What are the Filtering Differences Between SAWs and RAWs?

The article focuses on difference between Surface-Acoustic-Wave (SAW) and Bulk-Acoustic-Wave (BAW) in terms of employing acoustic waves and performance levels. Topics include acoustic waves traveled across surface of elastic, piezoelectric material with wave amplitude in SAW component, waves traveled through and stored in piezoelectric material in BAW component, drift in frequency with temperature in SAW filters in comparison to BAW filters, SAW oscillators from Synergy Microwave Corp.
