Iyo varactor diode idhidhiyo yakakosha yakanyatso gadzirwa zvinoenderana nemusimboti wekuti junction capacitance ye "PN junction" mukati meiyo yakajairwa diode inogona kushanduka nekuchinja kweiyo inoshandiswa reverse voltage.
Iyo varactor diode inonyanya kushandiswa muyepamusoro-frequency modulation dunhu renhare mbozha kana landline mufoni isina tambo kuona kugadziridzwa kweiyo yakaderera-frequency chiratidzo kune yakakwira-frequency chiratidzo uye kuiburitsa. Mumamiriro ekushanda, iyo varactor diode modulation voltage inowanzowedzerwa kune yakaipa electrode Ita iyo yemukati capacitance yevaractor diode shanduko nemodulation voltage.
Iyo varactor diode inotadza, inonyanya kuratidzwa sekudonha kana kusaita zvakanaka:
(1) Kana kuvuza kuchiitika, iyo yakakwira-frequency modulation wedunhu haishande kana kuita kwemodulation kunokanganisa.
(2) Apo kushanda kwevaractor kwakaderera, kushanda kwepamusoro-frequency modulation circuit haina kugadzikana, uye iyo modulated high-frequency signal inotumirwa kune imwe bato uye yakagamuchirwa kukanganiswa neimwe bato.
Kana imwe yemamiriro ezvinhu ari pamusoro ichiitika, varactor diode yemhando imwechete inofanira kutsiviwa.
