Product Description
8-inch Lithium Niobate Wafers for Surface Acoustic Wave Devices
High-performance 8-inch LiNbO3 wafers in 128°Y-cut and Z-cut orientations specifically engineered for surface acoustic wave (SAW) device manufacturing. These large-diameter wafers deliver exceptional electromechanical coupling coefficients and low propagation loss for advanced RF applications.
Material Properties
Lithium Niobate (LiNbO3) is a ferroelectric crystal with trigonal R3C hexagonal structure, featuring high electromechanical coupling coefficient and low propagation loss. SAW devices manufactured from these wafers can achieve bandwidths up to 50% with propagation velocities of 3400-4000m/s.
