Crystals have been an integral part of modern technology and are widely used in various industries, from medical devices to watches and cell phones. The AT-20.500MDHQ-T is a crystal that can be leveraged to serve many purposes. This article will discuss the various applications and working principle of this quartz crystal.

The AT-20.500MDHQ-T is a ceramic-packaged, miniature power quartz crystal from Abracon. It has an operating frequency range of 20.000-20.500MHz and a frequency stability of ± 100ppm for an operating temperature range of -20 to +70°C. It is designed to be used in applications requiring precision frequency or timing control. This crystal can be found in wireless modules, radio receivers, frequency counters, and FM and AM radio systems, as well as other electronic or oscillator circuits.

Working Principle of the AT-20.500MDHQ-T

The AT-20.500MDHQ-T works on the principle that a quartz crystal exhibits a unique and consistent frequency when exposed to an electrical field. The crystal is cut in a specific shape and vibrates at one particular frequency. The crystal is then oscillated between two electrodes at the same frequency. This oscillation is then converted into an electrical signal, which can be used to generate a precise and accurate clock signal.

The AT-20.500MDHQ-T is a cut quartz crystal with a thickness of 0.2mm. This crystal operates in a parallel resonant mode, which generates two frequencies for each frequency band, a fundamental and its overtone. The crystal can also be temperature compensated for better frequency stability or used in continuous mode. It has a low equivalent series resistance (ESR) and is designed to consume minimal power.

Applications of the AT-20.500MDHQ-T

The AT-20.500MDHQ-T is used in numerous types of electronic equipment. It can be found in electronic navigational and communications systems, motors, clocks and timers, audio systems, optical readers, industrial instrumentation, and ham radios. It is also used in wired and wireless networks, such as in smart grids, Wi-Fi networks, and satellite navigation systems.

The AT-20.500MDHQ-T crystal is also used in precision frequency control and timing systems. It can be used to synchronize pulses in high-speed communications systems, measure frequencies, or set dynamic monitoring protocols. This quartz crystal is also capable of providing very accurate long-term frequency control and consistent timing signals.

The AT-20.500MDHQ-T is an excellent choice for use in cost-sensitive applications, as it consumes very low power and has low ESR. As it is supplied in a ceramic package, the crystal is durable and can withstand most environmental conditions. The AT-20.500MDHQ-T is also easy to integrate into any system, making it a popular choice for many engineers.

In conclusion, the AT-20.500MDHQ-T is a precision crystal used in a wide range of applications. It operates on the principle that quartz crystals generate unique, consistent frequencies when exposed to an electric field. The crystal is highly reliable, consumes minimal power, and is relatively inexpensive. It is an ideal choice for applications requiring precision frequency control and timing.
