Product Description
Product Overview
4-inch DSP SSP Lithium Niobate (LiNbO3) wafers in 128Y-Cut and 36Y-Cut configurations, engineered specifically for Surface Acoustic Wave (SAW) filters and transducers. Lithium Niobate is a premium ferroelectric material valued for its exceptional electro-optic, nonlinear optical, and piezoelectric characteristics.
Material Properties & Applications
Lithium Niobate's superior properties make it an ideal material for optical waveguides, medium-to-low frequency SAW filters, and high-power, high-temperature resistant ultrasonic transducers.
