Abstract: The present invention provides a dielectric ceramic composition comprising a base material represented by the general formula: (x) Al2O3+(y) TiO2, where x and y are percentages of the total weight of the base material, with x being in the range of about 60 to about 96 and y being in the range of about 4 to about 40. Also provided is a first additive material comprising Nb2O5 and a second additive material comprising BaZrO3. In another embodiment the present invention provides a sintered dielectric ceramic composition comprising a base material represented by the general formula: (x) Al2O3+(y) TiO2, where x and y are percentages of the total weight of the base material, with x being in the range of about 60 to about 96 and y being in the range of about 4 to about 40. Also provided is a first additive material comprising Nb2O5 and a second additive material comprising BaZrO3.

Abstract: The present invention provides at least two input driving sections for a piezoelectric transformer. The two input driving sections are configured in a stacked configuration, with either one section on top of the other or the sections interlaced. Each input driving section includes a pair of electrodes. All of the electrodes preferably have a distinct electrode shape. The two input driving sections provide for the application of phase-modulated input signals to control the gain or amplitude of the transformer output.

Abstract: The present invention provides a method of mounting a piezoelectric device having a plurality of mounting pads directly to a printed circuit board comprising the steps of providing a piezoelectric device, miniature conductive springs and a printed circuit board, attaching the springs to mounting pads of the piezoelectric transformer, and attaching the springs to the printed circuit board. Also disclosed is an apparatus made according to the method.
