Design of Microwave Transmission Line Modular Experimental System Based on Visualization Teaching
According to the"field-to-circuit"analysis method in microwave transmission line theory,a modular experimental teaching system of microwave transmission line is designed based on the lumped parameter equivalent circuit.This system aims to enhance students'understanding of the fundamental principles and operational characteristics of microwave transmission lines.The system employs low-frequency circuit components for modular design and utilizes two sets of LED lights with different colors to visually demonstrate various signal states within the transmission line.This intuitive representation allows students to grasp the signal transmission process effectively and increase their interest in conducting experiments.Furthermore,the module incorporates a modular interlocking interface,facilitating component replacement and system debugging,while also enables further expansion into designing experiments involving complex components such as matching circuits and power division circuits.These features are conducive to fostering students'spirit of exploration,practical abilities,and overall educational advancement.
