SAW filters
DESCRIPTION
Filters on surface acoustic waves (SAW filters) are widely used today in the communication systems, due to the combination of enhanced electric characteristics (in particular, small insertion loss, high selectivity and small squareness ratio) with small dimensions. Moreover, SAW filters are more stable under external impacts, as compared to their analogs based on LC-elements and piezoceramics.The main advantages of SAW filters are resulting from their structure: Small dimensions;independence of the phase response from the amplitude-frequency response (AFR);AFR small squareness ratio;Excellent off-band rejection;temperature stability.
