Surface Acoustic Wave (SAW) filters are electronic devices based on acoustic principles and used as band-pass, band-stop, and notch filters. These devices are commonly used for communications, instrumentation, and audio applications. B39202B3515H910 is an example of a SAW filter used for high frequency selection. This article explores the application field and working principle of B39202B3515H910.

Application field of B39202B3515H910

B39202B3515H910 is a SAW filter designed to operate at high frequency. It has a center frequency at 2500MHz and a bandwidth of 500MHz. The filter is exceptionally wide and can enable a system to perform frequency selection for wide frequency range applications. This means it can control the frequency range by allowing frequencies within the range to pass, while blocking out any frequencies that are not in the specified range. It can also be used to enhance signal quality and reduce energy interference.

B39202B3515H910 is most commonly used in wireless communication systems such as Local Area Networks (LANs). It can be used in the access point of the LANs to select and rectify signals within specific frequencies. Other applications of B39202B3515H910 can be found in automotive, aerial, medical, and satellite communications. These devices can improve data transmission rate and enhance the overall quality of signals.

Working Principle of B39202B3515H910

The B3920B3515H910 SAW filter works on the same principles as other SAW filters. It utilizes a piezoelectric crystal substrate as its main component, which produces a surface acoustic wave when energized. The crystal is generally Quartz, which is a crystalline material that has been selected due to its crystalline microstructure and its ability to generate wanted frequencies when energized. There are four electrodes located on the B39202B3515H910 SAW filter, two of which provide the RF input, while the other two serve to receive the output waveform. When an RF signal is input, the excited crystal will send an acoustic wave on its surface. This wave propagates from one end to the other, while its amplitude is affected by the electrodes situated along its path. This phenomenon then modifies the signal width by setting a frequency boundary, thus allowing some frequencies to pass through, while others are eliminated.

The B39202B3515H910 is a high Q device, meaning that it provides a higher selectivity when compared to other SAW filters. This is due to its wide bandwith of 500 MHz. Consequently, this filter can successfully identify and process RF signals within an exceptionally broad frequency range, allowing only the desired signals to pass, while removing any harmful signals. As a result, the B39202B3515H910 SAW filter can be used to significantly enhance signal fidelity.

Conclusion

The B3920B3515H910 SAW filter is a high-performance device designed for use in high-frequency systems. It is primarily used for wireless communication applications such as LANs, medical systems, and satellite communications. The working principle of this filter relies on a Quartz crystal as its base component, which enables the filter to effectively filter out signals outside of the pre-defined bandwidth. As a result, the B39202B3515H910 filter increases data transmission rate and enhances the overall signal quality.
