高频超声换能器的阻抗匹配研究

本文介绍了用于声学显微镜中超声换能器的阻抗匹配方法．由三个电感构成的T型结构被选作匹配网络，通过理论计算和实验调试得到了良好的匹配效果．文章的最后给出了实际的匹配结果．

篈 design for impedance matching of ultrasonic transducer used in an acoustic tnicroscope is described. A T-structure with three inductors is adopted. The near optimal design is obtained through theoretical calculation and manual adjustment. Finally, the matching results are given
