本文介绍了准倾斜SPUDT与阶梯电极。使用这种换能器简化了频率为400-600 MHz的低损耗SAW滤波器的制造。为了提高滤波器的选择性，两个有效的模拟程序，即准倾斜SPUDT的电极拔出加权的程序和模拟SAW衍射对滤波器性能的影响的程序已经开发。385 MHz和450 MHz的WLAN滤波器的建模和实验结果的报告。
The paper describes quasi-slanted SPUDTs with stepped electrodes. Using such transducers simplifies the fabrication of low-loss SAW filters for frequencies 400-600 MHz. To improve filter selectivity, two efficient simulation procedures have been developed, namely, the procedure of electrode withdrawal weighting of quasi-slanted SPUDTs and the procedure of simulating the effect of SAW diffraction on filter performance. The results of modeling and experiments for 385 MHz and 450 MHz WLAN filters are reported.
