Oscillators

An oscillator is an electronic circuit that produces repeated, periodic signals, such as acoustic or radio waves. The most common type of oscillator is the alternating current (AC) oscillator, which generates sine waves. The ABLJO-V-200.000MHZ oscillator is an example of such an oscillator, and its application field and working principle are outlined below.

Application Field

The ABLJO-V is an oscillator used mainly in radio communication field. This oscillator generates signals in the range of 2 MHz to 200 MHz, with a frequency selection of 100 kHz and a step of 1 k. With this frequency range, it can be used for various applications, including FM and television broadcasting, two-way radio communication, cellular communication, and even satellite communication.

Working Principle

At the heart of the ABLJO-V-200.000MHZ oscillator is an electronic oscillator circuit. This circuit uses capacitors and resistors to generate oscillations with a specific frequency. The frequency of the oscillation is determined by the configuration of the components. This oscillator uses an adjustable voltage-controlled oscillator (VCO) circuit, which is a type of resonant circuit. The VCO circuit generates a steady and accurate signal with a tunable frequency, making it ideal for radio communication.

The ABLJO-V-200.000MHZ also utilizes a high-frequency amplifier, which amplifies the clean signal from the VCO circuit. This amplified signal is then sent to the output of the oscillator, where it can be used for radio transmission purposes. The signal also passes through a bandpass filter before being sent to the output, which helps to reduce interference from other signals in the frequency range.

The ABLJO-V-200.000MHZ is also equipped with a temperature compensation circuit, which helps to keep the oscillator running at a constant frequency even in extreme temperatures. This is critical for radio communication, as the oscillator must be able to maintain its frequency even when exposed to high temperatures.

Conclusion

The ABLJO-V-200.000MHZ is an AC oscillator used mainly in the radio communication field. Its main application is to generate a signal with a range of 2 MHz to 200 MHz. The oscillator\'s circuit uses a VCO, amplifier, and bandpass filter to generate a clean, accurate signal. Additionally, it is equipped with a temperature compensation circuit, allowing it to operate consistently in extreme temperatures.
