[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.
