电流加权电调谐静磁表面波带通滤波器频率响应的理论研究

The Analysis Design and Synthesis of a Tunable Magnetostatic Surface Wave Bandpass Filter Based on Current Weighting Transducer Array

完成了电流加权电调谐静磁表面波（ＭＳＳＷ）带通滤波器全部工作过程的理论 分析，实现了这种滤波器的ＣＡＤ。给出了几种典型结构频率响应的理论计算结果，并 与实验结果进行了比较，二者符合较好。

The tunable MSSW bandpass filter based on current weighting is a device of new type. It shows the potentiality in signal processing system and finds farvour in related expert's eyes. The theoretical analysis of MSSW-CWF is accomplished and the CAD with such filter is realized. The calculated results of some typical construction are presented and compared with experimental data.
