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 ...

Designed to control the frequency of crystal oscillator circuits, the 3022 series of high-ratio, hyperabrupt varactor tuning diodes is designed to deliver a dc bias control voltage from -0.3V to -4V.

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 ...

Toshiba Corporation (TOKYO: 6502) today announced the development of a compact MOS-Varactor 1 simulation model that delivers high level accuracy from DC to the millimeter wave (60 GHz) region. The ...
