SAW filters

SAW filters abbreviation of SAW Surface Acoustic Wave Filters, a small size, light weight, reliable performance, no complex adjustment features. Is the use of piezoelectric ceramic piezoelectric effect piezoelectric crystal oscillator material, the physical properties of acoustic wave propagation is made of a transducer passive bandpass filter. As IF SAW filters, RF input circuit selected frequency components, often used in video recorders and televisions, instead of frequency, the RF amplifier input snubber circuit and multi-level tuning circuit. SAW filters are made of quartz, lithium niobate, barium titanate crystals, a material made of piezoelectric effect. When the crystal is subjected to mechanical action, resulting in the phenomenon of the electric field proportional to the pressure. Crystals have piezoelectric effect when subjected to an electric signal effect, will produce elastic deformation issued mechanical waves (sound waves), you can put sound into electrical signals. Since this is only the crystal surface acoustic wave propagation, so called SAW.
