Surface acoustic wave (SAW) filters are components that enable electronic systems to transmit or filter out data in specific frequencies or narrow bands of frequencies. They are often used in radios, cellphones, and other wireless applications. The B39791B7942P810SAW filter is a specific type of SAW filter typically used in mobile communication systems. It has a variety of uses, a specific working principle, and is a reliable component for radio systems.

Application Field

The B39791B7942P810 SAW filter is specifically designed for use in mobile communication systems, such as cellphones and radios. It is a two-pole filter, meaning that it can filter out two frequencies at once. It can be used to filter out frequencies in radios, cellular base stations, and other wireless systems. It can also be used to filter out interference in digital audio systems.

The B39791B7942P810 SAW filter has a wide range of applications in the telecommunications industry. It can be used in cellphone networks to filter out unwanted frequencies, or in radio systems to ensure that only specific frequencies are transmitted. It can also be used in digital audio systems to enhance sound quality and reduce distortion. The filter has a low insertion loss, meaning that it introduces minimal interference into the signals it is filtering.

Working Principle

The B39791B7942P810 SAW filter works by using surface acoustic waves to filter out unwanted frequencies. It consists of a piezoelectric substrate layer, a metallic reflector layer, and an electrode layer. A high-frequency electrical signal is applied to the electrode layer, which generates an acoustic wave in the piezoelectric layer. This wave then reflects off of the metal reflector, creating interference patterns.

The interference patterns within the B39791B7942P810 SAW filter are determined by its design. The filter can be designed to allow or filter out certain frequencies, depending on the application. The device can filter out frequencies as low as 8 kHz and as high as 20 MHz.

Conclusion

The B39791B7942P810 SAW filter is a reliable and efficient device that can be used in a variety of applications and systems for filtering out specific frequencies. It can be used in mobile communication systems, digital audio systems, and radio systems to ensure that unwanted frequencies and interference are filtered out. The filter’s working principle is based on surface acoustic waves, and its design determines which frequencies will be blocked out. It is a reliable component for many different types of electronic systems.
