Oscillators: AX7DCF4-1090.0000T application field and working principle

Oscillators refers to the basic electronic components that generates a periodic, oscillating signal through an external electric circuit. In particular, oscillators are used to generate signals or maintain a stable frequency in communication systems and radio networks. Such oscillators are defined by the frequency range of the generated signal, the operating voltage and the output waveform, depending on the desired application. The AX7DCF4-1090.0000T oscillator is a component with a frequency range from 1000 MHz to 1090 MHz, and is capable of working with a voltage of 5 V. Its output waveform is sine-like.

Application Field

The AX7DCF4-1090.0000T oscillator is an electronic component designed for applications in radio frequency and communication systems. Its applications include cellular systems, Bluetooth, Wi-Fi, and GPS navigation. This oscillator can be used for transmitting signals with a frequency of 1000 MHz to 1090 MHz.

Working Principle

The AX7DCF4-1090.0000T oscillator is based on the feedback oscillator circuit with a negative resistance component as a feedback element. In the circuit, the negative resistance element is an active transistor with an inductor connected in series. The inductor is connected to a crystal that is responsible for providing the reference frequency. The transconductance amplifier is connected in series between the inductor and the capacitor. This amplifier amplifies the output signal and acts as an energy feed and energy storage device.

The output signal passes through the amplifier, and then goes back to the negative resistance element. The negative resistance element is capacitive, and it takes away some energy from the signal at each feedback cycle. The signal then passes through the crystal and inductor, and back through the amplifier, thus amplifying the signal at each feedback cycle. This continuous feedback leads to the building up of the signal, which is eventually emitted out as the output signal.

The active transistor ensures that the negative resistance element is able to properly perform its task of oscillation. The amount of energy taken away by the negative resistance element at each feedback cycle can be adjusted by regulating the transistor’s operating point with the help of a potentiometer and associated hardware. This allows the energy to be precisely regulated, thus providing an output signal with a predetermined frequency.

Conclusion

In conclusion, the AX7DCF4-1090.0000T oscillator is a highly reliable component designed for applications in radio frequency and communication systems. It has a frequency range of 1000 MHz to 1090 MHz, and operates with a voltage of 5 V.
