It should be noted that the present specification is not intended to exhaust all alternative embodiments for the sake of brevity, and it should be understood by those skilled in the art after reading the present specification that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent. Details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.

Example 1

The embodiment of the application discloses a radio frequency path calibration method which is applied to electronic equipment such as a PC (personal computer).

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

Fig. 3 is a flowchart illustrating a method for calibrating a radio frequency channel according to an embodiment of the present application. The execution main body is a control device (such as a PC or other electronic devices), and the method comprises the following steps:

s201, obtaining a first difference value between a calibrated reference power and an actual measurement power of a reference wireless communication module in a wireless module production jig under a target frequency point.

In this embodiment, the reference wireless communication module can be placed in the wireless module production jig, and can be controlled by the control device to transmit signals at the target frequency point.

The reference wireless communication module is a wireless communication module with known power at each frequency point, the power corresponding to each frequency point is a pre-calibrated power (referred to as reference power in this embodiment), and 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.

After the reference wireless communication module transmits signals at the target frequency point, the integrated tester can measure the actual measurement power at the target frequency point. Because the line loss exists, that is, there is signal intensity loss in the radio frequency path from the wireless radio frequency communication module in the wireless module production jig to the tester, and there is line loss in all anchor clamps, wires, instruments, etc., therefore, for the benchmark wireless communication module, there is a certain difference between the benchmark power and the actual measurement power calibrated under the target frequency point, and in this embodiment, the difference between the benchmark power and the actual measurement power under the target frequency point can be obtained and recorded as a first difference.

Optionally, in different embodiments, after obtaining the first difference, S202 or S203 may be respectively performed according to a magnitude of the first difference.

Specifically, in an optional embodiment, if the first difference is not smaller than the preset threshold, step S202 is executed, which includes the following steps:

s202, if a first difference between the reference power and the actually measured power is not smaller than a preset threshold, setting a first line loss according to the first difference, repeatedly obtaining a second difference between the reference power and the actually measured power based on the current first line loss to update the first line loss, and determining the radio frequency access line loss under the target frequency point according to the final first line loss and the second difference.

In this embodiment, in consideration of the nonlinear characteristic of the integrated tester, when the line loss is not within the range of the preset threshold, the measured power of the integrated tester is inaccurate, and accordingly, the first difference between the reference power and the measured power is also inaccurate under the condition that the measured power is inaccurate, so that the first difference at this time cannot be determined as the line loss, and the accurate line loss needs to be determined through repeated tests. Optionally, the preset threshold may be ± 0.3, and of course, may be other values, and may be set according to an actual situation, which is not limited herein.

Specifically, in this embodiment, when the control device determines that the first difference is not less than the preset threshold, the control device sets a first line loss according to the first difference, where the first line loss is a set line loss in an intermediate process and is not a final determined line loss, after the first line loss is set, the control device may control the reference wireless communication module to transmit a transmission signal at a target frequency point based on the first line loss, may measure, by using the integrated meter, an actual measurement power at the target frequency point, and when the actual measurement power is re-detected, a reference level changes, so that accuracy of the actual measurement power measured by the integrated meter is further improved; and at the moment, a second difference value between the reference power and the actually measured power based on the current first line loss can be obtained, the second difference value is the line loss still existing after the first line loss is set, the first line loss can be updated according to the second difference value, the first line loss is updated, the actually measured power re-measured according to the current first line loss is obtained, the second difference value is obtained, the first line loss is updated, the actually measured power is more and more accurate by repeating the operations, the first line loss is gradually close to the real radio frequency path line loss under the target frequency point, and finally the radio frequency path line loss under the target frequency point can be determined according to the final first line loss and the second difference value.

Specifically, in an optional embodiment, if the first difference is smaller than the preset threshold, step S203 is executed, which includes the following steps:

s203, if the first difference between the reference power and the actually measured power is smaller than a preset threshold, directly determining the first difference as the radio frequency channel path loss under the target frequency point.

In this embodiment, considering the nonlinear characteristic of the integrated tester, when the line loss is within the range of the preset threshold, the measured power of the integrated tester is relatively accurate, and correspondingly, under the condition that the measured power is relatively accurate, the first difference between the reference power and the measured power 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 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 loss at different target frequency points.

Further, after determining the radio frequency path loss at the target frequency point, the radio frequency path loss at the target frequency point may be written into a production calibration program, so as to calibrate the to-be-calibrated wireless radio frequency communication module placed in the wireless module production jig based on the radio frequency path loss at the target frequency point, that is, calibrate the to-be-calibrated wireless radio frequency communication module through the process shown in fig. 1, which is not described herein again.

In the radio frequency path calibration method provided by this embodiment, a first difference between a calibrated reference power and an actual measurement power of a reference wireless communication module in a wireless module production jig at a target frequency point is obtained; optionally, if a first difference between the reference power and the measured power is smaller than a preset threshold, directly determining the first difference as the radio frequency channel path loss at the target frequency point; or, optionally, if a first difference between the reference power and the actual measurement power is not less than a preset threshold, setting a first line loss according to the first difference, repeatedly obtaining a second difference between the reference power and the actual measurement power based on the current first line loss to update the first line loss, and determining the radio frequency access line loss at the target frequency point according to the final first line loss and the second difference. The radio frequency communication module can accurately determine the path loss of the radio frequency channel through the reference wireless communication module, so that the transmitting power of the radio frequency communication module to be calibrated reaches the range of the specified target power when the radio frequency communication module to be calibrated is calibrated, and the product quality is improved; in addition, the method is suitable for a wireless communication module scheme with a radio frequency test seat or a radio frequency probe, and also suitable for a wireless communication module scheme without the radio frequency test seat or the radio frequency probe, namely the wireless communication module scheme does not need to be provided with the radio frequency test seat or the radio frequency probe for testing, so that the design space of the wireless communication module is enlarged, and the design cost of the wireless communication module is reduced; for the wireless communication module with the radio frequency test seat or the radio frequency probe, the radio frequency test seat or the radio frequency probe is not required to be frequently replaced after being worn, only the radio frequency pass line loss needs to be determined again, and the generation cost is reduced.

Example 2

Referring to fig. 4, for repeatedly obtaining a second difference between the reference power and the measured power based on the current first line loss in S202 in embodiment 1 to update the first line loss, determining the radio frequency channel line loss at the target frequency point according to the final first line loss and the second difference, the method includes the following steps:

s301, obtaining a second difference value between the reference power and the actual measurement power based on the current first line loss, and updating the first line loss according to the second difference value when the second difference value is not smaller than a preset threshold value; repeating the process until the second difference value is smaller than the preset threshold value;

and S302, when the second difference is smaller than a preset threshold, obtaining the sum of the current first line loss and the second difference, and determining the sum as the radio frequency channel line loss under the target frequency point.

In this embodiment, after setting the first line loss according to the first difference, the control device may detect the actual measurement power of the reference wireless communication module at the target frequency point again through the integrated tester based on the first line loss, obtain a second difference between the reference power and the actual measurement power at this time, and when the second difference is not less than the preset threshold, it indicates that the remaining line loss except the first line loss is not within the range of the preset threshold, and the actual measurement power of the integrated tester is inaccurate at this time, and may update the first line loss according to the second difference, that is, increase the first line loss; and then, re-detecting the actual measurement power of the reference wireless communication module under the target frequency point through the integrated tester based on the first line loss, acquiring a second difference value between the reference power and the actual measurement power at the moment, and repeating the process until the second difference value is smaller than a preset threshold value.

And when the second difference is smaller than the preset threshold, the measured power of the comprehensive tester is more accurate, and at this moment, the repeated process is not continued, the sum of the current first line loss and the second difference is obtained, and the sum is determined as the radio frequency channel line loss under the target frequency point.

In the above embodiment, optionally, the setting the first line loss according to the first difference in S202 may specifically be: and setting the product of the first difference value and the preset proportion as a 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 be other values, and is not limited herein.

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

In this embodiment, when the first line loss is updated, the product of the second difference and the preset ratio may be added to the first line loss, similarly, the preset ratio may be 1/2, and then 1/2 of the second difference may be 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 bisection, and the first line loss may be quickly updated to approach the actual line loss through the bisection. Of course, the preset ratio may be other values, and is not limited herein.
