Abstract:

This paper presents novel multilayer tuneable high Q-filters based on hairpin resonators including ferroelectric materials. This configuration allows the miniaturization of these filters to a size that makes it suitable for chip & package integration and narrow band applications. The multilayer structure allows for high Q by supporting a dielectric mode instead of a conductor transmission line mode. Different configurations of band reject filters are presented to illustrate the benefits of the present design.
