SAW filters are a type of filter used to separate or reduce some frequency range of signals. One example of such a filter is the B39941B4380P810 SAW filter. The application fields of this filter and its working principle will be discussed here.

Application Fields of B39941B4380P810 SAW Filters

The B39941B4380P810 SAW filter is designed for use in television applications where low stopband attenuation and steep skirt slopes are desired. Common applications for this filter can be found in television receivers, cable modems, tuners, decoders, data processors, and other similar systems. This type of filter enhances signal quality throughout the equipment and eliminates unnecessary noise signals.

This filter has been designed to meet the stringent electrical specifications set out by the International Radio Consultative Committee (CCIR). The filter has a passband edge of 72 MHz and a stopband edge of 65 MHz when operated at a center frequency of 71 MHz, giving it a wide operational range. It also features a frequency response of 0.135 dB, making it ideal for use in television applications.

Working Principle of B39941B4380P810 SAW Filters

B39941B4380P810 SAW filters utilize surface acoustic wave (SAW) technology. This type of filter makes use of a piezoelectric substrate containing several layers of conductive material on one side. Electrical signals are applied to the filter through these layers, creating a surface acoustic wave (SAW) that propagates through the substrate. The wave is then reduced in amplitude as it passes through the filter, allowing the desired frequencies to pass while eliminating the undesired frequencies.

SAW filters can be manufactured with different characteristics, such as bandpass, notch, or low-pass filters. The B39941B4380P810 SAW filter is designed as a bandpass filter, with a specified passband edge of 72 MHz and a stopband edge of 65 MHz when operated at a center frequency of 71 MHz. The filter also features a frequency response of 0.135 dB.

Conclusion

In conclusion, the B39941B4380P810 SAW filter is a filter used primarily in television applications. Its passband edge is 72 MHz and its stopband edge is 65 MHz when operated at a center frequency of 71 MHz. This filter also features a frequency response of 0.135 dB. This filter utilizes surface acoustic wave (SAW) technology, which allows it to reduce unwanted frequencies while allowing the desired frequencies to pass through. This makes it ideal for use in television applications, and it has a wide operational range to meet the stringent electrical specifications set by the International Radio Consultative Committee (CCIR).
