In this work, a SAW resonator is characterized in terms of admittance (-) parameters in the temperature range spanning from 0 °C to 100 °C, with the aim of highlighting how its physical properties are affected by the temperature change. A lumped-element equivalent-circuit model is used to represent the device under test at the considered temperature conditions and a parameters extraction process based on a Lorentzian fitting is developed for the determination of the equivalent-circuit elements in the investigated temperature range. A very good agreement is observed between the performed measurements and the model simulations. The characterization process and the subsequent equivalent-circuit parameters extraction at different temperature values are described and discussed.
在这项工作中，对一个声表面波谐振器在0°C至100°C的温度范围内进行导纳（-）参数表征，目的是突出其物理特性如何受到温度变化的影响。使用集总元件等效电路模型来表示在所考虑温度条件下的被测器件，并开发了基于洛伦兹拟合的参数提取过程，用于确定所研究温度范围内的等效电路元件。在进行的测量和模型模拟之间观察到非常好的一致性。描述并讨论了在不同温度值下的表征过程以及随后的等效电路参数提取。
