About This Product
Langa site is mainly provided by Russia FOMOS or German crystal manufacturers.
■ Langa site crystal
It is a product based on the joint development of the Moscow State University and the Crystal Research Institute in the Soviet Union (Russia) in the early 1980s. Initially, it was studied as a laser optical application, but it has been found that there is no field that can be applied and can be applied to piezoelectric technology.
■ Applications
Langa site is the same crystal crystal as quartz.
It has about 2.7 times a piletelectric coefficient D11 of the crystal, so you can realize a very sensitive piezoelectric sensor. As a product that is applied and spreads by applying its piezoelectric properties, it is the role of the wireless frequency (RF) control element (resonator) and the filter. Other than that,
It is applied to the manufacturing of resonator as a crystal vibration.
As a filter, the electrical mechanical coefficient of the electrical mechanical coefficient is about 7%lower than the crystal quartz, and there are restrictions in the field of filter. However, this restriction can also manufacture only narrow band filters with the relative value of the currencies band to the center frequency of the filter up to 0.3%.
■ Filter application
The current digital signal processing method is widely used in transmission and receiving devices that impose the requirements for expanding the passing band of useful signals in the intermediate frequency (IF) amplifier, but when using quartz for the production of wide band filters. In addition, it is necessary to adjust the additional element (addition of an inductan coil) or a product size and weight data, and use a high K2EMC piletelectric material. There are currently Litao3 (lithium tantalate: LT) as these materials, which allows for a wide band filter.
However, in LT, the frequency temperature stability and quality coefficient (Q) of the resonator are low, the cumulative pass band value is within the range of 0.6 to 4.0%, and the application of the LT filter is limited. In order to realize filter in a relative currency band of 0.3 to 0.8%, a piezoelectric material with the intermediate characteristics of a crystal and lithium tantalate is required, and here is 0.3 to 0.85%due to the application of the lang sites crystal. A filter with a relative path band can be realized. A 0.8%resonator of this new frequency control oscillator can be designed.
