For usage in surface acoustic wave applications, langasite wafers are substrates made from a single crystal of the material.These wafers are often stated as having a reference flat and a 3″ diameter.The customer specifies the wafer orientation depending on the desired component performance parameters.
Polishing creates a high-quality, low-damage surface on one key surface.For the purpose of dampening undesirable vibration modes, the reverse side is often lapped to a rougher finish.
The current innovation, which relates to the field of electro-optics, can be applied to acousto-electronic frequency selection tools that use both surface and bulk acoustic waves.
A single crystal of lanthanum gallium silicate that is stoichiometrically organized and has a diameter greater than 75 mm and a weight greater than 3.5 kg is an object of the present invention. The creation of a single crystal with the following crystal orientation will require the development of an industrial technique.
The disk’s longitudinal axis is sliced at a 90-degree angle, producing a frequency temperature coefficient value of zero. Langasite wafer and its production processtechnical subject Wireless electronics, comprising surface and bulk acoustic waves, are a subject of the current innovation.
Application to acousto-electronic devices that use volume acoustic waves to pick frequencies You can make it work.Background SAW and VAW devices have significant promise for creating piezoelectric crystals with precisely controlled properties and costs thanks to new materials.
Including the creation of cutting-edge technology. Langasite has a number of unique characteristics. useful for offering compact size selecting devices for current wireless electronics equipment It has turned out to be an exciting piezoelectric substance.
In other words, the langasite crystal has a higher Q-factor than quartz and a higher dielectric constant than barlinite.are superior.The electromechanical coupling coefficient is established at a reasonable value by the triclinic symmetry of the system.
The Global Langasite Wafer market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Suitable for bulk and surface acoustic wave devices. High thermal stability at up to 900 °C. an elevated electromechanical coupling factor. Wafers have a diameter of 6-76.2mm. permits the existence of intercepts with low or even negative frequency temperature coefficients.
Some excellent characteristics of the langasite crystal include a stronger electromechanical coupling factor than quartz and the absence of a phase transition from ambient temperature to melt point. the crystal langasite’s characteristics
