Oscillators

Oscillators are devices that generate repetitive signals with constant amplitude, frequency, and phase, and are widely used in numerous applications. A commonly used oscillator is the AX7DAF4-910.0000C, which is a direct digital synthesis frequency synthesizer with built-in digital frequency storage and control.

Application Field of the AX7DAF4-910.0000C

The AX7DAF4-910.0000C is a wideband oscillator used primarily in radio communications systems, such as in commercial mobile radio systems, radar systems, navigation systems, and satellite communication systems. It is also used in defense applications, such as in electronic countermeasures and missile guidance systems. Furthermore, this oscillator is used in consumer products, such as cellular phones, wireless networks, and personal digital assistants.

Working Principle of the AX7DAF4-910.0000C

The AX7DAF4-910.0000C is an adjustable, wideband frequency synthesizer that uses digital frequency storage and control. Its frequency can be adjusted manually or programmed automatically over a wide frequency range of 0 MHz to 2.5 GHz. It is capable of synthesizing thousands of frequency steps with a resolution of 0.01 Hz.The oscillator operates in two phases; the set phase and the synthesized phase. In the set phase, the user sets the desired frequency at which the oscillator should operate. The desired frequency is fed to a digital control unit, which then outputs a signal to a phase-locked loop. The phase-locked loop uses this signal to generate and regulate the frequency of the oscillator. In the synthesized phase, the oscillator generates a signal at the set frequency. This signal is then fed to the output of the oscillator.The AX7DAF4-910.0000C is a direct digital synthesis frequency synthesizer, which features a low profile, small size, low power consumption, and excellent stability. In addition, it offers wide frequency coverage, fast switching, and high linearity over the entire frequency range.

Conclusion

The AX7DAF4-910.0000C is an adjustable, wideband, digital frequency synthesizer with low power consumption and high linearity performance. Its frequency can be adjusted manually or programmed automatically over a wide frequency range of 0 MHz to 2.5 GHz. This oscillator is widely used in numerous applications, such as radio communications, radar systems, navigation systems, and satellite communication systems.
