“…A decrease of the series resonance frequency as the excitation amplitude increases has been observed in the case of an AlN stack crystal filter (Ketcham et al, 1988). The intermodulation effect consists, for example, in measuring some harmonic components of the response to a sinusoidal excitation (Nosek, 1999;Aigner et al, 2005;Ketcham et al, 1988). The shift of the series resonance frequency as a function of bias voltage is the bias-frequency effect (Aigner et al, 2005).…”

“…20). A high power fed into the BAW resonator produces three nonlinear effects, namely: the amplitude-frequency effect, the intermodulation effect, and the bias-frequency effect (Nosek, 1999;Aigner et al, 2005). The amplitude-frequency effect is illustrated by the series resonance frequency increase as excitation amplitude increases for a quartz resonator (Fig.…”

“…Currently the piezoelectric effect is not strong enough to change the center frequency significantly. For instance for BAW filters typically the frequency change is less than 20 ppm/V [33] which means 0.2% variation at the resonance frequency even if we apply a DC voltage of 100V. There is an active research community proposing new materials and implementation techniques, however widely tunable acoustic wave filters are not yet available [34].…”

“…The bias dependence has been investigated before [42,43]; however, an explanation for the observed effect was not given. Others discussed the strain dependence of the parameters extensively [44,45], however, they did not discuss the effect on the impedance curves.…”
