Oscillators

Oscillators are electrical circuits which generate and transfer signals to other circuits in the form of periodic waves of electrical current. Oscillators can take many forms and serve numerous applications. One type of oscillator is the ABNLO-81.920MHZ oscillator, which is commonly used in communications, instrumentation, and navigation. This article will discuss the application fields and working principles of this oscillator.

Application Fields

The ABNLO-81.920MHZ oscillator finds use in a range of application fields where an oscillator of its frequency is required. This includes radio communications for digital transmission systems and cell phones, test instruments and other measurement devices for calibration, and navigation devices, such as on ships and aircraft.

For radio communications, ABNLO-81.920MHZ oscillators are used to generate and transmit signals at 819.2MHz. As this is among the higher frequency bands, the oscillator can be used in applications for high-definition television broadcasting, satellite communications, and more. In test instruments and other measurement systems, the oscillator can be used for frequency reference or sweep oscillators, which are used to measure frequencies in different ranges.

When it comes to navigation, ABNLO-81.920MHZ oscillators are used in Most ship-borne Global Positioning System (GPS) receivers, as well as aircraft instruments, to provide accurate location and referencing data. These oscillators can generate pulses that are used to track positions in both aircraft and ships.

Working Principles

The ABNLO-81.920MHZ oscillator utilizes the principle of frequency multiplication to generate its output signal. A frequency doubler is employed to double the frequency of the input signal, which can be generated from quartz crystal oscillators or other oscillating circuits. At the same time, low-pass harmonic filters are used to eliminate harmonics and ensure that only the right frequency is generated.

The output of the frequency doubler is then fed into a tuned amplifier, where its amplitude is increased and its quality is improved. Additionally, the amplifier can be adjusted to regulate the frequency of the signal, allowing for fine tuning of the output to match the specific requirements of the application.

The ABNLO-81.920MHZ oscillator also features a DC power supply, which is used to provide the necessary power for all other components of the system. This power supply should be regulated to ensure that the oscillator performs reliably under various operating conditions.

Conclusion

The ABNLO-81.920MHZ oscillator is a versatile device which can be used to generate and transmit signals at 819.2MHz. It finds use in radio communications, test instruments, navigation systems, and many other applications. The oscillator works using the principle of frequency multiplication with signal amplification and filtering, as well as a regulated DC power supply.
