    SAW Filter Characteristics
    • ■ I / L : Insertion Loss (Lower value is better)
    • ■ Ripple : Peak to Peak value within B/W (Lower value is better)
    • ■ Attenuation : the Gap between I/L Vs Loss(Unwanted Band rejected against passband)

    How Do SAW Filters Work?
  • Highly polished piezoelectric crystal wafer cuts for SAW fi lters are non-dispersive in frequency, i.e. independent of the frequency of the Surface Acoustic Wave, its velocity is almost constant. The piezoelectric eff ect allows for the design of transducers that convert electromagnetic energy from an electronic circuit to acoustic energy (and vice-versa) in the form of a traveling wave on the surface of the crystal. The frequency response of a SAW fi lter is determined by its properties both transduction and refl ection and the interaction of the transducers.
