Description

Technical Field

[0001] The embodiments of the present application relate to the field of terminal technology, and in particular to a signal transceiver device, a filtering control method, a device, a terminal and a storage medium. Background Art

[0002] With the development of terminal technology, the internal structure of the terminal is becoming more and more complex, resulting in interference between the circuits corresponding to the functional modules of the terminal, thereby affecting the performance of the functional modules. For example, the Global Positioning System (GPS) of the terminal is a signal receiving circuit with a center frequency of 1575.42MHz and a bandwidth of 2MHz. The transmission frequency range of the low-frequency (Low Band, LB) long-term evolution technology (Long Term Evolution, LTE) circuit is 699MHz-915 MHz. Therefore, the second harmonic of individual frequency bands of LTE LB will just fall within the GPS band, thereby interfering with the performance of GPS.

[0003] In the related art, in order to reduce the interference between different modules, filter circuits are added to different modules to filter out interference signals. For example, filter circuits are respectively provided in the above-mentioned LTE LB circuit and GPS circuit, so that the second harmonic generated by the LTE LB circuit is filtered out in the LTE LB circuit, and the fundamental wave generated by the received LTE LB circuit is filtered out in the GPS circuit, thereby reducing the interference to the GPS.

[0004] In the above-mentioned related technologies, the GPS circuit and the LTE LB circuit may not work at the same time, or the interference signal generated by the GPS is not within the receiving range of the GPS circuit, that is, it does not cause interference to the GPS circuit. In this case, filtering the GPS circuit and the LTE LB circuit will cause a large insertion loss of the circuit, affecting the performance of the circuit. Summary of the invention

[0041] In some embodiments, the signal transceiver 130 is used to include multiple channels for signal transmission and signal reception. Figure 2 , which shows a schematic diagram of a signal transceiver device output by an exemplary embodiment of the present application, the signal transceiver device 130 is applied in the terminal 100, including: a signal transmitting module 131, a signal receiving module 132 and a filtering module 133; the signal transmitting module 131 includes a first antenna component 1311 and a signal transmitting component 1312, the first antenna component 1311 is connected to the signal transmitting component 1312; the signal receiving module 132 includes a second antenna component 1321 and a signal receiving component 1322, the second antenna component 1321 is connected to the signal receiving component 1322;

[0042] The filter module 133 includes a switch component 1331 and a filter component 1332, the filter component 1332 is connected to the switch component 1331, one end of the switch component 1331 is connected between the first antenna component 1311 and the signal transmitting component 1312, and the other end of the switch component 1331 is connected between the second antenna component 1321 and the signal receiving component 1322;

[0043] Among them, the switch component 1331 is used to control the filtering component 1332 to be connected with at least one of the signal transmitting module 131 and the signal receiving module 132 when both the signal transmitting module 131 and the signal receiving module 132 are in working state, so as to filter the signal of at least one of the signal transmitting module 131 and the signal receiving module 132.

[0044] In the embodiment of the present application, the filter component 1332 is controlled by the switch component 1331 to perform filtering, thereby realizing control of the filter component 1332 based on the working mode of the signal transceiver device 130, so that the filtering process can be flexibly adjusted, thereby reducing the insertion loss of the signal transmitting module 131 and the signal receiving module 132, and improving the circuit performance of the signal transmitting module 131 and the signal receiving module 132.

[0045] In some embodiments, see Figure 3 , the signal transmission module 131 is an LTE LB module, and the signal transmission component 1312 includes a signal transceiver (Transceiver), a power amplifier (Power Amplifier, PA), a low noise amplifier (Low Noise Amplifier, LNA) and a duplexer (Duplexer). The first antenna component 1311 includes an antenna switch and a first antenna. Among them, one end of the signal transceiver is connected to one end of the power amplifier, the other end of the power amplifier is connected to one end of the duplexer, the other end of the duplexer is connected to one end of the low noise amplifier, the other end of the low noise amplifier is connected to the other end of the signal transceiver, the other end of the duplexer is connected to the antenna switch, and the antenna switch is connected to the first antenna. In some embodiments, the signal transceiver is used to control the frequency of the transmitted signal, the power amplifier is used to amplify the power of the signal transmitted by the signal transceiver, the low noise amplifier is used to amplify the signal received by the signal transceiver, the duplexer is used to isolate the signal transmitted and received by the signal transceiver, the antenna switch is used to control the working state of the first antenna component, and the first antenna component is used to radiate or receive signals.

[0046] In some embodiments, see Figure 4 , the signal receiving module 132 is a GPS module, the signal receiving component 1322 includes an integrated circuit chip (IC), a surface acoustic wave filter (SAW) and a low noise amplifier (LNA), and the second antenna component 1321 includes a second antenna. Among them, one end of the integrated circuit chip is connected to one end of the surface acoustic wave filter, the other end of the surface acoustic wave filter is connected to one end of the low noise amplifier, and the other end of the low noise amplifier is connected to the second antenna. In some embodiments, the integrated circuit chip is used to process the received signal, the surface acoustic wave filter is used to filter out the signal of the specified frequency, the low noise amplifier is used to amplify the received signal, and the second antenna is used to receive the signal.

[0047] In some embodiments, see Figure 5, the filtering module also includes a memory 1333; one end of the memory 1333 is connected between the first antenna component 1311 and the signal transmitting component 1312; the other end of the memory 1333 is connected to the switch component 1331; wherein the memory 1333 is used to collect the working frequency of the signal transmitting module 131;

[0048] The switch component 1331 is also used to control the filter component 1332 to be connected with at least one of the signal transmitting module 131 and the signal receiving module 132 when both the signal transmitting module 131 and the signal receiving module 132 are in working state and if the working frequency is within the target frequency range, and the target frequency range is the working frequency range of the signal receiving module 132.

[0049] The target frequency range is determined based on the center frequency and bandwidth of the signal receiving module 132. For example, if the signal receiving module 132 is a GPS module, the center frequency of the GPS module is 1575.42 MHz, and the bandwidth of the GPS module is 2 MHz, then the target frequency range is 1574.42 MHz to 1576.42 MHz. In some embodiments, the memory 1333 obtains the signal transmitted by the signal transmitting component 1312, parses the signal, and obtains the operating frequency of the signal transmitting module 131. In some embodiments, the memory 1333 obtains the signal transmitted by the signal transmitting component 1312, parses the signal, obtains the frequency corresponding to the fundamental wave of the signal, and determines the operating frequency based on the frequency corresponding to the fundamental wave. For example, if the operating frequency is the frequency of the second harmonic of the fundamental wave, then the operating frequency is twice the frequency corresponding to the fundamental wave.

[0050] In some embodiments, the switch component 1331 determines the switch state of the filter component 1332 based on the working mode of the signal transceiver device 130, and controls the conduction state of the filter component 1332 through different switch states to perform filtering. Referring to Table 1, the working modes of the signal transceiver device include working mode 1, working mode 2 and working mode 3, wherein, in the state of working mode 3, the switch component 1331 determines the conduction state of the filter component 1332 based on the working frequency and the target frequency range. In working mode 1, the switch state of the switch component 1331 is state a, in working mode 2, the switch state of the switch component 1331 is state b, in working mode 3, and the working frequency is not within the target frequency range, the switch state is state c, and in working mode 3, and the working frequency is within the target frequency range, the switch state is state d.

[0051] Table 1

[0052] Working Mode Switch Status Working Mode 1 a Working Mode 2 b Working mode 3, and the working frequency is not within the target frequency range c Working mode 3, and the working frequency is within the target frequency range d

[0053] Among them, working mode 1 is a mode in which the signal transmitting module 131 works alone and the signal receiving module 132 does not work. The switch state a indicates that the filter component 1332 is not enabled. Figure 6 In this case, the signal transmitting module 131 does not need to start the filtering component 1332 when in working state, thus saving resources. At the same time, there is no need to filter the signal transmitted or received by the signal transmitting module 131, thus reducing the insertion loss on the signal transmitting module 131 and improving the performance of the signal transmitting module 131.

[0054] Working mode 2 is a mode in which the signal receiving module 132 works alone and the signal transmitting module 131 does not work. The switch state b indicates that the filter component 1332 is not enabled. Figure 7 In this case, since the signal transmitting module 131 is not working, it will not interfere with the signal receiving module 132. Therefore, there is no need to start the filtering component 1332, which saves resources. At the same time, there is no need to filter the signal received by the signal receiving module 132, which reduces the insertion loss on the signal receiving module 132 and improves the performance of the signal receiving module 132.

[0055] Working mode 3 is a mode in which both the signal transmitting module 131 and the signal receiving module 132 work. When the working frequency is not within the target frequency range, the signal transmitted or received by the signal transmitting module 131 is not within the bandwidth of the signal receiving module 132, that is, the signal transmitted or received by the signal transmitting module 131 will not affect the signal receiving module 132. Therefore, the switch state c indicates that the filter component 1332 is not enabled, see Figure 8 In this case, since the signal transmitted or received by the signal transmitting module 131 is not within the bandwidth of the signal receiving module 132, it will not interfere with the signal receiving module 132. Therefore, there is no need to start the filtering component 1332, which saves resources. At the same time, there is no need to filter the signal received or transmitted by the signal transmitting module 131 and the signal received by the signal receiving module 132, which reduces the insertion loss on the signal transmitting module 131 and the signal receiving module 132, and improves the performance of the signal receiving module 132 and the signal receiving module 132.

[0056] Working mode 3 is a mode in which both the signal transmitting module 131 and the signal receiving module 132 work. When the working frequency is within the target frequency range, the signal transmitted or received by the signal transmitting module 131 is within the bandwidth of the signal receiving module 132, that is, the signal transmitted or received by the signal transmitting module 131 will affect the signal receiving module 132. Therefore, the switch state d indicates that the filter component 1332 is enabled, see Fig. 9In this case, the filtering component 1332 is started in time to filter the signal receiving module 132 and the signal transmitting module 131, which reduces the interference of the signal receiving module 132, ensures the signal quality of the signal receiving module 132, and improves the performance of the signal receiving module 132.

[0057] In an embodiment of the present application, in a mode in which both the signal transmitting module 131 and the signal receiving module 132 are working, the operating frequency of the signal transmitting module 131 is obtained through the memory 1333, and based on the operating frequency and the target frequency range, it is determined whether to turn on the filter component 1332, so that when no interference is generated between the signal transmitting module 131 and the signal receiving module 132, the filter component 1332 can be not used, thereby avoiding the filter component 1332 from filtering the signal transmitting module 131 and the signal receiving module 132 when no interference is generated between the signal transmitting module 131 and the signal receiving module 132, thereby ensuring the circuit performance of the signal transmitting module 131 and the signal receiving module 132.

[0058] In some embodiments, the switch component 1331 is any device capable of controlling the conduction state of the filter component 1332. For example, the switch component 1331 controls the conduction state of the filter component 1332 by controlling the impedance converter through a group of mobile industry processor interfaces (MIMP) or a group of general purpose input output interfaces (GPIO).

[0059] In some embodiments, see Fig.10 , the filter component 1332 includes a first filter 1332-1 and a second filter 1332-2;

[0060] The first filter 1332-1 and the second filter 1332-2 are respectively connected to the switch component 1331;

[0061] The switch component 1331 is used to control the first filter 1332-1 to be connected with the signal transmitting module 131 to filter the signal transmitting module 131, and to control the second filter 1332-2 to be connected with the signal receiving module 132 to filter the signal receiving module 132 when both the signal transmitting module 131 and the signal receiving module 132 are in working state and the working frequency is within the target frequency range.

[0062] In some embodiments, the filter component 1332 includes a first filter 1332-1 and a second filter 1332-2. In some embodiments, the first filter 1332-1 is connected to the signal transmitting module 131, and the second filter 1332-2 is connected to the signal receiving module 132. Accordingly, the switch component 1331 is used to control the conduction state of the first filter 1332-1 and the second filter 1332-2.

[0063] In the embodiment of the present application, the signal transmitting module 131 and the signal receiving module 132 are filtered by the first filter 1332-1 and the second filter 1332-2 respectively. In this way, the performance requirements of the first filter 1332-1 and the second filter 1332-2 are relatively low, and the signal transmitting module 131 and the signal receiving module 132 can be filtered at the same time, thereby improving the circuit performance of filtering the signal transmitting module 131 and the signal receiving module 132.

[0064] In some embodiments, the filter component 1332 includes a third filter 1332-3, and the third filter 1332-3 is an adjustable filter;

[0065] The third filter 1332-3 is connected to the switch component 1331;

[0066] The switch component 1331 is used to control the third filter 1332-3 to be connected with the signal transmitting module 131 or the signal receiving module 132 when both the signal transmitting module 131 and the signal receiving module 132 are in working state and if the working frequency is within the target frequency range, so as to filter the signal of the signal transmitting module 131 or the signal receiving module 132.

[0067] The third filter 1332-3 is an adjustable filter. Fig.11 , the third filter 1332-3 is controlled by the switch component 1331, and based on the operating frequency of the signal transmitting module 131, the target module is determined from the signal transmitting module 131 and the signal receiving module 132; based on the operating frequency of the signal transmitting module 131, the target filtering range is determined; the third filter 1332-3 is controlled to be connected with the target module to filter the target filtering range on the target module. In some embodiments, the switch component 1331 determines the target module based on the influence of the second harmonic generated by the signal transmitting module 131 on the signal receiving module 132 and the influence of the fundamental wave generated by the signal transmitting module 131 received by the signal receiving module 132 on the signal receiving module 132, and determines the target filtering range based on the signal that needs to be filtered out in the target module, thereby controlling the third filter 1332-3 to filter the target module for the target filtering range.

[0068] In the embodiment of the present application, the signal of the signal transmitting module 131 or the signal receiving module 132 is filtered through the third filter 1332-3, and only one filter is needed for filtering, thereby improving the circuit performance and saving costs.

[0069] See also Fig.12 , which shows a flow chart of a circuit control method shown in an exemplary embodiment of the present application. The method includes:

[0070] Step S1201: The terminal determines the working mode of the signal transceiver.

[0071] Step S1202: When the working mode of the signal transceiver device is that both the signal transmitting module and the signal receiving module are in working state, the terminal controls the filtering component to be connected with at least one module of the signal transmitting module and the signal receiving module to filter the signal of at least one module of the signal transmitting module and the signal receiving module.

[0072] In an embodiment of the present application, when the working mode of the signal transceiver device is that both the signal transmitting module and the signal receiving module are in working state, the filter component is controlled to perform filtering, thereby realizing control of the filter component based on the working mode of the signal transceiver device. In this way, the filtering process can be flexibly adjusted, thereby reducing the signal transmitted by the signal transmitting module and the insertion loss of the signal receiving module, and improving the signal transmitted by the signal transmitting module and the circuit performance of the signal receiving module.

[0073] In some embodiments, before the control filter component is connected to at least one of the signal transmitting module and the signal receiving module, the method further includes:

[0074] Determine a target frequency range, where the target frequency range is an operating frequency range of the signal receiving module;

[0075] Determine the operating frequency of the signal transmission module;

[0076] If the operating frequency is within the target frequency range, the step of controlling the filter component to conduct with at least one of the signal transmitting module and the signal receiving module is performed.

[0077] In an embodiment of the present application, in a mode in which both the signal transmitting module and the signal receiving module are working, the signal frequency of the signal transmitted by the signal transmitting module is obtained through a memory, and based on the signal frequency and the target frequency, it is determined whether to start the filtering component, thereby avoiding the use of the filtering component when no interference is generated between the signal transmitting module and the signal receiving module, thereby avoiding the filtering component filtering the signal transmitting module and the signal receiving module when no interference is generated between the signal transmitting module and the signal receiving module, thereby ensuring the circuit performance of the signal transmitting module and the signal receiving module.

[0078] In some embodiments, the filter assembly includes a first filter and a second filter, and the control filter assembly is connected to at least one of the signal transmitting module and the signal receiving module, including:

[0079] The first filter is controlled to be connected to the signal transmitting module, and the second filter is controlled to be connected to the signal receiving module.

[0080] In an embodiment of the present application, the signal transmitting module and the signal receiving module are filtered by the first filter and the second filter respectively. In this way, the performance requirements of the first filter and the second filter are relatively low, and the signal transmitting module and the signal receiving module can be filtered at the same time, thereby improving the circuit performance of the signal transmitting module and the signal receiving module for filtering.

[0081] In some embodiments, the filter component includes a third filter; the control filter component is connected to at least one of the signal transmitting module and the signal receiving module, including:

[0082] Determine a target module from the signal transmitting module and the signal receiving module based on the operating frequency of the signal transmitting module;

[0083] Based on the operating frequency of the signal transmission module, determine the target filtering range;

[0084] The third filter is controlled to be connected to the target module so as to perform filtering on the target module within the target filtering range.

[0085] In the embodiment of the present application, the signal of the signal transmitting module or the signal receiving module is filtered by the third filter, and only one filter is needed for filtering, thereby improving the circuit performance and saving costs.
