SAW Filters – B39391B3649U310A11 Application Field and Working Principle
What is a SAW Filter?SAW filters are also known as surface acoustic wave filters. They are used in electronic communication systems that involve radio frequencies. SAW filters are actually resonators that are specially designed to generate specific frequencies in their output signal.What Does a SAW Filter Do?
The primary purpose of a SAW filter is to provide bands with selectivity so that a user can filter out unwanted frequencies while still allowing the wanted frequencies to pass unhindered. In short, SAW filters allow unwanted frequency components to be isolated from the desired signal while still allowing the desired signals to pass through without delay or distortion.Application of the B39391B3649U310A11 SAW Filter
The B39391B3649U310A11 SAW filter is specifically used in a wide range of pressure and temperature monitoring applications. These applications include aircrafts, industrial data centers, automotive displays, elevators, and environmental monitoring systems as well. Working Principle of the B39391B3649U310A11 SAW Filter
The B39391B3649U310A11 SAW filter works on the principle of ‘transduction’. In this process, the input signal is converted into a mechanical waveform. The mechanical waveform thus created is then used to create a surface acoustic wave. The filter then uses this wave in order to provide resonance at specific frequencries. The output of the surface acoustic wave is then converted back into an electrical signal at the required frequency. The generated electrical signal is then used to generate a proportional output signal which is then used to monitor and control the pressure and temperature levels.Advantages of Using the B39391B3649U310A11 SAW Filter
