Closed Loop Frequency Control for Tunable High Quality Factor Filters

The proposed project will focus on the development of closed loop frequency control hardware and algorithms for control of high quality factor tunable microwave filters based upon evanescent mode resonators. The developed controller will be modeled in Matlab to predict overall speed and stability. Furthermore, as size is always a concern for current and next generation DoD systems, the proposed effort will also focus on applying SiP concepts to drastically reduce the overall size of the filter feedback and control hardware and preserving the compact form factor provided by substrate integration of the evanescent mode resonators. The modeled controller and developed packaging approach will provide a solid foundation from which a Phase II effort will be based upon.
