RF tutorials - The Varicap or Varactor Diode

#109 In this video I look at one of the basic components used in modern RF circuitry - the varicap (sometimes called the varactor) diode. This component is widely used in tuning circuits to replace mechanical variable capacitors but it also has applications in frequency multiplication. I look at how the component works and then try to perform some experiments with it. Datasheets: https://www.onsemi.com/pub/Collateral... https://www.infineon.com/dgdl/Infineo...
