Surface Acoustic Wave (SAW) filters are among the most popular RF building blocks in modern wireless communication systems. These passive components are used in the design of receivers, transmitters, and transceivers. B39311B3938H110 is one of the most popular SAW filter products on the market. This article will explore the application fields and working principle of the B39311B3938H110 SAW Filter.

Application Fields of B39311B3938H110

Due to its wideband coverage, B39311B3938H110 SAW filter is especially suitable for modern wireless communications systems that require a wide frequency range. This filter offers an excellent level of performance, as well as a low insertion loss even at high frequencies. This makes it an ideal choice for applications such as cellular mobile phones, wireless networks, satellite services, point-to-point radios, and automotive systems.

Working Principle of B39311B3938H110 Filter

The B39311B3938H110 SAW filter is based on a canonical platform that functions by leveraging acoustic waves. As the name suggests, the primary mechanism for this filter involves the use of surface acoustic waves. These waves are produced by interdigitated comb-like transducers which are bonded to piezoelectric substrates.Electrical signals are converted to acoustic energy that is then directed along the surface of that substrate. Along its path, the acoustic wave is reflected, absorbed, and transmitted depending on the characteristics of the substrate material.

The way this filter works is relatively simple. When an electrical signal is input to the filter, acoustic waves are generated and travel across the substrate. The periodic structures on the substrate\'s surface act as filtering elements, which interact with the acoustic waves and modify the signal according to the filtering specifications.The resulting signal is then received and converted back to an electrical signal.

In Conclusion

B39311B3938H110 SAW filter is a versatile, high-performance component suitable for use in various wireless communication systems. Its wideband coverage and low insertion loss enable it to be used in a wide range of applications. The filter works based on the interaction between acoustic waves and the periodic structures on the substrate, which are responsible for the filtering specifications.
