The crystals have a variety of applications. The most common use is in the construction of electronics, where they are used as capacitors and transistors. In addition, they may be used for high-frequency oscillators, oscillators, frequency converters, and voltage regulators.
Crystals can also be used for radio-frequency (RF) signal generation and detection. They are particularly useful in high-frequency applications that require high stability and accuracy over a wide temperature range. For example, crystal frequency standards are used in many types of communications equipment.
When used as an oscillator or frequency converter, the crystal operates by absorbing energy from its own resonant circuit and reemitting it at a frequency determined by its size and shape. This process results in very low phase noise due to the lack of thermal excitation.
