Oscillators

An oscillator, simply said, is an electronic device which oscillates at a given frequency and amplitudes. In this article we will discuss about an oscillator called the ASG-P-V-A-491.520MHZ-T.

Application Field

The ASG-P-V-A-491.520MHZ-T oscillator is primarily used in radio communications, as a local oscillator for up/down converters in radio receivers and transmitters. It is also used in communication systems, such as television transmission, wireless applications, radio broadcast equipment, radar systems and electronic warfare.

The oscillator is often chosen for its exceptional output voltage and low phase-noise characteristics. Its frequency range is from 400MHz to 600MHz, giving it increased flexibility when operating radio communication systems. Additionally, it offers excellent stability in the form of a long term drift performance, allowing it to serve over longer periods of time.

Working Principle

The ASG-P-V-A-491.520MHZ-T oscillator essentially functions using the resonance of quartz, with a metal plate connected to the quartz forming a capacitance. When an electric signal is applied, this capacitance changes its state, causing the quartz to oscillate at a predetermined frequency. As these oscillations occur, they are detected and reproduced via the transformer.

The oscillator uses a voltage-controlled oscillator (VCO) to control the frequency, by adjusting the voltage of the quartz. The voltage is applied to the electric field which then produces an electric current in the quartz. This causes the quartz to produce a resonant frequency, which can be further increased or decreased depending on the voltage applied.

The oscillator also has an internal amplifier to boost the signal output, as well as a low-noise frequency synthesizer (LNFS) to increase the stability of the output. This combination of features makes the ASG-P-V-A-491.520MHZ-T an ideal choice for radio communications and other, similar, applications.

In conclusion, the ASG-P-V-A-491.520MHZ-T oscillator is a highly versatile and reliable choice for a range of applications such as radio communication systems, television transmission, electronic warfare and more. It offers excellent stability in a wide frequency range, and its internal amplifier and LNFS allow for increased output and low phase noise.
