SAW filters, Surface Acoustic Wave Filters
- summary or tutorial about the basics of the surface acoustic wave filter
or SAW filter used in radio receivers and radio communications applications.
Surface Acoustic Wave (SAW) technology is used in many areas
of electronics to provide resonators for oscillators, filters and transformers.
One of the major uses of these devices is as SAW filters which find widespread
use in radio applications. These SAW filters provide good performance filtering
solutions while offering a cost effective solution.
SAW filters are widely used in cell phone applications for
filtering. Here they provide considerable advantages in terms of cost and size,
in an environment where these two aspects are of considerable importance.
Additionally their importance in the cellular industry has meant that
considerable amounts of research and development have been undertaken on SAW
filter s in the last 20 years, and their performance has improved considerably
in this period.
