SAW Filters - AFS374E Application Field and Working Principle

Surface Acoustic Wave (SAW) filters are a type of band-pass filters that separate the signals of a wide variety of frequencies. They are based on the transmission of acoustic waves across the surface of a piezoelectric material. SAW filters can be used to process different signal types, such as radio frequency, audio, and digital signals. The AFS374E is an example of a SAW filter.

Application Field

The AFS374E is used for wireless communication systems. It is a single pole, low-IF band-pass SAW filter, and has two bands for the 777 MHz and 787 MHz frequencies. The AFS374E is primarily designed for mobile and base station applications using CDMA, GSM, WCDMA, and LTE technologies. It has a passband of 13.6 MHz in the 777 MHz range, and 21.3 MHz in the 787 MHz range.

The AFS374E has an insertion loss of 4.0 dB in passband, and a rejection of 40 dB at the center frequency. It also has a group delay variation of ±10 nanoseconds (ns). The insertion loss, rejection, and group delay variation are key parameters that make the AFS374E an ideal filter for wireless communication systems. Since it has a low insertion loss and good group delay uniformity, it reduces distortions of signals and improves the overall signal quality.

Working Principle

The AFS374E filter is based on the principle of surface acoustic wave (SAW) technology. A signal is mechanical created upon the surface of a piezoelectric material, which results in the generation of an acoustic wave. As the wave propagates across the material it experiences a gradual distortion that is determined by the shape and dimensions of the filter layers. The result is a passband of frequencies, where other signals are reflected, and the desired signal is allowed to pass through.

SAW filters are usually composed of two layers of piezoelectric material, and inter-digital transducers (IDTs). The IDTs create the acoustic wave that travels across the material. The piezoelectric material creates an electrical signal from the acoustic wave generated by the IDTs, and this signal is then amplified and filtered. The result is a signal of the frequencies determined by the filter\'s design.

Conclusion

The AFS374E is a surface acoustic wave (SAW) filter designed for wireless communication systems. It is used to separate the signals of different frequencies and can be used for different signal types. The AFS374E has a low insertion loss, good group delay uniformity, and is based on the principle of SAW technology.
