Introduction

A 9B-3.579545MBBK-B Crystal is a type of crystal that is used in the application of radio communication and other similar fields. It is widely used in wireless communication networks and other specialized applications. It is also used in the control of frequency synthesis. The 9B-3.579545MBBK-B crystal is a type of quartz crystal and offers superior frequency stability, low jitter and a very high Q-factor. It is suited for both low and high frequency applications which makes it a popular choice for radio and wireless communication.

Structure

The 9B-3.579545MBBK-B Crystal consists of an AT-cut quartz plate surrounded by electrodes. The AT-cut is an angle-cut quartz plate, which is cut to a specific angle and afterwards processed to a high degree of accuracy. The plate of the crystal is placed between two electrodes which are composed of gold or aluminum and are then bonded to the quartz plate. This increases the conductivity and ensures a better connection between the quartz and the electrodes. The bond wires and the electrodes connect the quartz to the circuit which is mounted on the same package. The package also includes necessary components such as a temperature compensating capacitor, a trimmer capacitor, etc.

Application Field and Working Principle

The 9B-3.579545MBBK-B crystal is mainly used in radio communication and other similar applications. It is an economical and efficient frequency generator. The crystal operates by converting input electrical energy into mechanical energy, while the reverse transformation of mechanical energy into electrical energy is equally possible. The working principle of the 9B-3.579545MBBK-B crystal is based on the piezoelectric effect. This effect causes a polarization of the crystal in response to an electric field. When an alternating electric field is applied to the crystal, it will vibrate back and forth at its own natural frequency. This frequency is determined by the shape and size of the crystal and serves as an oscillator for the electrical circuit. The 9B-3.579545MBBK-B crystal is mainly used in wireless systems, local oscillators and frequency control modules. It is also used in RF/microwave communication receivers and transmitters, GSM and WCDMA radios, GPS navigation, medical imaging, and so on. The 9B-3.579545MBBK-B crystal is also very suited for use in military applications such as satellite communication systems and submarine communication. The wide frequency range, low phase noise and excellent accuracy make it an ideal choice for these applications.
