Description

Technical Field

[0001] The present invention relates to the field of filtering technology, and in particular to a method and system for evaluating the performance of an SSPP transmission line coupling filter based on coupling branches. Background Art

[0002] SSPP transmission line coupled filter is a filtering technology based on a new transmission line structure with excellent performance and is widely used in high-frequency microwave circuits. The origin of SSPP technology can be traced back to the 1980s, when researchers began to explore integrated and miniaturized filtering structures based on traditional microstrip lines and coplanar waveguides. With the advancement of electronic technology and materials science, SSPP transmission lines have been able to achieve higher performance in the microwave frequency band, especially in reducing insertion loss, improving out-of-band suppression, and increasing filter adjustability. In recent years, SSPP transmission line coupled filters have gradually been closely integrated with high-frequency application requirements such as 5G communications and radar systems, providing these applications with more efficient and reliable signal processing capabilities, further promoting the development and application of SSPP filtering technology in RF and microwave systems.

[0003] 1. Limited test accuracy: When evaluating the performance of SSPP filters, existing systems are limited by the resolution of the test instrument. Especially in high-frequency signal transmission, it is difficult to accurately capture small insertion losses and weak coupling effects, resulting in insufficient accuracy of performance evaluation results.

[0004] 2. Low debugging efficiency: Traditional evaluation systems are cumbersome when optimizing and debugging SSPP filters. They rely on manual adjustments and lack automated testing and intelligent analysis methods, which makes parameter optimization efficiency low and difficult to meet the needs of rapid testing.

[0005] 3. Insufficient depth of data analysis: The current system lacks intelligent analysis methods for evaluation data and cannot deeply explore the correlation between multiple parameters, which limits the comprehensive evaluation of the overall performance of the SSPP filter and makes it difficult to provide detailed optimization suggestions. Summary of the invention

[0006] The present invention aims to provide a method and system for evaluating the performance of a SSPP transmission line coupled filter based on coupling branches, so as to solve the above-mentioned problems.

[0007] The present invention is achieved through the following technical solutions:

[0013] The intelligent optimization evaluation module is used to pre-set a performance evaluation threshold Pv, and compare and evaluate the performance evaluation threshold Pv with the signal attenuation difference coefficient Szxs. By associating the coupling influence coefficient Yxcs with the signal attenuation difference coefficient Szxs, the comprehensive performance evaluation index Pfci of the SSPP transmission line coupling filter is obtained by fitting. The comprehensive performance evaluation index Pfci is combined with the performance evaluation threshold Pv for another evaluation, and the performance and stability of the SSPP transmission line coupling filter are comprehensively analyzed, and targeted optimization suggestions are provided.

[0014] Preferably, after identifying the abnormal area in the signal transmission, the signal acquisition module divides and processes the stress distribution state of the coupled branch structure according to the signal intensity change pattern in the abnormal area, and obtains several groups of coupled branch stress concentration areas; finally, the coupled branch stress concentration areas are marked and layered.

[0015] Preferably, the coupling parameter monitoring module is used to sequentially collect relevant signal parameters and coupling effect related data for the marked coupling branch stress concentration area; then, the relevant signal parameters and coupling effect related data are classified and integrated, and the monitoring is further extended to the connection nodes of each level of the SSPP transmission line coupling filter to collect the state related data of the connection nodes at each level; finally, the relevant signal parameters and coupling effect data are summarized with the state related data of the connection nodes at each level to construct a complete performance evaluation data set.

[0016] Preferably, the data processing module is used to systematically process relevant data information in the performance evaluation data set, including data cleaning, feature extraction and standardization; then, based on the characteristics of the signal data information, important feature parameters are extracted, and the important feature parameters include signal amplitude change rate and frequency response characteristics; finally, the extracted important feature parameters are standardized according to the dimensionless processing technology, so that data of different units and magnitudes are unified, and a standardized performance evaluation data set is constructed.

[0017] Preferably, the filtering performance analysis module includes a signal attenuation difference coefficient calculation unit, a condition change impact calculation unit and a coupling effect evaluation unit;

[0018] The signal attenuation difference coefficient calculation unit is used to construct the signal attenuation difference coefficient Szxs before and after the installation of the SSPP transmission line coupling filter based on the relevant signal parameters of the coupling branch stress concentration area in the performance evaluation data set. The specific calculation formula is as follows:

[0026] In the formula, ln represents the natural logarithm with a constant as the base.

[0027] Preferably, the coupling effect evaluation unit is used to comprehensively evaluate the generated coupling influence coefficient Yxcs, and compare and analyze the coupling influence coefficient Yxcs with the preset influence threshold Q. The specific evaluation content is as follows:

[0028] If the coupling influence coefficient Yxcs>influence threshold Q, it indicates that the change in the environmental conditions of the coupling branch has an abnormal effect on the signal attenuation difference coefficient, and causes the filter performance to deviate from the preset standard; at this time, the system immediately issues an early warning instruction to prompt, and further analyzes whether the specific influencing factors in the abnormal environment have exceeded the safety tolerance range, and then decides whether parameter adjustment or calibration is required; finally, further analysis is performed to determine whether the performance change of the filter in a specific environment meets the debugging conditions;

[0029] If the coupling influence coefficient Yxcs≤influence threshold Q, it indicates that the environmental condition change of the coupling branch has a normal impact on the signal attenuation difference coefficient and meets the debugging conditions. At this time, the system does not issue a warning command and continues to maintain normal operation.

[0031] The performance evaluation unit compares and evaluates the preset performance evaluation threshold Pv with the signal attenuation difference coefficient Szxs, and the specific evaluation content is as follows:

[0032] If the signal attenuation difference coefficient Szxs ≤ the performance evaluation threshold Pv, it means that the signal attenuation of the SSPP transmission line coupling filter meets the expected standard and the performance status is normal. At this time, the system does not need to be adjusted and directly enters the next evaluation process;

[0033] If the signal attenuation difference coefficient Szxs> the performance evaluation threshold Pv, it indicates that the signal attenuation of the SSPP transmission line coupling filter does not meet the expected standard and the performance status is abnormal. At this time, the system conducts an in-depth analysis to determine the value and trend of the excess part to determine whether it is caused by environmental factors, coupling structure problems, or inherent deviations in the filter parameters. Based on the in-depth analysis results, the system issues performance adjustment suggestions, including adjusting the design or use conditions of the SSPP transmission line coupling filter.

[0034] Preferably, the optimization analysis unit calculates and obtains the comprehensive performance evaluation index Pfci of the SSPP transmission line coupling filter by the following formula:

[0035]

[0036] Then, we conduct another evaluation by combining the comprehensive performance evaluation index Pfci and the performance evaluation threshold Pv. The specific evaluation contents are as follows:

[0037] If the comprehensive performance evaluation index Pfci ≤ the performance evaluation threshold Pv, it indicates that the performance and stability of the SSPP transmission line coupling filter under the current conditions are in line with expectations and no further intervention or adjustment is required;

[0038] If the comprehensive performance evaluation index Pfci>performance evaluation threshold Pv, it indicates that the performance and stability of the SSPP transmission line coupling filter under the current conditions do not meet expectations, that is, there is an abnormality, which means that the signal transmission quality or coupling conditions of the filter are deviated;
