Oscillators

Oscillators are electronic components that generate a periodic electrical signal. They are most commonly used in the form of voltage-controlled oscillators (VCOs), which can be used to control frequency, amplitude, and phase. The AX7PAF1-1268.7000C oscillator is an example of a VCO.

Description

The AX7PAF1-1268.7000C oscillator is an analog voltage-controlled oscillator (VCO), which operates at 1268.7000 MHz. Its frequency range is 6 to 28 V, allowing it to be compatible with a variety of applications. It features a high frequency stability of 0.10 ppm/C, low phase noise of -156 dBc/Hz at 1 kHz offset, and a low current consumption of 66 mA.

Application Field

The AX7PAF1-1268.7000C oscillator is mainly used in the following applications:

• Wireless communications equipment.
• Radar systems.
• Test equipment.
• Ground station equipment.
• Ground navigation equipment.

Working Principle

The working principle of an oscillator is based on the theory of positive feedback. Positive feedback occurs when a portion of the output is fed back to the input, creating a loop that reinforces the signal. When the output is fed back to the input of the oscillator, it amplifies the signal. This causes the signal to oscillate at a certain frequency.

The AX7PAF1-1268.7000C oscillator works by injecting a current into the circuit, which produces oscillations of a certain frequency. The frequency of these oscillations is determined by the frequency-controlling elements, which are typically variable inductors and capacitors. The frequency of the oscillations can be tuned by adjusting the inductors or capacitors.

The AX7PAF1-1268.7000C oscillator also has a temperature compensation circuit, which helps to ensure the stability of the frequency over a wide temperature range. It also has low phase noise, which reduces the amount of interference created by the oscillator.

Conclusion

The AX7PAF1-1268.7000C oscillator is a voltage-controlled oscillator that operates at 1268.7000 MHz and is used in a variety of applications. It features a high frequency stability, low phase noise, and a low current consumption. The working principle of the oscillator is based on the theory of positive feedback and it uses variable inductors and capacitors to control the frequency of the oscillations.
