Abstract :
A nonlinear behavioral circuit model which reproduces both the amplitude-frequency effect and the frequency characteristic of the second harmonic of the output power is developed. This kind of model is presented for the first time in literature, the simulation results being in good agreement with the measurements performed on a pass-band filter built with three AlN bulk acoustic wave (BAW) resonators.
