SAW Filters

B39192B5111U410 is a SAW Filter (Surface Acoustic Wave) that plays an important role in the electronics industry today, especially in signal processing applications. This specific filter often works in the range of 27.12MHz to 40.68MHz for WCDMA applications. It also provides both high selectivity and steep skirts for this purpose.

Application Field

This particular type of filter is put to use in a variety of applications that require high selectivity with minimal loss (< 0.5dB) when blocking any signal that lies beyond the passband. As mentioned, this filter is often used for 3G and 4G applications. One example is mobile phones which often integrate this type of filter. It can also be useful for GPS systems, communications systems, FM reception systems, TV broadcast receivers, WIFI receivers, RADAR systems, and satellite systems.

Working principle

Like many other filters, the B39192B5111U410 SAW filter is composed of electronic components such as inductors and capacitors. However, it also requires the use of surface acoustic waves, which are waves produced by vibrating crystals. These waves, propagating away from the crystal, can be used to separate, or filter, audio frequencies.

The crystalline material used to transmit these waves is usually quartz. In the case of the B39192B5111U410, it is packed between two metallic plates, and, when a signal is applied, the resulting vibration on the surface of the quartz allows it to produce the desired filtering effect.

Multiple quartz elements can be used to create more complex filters with more specific parameters. In the case of the B39192B5111U410, there are three parallel quartz elements that work in conjunction to transmit the desired sound frequencies and block out any others.

Conclusion

The B39192B5111U410 filter is an essential electronic component in many signal processing applications. It is an example of a SAW filter, which uses surface acoustic waves to transmit specific frequencies while blocking out any other signals not in the passband. The B39192B5111U410 is particularly useful for 3G and 4G applications in mobile phones, GPS systems, communications systems, FM reception systems, TV broadcast receivers, WIFI receivers, RADAR systems, and satellite systems.
