KTN ferroelectric thin-films: Application to the realization of tunable microwave devices

Abstract

Interdigital capacitors were fabricated on KTa0.5Nb0.5O3/Sapphire substrate. Since their measurements demonstrated the high tuning factor of KTNs, we designed and fabricated three distributed phase shifters. To our knowledge, they are the first phase-shifters realized on KTN thin films at microwave frequencies. These circuits present interesting phase-shifts, but their Figures of Merit are weakened by high KTN dielectric losses mainly responsible for the observed insertion losses; thus, in a near future our investigations will mainly focused on this issue.
