Crystals, or piezoelectric crystal resonators, are small in size and extremely stable in frequency. They are used extensively in radio receivers and transmitters, computers, TVs and telecom devices. ATS050A, is one of the typical crystal resonators. This article will discuss in more detail its application field and working principle.

ATS050A is a common piezoelectric crystal resonator widely used in communication and measured instruments. It has a frequency of 50.000MHz and the equivalent series resistance (ESR) of 40-60 ohms. It is widely used in low frequency communication equipment, including electronic test instrument, aviation, three ships, magnetic field, distance measuring, remote control, for navigation and other fields.

The working principle of ATS050A crystal resonator is based on the piezoelectric effect. The principle of piezoelectric effect is when mechanical strain or stress is applied to the crystal, an electric charge or voltage is generated. When an electric field is applied to the crystal, a mechanical stress or strain is generated. by applying an alternating electric field to the crystal, vibrations are developed, thus producing an oscillating electric field. This oscillating electric field is then used to generate radio signals with the help of a transducer.

ATS050A crystal resonator is composed of AT cut quartz crystal, two electrodes, a shell, and an insulating layer. The crystal and the electrodes are the main parts of the resonator, which determine the frequency of oscillation. The electrodes are usually made of gold or platinum alloy, while the shell is generally made of metal. The AT cut quartz crystal is cut and polished at a certain angle to form two faces with an angle of 54° between them.

When an AC current is applied, the quartz crystal will vibrate and generate an oscillating electric field. The frequency of the oscillating electric field is determined by the thickness and structure of the crystal, as well as the medium in which the crystal is placed, such as air or vacuum. ATS050A crystal resonator has a frequency of 50.000MHz and the equivalent series resistance (ESR) of 40-60 ohms. As the thickness of the quartz crystal increases, the frequency of the oscillating electric field decreases, and the reverse is true when the thickness decreases.

The ATS050A crystal resonator is typically used in the following applications:

• Wireless communication equipment: such as base station, telecommunication equipment, navigation device and other electronic communication equipments.
• Electronic test instruments: such as communication signal generator and signal meter.
• TV, FM radio, etc.
• RFID or other remote control and navigation systems.

In conclusion, ATS050A crystal resonator is a popular piezoelectric crystal resonator with a frequency of 50.000MHz and an equivalent series resistance (ESR) of 40-60 ohms. It is widely used in the fields of wireless communication equipment, electronic test instruments and navigation systems. It works based on the piezoelectric effect and relies on the thickness and structure of the crystal, as well as the medium in which it is placed, to determine the frequency of oscillation.
