An ideal filter would, in theory, possess no loss, an instantaneous transition from the pass band to the stop band, infinite stop band attenuation, no signal distortion introduced by the filter, and have very small size and cost. However, the reality is that many tradeoffs must be considered when selecting the best filter for system design applications. SAW filter technology offers advantages of reduced size and weight, which result in lower overall costs. This white paper presents general SAW theory and performance to better understand the technology and use it to its greatest advantage.
