Introduction

An oscillator is a circuit or device that produces a repetitive electrical signal of a certain frequency. Oscillators are used in a wide variety of applications, providing precision timing, reliable operation, and stability in oscillator frequency and amplitude. One type of oscillator, the AX7HCF1-470.0000C oscillator, is a miniature, high frequency oscillator designed to provide stable, crystal-controlled frequencies over a wide temperature range. The following sections will discuss the application field and working principle of the AX7HCF1-470.0000C oscillator.

Application Field

The AX7HCF1-470.0000C oscillator is designed to provide a low-cost, high performance option for frequency ranges up to 145MHz. It is ideal for controlling, generating, and providing frequency reference for radio frequency (RF) and telecommunication systems. The device can be used in both on-board and off-board applications, and offers a low ripple, high gain, low noise output signal.The AX7HCF1-470.0000C oscillator can be used as an exact frequency reference in mobile base station, digital data radios, and other complex RF systems. It can also be utilized in satellite receivers, GPS receivers, and microwave radio links. In addition, the device is suitable for use in low noise RF components, including radio receivers, television receivers, modems, and iambic keyed antennas.

Working Principle

The AX7HCF1-470.0000C oscillator works by using a crystal-controlled oscillator to generate a precise frequency signal. A quartz crystal, typically 18MHz, is connected to a resonant tank circuit that oscillates at the crystal\'s frequency. The oscillator amplifies the signal, and then the amplified signal is output from a specially designed coaxial cable.The oscillator consists of two components: an amplifier and a frequency discriminator. The amplifier takes in the incoming signal from the crystal and amplifies it to a pre-determined level. This amplified signal is then passed through the frequency discriminator which checks to ensure that the frequency of the signal is at the same frequency as the crystal. If the signal is not at the expected frequency, a corrective signal is sent to the amplifier, adjusting the oscillator output frequency to the desired value.

Conclusion

The AX7HCF1-470.0000C oscillator is a low-cost, high performance oscillator designed to generate and control crystal-controlled frequencies up to 145MHz. It is ideal for RF and telecommunication systems, as well as for use in radio receivers, television receivers, modems, and other low noise RF components. It works by using a crystal-controlled oscillator, an amplifier, and a frequency discriminator to generate a precise frequency output signal.
