Introduction to CWX825-125.0M Oscillators

CWX825-125.0M is a type of oscillator, which has multiple applications in various fields and works using a combination of two input signals. In this article, we will discuss the application field and working principle of CWX825-125.0M.

Application Field

CWX825-125.0M oscillators have several application fields, such as radio communication, microwave communication, and instrumentation. It is also used in medical equipment, optical communication, broadcast equipment, and signal processing systems. In addition, it plays an important role in motor control, power management, and power conversion systems.

Working Principle

The working principle of CWX825-125.0M oscillators is based on the combination of two inputs signals. The first input signal is a reference signal, which serves as the standard timebase for oscillation. The second signal is a control signal, which is used to change the frequency or period of oscillation.CWX825-125.0M oscillators utilize two transistors in their structure. One is the base transistor, which is used to modulate the reference signal. The other is the control transistor, which is used to vary the resonance frequency.The base transistor is connected to a capacitive voltage divider, which is used to extract the reference signal from the control signal. This signal is then fed to the base terminal of the control transistor. The emitter of the control transistor is then connected to the gate of the base transistor.When the reference signal changes, the capacitance of the voltage divider also changes, which in turn alters the base-emitter voltage and changes the bias of the control transistor. This in turn alters the resonance frequency of the oscillator, which is then fed back to the control signal. This feedback loop causes the oscillator to oscillate.The frequency or period of oscillation can be easily controlled by changing the reference signal. This makes the CWX825-125.0M oscillators very efficient and reliable.

Conclusion

In conclusion, CWX825-125.0M is a type of oscillator with multiple applications in different fields. It works by the combination of two input signals: a reference signal and a control signal. The reference signal is used to provide the standard timebase for oscillation, while the control signal is used to adjust the resonance frequency. The capacitive voltage divider is used to extract the reference signal, and the control transistor is used to vary the resonance frequency. Thus, the frequency or period of oscillation can be easily controlled by adjusting the reference signal, making the CWX825-125.0M oscillators very efficient and reliable.
