Introduction

Crystals are among the most important materials used in advanced technology. This article discusses the application field and working principle of 7M-28.63636M_AMHE-T, a type of crystal grown with temperature compensated crystal oscillator(TCXO) technology.

History of Crystals

The development of crystals can be traced back to the late 19th century. Scientists of the time were able to grow quartz crystal by heating a solution of ammonium nitrate and ammonium sulphide. This process of growing quartz crystals was later named the Biquartz method. In the 1920s and 1930s, quartz crystals gained widespread use in radios and other electronic devices. The radio industry adopted crystal oscillators as efficient voltage regulators. By the 1950s, synthetic crystals such as rubies and sapphires had been developed by scientists, and these materials soon found applications in the burgeoning aerospace, defense and electronics industries.

Application of 7M-28.63636M_AMHE-T

7M-28.63636M_AMHE-T crystal is a temperature compensated crystal oscillator (TCXO), developed by 3M. This type of crystal is widely used in smartphones and other mobile devices that require precise timing and precise temperature control. The 7M-28.63636M_AMHE-T crystal is especially useful in cellular communication systems, GPS systems and radio applications due to its robust and reliable performance in extreme temperature conditions.

Working Principle of 7M-28.63636M_AMHE-T

The working principle of 7M-28.63636M_AMHE-T crystal is based on its construction and design. The 7M-28.63636M_AMHE-T crystal is composed of multiple layers of different materials. These layers are combined to enable periodic voltage changes when an alternating current is applied. This process generates a voltage wave that can then be used to create a periodic signal. The crystal oscillator utilizes an automatic temperature compensation (ATC) mechanism that accounts for thermal expansion and contraction. It relies on an oscillator circuit to maintain a constant amplitude of the output waveform. The design of the 7M-28.63636M_AMHE-T crystal ensures that it is capable of maintaining a precise frequency under varying temperatures.

Conclusion

In conclusion, the 7M-28.63636M_AMHE-T crystal is an important technology used in many mobile devices and electronic systems due to its accurate working principle and temperature compensation mechanism. It has been specifically designed to operate in extreme temperature conditions and thus can be used in a variety of applications. Crystal oscillators have been used since the late 19th century, and continue to be an essential building block for many present-day technologies.
