摘要

本文介绍了用于调谐的铁电变阻器的最新进展。虽然基于钛酸钡锶(BST)的厚膜组件以前是在平面数字间(IDC)拓扑中实现的，但低烧结BST复合材料提供了金属-绝缘体-金属(MIM)结构的可能性。讨论了该技术在大功率应用中的可能性和局限性，特别是考虑了功率处理能力和线性度。具有1kW非常高额定功率的厚膜元件显示声学效果，在设计时必须仔细考虑。

Ferroelectrics for Tunable High-Power Applications

This paper presents recent development of ferroelectric varactors for tuning applications. While Barium-StrontiumTitanate (BST) based thick-film components have formerly been realized in planar interdigital (IDC) topology, low-sintering BST composites offer the possibility of metal-insulator-metal (MIM) structures. The possibilities and limits of this technology are discussed in respect to high-power applications, especially the power handling capability and linearity are considered. Thickfilm components with very high power rating of 1kW show acoustic effects, which have to be carefully considered in the design.
