Crystals: 402F25012IDR Application Field and Working Principle

Crystals are crucial components of nearly all electronics and electrical systems. 402F25012IDR is a type of very small quartz crystal resonator, referred to as surface acoustic wave (SAW) resonator, that lies in the application field of radio frequency (RF) technology. In this article, we will discuss the application field of 402F25012IDR and explain how does it work.

Application Field of 402F25012IDR

The 402F25012IDR quartz crystal resonator has the size of 15.00mm*6.33mm*3.00mm and is being widely employed in a variety of different electrical and electronic systems. It is particularly useful in the application field of RF technology since it has excellent stability and equally good filtering performance. Furthermore, the 402F25012IDR also plays an integral role in the fields of digital and analog electronics since due to its exceptional accuracy and high repeatability, the device is used in frequency control and system verification.

Working Principle of 402F25012IDR

The 402F25012IDR quartz crystal resonator is made from a type of quartz crystal known as AT-cut quartz that is developed specifically for radio frequency use. The device has a solid quartz substrate and makes use of interdigital transducers that are situated between two or more electrodes on the surface of the quartz. These electrodes generate an AC electrical signal which produces a surface wave acoustic wave in the quartz known as a SAW. This wave is then sent through a specific filter section, thus controlling its frequency and selectivity.

The electrical wave then interacts with the quartz vibrator and the resonator detects this interaction, determining the frequency of that wave, allowing fluctuations to leave the wave unaffected. This wave is then turned into electrical input and output, which allows the device to accurately determine frequency and stability. An oscillator stage is further included, allowing the crystals to work even better as a frequency stabilized oscillator. The results are resonator with a very accurate and stable frequency.

Conclusion

In conclusion, the 402F25012IDR quartz crystal resonator is an exceptionally useful device in the application field of RF and digital electronics. Its excellent stability and accurate repeatability make it ideal for a variety of different applications.. The 402F25012IDR works by utilizing interdigital transducers on a quartz substrate and converts a surface acoustic wave into electrical input and output, allowing for frequency control and stability. The device is also perfectly suitable for use as a frequency-stabilized oscillator as it can accurately and reliably detect frequency.
