Abstract :
Radio communications and telecommunications systems designers require currently a higher power level at the filters input in order to increase the receiver sensitivity. In this paper, we present new developments of piezoelectric filters designed with special cut angle quartz crystals and other materials such as Lithium Tantalate and Langasite, allowing to compare the power holding qualities of different cut and different piezoelectric materials.
