Abstract

The temperature properties of the incredible high performance (I.H.P.) structures on a multilayer lithium tantalate/silicon dioxide film/silicon substrate have been studied; these structures are used to improve the characteristics of devices on surface acoustic waves. Test structures have been simulated by the finite-element method in the COMSOL software and the temperature coefficient of frequency has been calculated. The calculated transfer coefficients of a resonator filter on a conventional single-crystal 36°YX-cut lithium tantalate substrate and an I.H.P. filter are compared at different temperatures. It is shown that the temperature coefficient of frequency can be minimized by fitting the thicknesses of the substrate layers. A comparison shows that the results obtained are in good agreement with the known data. The practical importance is that the simulation results and calculated parameters can be used for designing devices of different classes based on multilayer substrates (including those with I.H.P. structures).

研究 I.H.P. 结构的温度特性及其在表面声波滤波器中的应用
研究了多层钽酸锂/二氧化硅薄膜/硅衬底上不可思议的高性能(I.H.P.)结构的温度特性;这些结构用于改善表面声波器件的特性。测试结构通过 COMSOL 软件中的有限元法进行了模拟,并计算了频率的温度系数。比较了传统单晶 36°YX 切割钽酸锂基底上的谐振器滤波器和工频滤波器在不同温度下的计算传递系数。结果表明,通过对衬底层的厚度进行拟合,可以将频率的温度系数降至最低。比较结果表明,模拟结果与已知数据十分吻合。模拟结果和计算参数可用于设计基于多层衬底(包括具有 I.H.P. 结构的衬底)的不同类型的器件,这一点具有重要的实际意义。
