SAW filters are sophisticated electronic components used in a variety of applications, ranging from telecommunications to automotive radar systems to consumer electronics. The B39871B3749H110 filter is a SAW filter that can be applied in high frequencies and is used for communication systems. This article will discuss the application field of the B39871B3749H110 filter and its working principle.

The Application Field of the B39871B3749H110 Filter

The B39871B3749H110 filter is used in communication systems, particularly in mobile phones, television, and radio broadcasting, for filtering out unwanted high frequency signals. The filter is also used to improve the signal-to-noise ratio (SNR) of a signal. In addition, the filter can be used for suppressing interference from other signals that have a higher frequency than the signal of interest. The B39871B3749H110 filter is also used in car audio systems, home theater systems, satellite systems, and consumer electronics.

The Working Principle of the B39871B3749H110 Filter

The B39871B3749H110 filter is a SAW filter, which stands for Surface Acoustic Wave Filter. This type of filter works by using the phenomenon of surface acoustic wave propagation. In this mechanism, an acoustic wave is generated on the surface of a piezoelectric material, and this wave is converted into an electrical signal. The surface acoustic wave filter works by allowing a signal of a certain frequency to pass through, while simultaneously blocking out other signals with higher or lower frequencies.

The B39871B3749H110 filter is composed of a substrate, which is a non-piezoelectric or semiconductive material, and a piezo-electric material, such as quartz. A pair of electrodes, referred to as an IDT (interdigital transducer), are placed on the substrate. A specific electric signal is then applied to the IDT, which produces an acoustic wave in the piezo-electric material. The electric signal is then converted back to an electrical signal by the IDT, which is then filtered and passed through to the output terminals.

In conclusion, the B39871B3749H110 filter is a SAW filter that is used in a variety of applications, ranging from telecommunications to automotive radar systems. The filter works by using the phenomenon of surface acoustic wave propagation, which uses an electric signal to generate an acoustic wave in a piezo-electric material. This signal is then converted back to an electrical signal by an IDT, which is then filtered and passed through to the output terminals.
