Third order intermodulation distortion in Film Bulk Acoustic Resonators at resonance and antiresonance [PDF]

2008 IEEE MTT-S International Microwave Symposium Digest, 2008
This paper presents recent measurements and modeling of the third order intermodulation products of a Film Bulk Acoustic Resonator (FBAR), for a various values of frequency spacing between driving tones. The frequency dependence of voltage and current in the acoustic branch rules out a voltage-dependent nonlinearity.

Tunable high-Q SAW resonator loaded on a changing capacitance [PDF]

Journal of Advanced Dielectrics, 2020
A tunable high-Q surface acoustic wave (SAW) resonator in the form of several parallel-connected interdigital transducers loaded on a varying capacitance on lithium niobate substrates was developed and studied. The working frequency range was 90–2450MHz.

Quasi-3D Model for Lateral Resonances on Homogeneous BAW Resonators

Micromachines, 2023
Lateral modes are responsible for the in-band spurious resonances that appear on BAW resonators, degrading the in-band filter response. In this work, a fast computational method based on the transmission line matrix (TLM) method is employed to model the ...
