Application Field

SIT1602BI-32-18N-65.000000X oscillator is used mainly in cellular base station systems that employ CDMA technology. It is also well suited for use in other applications such as Wi-Fi, WiMax, and other frequency control applications where demanding RF performance is required.

SIT1602BI-32-18N-65.000000X oscillator can be used in cellular base station systems as the key for automatic frequency control. This oscillator is reversible, meaning that its frequency can be controlled in both the frequency-up and frequency-down directions. It is also capable of overcoming frequency offsets caused by temperature fluctuations, the aging of components, or characteristics of the environment.

Working Principle

The working principle of SIT1602BI-32-18N-65.000000X oscillator is based on the use of a varactor diode to enable frequency tuning. Varactor diodes, also known as varicap or variable capacitance diodes, are semiconductor diodes which have the ability to store electrical charge. Their capacitance can be controlled by an external voltage. The oscillator uses this ability to enable frequency tuning.

The oscillator is composed of two main components, the active device, which is the varactor diode, and the passive device, which is an inductor. An oscillation is triggered when a counter electric field is established between the active and passive components. This arrangement forms a “tank circuit” which oscillates at a frequency determined by its component values. The frequency can then be adjusted by applying a voltage to the varactor diode, which causes the inductance to change.

Conclusion

SIT1602BI-32-18N-65.000000X oscillator is a voltage controlled oscillator that is tailored to provide medium and small signal applications for cellular base station systems based on CDMA technology. It is used mainly in cellular base station systems that employ CDMA technology and for other frequency control applications requiring demanding RF performance. Its working principle is based on the use of a varactor diode, which enables the frequency of the oscillator to be tuned with applied voltage.
