An oscillator is an electronic resonator, which produces an alternating signal with a frequency that is determined by the components used in its design. Generally, an oscillator is constructed with two active devices as well as several passive components. Among the active devices, the most popular type is the Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) due to its high reliability and low cost.

The 579S307CAT oscillator is designed to provide a reliable and stable signal with low noise and signal distortion. It has been widely used in home audiovisual systems, car audio systems, public audiovisual systems, and military radar systems. Furthermore, the 579S307CAT oscillator has excellent temperature characteristics and is suitable for unfavorable temperature conditions.

The 579S307CAT oscillator utilizes the FETs as the active devices and the passive components include inductors, capacitors, and resistors. At the heart of the oscillator’s design, there is a pair of complimentary MOSFETs working in the Class A mode where the drain source current does not change with the change of the input signal level. Therefore, a stable output is kept even in the presence of the noise.

The working principles of the 579S307CAT oscillator can be explained in terms of the resonance properties of LC resonators. In this type of oscillator, two inverting operational amplifiers are connected in series and the output of one is fed back to the input of another. These two amplifiers form a Wheatstone bridge circuit with two inductors and two capacitors.

When a driving voltage is applied to the bridge circuit, a current is induced. This current flows through the two inductors and capacitors, establishing a feedback loop. Since the current is applied to the bridge circuit continuously, the oscillation will go on indefinitely. The resonant frequency of such a circuit is determined by the value of the inductors and capacitors used in the circuit.

The 579S307CAT oscillator can be used to generate a stable and continuous signal with low noise and signal distortion. The oscillator uses FETs as the active devices and incorporates two inverting operational amplifiers in the Wheatstone bridge circuit. The output frequency of the oscillator is determined by the value of the inductors and capacitors used in the circuit.
