Varactor diode datasheet generator#

In frequency modulators they can be placed across the resonant element within the generator and the audio applied to the diode. Typically this might be provided under microprocessor control via a digital to analogue converter.ДЇrequency & phase modulators: Varactor diodes can be used in frequency and phase modulators. Again this can be controlled using a control voltage.

Tracking filters may be needed in receiver front end circuits where they enable the filters to track the incoming received signal frequency. RF filters: Using varactor diodes makes it possible to tune filters.The varactor diode is a key component within the voltage controlled oscillator.

In turn these can be used as FM demodulators or within frequency synthesizers. One major area is for the oscillator within phased locked loops. Voltage controlled oscillators, VCOs: Voltage controlled oscillators are used in many different RF designs.This gives them an almost unique capability and as a result varactor diodes are widely used within the RF industry.ДЄlthough varactor diodes or varicap diodes can be used many different circuits, they find uses in two main areas: They provide a method of varying the capacitance within a circuit by the application of a control voltage. Varactor diodes are widely used within many RF designs. The name varactor meaning variable reactor, or reactance, and varicap meaning variable capacitance (vari-cap). In fact the applications for varactor diodes are almost limitless and they are used in a host of different circuits for a variety of different circuit uses, for general electronic circuit design as well as RF design.ДЄlthough both names: varactor and varicap diode are used, they are both the same form of diode. Not only can varactor diodes be used for analogue control of a voltage, such as in a phase locked loop, but it can also be used in conjunction with microprocessors where a voltage can be generated digitally and then converted to an analogue voltage to control the diode by using a digital to analogue converter, ADC. These electronic componenta can be used in a whole variety of ways where a capacitance level needs to be controlled by a voltage. Varactor or varicap diodes are used mainly in radio frequency or RF circuits to provide voltage controlled variable capacitance.
