Here, a back-to-back varactor configuration minimizes the effects of RF modulation. If a varying signal is injected, the bias across one diode increases as the other decreases, keeping overall ...

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 than the intrinsic stuff to make ...

This revealed that the V47 diodes were not the dual Vishay diode, but rather the American MicroSemiconductor varactor diode. The varactor-input amplifier was invented by Bob Pease’s boss George ...

Third, the coil L must be wound by hand and adjusted by stretching. It all ads with a weak signal that tends to drift in frequency. In contrastm the transmitter schematic we present here eliminates ...

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 ...

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

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).

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.
