Manufacturer profiles with relevant production capability in China
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
Not customer reviews or live demand data. These dimensions support RFQ preparation and supplier evaluation.
These scores are example evaluation dimensions, not real customer ratings, country-specific buyer feedback, or live inquiry activity.
IDTs are essential components in surface acoustic wave (SAW) devices including filters, resonators, delay lines, and sensors used in telecommunications, RF systems, and signal processing applications.
Substrate materials like Lithium Niobate (LiNbO₃) offer high electromechanical coupling for broadband applications, while quartz provides excellent temperature stability and low loss for precision frequency control devices.
The IDT's operating frequency is primarily determined by the electrode finger spacing (pitch) and the acoustic velocity of the piezoelectric substrate, with typical ranges from MHz to several GHz depending on design parameters.
