Additional Details

SAW filters utilize the piezoelectric effect to convert electrical signals into mechanical waves on the surface of a piezoelectric substrate. These waves propagate along the surface of the substrate and are then converted back into electrical signals at the output. The filter's characteristics are determined by the design of the interdigital transducers (IDTs) on the surface of the substrate.

The SFR836BY002 is designed to meet the stringent requirements of modern wireless communication systems. Its robust design and excellent performance make it a reliable choice for a wide range of RF applications. It is typically used in the front-end of receivers to filter out unwanted signals and improve the overall performance of the system. The specific insertion loss, attenuation, and bandwidth characteristics can be found in the official EPCOS (TDK) datasheet for this part.
