Raising the Q's of Piezoelectric Resonators

Methods for raising the Q's of piezoelectric resonators will be described, including the use of capacitive piezoelectric transducers and Q-boosting by mechanical coupling into arrays. Measured resonator performance metrics are then compared with the needs of front-end RF channel-selecting filters. These are then evaluated against the latest filter achievements using purely capacitive transduction.
