Oscillators are electronic components that generate alternating currents or signals in a periodical manner. They are widely used in many applications across industries, from communications, computing, medical to automotive.One such oscillator is VG-4513CA 125.0000M-GGCT3. This article unravels how this oscillator functions and its application field.

VG-4513CA 125.0000M-GGCT3 Operating Principle

VG-4513CA 125.0000M-GGCT3 is a voltage-controlled oscillator (VCO) designed for different frequency generation. It is incorporated with considerable noise reduction in order to achieve low phase noise as well as small phase shifts. This oscillator typically consists of three main components: the power amplifier circuit, the oscillator circuit and the voltage-controlled oscillator circuit. The oscillator needs a steady supply of power to function, which is provided by the power amplifier circuit. Subsequently, it will allow the voltage-controlled oscillator to generate different frequencies.

The initial part of the oscillator circuit is an RC circuit formed by resistor and capacitor. Since capacitors lack frequency selection, a voltage-controlled oscillator is included in a single monolithic crystal after the RC circuit. This oscillator circuitry operate in low noise mode and reduces the thermal noise generated during the oscillation cycle. This oscillator also includes a frequency doubler, which helps in optimizing the RF resonator and achieving a wide frequency tuning range. It also helps to reduce the power consumption of the device.

At the core, there is a voltage-controlled oscillator, also known as the VCO. The VG-4513CA 125.0000M-GGCT3 oscillator operates almost similar to other VCOs. It relies on a tuned circuit-resonator with one end connected the the regulating input and other end being the output. It effectively works by the emitter-coupled transistor amplifying and demodulating the resonator’s signal into an alternating voltage. This alternating voltage then becomes the output signal.
