I-varactor diode iyi-diode ekhethekile eklanywe ngokukhethekile ngokuvumelana nesimiso sokuthi amandla okuhlangana "we-PN junction" ngaphakathi kwe-diode evamile angashintsha ngokushintsha kwamandla okuguqula asetshenzisiwe.

I-varactor diode isetshenziswa kakhulu kusekethe yokushintshashintsha kwemvamisa ephezulu yocingo oluphathwayo noma ucingo lwasendlini ocingweni olungenazintambo ukuze kubonwe ukuguqulwa kwesiginali yefrikhwensi ephansi kusiginali yefrikhwensi ephezulu futhi iyikhiphe. Esimeni sokusebenza, i-varactor diode modulation voltage ngokuvamile yengezwa ku-electrode engalungile Yenza amandla angaphakathi e-varactor diode ashintshe nge-modulation voltage.

I-varactor diode iyahluleka, ikakhulukazi ibonakaliswa njengokuvuza noma ukusebenza kabi:

(1) Uma ukuvuza kwenzeka, isekethe yokushintshashintsha kwemvamisa ephezulu ngeke isebenze noma ukusebenza kokumodulisa kuzokonakala.

(2) Uma ukusebenza kwe-varactor konakala, ukusebenza kwesekethe ye-modulation ye-high-frequency modulation akuzinzile, futhi isignali ye-high-frequency eshintshiwe ithunyelwa kwelinye iqembu futhi yamukelwe ukuhlanekezela elinye iqembu.

Uma kwenzeka esinye sezimo ezingenhla, i-varactor diode yemodeli efanayo kufanele ishintshwe.
