Tus varactor diode yog qhov tshwj xeeb diode tsim tshwj xeeb raws li lub hauv paus ntsiab lus tias kev sib tshuam ntawm sab hauv" PN hlws ris" ntawm qhov zoo tib yam diode tuaj yeem hloov pauv nrog qhov hloov pauv ntawm qhov thov hloov hluav taws xob.
Varactor diodes siv rau hauv qhov kev hloov siab ntau ntawm xov tooj ntawm lub xov tooj ntawm tes lossis thaj av hauv lub xov tooj tsis muaj xov tooj kom ua tiav kev hloov kho ntawm cov kev sib txuas mus rau cov cim hluav taws xob tsawg tsawg thiab xa tawm.
Hauv lub xeev ua haujlwm, kev hloov kho voltage ntawm varactor diode feem ntau ntxiv rau qhov tsis zoo electrode, yog li cov khoom sib txuas sab hauv ntawm lub varactor diode hloov nrog qhov hloov ntawm cov hloov hluav taws xob.
