The same or similar concepts or processes may not be described in detail 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 channel calibration method which is applied to electronic equipment such as a PC (personal computer).
The following describes in detail the radio frequency path calibration method according to the embodiment of the present application with reference to fig. 2 to fig. 3.
Fig. 3 is a flowchart of a radio frequency path calibration method according to an embodiment of the present application. The execution subject is a control device (such as a PC or other electronic device), and the method comprises the following steps:
S201, obtaining a first difference value between calibrated reference power and 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 may be placed in the wireless module production jig, and may be controlled by the control device to send out the transmission signal at the target frequency point.
The reference wireless communication module is a wireless communication module with known power under each frequency point, the corresponding power of each frequency point is a pre-calibrated power (referred to as reference power in this embodiment), and the corresponding reference power of 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 sends out a transmitting signal under the target frequency point, the comprehensive tester can measure the actual measurement power under the target frequency point. Because the line loss exists, that is, the signal strength loss exists in the radio frequency channel from the radio frequency communication module in the wireless module production jig to the tester, including the line loss exists in the clamp, the wire rod, the instrument and the like, for the reference wireless communication module, a certain difference exists between the reference power calibrated under the target frequency point and the actually measured power, and in the embodiment, the difference between the reference power and the actually measured power under the target frequency point can be obtained and recorded as the first difference.
Alternatively, in different embodiments, after the first difference is obtained, S202 or S203 may be performed according to the magnitude of the first difference, respectively.
Specifically, in an alternative embodiment, if the first difference is not less than the preset threshold, step S202 is performed, which includes the following steps:
S202, if the first difference value between the reference power and the actually measured power is not smaller than a preset threshold value, setting a first line loss according to the first difference value, repeatedly obtaining a second difference value 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 path line loss under the target frequency point according to the final first line loss and the second difference value.
In this embodiment, considering the nonlinear characteristic 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, and correspondingly, under the condition that the measured power is inaccurate, the first difference between the reference power and the measured power is also inaccurate, so that the first difference at this time cannot be determined as the line loss, and further, the accurate line loss needs to be determined through repeated tests. Optionally, the preset threshold may be ±0.3, or of course, may be other values, and may be set according to practical situations, 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 line loss set in the middle process and is not a final determined line loss, after the first line loss is set, the control device may send a transmission signal under the target frequency point based on the first line loss control reference wireless communication module, the comprehensive tester measures the actual measurement power under the target frequency point, and changes the reference level when the actual measurement power is redetected, so that the accuracy of the actual measurement power measured by the comprehensive tester is further improved, at this time, a second difference between the reference power and the actual measurement power based on the current first line loss may be obtained, where the second difference is a line loss still existing after the first line loss is set, and the first line loss may be updated according to the second difference, and by updating the first line loss, the actual measurement power measured according to the current first line loss is redetected, the second difference may be obtained, and the first sense line loss may be updated, by repeating the operations described above, so that the accuracy of the first line loss may be gradually and the final radio frequency loss may be determined to be gradually close to the actual measurement power under the target frequency point.
Specifically, in an alternative embodiment, if the first difference is smaller than the preset threshold, step S203 is performed, which includes the following steps:
And S203, if the first difference value between the reference power and the actually measured power is smaller than a preset threshold value, directly determining the first difference value as the radio frequency path line loss under the target frequency point.
In this embodiment, considering the nonlinear characteristic of the comprehensive tester, when the line loss is within the range of the preset threshold, the measured power of the comprehensive tester is more accurate, and correspondingly, under the condition that the measured power is more accurate, the first difference between the reference power and the measured power is more accurate, and at this time, the first difference can be determined as the line loss.
It should be noted that, because the radio frequency path line loss may be different at different target frequency points, the above process may be performed for different target frequency points, so as to determine the radio frequency path line loss at different target frequency points.
Further, after the radio frequency path line loss under the target frequency point is determined, the radio frequency path line loss under the target frequency point may be written into the production calibration program, so as to calibrate the to-be-calibrated radio frequency communication module placed in the wireless module production jig based on the radio frequency path line loss under the target frequency point, that is, calibrate the to-be-calibrated radio frequency communication module through the process shown in fig. 1, which is not described herein again.
The radio frequency path calibration method comprises the steps of obtaining a first difference value between calibrated reference power and actual measurement power of a reference wireless communication module in a wireless module production jig under a target frequency point, optionally, directly determining the first difference value as radio frequency path line loss under the target frequency point if the first difference value between the reference power and the actual measurement power is smaller than a preset threshold value, or optionally, setting the first line loss according to the first difference value if the first difference value between the reference power and the actual measurement power is not smaller than the preset threshold value, repeatedly obtaining a second difference value 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 path line loss under the target frequency point according to the final first line loss and the second difference value. The radio frequency communication module can accurately determine the radio frequency path line loss, so that the transmitting power of the radio frequency communication module to be calibrated reaches the specified target power range when the radio frequency communication module to be calibrated is calibrated, the product quality is improved, the radio frequency communication module can be suitable for a radio frequency communication module scheme with a radio frequency test seat or a radio frequency probe, and also suitable for a radio frequency communication module scheme without the radio frequency test seat or the radio frequency probe, namely, the radio frequency communication module scheme does not need to be provided with the radio frequency test seat or the radio frequency probe, the design space of the radio frequency communication module is enlarged, the design cost of the radio frequency communication module is reduced, the radio frequency path line loss of the radio frequency communication module with the radio frequency test seat or the radio frequency probe does not need to be replaced frequently after the radio frequency test seat or the radio frequency probe is worn, and the generation cost is reduced.
Example 2
Referring to fig. 4, for updating the first line loss by repeating the second difference between the reference power obtained in step S202 and the measured power based on the current first line loss in embodiment 1, the radio frequency path line loss at the target frequency point is determined according to the final first line loss and the second difference, which includes the following steps:
S301, acquiring 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;
And S302, when the second difference value is smaller than a preset threshold value, acquiring the sum of the current first line loss and the second difference value, and determining the sum as the radio frequency path line loss under the target frequency point.
In this embodiment, after the first line loss is set according to the first difference, the control device may re-detect, by the comprehensive tester, the actually measured power of the reference wireless communication module at the target frequency point based on the first line loss, obtain a second difference between the reference power and the actually measured power at the time, and when the second difference is not less than the preset threshold, it indicates that the remaining line loss is not within the range of the preset threshold except for the first line loss, at the time, the actually measured power of the comprehensive tester is inaccurate, and the first line loss may be updated according to the second difference, that is, the first line loss is increased, and then re-detect, by the comprehensive tester, the actually measured power of the reference wireless communication module at the target frequency point based on the first line loss, obtain a second difference between the reference power and the actually measured power at the time, and repeat the above process until the second difference is less than the preset threshold.
When the second difference value is smaller than the preset threshold value, the fact that the residual line loss except the first line loss is in the range of the preset threshold value is indicated, the measured power of the comprehensive tester is accurate, the repeated process can be omitted at the moment, the sum of the current first line loss and the second difference value is obtained, and the sum is determined to be the radio frequency path line loss under the target frequency point.
In the above embodiment, optionally, the first line loss is set according to the first difference in S202, and specifically, the product of the first difference and the preset ratio may be set as the first line loss. For example, the preset ratio may be 1/2, and then 1/2 of the first difference may be set as the first line loss. Of course, the preset ratio may be other values, and the present invention is not limited thereto.
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:
and when the second difference value is not smaller than the preset threshold value, accumulating the product of the second difference value and the preset proportion to the first line loss to obtain the updated first line loss.
In this embodiment, when the first line loss is updated, the product of the second difference and the preset ratio may be accumulated to the first line loss, and similarly, the preset ratio may be 1/2, and then the 1/2 setting of the second difference may be accumulated 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 bisection method, and the first line loss may be quickly updated to be close to the actual line loss by the bisection method. Of course, the preset ratio may be other values, and the present invention is not limited thereto.
