitting terminal 114, the seventh receiving terminal 178 is electrically connected to the fifth transmitting terminal 168, the sixth transmitting terminal 180 is electrically connected to the RF integrated component 120, the seventh transmitting terminal 182 is electrically connected to the antenna tuning component 140, and the eighth transmitting terminal 184 is electrically connected to the fifth receiving terminal 166.

[0072] Specifically, the frequency detection component 170 has a sixth receiving terminal 176, a seventh receiving terminal 178, a sixth transmitting terminal 180, a seventh transmitting terminal 182 and an eighth transmitting terminal 184. The sixth receiving terminal 176 of the frequency detection component 170 is electrically connected to the first transmitting terminal 114 of the signal transceiver component 110, the seventh receiving terminal 178 of the frequency detection component 170 is electrically connected to the fifth transmitting terminal 168 of the antenna component 160, the sixth transmitting terminal 180 of the frequency detection component 170 is electrically connected to the RF integrated component 120, the seventh transmitting terminal 182 of the frequency detection component 170 is electrically connected to the antenna tuning component 140, and the eighth transmitting terminal 184 of the frequency detection component 170 is electrically connected to the antenna component 160.

[0073] The signal transceiver component 110 sends a first RF signal from the first transmitting end 114, and the first RF signal enters the second receiving end 126 of the RF integrated component 120. Figure 1 and Figure 6 As shown, the sixth receiving end 176 of the frequency detection component 170 is entered, and the frequency detection component 170 determines the first frequency band of the first RF signal. Thereafter, the sixth transmitting end 180 of the frequency detection component 170 sends the signal of the current frequency band to the RF integrated component 120, the seventh transmitting end 182 of the frequency detection component 170 sends the signal of the current frequency band to the antenna tuning component 140, and the eighth transmitting end 184 of the frequency detection component 170 sends the signal of the current frequency band to the antenna component 160, and the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 switch to corresponding working modes.

[0074] Afterwards, the first RF signal is sent out by the second transmitting end 130 , then enters the fourth receiving end 146 of the antenna tuning component 140 , and then is sent out by the first transceiver end 150 , and then enters the second transceiver end 164 of the antenna component 160 .

[0075] After the antenna assembly 160 receives the second RF signal, it enters the first transceiver end 150 of the antenna tuning assembly 140 through the second transceiver end 164. Figure 1 and Figure 6 As shown, the seventh receiving end 178 of the frequency detection component 170 is entered, and the frequency detection component 170 determines the second frequency band of the second RF signal. After that, the sixth transmitting end 180 of the frequency detection component 170 sends the signal of the current frequency band to the RF integrated component 120, the seventh transmitting end 182 of the frequency detection component 170 sends the signal of the current frequency band to the antenna tuning component 140, and the eighth transmitting end 184 of the frequency detection component 170 sends the signal of the current frequency band to the antenna component 160, and the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 switch to corresponding working modes.

[0076] Afterwards, the second RF signal is sent out from the fourth transmitting end 148 of the antenna tuning component 140, and then enters the third receiving end 128 of the RF integrated component 120, and then is sent out from the third transmitting end 132 of the RF integrated component 120, and then enters the first receiving end 112 of the signal transceiver component 110.

[0077] The above structure reduces the circuits between the frequency detection component 170 and the signal transceiver component 110, the RF integrated component 120, the antenna tuning component 140 and the antenna component 160, thereby reducing the circuit board area occupied by the antenna transceiver circuit 100.

[0078] Among them, the signal transceiver component 110 is a radio frequency front-end docking module, which is mainly responsible for modulation and demodulation of radio frequency signals.

[0079] The RF integrated component 120 adds a second controller 124 as a trigger for frequency detection, driving the RF integrated component 120 to select a path that adapts to the frequency. The RF integrated component 120 also includes other basic RF requirement modules such as filters 172, power amplifiers, and combiners.

[0080] The frequency detection component 170 outputs relevant frequency control instructions to the RF integration component 120 , the antenna tuning component 140 and the antenna component 160 by detecting the receiving end RX and the transmitting end TX.

[0081] The antenna tuning component 140 is added with a third controller 144 as a trigger for frequency detection, driving the antenna tuning component 140 to select an antenna matching path that adapts to the frequency. The antenna tuning component 140 also includes a basic requirement module for multiple matching circuits.

[0082] The antenna assembly 160 is a standardized antenna module that can be formed into a form corresponding to the highest efficiency according to the requirements of different frequency bands. It can be reused in different projects to achieve antenna standardization and reduce costs.

[0083] The transmission path TX and the reception path RX of the RF integrated component 120 , the antenna tuning component 140 and the antenna component 160 are independent, that is, when TX and RX are transmitting and receiving at the same time, they do not affect each other.

[0084] Specifically, Fig. 9As shown, when a certain frequency band is used, such as frequency band (Band) N, the first RF signal is transmitted from the first transmitting end of the signal transceiver component, and the frequency detection component 170 detects that the frequency of Band N is F1 at this time, and outputs the frequency F1 instruction to the RF integrated component 120, the antenna tuning component 140 and the antenna component 160. The RF integrated component 120, the antenna tuning component 140 and the antenna component 160 detect that the frequency band of the first RF signal is F1, and adjust the internal path or form to match the frequency band F1. That is, the RF integrated component 120 selects the best transmission path for the RF signal of the F1 frequency band, the antenna tuning component 140 selects the antenna matching adapted to the RF signal of the F1 frequency band, and the antenna component 160 is adjusted to adapt to the form of the F1 frequency band. At this time, the RF path, antenna path and antenna form belong to the maximum state of signal efficiency of the frequency band Band N.

[0085] When the frequency detection component 170 detects that the first RF signal belongs to the F1 frequency band, the RF integrated component 120, the antenna tuning component 140 and the antenna component 160 will all be adjusted to adapt to the RF signal of the F1 frequency band to ensure optimal performance at this time.

[0086] Similarly, when a certain frequency band, such as frequency band (Band) M, the second RF signal is input from the antenna component 160, the frequency detection component 170 detects that the frequency band of Band M is F2 at this time, and outputs the instruction of frequency band F2 to the RF integrated component 120, the antenna tuning component 140 and the antenna component 160. The RF integrated component 120, the antenna tuning component 140 and the antenna component 160 detect that the frequency band of the second RF signal is F2, and adjust the internal path or form to match the RF signal of frequency band F2. That is, the RF integrated component 120 selects the best receiving path for the RF signal of frequency band F2, the antenna tuning component 140 selects the antenna matching adapted to the RF signal of frequency band F2, and the antenna component 160 is adjusted to adapt to the form of the RF signal of frequency band F2. At this time, the RF path, antenna path and antenna form belong to the maximum state of signal efficiency of frequency band Band M.

[0087] The transmitting path TX and receiving path RX of the antenna transceiver circuit 100 are independent. The frequency detection component 170 controls simultaneous transmission and reception and switching of different paths. It can also perform multi-antenna transmission and reception, such as 2×2 MIMO dual antennas and 4×4 MIMO four antennas in the frequency band.

[0088] The present application solves the technical problems of multiple channels and a large number of antennas in the RF front-end in the related technologies, reduces the area occupied by the RF front-end and the antenna, and standardizes devices (such as modular antennas and frequency detection components 170, etc.), which not only reduces device costs, but also standardized modules can improve development and debugging efficiency, allowing the space, appearance and cost of electronic equipment to be made more extreme, thereby improving user experience.
