Surface Acoustic Wave (SAW) filters employ the propagation of acoustic waves over the surface of a piezoelectric crystal in order to separate, amplify, or select desired frequencies from an input signal. The AFS315E is a type of SAW filter typically used in communications and radio frequency (RF) applications. It is designed to offer a wide range of performance capabilities while still being affordable.
The AFS315E is an RF filter that operates in the frequency range from 890MHz to 920MHz. It uses two sets of resonators, one to extract the input signal and the other to act as a low-pass filter to reject unwanted frequencies. It has a remarkably wide passband ranging from 890MHz to 920MHz with minimal levels of insertion losses, return losses, and intermodulation distortion. The typical insertion loss is 0.45dB while the return loss is greater than 10dB. The nominal 3dB bandwidth of 4MHz makes the AFS315E well-suited for use in wireless communication systems.
The AFS315E uses a method known as surface acoustic wave (SAW) technology, which involves the propagation of acoustic waves over the surface of a piezoelectric substrate. The substrate is composed of a piezoelectric material, typically quartz, and a metallic conductor. When RF signals are applied to the substrate, it vibrates and generates acoustic waves. These surface acoustic waves propagate along the surface of the substrate, guided by “gratings,” which are metal interdigital transducers (IDTs) printed on the substrate. As the waves propagate past IDTs, their frequencies are selected and amplified. The result is a filtered signal that has low levels of distortion.
The AFS315E is designed for use in the increasingly popular Digital Video Broadcasting (DVB) and cordless handset applications. It is small and compact, offering a very high level of performance for its size. The AFS315E is also suitable for use in repeaters, base stations, and other radio equipment. It is easily integrated into larger systems and offers reliable operation even under harsh environmental conditions. The AFS315E is a valuable asset to any system designed to work in the 890-920 MHz frequency range.
