[0073] It can be understood that this scheme analyzes the relevant data of S parameters, uses simulation software to carry out simulation experiments, judges the stability problem of the microwave amplifier according to the relevant data changes of the micro S parameters, sets up the microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan, and screens out the most appropriate microwave amplifier adjustment feasibility plan and microwave amplifier stability test plan through the decision tree model, uses the human-computer interaction platform to input the relevant content of the microwave amplifier stability test, queries the microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan, and displays and records the relevant information of the microwave amplifier stability test.

[0074] Reference Figure 2 As shown, the scheme for testing the stability of different types of microwave amplifiers according to the microwave amplifier stability test requirements specifically includes:

[0075] According to the requirements of microwave amplifier stability on accuracy, visualization and environmental adaptability, different test schemes are set for conventional k-Δ test method, μ test method and Smith chart test method;

[0076] In the case where the environment is relatively simple and the circuit is stable in both open circuit and short circuit, the k-Δ test method is suitable for testing the stability of the microwave amplifier.

[0077] For microwave amplifier stability tests that require more stringent and accurate tests, the μ test method is suitable;

[0078] The Smith chart test method is suitable for relatively simple environments and when the amplifier stability needs to be intuitively displayed.

[0079] According to other requirements of microwave amplifier stability test, a combined test method of the three is adopted;

[0080] According to other requirements of microwave amplifier stability test, the three combined test methods can be used, including:

[0081] According to the microwave amplifier stability test requirements, feature items using different test methods are extracted;

[0082] Based on the DS evidence theory principle, determine the weight value of a certain test method;

[0083] According to the actual situation analysis and historical data feedback, set the weight threshold for whether to adopt this test method;

[0084] By comparing the weight value of a test method calculated by the DS evidence theory with the weight threshold of the test method, it is determined whether the calculated value is greater than the weight threshold. If so, it means that the test method is adopted, otherwise, it means that the test method is not adopted;

[0085] The DS evidence theory expression is:

[0086]

[0087] Among them, m(A) is the credibility of the Ath test method, K is the normalization constant, and m i (A i ) is the probability of using the i-th feature item of the A-th test method, and n is the number of feature items using the A-th test method.

[0088] It can be understood that the conventional microwave amplifier stability test methods include the k-Δ test method, the μ test method and the Smith chart test method, which have different advantages and disadvantages, and the test results of these three test methods can be obtained through the relevant data of the S parameters. Therefore, the DS evidence theory principle is used to input the characteristic items required for the microwave amplifier stability test on the human-computer interaction platform to determine the test method for this test, thereby ensuring the standardization and reliability of the test.

[0092] Based on the training sample set, the Gini index of different categories under the same input item is calculated, where different categories refer to: microwave amplifier type, different environmental factors and specific contents in stability test requirements;

[0093] Calculate the Gini index of a certain category based on the Gini index of different categories under the same input item;

[0094] According to the decision tree model, by inputting the relevant information of the microwave amplifier stability test, the most appropriate microwave amplifier adjustment feasibility plan and microwave amplifier stability test plan are screened;

[0095] The expression for calculating the Gini index of different categories under the same input item specifically includes:

[0098] The expression for calculating the Gini index of a certain category is:

[0099]

[0100] Wherein, Gini(D, A=i) is the Gini index of category i under the same input item A, i is the i-th category under the same input item A, D1 is the number of sample groups of the i-th category under the same input item A, D2 is the total number of remaining sample groups after removing the sample groups of the i-th category under the same input item A, Gini(D1) is the Gini index of the i-th category under the same input item A, and Gini(D2) is the total Gini index of the remaining samples after removing the i-th category under the same input item A.

[0101] It is understandable that the microwave amplifier type, different environmental factors and stability test requirements have different influences on the results of the microwave amplifier stability test. Through the analysis of the microwave amplifier type, different environmental factors and stability test requirements and the microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan in the early stage, a decision-making method with related connections is established. Therefore, through the decision tree model, by calculating the Gini coefficients of different categories of the same input item, the weight of selecting the category is determined, so as to effectively screen out the most suitable microwave amplifier adjustment feasibility plan and microwave amplifier stability test plan, which is conducive to improving the convenience and intelligence of microwave amplifier stability detection.

[0102] Further, based on the same inventive concept as the above-mentioned stability test management method for microwave power amplifiers, the present solution also proposes a stability test management system for microwave power amplifiers, comprising:

[0105] An interactive platform module is used to establish a human-computer interactive platform for querying a microwave amplifier adjustment feasibility plan and a microwave amplifier stability test plan, and displaying and recording relevant information of the microwave amplifier stability test.

[0106] The data processing module includes:

[0107] A stability adjustment unit, wherein the stability adjustment unit is used to carry out simulation experiments using simulation software, analyze the influence of different environments on S parameters, and establish a feasible adjustment plan for the microwave amplifier;

[0109] A scheme screening unit is used to screen the most suitable microwave amplifier adjustment feasibility scheme and microwave amplifier stability test scheme based on a decision tree model.

[0110] In summary, the advantages of the present invention are: by analyzing the relevant data of the S parameters, judging the stability problem of the microwave amplifier according to the change of the relevant data of the micro S parameters, setting the microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan, and screening out the most suitable microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan through a decision tree model, using a human-computer interaction platform to input the relevant content of the microwave amplifier stability test, querying the microwave amplifier adjustment feasibility plan and the microwave amplifier stability test plan, and displaying and recording the relevant information of the microwave amplifier stability test, thereby effectively improving the efficiency of the microwave amplifier stability test, and greatly improving the intelligence and convenience of the test.
