Abstract:
Because of its excellent Q and electromechanical coupling, Lithium Tantalate LiTaO3 is an attractive material for new piezoelectric resonators which can not be realized by Quartz or Ceramics. Lithium Niobate LiNbO3, which is one of the family of LiTaO3, has not as good frequency temperature characteristics as LiTaO3 resonators. The area of industrial application for LiTaO3 is expanding rapidly. Examples of this are voltage controlled oscillators VCXO with a broad range of pullability, wide passband filters and SAW filters. Especially, SAW devices for IF filter of the TV set are industrialized widely. Besides the basic research for the study of LiTaO3 resonators were reported. Also, practical application of LiTaO3 for monolithic filter was reported. This paper reports the development of a miniature LiTaO3 X-Cut strip resonator enclosed in cylindrical can, which is presently used for wrist watch crystals.
