Bragg reflector acoustic impedance RLC model
Main Article Content
Abstract
The simplified RLC model of Bragg reflector impedance was developed and presented in this work. The model allows the straightforward integration of the reflector’s electrical behavior into the most of modern CAD systems as a part of complex devices and enables the precise evaluation of the output characteristics in a relatively wide nearresonant
frequency range. This is especially important in the modelling of RF systems composed of thin film bulk acoustic resonators. The model verification was given including the analysis of the total impedance frequency dependence in wide and narrow frequency ranges, the model agreement examination for different number of layers and using various materials. The evaluation of agreement error for different frequency bands presented which allowed one to determine the limits of applicability of RLC model. An important advantage of proposed solution is the decreasing of calculation time and improving of optimization efficiency of complex RF circuits with a large number of resonators.
