Crystals are one of the many technologies in electronic engineering. They have been used extensively in modern applications, including communication devices, medical devices, and more. AS-4.194304MAHE-B is a type of crystal specifically designed for radiofrequency applications. In this article, we will examine the application field and working principle of this type of crystal.

Applications of AS-4.194304MAHE-B Crystal

The AS-4.194304MAHE-B is an AT-Cut surface-mount crystal with a center frequency of 4.194304 MHz and a frequency tolerance as low as ±50 ppm. It is designed for applications such as radiofrequency communications, radiofrequency timing, radiofrequency control, and general-purpose frequency synthesis.

The crystal is highly resistant to EMI/RFI noise, so it is suitable for applications with high levels of electromagnetic interference such as cell phones, Bluetooth, and Wi-Fi devices. It also has a high Q factor, meaning that it can provide higher frequency stability. The crystal is also lead-free, so it is compliant with RoHS and other environmental regulations.

Due to its small size, the AS-4.194304MAHE-B can be used in a wide range of portable and miniature applications. It is available in both 3.2 x 1.1 mm and 2.5 x 0.88 mm packages, which make it suitable for space-constrained designs. The crystal is also RoHS-compliant and UL-approved, providing extra assurance of quality and dependability.

Working Principle of AS-4.194304MAHE-B

The AS-4.194304MAHE-B crystal works on the principles of piezoelectricity. The crystal is composed of a quartz crystal with two electrodes placed on opposite faces of the crystal. The quartz is cut in such a way that when it is subjected to an electric field, the crystal expands. This expansion causes the crystal to vibrate at a certain frequency, called its resonating frequency.

The crystal’s resonating frequency is determined by its shape and size. By controlling the shape and size of the crystal, manufacturers can achieve a specific resonating frequency. The AS-4.194304MAHE-B crystal is specifically designed to have a center frequency of 4.194304 MHz, and its frequency tolerance is as low as ±50 ppm.

Once the crystal is subjected to an electric field, it will vibrate at its resonating frequency, producing an output signal. This signal can then be used in electronic circuits for timing or synchronization applications. The crystal will continue to vibrate at its resonating frequency as long as the electric field is kept constant.

Conclusion

The AS-4.194304MAHE-B is a surface-mount AT-Cut crystal designed for RF applications. Its small size and frequency stability make it suitable for a wide range of mobile and miniature applications. The crystal works on the principles of piezoelectricity, vibrating at its resonating frequency when subjected to an electric field. This signal can then be used for timing and synchronization purposes.
