SAW Filters

The B39202B9808P810S5 filter is a type of SAW filter. It is designed to reject interference signals, allowing only desired signals to pass through. The filter does this by looking for certain frequencies and amplitudes of the signals that pass through it. In order to do this, the SAW filter utilizes a combination of technological advances developed in surface acoustic wave (SAW) technology. Its main components are a series of electromechanical transducer and integrated circuit (IC) components, which are combined to create an effective filter.

Application Field

The B39202B9808P810S5 filter is typically used in a wide range of applications, including radio frequency communication, instrumentation, medical, consumer, industrial, and military applications. It can also be used for high data rate applications, such as Wi-Fi, WiMAX, ZigBee, and 3G cell phone networks.

Working Principle

SAW filters operate on the principle of surface wave propagation. That is, they use a thin layer of piezoelectric material to create ultrasonic waves that are propagated along the surface of the filter. These waves interact with the electrodes placed on the perimeter of the filter, creating an electrical signal that is either allowed to pass through the filter or is blocked. As different frequencies of signals pass through the filter, their amplitude and phase response are altered, allowing the desired signals to pass through while rejecting interference signals.

The B39202B9808P810S5 filter utilizes a number of advanced features to ensure that the desired signal is separated from the interference signal. This includes placing two series of metal bands around the perimeter of the filter, which act as an absorber, and allowing the interference signal to be absorbed away from the desired signal path. Additionally, it uses an inverse square law filter pattern, which helps to reject interference signals that are at different frequencies than the desired signal.

The B39202B9808P810S5 filter is a great choice for a number of applications. It is highly effective at rejecting interference signals, while allowing desired signals to pass through with ease. Additionally, its size and weight means that it can easily be integrated into most systems and applications. As such, it is an excellent choice for situations where the size and weight of a filter is a major factor.
