Crystals

Crystals are widely used in frequency control applications. Crystals in these applications come from physical model parameters such as shape, size, mass, and elasticity. It is important to pay attention to the model parameters when selecting the right crystal for a specific application. One of such crystal is the ABM8-20.000MHZ-18-D2Y-T. This article will focus on the application field and working principle of the crystal.The ABM8-20.000MHZ-18-D2Y-T crystal is used in radio frequency applications, particularly in WLAN, WiMAX and mobile base station applications. The crystal has a nominal frequency of 20.000MHz, with a allowable tolerance that can reach up to +/-10PPM. It is also suitable for use with high-frequency circuits that can reach up to 3.4GHz.The working principle of ABM8-20.000MHZ-18-D2Y-T crystal can be explained with a simple analogy of the impact of mechanical vibration on metal surfaces. When metal plates vibrate, they interact and create a resonance via air molecules. The same principle applies to a crystal, instead of air molecules, the crystal’s quartz way oscillates and interacts with other crystals. As a result, it emits resonances at certain frequencies.To ensure that the ABM8-20.000MHZ-18-D2Y-T crystal oscillates at a precise frequency, the crystals are coated with gold or silver. This coating functions as an electrical bridge between two crystals and helps them interact with each other. Furthermore, the crystal is also surrounded by a metal case which allows the crystal to be more precisely tuned.The ABM8-20.000MHZ-18-D2Y-T crystal’s applications range from traditional communication technologies such as public broadcasting, military communication, civil aviation communication, and satellite communication, to newer technologies such as the sharing economy and the Internet of Things. In general, the crystal is used to provide precise and stable frequency control in radio frequency circuits.In addition, the ABM8-20.000MHZ-18-D2Y-T crystal has a high temperature withstand range as well as a small footprint that makes it suitable for compact and small products. In addition, its robust design and tolerance of up to +/-10ppm make it suitable for use in various applications that require precise and stable frequency control.In summary, the ABM8-20.000MHZ-18-D2Y-T crystal is an ideal choice for radio frequency applications due to its small size, high temperature tolerance, and precise and stable frequency control. Its applications range from traditional communication technologies to newer technologies, making it a versatile and reliable choice for frequency control.
