416F27012AAT Application Field and Working Principle

Crystals are substances with a highly ordered atomic or molecular structure due to the precise spacing of their components. As such, crystals possess unique and precise optical and physical properties that make them ideal for a wide range of applications.

The 416F27012AAT is a crystal unit designed for surface acoustic wave (SAW) applications. It consists of a monolithic piezoelectric substrate, a precise pattern of electrodes, and a protective enclosure. The 416F27012AAT is primarily used for telecommunication applications such as cellular phone base stations, wireless local area networks, and satellite communication.

Working Principle

The 416F27012AAT works on the principle of surface acoustic wave (SAW) technology. In this technology, high frequency signals are applied to the parallel electrodes or interdigital transducers (IDT) in the crystal unit. These signals cause surface acoustic waves to propagate along the surface of the piezoelectric substrate. The surface acoustic waves interact with the IDTs creating an oscillating electric field that can be detected and processed.

The frequency of the surface acoustic waves (SAWs) is determined by the spacing of the electrodes. Thus, the 416F27012AAT can be precisely tuned to a specific frequency. This makes it ideal for use in telecommunication applications as it can be used to generate kHz frequencies to hundreds of GHz frequency.
