Additional Details

SAW filters like the B39162-B9100-L410-S09 utilize piezoelectric materials to convert electrical signals into mechanical surface acoustic waves. These waves propagate along the surface of the material and are then converted back into electrical signals. The design of the interdigital transducers (IDTs) on the surface determines the filter's frequency response. Proper impedance matching and PCB layout are crucial for achieving optimal performance. Typically designed to operate with a 50-ohm impedance, careful attention should be paid to the surrounding circuitry to minimize signal reflections and losses.
