分析锥型技能器的基本原则是把换能器沿孔径方向划分成足够多的通道来进行近似，设计制作的关键是加权技术和数据处理技巧。由于SPUDT的特性，把EWC型的SPUDT引入到锥型换能器对制作宽带、低损耗器件是十分有用的；我们在Y128°LN基片上采用一般型和SPUDT型锥型换能器制作了相对带宽约15％的声表面波滤波器，一个换能器采用“块加权”，另一个换能器采用抽指加权。文中给出了两种器件的实验结果，SPUDT型声表面波滤波器的插损仅7．5dB。
The basic principle of analyzing cone-typed skill is to divide the transducer along the aperture direction into enough channels for approximation. The key of the design is the weighted technique and data processing technique. Due to the characteristics of SPUDT, the introduction of EWC-type SPUDT into tapered transducers is very useful for making broadband, low-loss devices. We used a general-purpose and SPUDT-type cone transducer on a Y128 ° LN substrate to make a relative Bandwidth of about 15% of the surface acoustic wave filter, a transducer with “block weighting” and the other with finger-weighted. The experimental results of two devices are given in this paper. The insertion loss of SPUDT type SAW filter is only 7.5dB.
