Radio Frequency (RF) Filter Tuning Element

This proposed effort will focus on the design, development and analysis of a high voltage BST based varactor for tunable filter applications. The high voltage BST varactor will enable wide tuning range filters with high quality factor and increased power handling and linearity. Advanced filter design techniques will also be leveraged to increase the effective quality factor of the filter resonator for both tunable notch and tunable bandpass filters. Furthermore, filter specifications and interface definitions will be developed to enable transition into a wideband reconfigurable RF system in the anticipated Phase II effort.The performance of the high voltage BST varactor will be verified in Phase I via bench-top measurements of fabricated example devices.
