Surface Acoustic Waves (SAWs), also known as longitudinal acoustic phonons (LAPs), are acoustic waves that travel on the surface of solids. They are created when an electrical signal is passed through a thin-film piezoelectric transducer on the surface of a material, which creates a mechanical wave. These mechanical waves can then be used to generate an electrical signal in another thin-film piezoelectric transducer.

SAW filters are used to filter out unwanted signals in radiofrequency (RF) applications. The AFS14A35-1591.50-T2 is one of many different types of SAW filters. It is used in RF applications such as cellular phones and radio communications. This filter can be used to reduce the interference of an unwanted signal in the desired frequency range.

The working principle of the AFS14A35-1591.50-T2 SAW filter is based on the propagation of surface acoustic waves along a piezoelectric substrate. The filter is composed of a piezoelectric substrate, an interdigital transducer (IDT) and an acoustic reflector. The IDT has an array of metal electrodes on the substrate and acts as an antenna, converting the RF signal into surface acoustic waves. The acoustic reflector is placed at the end of the substrate and reflects the surface acoustic waves back towards the IDT.

When the acoustic waves reach the IDT, the IDT converts the signal back to an electrical signal. The signal is then filtered by the SAW filter. The frequency response characteristics of the filter depend on the geometry of the IDT. The SAW filter is designed to reject frequencies that are outside the desired frequency range. This means that the filter can reduce unwanted signals in the desired frequency range, allowing the desired signal to pass through.

The AFS14A35-1591.50-T2 SAW filter is designed for use in cellular phones and radio communications applications. It is used to reduce the interference of unwanted signals in the desired frequency range, allowing only the desired signal to pass through. This makes it an effective way to improve the signal quality and reduce the amount of interference in the communication system.
