B39440-X6855-N350 SAW Filters: Application Field and Working Principle

SAW (Surface Acoustic Wave) filters are part of a wide range of frequency control components that employ surface acoustic wave technology. The approximate size of a SAW filter is from 3.3mm x 3.3mm x 1mm up to 22mm x 22mm x 4.5mm. They have a wide range of applications, such as radio- wave interference suppression, A/V equipment, multi-media, wireless communication, and signal acquisition and analysis. B39440-X6855-N350 SAW filters are part of this range of frequency control components and they fulfill the various needs of the applications mentioned above.In this article, the application field and working principle of the B39440-X6855-N350 SAW filter will be discussed in greater detail.

One of the major application fields for B39440-X6855-N350 SAW filters is cellular phones. In cellular phones, these SAW filters provide the very stringent rejection and selectivity requirements. Additionally, these SAW filters help in providing high frequency stability, minimal drift and high linearity by using the IC technology.B39440-X6855-N350 SAW filters can also be used in a wide variety of wireless communication networks, such as the GSM/3G, CDMA and WCDMA standards. The SAW filters are used to selectively pass the wanted signals and reject unwanted signals, while bypassing spurious signals. These filters also help in suppressing interference caused by the other radio wave transmission systems as well.Additionally, B39440-X6855-N350 SAW filters have other applications, such as in automotive systems, GPS systems, measurement instrumentation and satellite receivers. These filters are designed for both low to medium and high frequency bands and can be custom-made to suit specific requirements.

Working Principle of B39440-X6855-N350 SAW Filters

The basic working principle of SAW filters is based on the acoustic wave propagation in a piezoelectric substrate material. A SAW filter consists of a piezoelectric substrate, such as quartz or lithium tantalite, and is covered with a metallic coating, such as gold or chrome. When a signal is applied to the SAW filter, the electrical field causes stress to the piezoelectric material which then generates mechanical vibrations in the material. Due to the property of acoustic-wave propagation in the piezoelectric material, these vibrations travel along the surface of the material as sound waves. The frequency-dependent acoustic signal propagation acts as a band-pass filter, allowing the transmission of only the frequencies at its pass-band, and rejecting other frequencies.

Conclusion

B39440-X6855-N350 SAW filters are frequency control components that can be used for different types of applications. Some of the major applications of these filters are cellular phones, radio-wave interference suppression, GPS systems and automotive systems. The basic working principle of these SAW filters is based on the acoustic wave propagation in the piezoelectric material. In conclusion, the B39440-X6855-N350 SAW filters can be used to satisfy the stringent requirements of different applications, thanks to their high frequency stability, low drift and high linearity.
