[0057] In order to make the objectives, technical solutions and advantages of the present application more clear, the embodiments of the present application will be further described in detail below with reference to the accompanying drawings.

[0058] It should be clear that the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0059] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0060] In the description of the present application, it should be understood that the terms "first", "second", etc. are only used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence, nor can they be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0061] In the production process of existing wireless RF communication modules, it is necessary to adjust the power control factor inside the module so that the module's transmission power reaches the specified target power range. Figure 1 As shown, the wireless RF communication module to be calibrated is placed in a wireless module production fixture, and the wireless RF communication module to be calibrated is controlled to send a signal through the production calibration program. The power is measured by an integrated tester (referred to as the integrated tester), and then the power control factor inside the module is adjusted based on the measured power, target power and known line loss, so that the module's transmission power reaches the specified target power range.

[0062] In the existing wireless communication module solutions with RF test sockets or RF probes, the wear of the RF test sockets or RF probes during the production process will cause the deviation between the actual line loss and the known line loss to increase, resulting in the power of the produced wireless communication module exceeding the specified power range, reducing product quality. The line loss refers to the signal strength loss of the RF path from the wireless RF communication module in the wireless module production fixture to the tester.

[0063] In order to solve the above technical problems, in an embodiment of the present application, the actual line loss of the RF path can be determined by a reference wireless communication module, wherein the reference wireless communication module is a wireless communication module (or referred to as a reference board) whose power at each frequency point is known. Specifically, a first difference between a calibrated reference power and an actual measured power of the reference wireless communication module in a wireless module production jig at a target frequency point is obtained; if the first difference between the reference power and the actual measured power is less than a preset threshold value, the first difference is directly determined as the RF path line loss at the target frequency point; or, if the first difference between the reference power and the actual measured power is not less than a preset threshold value, the first line loss is set according to the first difference, and the second difference between the reference power and the actual measured power based on the current first line loss is repeatedly obtained to update the first line loss, and the RF path line loss at the target frequency point is determined according to the final first line loss and the second difference.

[0064] The reference wireless communication module can be used to accurately determine the RF path loss, so that when the wireless RF communication module to be calibrated is calibrated, its transmission power can be within the specified target power range, thereby improving product quality. In addition, it can be applicable to wireless communication module solutions with RF test sockets or RF probes, and can also be applicable to wireless communication module solutions without RF test sockets or RF probes, that is, the wireless communication module solution does not need to set up an RF test socket or RF probe for testing, which increases the design space of the wireless communication module and reduces the design cost of the wireless communication module. For wireless communication modules with RF test sockets or RF probes, there is no need to frequently replace the RF test sockets or RF probes after they are worn out, and only the RF path loss needs to be re-determined, thereby reducing the production cost.

[0065] The radio frequency path calibration method provided in the embodiment of the present application is applicable to Figure 2 In the application scenario shown, the application scenario includes: a wireless module production jig, a comprehensive tester, and a control device (such as a PC or other electronic device). The wireless module production jig is connected to the comprehensive tester through a radio frequency path, the comprehensive tester is connected to the control device through an instrument communication line, the control device is connected to the wireless module production jig through a module control line, and the reference wireless communication module is set in the wireless module production jig.

[0066] Among them, the wireless module production jig is a jig used to place wireless communication modules, which may have unknown line losses; the benchmark wireless communication module is a wireless communication module with known power at each frequency point; the comprehensive tester is an instrument used to read and measure the wireless performance indicators of the wireless communication module.

[0067] Among them, the executor of the RF path calibration method is a control device, which can obtain the first difference between the calibrated reference power and the measured power of the reference wireless communication module in the wireless module production fixture at the target frequency; if the first difference between the reference power and the measured power is less than the preset threshold, the first difference is directly determined as the RF path line loss at the target frequency; or, if the first difference between the reference power and the measured power is not less than the preset threshold, the first line loss is set according to the first difference, and the second difference between the reference power and the measured power based on the current first line loss is repeatedly obtained to update the first line loss, and the RF path line loss at the target frequency is determined according to the final first line loss and the second difference. Optionally, the control device can implement the above process through automated software.

[0068] After determining the RF path line loss at the target frequency, the RF path line loss at the target frequency can be written into the production calibration procedure to calibrate the wireless RF communication module to be calibrated placed in the wireless module production fixture based on the RF path line loss at the target frequency.

[0069] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. It should be noted that due to space limitations, the present application specification does not list all optional implementation methods. After reading the present application specification, those skilled in the art should be able to think that as long as the technical features do not contradict each other, any combination of technical features can constitute an optional implementation method. The same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0070] Example 1

[0071] The embodiment of the present application discloses a radio frequency path calibration method, which is applied to electronic devices such as PCs.

[0072] The following will be combined with the attached Figure 2 -Attached Figure 3 , the RF path calibration method provided in the embodiment of the present application is introduced in detail.

[0073] See also Figure 3 , is a flow chart of a radio frequency path calibration method disclosed in an embodiment of the present application. The execution subject is a control device (such as a PC or other electronic device), and the method includes the following steps:

[0074] S201. Obtain a first difference between a calibrated reference power and an actual measured power of a reference wireless communication module at a target frequency in a wireless module production jig.

[0075] In this embodiment, the reference wireless communication module may be placed in a wireless module production jig and may be controlled by a control device to send a transmission signal at a target frequency.

[0076] Among them, the reference wireless communication module is a wireless communication module with known power at each frequency point, and the power corresponding to each frequency point is a pre-calibrated power (referred to as reference power in this embodiment). The reference power corresponding to each frequency point of the reference wireless communication module can be pre-stored in the memory of the control device.

[0077] After the reference wireless communication module sends out a transmission signal at the target frequency, the measured power at the target frequency can be measured by the comprehensive tester. Due to the existence of line loss, that is, there is a signal strength loss in the RF path from the wireless RF communication module in the wireless module production fixture to the tester, including line loss in the fixture, wire, instrument, etc., there is a certain difference between the reference power calibrated at the target frequency and the measured power for the reference wireless communication module. In this embodiment, the difference between the reference power and the measured power at the target frequency can be obtained, which is recorded as the first difference.

[0078] Optionally, in different embodiments, after the first difference is obtained, S202 or S203 may be performed respectively according to the size of the first difference.

[0079] Specifically, in an optional embodiment, if the first difference is not less than the preset threshold, S202 is executed, and the steps are as follows:

[0080] S202. If the first difference between the reference power and the measured power is not less than a preset threshold, the first line loss is set according to the first difference, and the second difference between the reference power and the measured power based on the current first line loss is repeatedly obtained to update the first line loss, and the RF path line loss at the target frequency is determined according to the final first line loss and the second difference.

[0081] In this embodiment, considering the nonlinear characteristics of the comprehensive tester, when the line loss is not within the range of the preset threshold, the measured power of the comprehensive tester is inaccurate. Correspondingly, when the measured power is inaccurate, the first difference between the reference power and the measured power is also inaccurate. Therefore, the first difference at this time cannot be determined as the line loss, and repeated tests are required to determine the accurate line loss. Optionally, the preset threshold can be ±0.3, of course, it can also be other values, which can be set according to actual conditions and are not limited here.

[0082] Specifically, in this embodiment, when the control device determines that the first difference is not less than a preset threshold value, the control device sets a first line loss according to the first difference, wherein the first line loss is the line loss set in the intermediate process, and is not the final determined line loss. After setting the first line loss, the control device can control the reference wireless communication module to send a transmission signal at the target frequency based on the first line loss, and the measured power at the target frequency can be measured by the comprehensive tester. When the measured power is re-detected, the reference level changes, so the accuracy of the measured power measured by the comprehensive tester is further improved; at this time, the reference level can be obtained. The second difference between the power and the measured power based on the current first line loss, the second difference at this time is the line loss that still exists after the first line loss is set, and the first line loss can be updated according to the second difference, and by updating the first line loss, re-measuring the measured power according to the current first line loss, obtaining the second difference, and then updating the first line loss, by repeating the above operations, the measured power can be made more and more accurate, and the first line loss gradually approaches the actual RF path line loss at the target frequency point. Finally, the RF path line loss at the target frequency point can be determined according to the final first line loss and the second difference.

[0083] Specifically, in an optional embodiment, if the first difference is less than a preset threshold, S203 is executed, and the steps are as follows:

[0084] S203: If a first difference between the reference power and the measured power is less than a preset threshold, directly determining the first difference as the RF path line loss at the target frequency.

[0085] In this embodiment, taking into account the nonlinear characteristics of the comprehensive tester, when the line loss is within the range of a preset threshold, the measured power of the comprehensive tester is more accurate. Correspondingly, when the measured power is more accurate, the first difference between the reference power and the measured power is also more accurate. At this time, the first difference can be determined as the line loss.

[0086] It should be noted that, since the RF path line loss at different target frequencies may be different, the above process can be performed for different target frequencies to determine the RF path line loss at different target frequencies.

[0087] Furthermore, after determining the RF path loss at the target frequency, the RF path loss at the target frequency can be written into the production calibration program, so as to calibrate the wireless RF communication module to be calibrated placed in the wireless module production fixture based on the RF path loss at the target frequency. Figure 1 The process shown is to calibrate the wireless radio frequency communication module to be calibrated, which will not be repeated here.

[0088] The RF path calibration method provided in this embodiment obtains a first difference between a calibrated reference power and an actual measured power of a reference wireless communication module in a wireless module production jig at a target frequency; optionally, if the first difference between the reference power and the actual measured power is less than a preset threshold, the first difference is directly determined as the RF path line loss at the target frequency; or, optionally, if the first difference between the reference power and the actual measured power is not less than a preset threshold, the first line loss is set according to the first difference, and the second difference between the reference power and the actual measured power based on the current first line loss is repeatedly obtained to update the first line loss, and the RF path line loss at the target frequency is determined according to the final first line loss and the second difference. The reference wireless communication module can be used to accurately determine the RF path loss, so that when the wireless RF communication module to be calibrated is calibrated, its transmission power can be within the specified target power range, thereby improving product quality. In addition, it can be applicable to wireless communication module solutions with RF test sockets or RF probes, and can also be applicable to wireless communication module solutions without RF test sockets or RF probes, that is, the wireless communication module solution does not need to set up an RF test socket or RF probe for testing, which increases the design space of the wireless communication module and reduces the design cost of the wireless communication module. For wireless communication modules with RF test sockets or RF probes, there is no need to frequently replace the RF test sockets or RF probes after they are worn out, and only the RF path loss needs to be re-determined, thereby reducing the production cost.

[0089] Example 2

[0090] See also Figure 4 , the method is as described in S202 in the above embodiment 1, repeatedly obtaining a second difference between the reference power and the measured power based on the current first line loss to update the first line loss, and determining the RF path line loss at the target frequency point according to the final first line loss and the second difference, comprising the following steps:

[0091] S301, obtaining a second difference between the reference power and the measured power based on the current first line loss, and when the second difference is not less than a preset threshold, updating the first line loss according to the second difference; repeating the above process until the second difference is less than the preset threshold;

[0092] S302: When the second difference is less than a preset threshold, obtain the sum of the current first line loss and the second difference, and determine it as the RF path line loss at the target frequency.

[0093] In this embodiment, after the control device sets the first line loss according to the first difference, it can re-detect the measured power of the benchmark wireless communication module at the target frequency point through the comprehensive tester based on the first line loss, and obtain the second difference between the benchmark power and the measured power at this time. When the second difference is not less than the preset threshold, it means that the remaining line losses except the first line loss are not within the range of the preset threshold. At this time, the measured power of the comprehensive tester is inaccurate, and the first line loss can be updated according to the second difference, that is, the first line loss is increased; then the measured power of the benchmark wireless communication module at the target frequency point is re-detected through the comprehensive tester based on the first line loss, and the second difference between the benchmark power and the measured power at this time is obtained. The above process is repeated until the second difference is less than the preset threshold.

[0094] When the second difference is less than the preset threshold, it means that except for the first line loss, the remaining line losses are within the range of the preset threshold, and the measured power of the comprehensive tester is relatively accurate. At this time, the above-mentioned repetitive process can be omitted, and the sum of the current first line loss and the second difference is obtained to determine it as the RF path line loss at the target frequency.

[0095] In the above embodiment, optionally, in S202, the first line loss is set according to the first difference, which may be specifically: the product of the first difference and the preset ratio is set as the first line loss. For example, the preset ratio may be 1 / 2, and 1 / 2 of the first difference may be set as the first line loss. Of course, the preset ratio may also be other values, which are not limited here.

[0096] Furthermore, when the second difference is not less than a preset threshold in S301, updating the first line loss according to the second difference includes:

[0097] When the second difference is not less than the preset threshold, the product of the second difference and the preset ratio is added to the first line loss to obtain an updated first line loss.

[0098] In this embodiment, when updating the first line loss, the product of the second difference and the preset ratio can be accumulated and added to the first line loss. Similarly, the preset ratio can be 1 / 2, and 1 / 2 of the second difference can be set to be accumulated and added to the first line loss. That is, when the preset ratio is 1 / 2, the process of updating the first line loss is actually a binary method, and the first line loss can be quickly updated to be close to the actual line loss through the binary method. Of course, the preset ratio can also be other values, which are not limited here.

[0099] Example 3

[0100] Based on the above embodiment, the radio frequency path calibration method is described below with a specific example:

[0101] The control device stores the calibrated reference power of each frequency point of the reference wireless communication module in the memory of the automation software; for any target frequency point, the control device can implement the above-mentioned RF path calibration method through the automation software. The specific process is as follows:

[0102] 1) The control device can control the reference wireless communication module in the wireless module production jig to send a target frequency signal through the automation software;

[0103] 2) The control device can control the comprehensive tester through the automation software to read the signal power of the target frequency point, that is, the actual measured power;

[0104] 3) The control device may calculate a first difference value through automation software according to the reference power of the reference wireless communication module at the target frequency point and the measured power of the comprehensive tester;

[0105] 4) Determine whether the first difference is less than ±0.3dBm;

[0106] 5) If the first difference is not less than ±0.3dBm, the first difference is halved and set as the first line loss and written into the automation software. On the basis of the current first line loss, the measured power is measured again (at this time, the measured power changes due to changes in line loss and reference level), and the second difference between the reference power and the current measured power is obtained. It is determined whether the second difference is less than ±0.3dBm. If the second difference is not less than ±0.3dBm, the second difference is halved and written into the automation software and added to the first line loss. The first line loss is updated, and the above process is repeated until the second difference is less than ±0.3dBm. When the second difference is less than ±0.3dBm, the second difference can be added to the current first line loss to determine the RF pass line loss at the target frequency point, and written into the production calibration software.

[0107] 6) If the first difference is less than ±0.3dBm, the first difference is determined as the RF path loss at the target frequency and written into the production calibration software.

[0108] It should be noted that this embodiment is only an example, and those skilled in the art can make reasonable changes based on this embodiment to form other optional implementation methods.
