NJ-10M-6870

Oscillators are electromechanical or electrical devices that produce alternating electric current or voltage of a certain frequency. NJ-10M-6870 is a popular oscillator device in the field of electronics and communications. In this article, we will discuss the application fields and working principles of this type of oscillator.

Application Field

NJ-10M-6870 oscillators are mainly used in wireless communications and data transmission, including but not limited to GSM, CDMA, WCDMA, TDMA, etc. They can also be used in high-speed digital circuits, such as from 125MHz to 300MHz. Other application fields include electronic equipment, meter instrumentation, measurement devices, frequency synthesizers, and navigation systems.

Working Principle

NJ-10M-6870 oscillator uses a negative resistance device as its frequency determining element. Usually the negative resistance device consists of an amplifier, a resistor, a diode, and a capacitor. When the oscillator is in operation, the output signal will pass through the amplifier and the resistor then to the capacitor and diode, which form a feedback loop. The feedback loop determines the output frequency of the oscillator. By adjusting the amplifier\'s gain, the feedback strength, as well as other parameters, the frequency can be tuned.

NJ-10M-6870 is also equipped with temperature compensation circuit. The temperature compensation circuit provides a current signal that compensates the resistance and capacitance changes caused by temperature variation, ensuring that the output frequency stays at the desired frequency.

Conclusion

NJ-10M-6870 oscillators are widely used in communication systems and electronics circuits. Its working principle is relatively simple and by adjusting its parameters, it can be tuned to different frequency as desired. With its temperature compensation circuit, the oscillator can keep the output frequency stable over a wide temperature range.
