Temperature stable SAW RF filters are needed in modern mobile communication applications. This paper shows the constructive and technological possibilities of SAW filters to improve the temperature stability. Now two strategies are extensively developed to improve the temperature stability, first one is based on deposition of SiO2 layer and second is use of the wafer bonding. This paper reviews resent progress of SAW temperature stable RF filters techniques and their implementation into real devices were discussed.
