چکیده

In this study about the relationships between structural and microwave electrical properties of KTa(1-x)NbxO3 (KTN) ferroelectric materials, a KTN thin film was deposited on different substrates to investigate how KTN growth affects the microwave behavior. Interdigital capacitors and stubs were made on these films through a simple engraving process. Microwave measurements under a static electric field showed the importance of the substrate on the circuit behavior and, notably, on the tuning factor.

Thin Film Ferroelectric Tunable Devices for Reconfigurable Radios

In this paper, a summary of our work in the area of tunable microwave circuits based on thin film ferroelectrics is presented. First, a technique is introduced to improve the linearity of thin film ferroelectric tunable capacitors. Measurements show an improvement in the 3rd order intermodulation point at the input (IIP3) of 16 dB. Next, the design and fabrication of an impedance tuner employin...

Nondestructive microwave permittivity characterization of ferroelectric thin film using microstrip dual resonator

This article presents the use of a microstrip dual resonator for nondestructive permittivity characterization of a ferroelectric thin film at microwave frequencies. The dual-resonator measurement fixture consists mainly of two capacitively coupled microstrip resonators, with the ferroelectric thin film covering the gap between the two resonators. The dielectric constant and loss tangent of the ...

Switchable and tunable bulk acoustic wave resonators based on BaxSr1−xTiO3 thin films

The main focus of this thesis is the study of a novel microwave component, the tunable thin film bulk acoustic wave resonator (TFBAR), based on ferroelectric BaxSr1−xTiO3 thin films. Conventional fixed frequency TFBARs, widely used for filtering applications in wireless communication systems, are based on ordinary piezoelectrics. The tunable TFBAR on the other hand utilizes the dc field induced...
