Additional Details

The B39192-B5180-U410 SAW filter operates based on the principle of converting electrical signals into mechanical waves on a piezoelectric substrate. These mechanical waves propagate along the surface of the substrate and are then converted back into electrical signals. The filter's characteristics are determined by the design of the interdigital transducers (IDTs) on the substrate. The exact specifications of this filter, such as center frequency, bandwidth, insertion loss, ripple, and temperature stability, are critical for its proper implementation and can be found in the product datasheet. It is designed to operate within specific frequency bands used in various wireless communication standards. It is typically available in a surface-mount package, simplifying its integration into PCB layouts. Proper impedance matching and circuit design are important to achieve optimal performance from this SAW filter. Always consult the datasheet to adhere to the recommended operating conditions and ensure the desired performance characteristics are achieved.
