Abstract : Tunable Dual Behavior Resonators were realized on using KTN ferroelectric thin-films. Their measurements demonstrated an agility of more than 21% in the 6.2-7.6 GHz frequency range under an applied field of 80 kV/cm. At the same time, insertion losses at the center frequency decreased from 3.27 to 2.06 dB; reflection losses were better than 11.5 dB at the same frequency. This study evidenced the potential of the DBR structure for tuning applications as well as the high tuning factor of KTN thin-films at microwave frequencies.
