  • Complementary switchable dual-mode bulk acoustic wave resonator and filter
    Patent number: 12620960
    Abstract: A laminated ScxAl1-xN BAW resonator with complementary-switchable operation in thickness extensional modes (TEl and TEN). The resonator comprises ferroelectric ScxAl1-xN layers alternatively stacked with metal electrodes, enabling independent polarization switching of each piezoelectric layer. Opting for unanimous or alternative poling of the ScxAl1-xN layers, the resonator can be switched to operate in two complementary states with either TEl or TEN active resonance modes of similarly large kt2.
