The same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below in conjunction with the accompanying drawings.

Example 1

The embodiment of the present application discloses a method for calibrating a radio frequency path, and the method is applied to electronic equipment such as a PC.

The method for calibrating the radio frequency path provided by the embodiment of the present application will be described in detail below with reference to accompanying drawings 2 to 3 .

Please refer to FIG. 3 , which is a flowchart of a method for calibrating a radio frequency path disclosed in an embodiment of the present application. Its executive subject is a control device (such as a PC or other electronic equipment), and the method includes the following steps:

S201. Obtain a first difference between the calibrated reference power and the measured power of the reference wireless communication module in the wireless module production jig at the target frequency point.

In this embodiment, the reference wireless communication module can be placed in the wireless module production fixture, which can be controlled by the control device to send out the transmission signal at the target frequency point.

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 the frequency point can be pre-stored in the memory of the control device.

After the reference wireless communication module sends a transmission signal at the target frequency point, the actual power at the target frequency point can be measured by the comprehensive tester. Due to the existence of line loss, that is, there is signal strength loss in the radio frequency path between the radio frequency communication module in the wireless module production fixture and the tester, including fixtures, wires, instruments, etc. For the wireless communication module, there is a certain difference between the reference power calibrated at the target frequency point and the measured power. In this embodiment, the difference between the reference power at the target frequency point and the measured power can be obtained, which is recorded as the first difference.

Optionally, in different embodiments, after the first difference is acquired, S202 or S203 may be executed respectively according to the magnitude of the first difference.

Specifically, in an optional embodiment, if the first difference is not less than the preset threshold, then execute S202, and the steps are as follows:

S202. If the first difference between the reference power and the measured power is not less than the preset threshold, set the first line loss according to the first difference, and repeatedly obtain the difference between the reference power and the measured power based on the current first line loss. The second difference value is used to update the first line loss, and the radio frequency path line loss at the target frequency is determined according to the final first line loss and the second difference value.

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 reference power The first difference between the measured power and the measured power is also inaccurate, so the first difference at this time cannot be determined as the line loss, and repeated tests are required to determine the accurate line loss. Wherein, optionally, the preset threshold value may be ±0.3, and of course it may also be other values, which may be set according to actual conditions, and there is no limitation here.

Specifically, in this embodiment, when the control device determines that the first difference is not less than the preset threshold, the control device sets the first line loss according to the first difference, where the first line loss is the set line loss in the middle process The loss 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 point based on the first line loss, which can be measured by the comprehensive tester. The measured power at the frequency point, the reference level changes when the measured power is re-detected, so the accuracy of the measured power measured by the comprehensive tester is further improved; at this time, the difference between the reference power and the measured power based on the current first line loss can be obtained. The second difference between, the second difference at this time is the line loss that still exists after setting the first line loss, the first line loss can be updated according to the second difference, and by updating the first line loss, According to the measured power re-measured by the current first line loss, obtain the second difference, and then update the first righteous line loss. By repeating the above operations, the measured power will become more and more accurate, and the first line loss will gradually approach the target frequency. The real radio frequency channel line loss at the target frequency point, and finally the radio frequency channel line loss at the target frequency point can be determined according to the final first line loss and the second difference.

Specifically, in an optional embodiment, if the first difference is less than the preset threshold, then execute S203, the steps of which are as follows:

S203. If the first difference between the reference power and the measured power is smaller than the preset threshold, directly determine the first difference as the radio frequency path line loss at the target frequency point.

In this embodiment, considering the nonlinear characteristics of the comprehensive tester, when the line loss is within the range of the preset threshold, the measured power of the comprehensive tester is relatively accurate. Correspondingly, when the measured power is relatively accurate, the reference power and The first difference between the measured powers is also more accurate, and at this time the first difference can be determined as the line loss.

It should be noted that since the radio frequency path line loss at different target frequency points may be different, the above process may be performed on different target frequency points to determine the radio frequency path line loss at different target frequency points.

Further, after determining the line loss of the radio frequency path under the target frequency point, the line loss of the radio frequency path under the target frequency point can be written into the production calibration program, so as to place the radio frequency path line loss pair in the wireless mode based on the target frequency point Calibrate the wireless radio frequency communication module to be calibrated in the production fixture, that is, calibrate the wireless radio frequency communication module to be calibrated through the process shown in FIG. 1 , which will not be repeated here.

The radio frequency path calibration method provided in this embodiment obtains 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 point; optionally, if The first difference between the reference power and the measured power is less than the preset threshold, then directly determine the first difference as the radio frequency path line loss at the target frequency point; or, optionally, if the reference power and the measured power The first difference between them is not less than the preset threshold, then set the first line loss according to the first difference, and repeatedly acquire the second difference between the reference power and the measured power based on the current first line loss to update the first line loss First line loss, determining the radio frequency path line loss at the target frequency point according to the final first line loss and the second difference. The reference wireless communication module can accurately determine the line loss of the radio frequency channel, and then when the wireless radio frequency communication module to be calibrated is calibrated, its transmission power can reach the specified target power range to improve product quality; in addition, it can be applied to The wireless communication module solution with RF test socket or RF probe is also applicable to the wireless communication module solution without RF test socket or RF probe, that is, the wireless communication module solution does not need to be set for RF testing socket or RF probe, which increases the design space of wireless communication modules and reduces the design cost of wireless communication modules; for wireless communication modules with RF test sockets or RF probes, after the RF test sockets or RF probes are worn No need for frequent replacement, only need to re-determine the line loss of the radio frequency path, which reduces the generation cost.

Example 2

Referring to FIG. 4 , the second difference between the reference power and the measured power based on the current first line loss is repeatedly obtained as described in S202 in the above embodiment 1 to update the first line loss. According to the final first line loss and The second difference determines the radio frequency path line loss under the target frequency point, comprising the following steps:

S301. Obtain the 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 the preset threshold, update the first line loss according to the second difference; repeat the above process, until the second difference is smaller than the preset threshold;

S302. When the second difference is smaller than the preset threshold, obtain the sum of the current first line loss and the second difference, and determine it as the radio frequency path line loss at the target frequency point.

In this embodiment, after the control device sets the first line loss according to the first difference, it can re-detect the actual power of the reference wireless communication module at the target frequency point through the comprehensive tester based on the first line loss to obtain the reference power The second difference between the measured 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 loss is not within the range of the preset threshold except the first line loss, and the comprehensive tester at this time If the measured power is inaccurate, the first line loss can be updated according to the second difference, that is, the first line loss can be increased; then based on the first line loss, the comprehensive tester can re-test the reference wireless communication module at the target frequency point Measured power, obtaining a second difference between the reference power and the measured power at this time, and repeating the above process until the second difference is smaller than the preset threshold.

When the second difference is less than the preset threshold value, it means that the remaining line loss except the first line loss is within the range of the preset threshold value, and the actual power measured by the comprehensive measuring instrument is relatively accurate, then the above-mentioned repeating process may not be continued at this time, Obtain the sum of the current first line loss and the second difference, and determine it as the radio frequency path line loss at the target frequency point.

In the above embodiment, optionally, in S202, the first line loss is set according to the first difference, which may specifically be: setting the product of the first difference and a preset ratio as the first line loss. For example, the preset ratio may be 1/2, then 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.

Further, in S301, when the second difference is not less than the preset threshold, updating the first line loss according to the second difference includes:

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.

In this embodiment, when updating the first line loss, the product of the second difference and the preset ratio can be added to the first line loss. Similarly, the preset ratio can be 1/2, and the second The 1/2 setting of the difference is 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 dichotomy method, through which the first line loss can be quickly The loss is updated to approximate the actual line loss. Of course, the preset ratio may also be other values, which are not limited here.

4) Judging whether the first difference is less than ±0.3dBm;

5) The first difference is not less than ±0.3dBm, then the first difference is halved, set as the first line loss and written into the automation software, and the measured power is measured again on the basis of the current first line loss (at this time, the measured power is due to Line loss and reference level changes), obtain the second difference between the reference power and the current measured power, and judge whether the second difference is less than ±0.3dBm, if the second difference is not less than ±0.3dBm, then set 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, it can be Add the second difference to the current first line loss, determine it as the RF channel line loss at the target frequency point, and write it into the production calibration software;

6) If the first difference is less than ±0.3dBm, then determine the first difference as the RF channel line loss at the target frequency point and write it into the production calibration software.
