【摘要】：传统微波阻抗匹配技术很难对动态负载做到实时、快速、稳定的匹配。针对这一问题,本文构建了一个能够为动态负载提供实时快速匹配的智能阻抗调配系统。该系统将三探针检测技术与三销钉调配器进行集成,利用三探针检测器实时检测动态负载反射系数的变化,同时将检测到的反射系数传输到微处理器,由微处理器进行处理,控制步进电机调节三销钉调配器,将反射系数稳定在工程理想值范围内,从而实现微波系统动态负载的阻抗匹配。
[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.
