Working Principle of AST3TQ-26.000MHZ-5

The AST3TQ-26.000MHZ-5 oscillator works on the principle of negative resistance. When a DC current is supplied to the oscillator, it produces an AC current signal with a specific frequency. The AC current signal then passes through a capacitor, which acts as a filter and limits the frequency of the signal. The filtered signal is then fed back to the oscillator, where it produces the same frequency as the original signal. This process is repeated, resulting in a stable signal with a specific frequency.The frequency of the signal is determined by the values of the components used, such as the frequency determining capacitors, the inductor, and the feedback resistors. The value of the feedback resistor determines the voltage gain, while the frequency capacitors and inductor determine the frequency of the output signal.

Conclusion

The AST3TQ-26.000MHZ-5 oscillator is a high frequency oscillator used for tuning circuits, closed loop systems, communication links, and signal generators. It works on the principle of negative resistance and produces a constant frequency with minimal phase noise and low signal-to-noise ratio. The frequency of the output signal is determined by the values of the components used and can be adjusted by varying these values. The AST3TQ-26.000MHZ-5 oscillator is a reliable and cost-effective solution for a variety of applications.
