SAW Filters

B39321B3783Z810 application field and working principle

Surface Acoustic Wave (SAW) filters are used for filtering in many different application fields. They are widely used in broadcasting, telecommunications, navigation systems and spectroscopy, being one of the most popular forms of active RF filter. The B39321B3783Z810 is also a SAW filter that can be used for various applications.

The B39321B3783Z810 is designed to contain a passband over the range of 698 MHz to 2.7 GHz with high attenuation in the stopband outside this range. Its wide bandwidth makes it suitable for applications ranging from wireless radio frequency communications systems to satellite communications. It is characterized by having both good electric and acoustic properties, making it ideal for use in low-power systems.

B39321B3783Z810 Operation Principle

The B39321B3783Z810 is based on the principles of SAW filters. This type of filter utilizes acoustic shear waves to filter signals. When a signal is fed through this type of filter, it causes the acoustic shear waves to move in an up-and-down motion along the surface of the filter. This creates areas within the filter where the signal is blocked (the stopband) and areas where the signal is passed through (the passband).

The B39321B3783Z810 is designed to control the size of the passband and stopband by controlling the frequency response of the filter. This is done by using an acoustically designed substrate, upon which acoustic waves can travel, to control the speed of the acoustic shear wave. To further control the frequency response of the filter, the filter is designed with metal electrodes. These electrodes vary in their length and thickness, depending on the application for which they are used.

By manipulating the parameters of the electric and acoustic properties of the filter, the B39321B3783Z810 can be designed with a specific passband and stopband frequency. Therefore, it is suitable for various applications ranging from broadcast to satellite communications.

Conclusion

The B39321B3783Z810 is a SAW filter designed to filter signals over the range of 698 MHz to 2.7 GHz. To achieve this, it incorporates both electric and acoustic properties which it uses to control the size of the passband and stopband. This makes it suitable for a wide range of applications, from wireless communication to satellite communication.
