COTX SAW Band Pass Filter

Surface acoustic wave (SAW) band pass filters employs the piezoelectric effect to convert an electromagnetic signal into an acoustic signal and vice versa. A SAW bandpass filter provides sharp cut-off, very linear phase characteristics, high stability, and is highly reliable. Electrical signals are converted to a mechanical wave in a piezoelectric crystal or ceramic device. The wave is delayed as it propagates across the device before being converted back to an electrical signal. The delayed outputs are recombined to produce a direct analog implementation of a finite impulse-response filter.
