Additional Details:

SAW filters like the TFS199E operate by converting electrical signals into mechanical (acoustic) waves on a piezoelectric substrate. These waves propagate along the surface of the substrate and are then converted back into electrical signals. The filter's frequency response is determined by the design of the interdigital transducers (IDTs) on the substrate. The TFS199E is typically used in the IF stage of a receiver or transmitter to filter out unwanted signals before further processing. Its specific frequency characteristics (center frequency, bandwidth, insertion loss, and attenuation) are precisely tuned to meet the requirements of the target application.
