Crystals are essential components of electronic devices. They are used in radio frequency and microwave communication, timers, oscillators, receivers, and signal conversion applications. The 8Y-27.120MAHE-T crystal is a low-cost, high-stability crystal designed for operation in the Industrial, Scientific, and Medical (ISM) frequency band. It has a center frequency of 915 MHz and a maximum tuning voltage of up to 1 V.Working principleThe 8Y-27.120MAHE-T crystal oscillator works on the principle that when an electric current is applied to a piece of crystal, it creates vibrations within the crystal lattice. These vibrations radiate outward as a series of sound waves, which are then picked up as an electrical signal by an amplifier. The frequency of the generated signal is dependent on the type of crystal being used. When the crystal oscillator is activated, an AC voltage of the resonant frequency is applied across the crystal. This causes it to vibrate at its resonant frequency for a period of time, during which it produces a frequency-stable oscillating signal. This signal can then be fed into an amplifier to generate the desired output frequency.Application fieldThe 8Y-27.120MAHE-T crystal is commonly used in the ISM frequency band, which covers a range of several hundred megahertz up to 1 GHz. It is ideal for applications such as medical imaging systems, industrial temperature sensors, security systems, and RFID tags. It is also capable of supporting wide-band FM/AM broadcast receivers and high-speed data transfer over distances. Additionally, it can be used in combination with other components to create a phase-locked loop (PLL) frequency synthesiser. The 8Y-27.120MAHE-T crystal is also ideal for use in military, commercial and aerospace systems due to its extremely stable frequency and wide operating temperature range. It is suitable for high-precision timing, data communications, and precision frequency control applications.ConclusionThe 8Y-27.120MAHE-T crystal is a highly stable, low-cost crystal designed for electronic applications in the ISM frequency band. It works on the principle that an electrical current applied to a crystal causes vibrations within the crystal lattice, which then radiates outward as a series of sound waves. These vibrations can be picked up as an electrical signal and used for applications such as medical imaging systems, industrial temperature sensors, and RFID tags. Due to its high stability and wide operating temperature range, it is also suitable for use in aerospace, commercial, and military systems.
