Varactor (varicap) circuit symbol. How does a varactor diode work? To form the PN junction that makes a diode, half the piece is doped with a trace amount of “donor atoms” that have one more electron ...

LC-tank circuit portion. Varactor (or “varicap”) diodes are used primarily in radio-frequency (RF) circuits to provide a capacitance that can be varied by changing the applied voltage.

Global Varactor Diode Market Analysis & Trends During the Forecast Period, 2019-2027 - ResearchAndMarkets.com December 18, 2019 05:13 AM Eastern Standard Time.

LONDON--(BUSINESS WIRE)--Technavio has been monitoring the varactor diode market and it is poised to grow by USD 334.91 million during 2019-2023, progressing at a CAGR of almost 11% during the ...

For designs where tuner-diode matching is critical and space is limited, the ZMDC831BTA and 832BTA dual common-cathode, hyperabrupt varactor diodes report high tolerance C-V characteristics ...

It can be used as a simple cordless microphone. The circuit uses two integrated circuits from Maxim. IC1 a MAX4467, is an amplifier raising the microphone signal to a level suitable for frequency ...

When applied to these devices, the varactor attained a charge sensitivity of 4.8 μe Hz −1/2 and a remarkable capacitance sensitivity of 0.04 aF Hz −1/2.

There is no traditional main tuning capacitor. Instead a 1SV149 varactor provides the radio’s main tuning capacity (the diode tunes between 35 to 500 pF).
