Oscillators: 520T25IT16M3677

Application Field

520T25IT16M3677 is an oscillator belonging to the family of voltage-controlled oscillators (VCOs). Its main application is for use in radio systems, notably cellular systems. The 520T25IT16M3677 will be used as part of the radio transceiver\'s local oscillator (LO) and as such it can be integrated with other components into a single multi-function package that is tuned to a certain frequency within a certain range. Another application of the 520T25IT16M3677 is in a frequency synthesizer, where it is used to generate high-frequencies to enable the separation of information from the signal.

Working Principle

The 520T25IT16M3677 is a voltage-controlled oscillator (VCO) which means its output frequency can be controlled by a voltage. The 520T25IT16M3677 is a voltage controlled VCO that exhibits a linear variation of frequency with respect to voltage. That is, the output frequency of the VCO increases linearly with the input voltage. The characteristic of the frequency-voltage conversion is a function of the electronic components used in the VCO design, in particular, the proportions of inductance to capacitance. As a result, an increase in the DC supply voltage will cause an increase in frequency until the maximum set frequency is reached.

When operating in an oscillator circuit, the 520T25IT16M3677 acts as an amplifier, where the output signal generated at the VCO output is fed back to its input amplifying it and producing an oscillation. The frequency of the oscillation is determined by the amount of feedback given to it. Usually, a resistor and a capacitor are placed in series, connected between the output and the input of the VCO. This forms a phase shift network which provides a 180-degree phase shift. This phase shift is enough to cause the oscillation, as the output signal is fed back to the input in an inversely proportional way.

By actively controlling the voltage at the input of the 520T25IT16M3677, it is possible to vary the voltage of the VCO output over a specified range. This voltage can be used to tune the output frequency of the 520T25IT16M3677 within its range of operation. Also, the 520T25IT16M3677 includes an integrated temperature compensation circuitry, which makes its operation temperature independent, allowing it to maintain a stable frequency over a wide range of temperatures.

In summary, the 520T25IT16M3677 is a voltage-controlled oscillator used to generate tailored frequencies within a wide range. It has excellent temperature stability, and its frequency characteristics and characteristics can be easily varied by simply controlling the DC voltage applied to it. In radio systems, it is mainly used in the local oscillator circuit to generate frequency separation between incoming and outgoing signals.
