1. Tunable FBARs: Intrinsic vs. extrinsic tunability.

Author

Gevorgian, S. and Vorobiev, A.

Abstract

The methods used to make the Film Bulk Acoustic Resonators (FBAR) tunable is reviewed. Intrinsically tunable FBARs make use ferroelectrics in ferroelectric and paraelectric (non-polar) phases have tunabilities up to 5% and more. Extrinsically tunable resonators are based on traditional piezoelectric FBARs and make use of external varactors and inductors. The low tunability (<2%) and low Q-factor (Q<100 due to tuning components) limits applications of these resonators. [ABSTRACT FROM PUBLISHER]
