Towards the Optimization of Apodized Resonators [PDF]

open access: yesMicromachines
Bulk Acoustic Wave (BAW) resonators are essential components in modern RF communication systems due to their high selectivity and quality factor. However, spurious resonances caused by Lamb wave mode propagation along the in-plane directions degrade the ...

Optimized reflector stacks for solidly mounted bulk acoustic wave resonators [PDF]

open access: yesIEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2010
The quality factor (Q) of a solidly mounted bulk acoustic wave resonator (SMR) is limited by substrate losses, because the acoustic mirror is traditionally optimized to reflect longitudinal waves only.

The High Q Factor Lateral Field–Excited Thickness Shear Mode Film Bulk Acoustic Resonator Working in Liquid [PDF]

open access: yesMicromachines, 2016
A high Q factor film bulk acoustic resonator operating in thickness shear mode excited by a lateral field is described in this paper. The influence of electrode parameters on the resonator performance is studied by the finite element method.

Aluminium Nitride Solidly Mounted BAW Resonators with Iridium Electrodes [PDF]

open access: yes, 2008
In this work we investigated the performance of aluminium nitride (AlN)-based solidly mounted resonators (SMR) made with iridium (Ir) bottom electrodes. Ir/AlN/metal stacks were grown on top of insulating Bragg mirrors composed of alternate λ/4 layers of

Carbon nanotube forests as top electrode in electroacoustic resonators [PDF]

open access: yes, 2015
We grow carbon nanotube forests on piezoelectric AlN films and fabricate and characterize nanotube-based solidly mounted bulk acoustic wave resonators employing the forests as the top electrode material. The devices show values for quality factor at anti-

Third-Harmonic and intermodulation distortion in bulk acoustic-wave resonators [PDF]

open access: yes, 2019
This article discusses on the measured third-order intermodulation (IMD3) products and third harmonics (H3) appearing in a set of six different solidly mounted resonators (SMR) and bulk acoustic-wave (BAW) resonators with different shapes and stack ...
