According to recent research published in the journal IEEE Transactions on Ultrasonics Ferroelectrics and Frequency Control, "Using the stacked crystal filter (SCF) concept, a coupled resonator filter (CRF) call be interpreted as a device in which 2 piezoresonators are stacked oil top of each other in such a way that a certain degree of acoustic interaction Occurs. The work presented in this paper reports a novel all-electrical model for the CRF."
"The model associates acoustical coupling with all equivalent electrical coupling between resonators. The resulting equivalent circuit makes it possible to apply classical filter synthesis techniques directly based oil ...
