← ScienceWhich outcome occurs when a SAW filter reaches saturation?
A)Signal distortion and added harmonics✓
B)Reduced insertion loss at passband
C)Enhanced stopband attenuation occurs
D)Phase linearity and reduced group delay
💡 Explanation
Signal distortion occurs because the piezoelectric crystal's **nonlinear electromechanical coupling** generates harmonics. Therefore, signal integrity diminishes as the crystal's linear capacity is exceeded, rather than maintaining filter characteristics at higher signal amplitudes.
