文摘
- •
Novel design of lateral electric field excited piezoelectric resonator is offered.
- •
New method of suppression of parasitic oscillations in such resonators is invented.
- •
Separation of electrodes holder and piezoelectric plate suppresses parasitic modes.
- •
For composite resonator Q-factor for series/parallel resonances is equal to 15,000.
- •
Composite resonator is easy-to-development of liquid sensor without radiation loss.
