GL080F23CET Application Field and Working Principle

Crystals are ubiquitous and play a significant role in the modern technology. Among many different types of crystals, GL080F23CET is a kind ofElectrical Tuning Crystal (ET) that is widely used around the world. In this article, the main application field, working principle and the engineering application of GL080F23CET is discussed. The main application field ofGL080F23CET is frequency control. It can be used to produce variable frequency signals and precisely control frequency in radio frequencies. The radio frequency signals can be used to modulate some information and create communication messages between distant objects. At the beginning andfinish of every time slot of access, the variable frequency signal generated by GL080F23CET can be used as an identification key or modification control signal. GL080F23CET can also be used in frequency standard source regulation in communications, navigation, remote sensing and instrumentation. GL080F23CET consists of an oscillator and a tuning circuit. Two electrodes and the oscillator medium are the main components of the oscillator. The tuning circuit is mainly composed of a quartz crystal and an inductor. When the magnetic field of an external oscillator is applied, the quartz crystal vibrates. The oscillator produces an alternating current, based on the positive and negative of the crystal elements. The oscillation frequency passes through to the tuning capacitors, and then to the tuned circuit. The oscillation frequency has a direct correlation with the external magnetic field and is influenced by the tuning capacitor. The fixed frequency is the response of the quartz crystal, which is the result of changes in the state. Under normal circumstances, the amplitude and frequency of the output signal from the oscillator do not change with the applied voltage or the temperature change. This is due to the low internal loss of the quartz crystal, the low temperature dependence of the oscillation frequency, the high stability of the excitation current and the excellent environmental stability. This feature makesGL080F23CET much more flexible, precise, and more durable in wide conditions. In terms of engineering applications, GL080F23CET is characterized as small size, low cost, less power consumption, and ease of manufacture. It is widely used in mobile phones and pagers,tuning of transmitters and receivers, electronic clocks, stabilized laser light sources and digital products. For example, GL080F23CET can be used to synchronize the cellular phone transmission and reception frequency, to stabilize the frequency output of tranceiver, and to adjust the variable oscillators in digital products. GL080F23CET is sometimes used to detect and shift the resonance frequency of vibration or sound. The corresponding frequency shift of the quartz crystal can be used to determine the displacement of the measured object and other parameters. This application can be seen in quartz crystal microbalances and quartz crystal resonant mass analyzers. To sum up, GL080F23CET plays significant roles in the modern technology. Its application field is frequency control and the working principle is through oscillator and tuning circuit. It is characterized as small size, low cost, less power consumption, and ease of manufacture and can be used in communication, navigation, remote sensing, instrumentation, cellular phone, digital products, etc.
