摘要
指出提高微带横截面取样速率的关键问题是传输线多容性负载阻抗匹配,根据分布参数理论和微波传输线理论,提出局部匹配模型,推导出阻抗匹配计算公式.数值模拟和电路仿真结果表明,局部补偿匹配法对不同工作频率下的多负载电容ps脉冲传输线均可进行较好的补偿,传输线上的各点取样波形失真度很小,补偿效果明显,可以提高微带横截面取样速率.
Abstract
It is pointed out that the key problem is multi-capacitive loading resistances matching for increasing microstrip-tapped sampling speed. According to distributed parameter theory and microwave transmission line theory, the partial matched model is proposed and the computing formulas for resistance matching are deduced. The results of numerical analysis and circuit simulation show that ps pulse transmission line of different operating frequency and multi-tapped capacitances can be well compensated by the partial matched method , so the distortion to every sampling waveforms of transmission line is very small , the effect of compensation is obvious and microstrip-tapped sampling speed is increased.
