【摘要】：傳統微波阻抗匹配技術很難對動態(tài)負載做到實時、快速、穩(wěn)定的匹配。針對這一問題,本文構建了一個能夠為動態(tài)負載提供實時快速匹配的智能阻抗調配系統。該系統將三探針檢測技術與三銷釘調配器進行集成,利用三探針檢測器實時檢測動態(tài)負載反射系數的變化,同時將檢測到的反射系數傳輸到微處理器,由微處理器進行處理,控制步進電機調節(jié)三銷釘調配器,將反射系數穩(wěn)定在工程理想值范圍內,從而實現微波系統動態(tài)負載的阻抗匹配。
[Abstract]:The traditional microwave impedance matching technique is difficult to match the dynamic load in real time, fast and stable. To solve this problem, this paper constructs an intelligent impedance deployment system which can provide real-time and fast matching for dynamic load. The system integrates the three-probe detection technology with the three-pin modulator, and uses the three-probe detector to detect the change of the dynamic load reflection coefficient in real time. At the same time, the detected reflection coefficient is transmitted to the microprocessor and processed by the microprocessor. By controlling the step motor to adjust the three-pin modulator, the reflection coefficient is stabilized in the range of engineering ideal value, thus the impedance matching of the dynamic load of microwave system is realized.
