Abstract :
This paper analyzes design routines for their suitability in the design of tunable capacitances (varactors) based on the Barium-Strontium-Titanate (BST) thick-film technology, concerning their static and dynamic description of the component´s properties. After a short introduction of the thickfilm process the design rules for planar varactors are discussed in detail. Especially, a guideline for maximizing the tunability of the component is discussed by choosing the right geometry parameters.
