摘要
分析了多抽头微带取样传输线的波形失真问题,根据分布参数理论和微波传输线理论,提出基于集中参数原则的等效分布电容模型和基于分布参数理论的局部补偿模型,推导出阻抗匹配计算公式和计算方法,数值模拟和电路仿真结果表明,将两种方法联合应用进行补偿,可大大降低输出波形的失真程度。
The waveforms distortion of microstrip-tapped sampling transmission line is analyzed in this paper. According to distributed parameter theory and microwave theory,the equivalent distributed capacitance model based on centralized parameter principle and the local compensation model based on distributed parameter theory are proposed,the computing formulas and methods of impedance matching are deduced.The results of numerical analysis and circuit simulation show that the distortion of output waveforms is greatly decreased by the combined use of these two methods.
