Oscillators are electronic circuits designed to generate electrical signals regularly repeating at excited frequencies. There are many types of oscillators most of which are categorized by their method of generating the central signal. Their primary application is circuit timing and signal generation. SIT1602BI-73-18S-66.666600D is one of the oscillators whose application field and working principle will be outlined in this paper.

The SIT1602BI-73-18S-66.666600D saturable inductance oscillator is designed for the manufacturing of local oscillators used in commercial satellite television receivers. The signal produced by this oscillator is a continuous sine wave with minimal distortion and its output frequency is controlled by a digital tuning process. This oscillator provides precise control and cost-effective gain structure in a compact package.

The core components of SIT1602BI-73-18S-66.666600D are two transformer windings, two capacitors, a bipolar transistor, and an inductor. The oscillator works by alternately saturating and de-saturating the inductor. The saturation cycle is self-repeating and the frequency is determined mainly by the inductance, the capacitor values and the transistor\'s gain. The transformer windings provide a high-impedance output signal, allowing the oscillator to be used in many different applications.

As for its functioning mechanism, when the bipolar transistor is in saturation, the current flow is limited by the two capacitors in parallel, thus controlling the frequency. When the transistor switches to de-stenation, the current flow is limited by the series connection of the two capacitors and provides a large magnitude of current in the opposite direction. As the current builds up, an oscillating sinusoidal waveform is established which continues for as long as the transistor is switching from saturation to de-stenation.

The SIT1602BI-73-18S-66.666600D oscillator is commonly used in the field of satellite television receivers. It is used to produce a local oscillating signal for down converters that converts high frequency signals to lower frequency signals and then upconverts the acquired signal to the original frequency. The oscillator\'s output signal is a continuous sine wave with minimal distortion because it is designed to have a constant frequency and amplitude over a wide range of input voltages and temperatures.

The SIT1602BI-73-18S-66.666600D oscillator is an essential component in the manufacturing of satellite television receivers, as it can generate oscillating signals with precise accuracy and at minimum cost. This oscillator is designed to provide high-impedance output signals and it has the ability to self-regulate its frequency and ensure that the oscillations remain within a predetermined range, allowing it to be used in many different applications. Oscillators like the SIT1602BI-73-18S-66.666600D are essential for signal acquisition in many different radio frequencies.
