A Review of Piezoelectric Bulk Acoustic Wave (BAW) Resonator and Filter Technology

#5G #Filters #BAW #Q-factor #TCF #Spurious

Hybrid presentation by Dr. David A. Feld from Skyworks


A review of piezoelectric BAW filter technology will be presented focusing on the resonator technology comprising the filters. The presentation will discuss the modeling of frequency and bandwidth selection, spurious resonance suppression, and harmonic emissions. Resonator stored energy, Q factor, temperature coefficient, and power characterization will be discussed as well as the scaling of BAW filters to low and high frequencies. BAW filter technology will also be compared to other filtering technologies.
