☑ Varactor Diode Details

A varactor diode also known with the names varicap diode varactor diode tuning diode is a p n junction diode which acts as a variable capacitor under varying reverse bias voltage across its terminals. The low resistance of these varactors makes them appropriate for high q resonators in wireless system vcos to frequencies over 10 ghz.

What Is A Varactor Diode Working And Characteristics

The area of the junction.

Varactor diode details. These diodes are also named as varicap diodes. The varactor diode or varicap diode is shown in circuit diagrams or schematics using a symbol that combines the diode and capacitor symbols. It is found that the thickness of the depletion region in the varactor diode is proportional to the square root of the reverse voltage across it.

The low resistance of these varactors makes them appropriate for high q resonators in wireless system vcos to frequencies over 10 ghz. The varactor diode is a device that is processed so to capitalise on the properties of the depletion layer of a p n diode. Varactor diode is one kind of semiconductor microwave solid state device and the applications of this diode mainly involve in where variable capacitance is preferred which can be accomplished by controlling voltage.

Please view our large selection of varactor diodes below. An ideal diode will have zero resistance in one direction and infinite resistance in the reverse direction. The smv123x series of silicon hyperabrupt junction varactor diodes are designed for use in voltage controlled oscillators vcos with a low tuning voltage operation.

A diode is defined as a two terminal electronic component that only conducts current in one direction so long as it is operated within a specified voltage level. The smv123x series of silicon hyperabrupt junction varactor diodes are designed for use in voltage controlled oscillators vcos with a low tuning voltage operation. Mouser is an authorized distributor for many varactor diode manufacturers including diodes inc infineon nxp on semiconductor skyworks toshiba more.

Microsemis prodiuct line inlcudes also step recovery diodes harmonic generator varactors impatt diodes and multiplier diodes. Microsemi offers a wide variety of abrupt and hyperabrupt si and gaas varactor diodes in a variety of surface mount ceramic or glass packages as well as in die form. Varactor diodes are available at mouser electronics from industry leading manufacturers.

In this way it is obvious that it is being used as a variable capacitor rather than a rectifier. Under reverse bias the carriers in each region holes in the p type and electrons in the n type move away from the junction leaving an area that is depleted of carriers. The actual capacitance range for a varactor diode depends upon a number of factors.

The width of the depletion region for a given voltage etc.
