Additional Details

SAW filters like the B39431-R970-H110 operate by converting an electrical signal into a mechanical wave on a piezoelectric substrate. This wave propagates along the surface and is then converted back into an electrical signal. The filter's frequency response is determined by the design of the interdigital transducers (IDTs) on the substrate. The B39431-R970-H110 is designed to meet the specific performance requirements of the intended application. Its compact size and stable performance make it a suitable choice for a wide range of wireless communication systems.
