Variable Capacitance Diode chinhu chakakosha semiconductor chinoshandisa reverse bias kushandura capacitance maitiro ePN junction, nokudaro kuwana tunability ye capacitance.
Tsanangudzo uye maitiro
Tsanangudzo:A varactor diode is semiconductor diode inogadzirisa iyo junction capacitance nekushandura reverse bias voltage. Iyo yakaenzana neiyo variable capacitor, uye iyo PN junction capacitance pakati pema electrode ayo maviri inoderera nekuwedzera kweiyo reverse voltage.
Hunhu:Hukama huri pakati pe reverse bias voltage uye junction capacitance ye varactor diode haina mutsara. Kana iyo reverse voltage ichiwedzera, depletion layer inowedzera, zvichiita kuti kuderera kwe capacitance; Sezvineiwo, kana reverse voltage yadzikira, depletion layer inova diki uye capacitance inowedzera.
nzvimbo yekushandisa
Automatic frequency control (AFC):Varactors inoshandiswa zvakanyanya mu otomatiki frequency control circuits kushandura frequency ye oscillator nekugadzirisa capacitance yavo, nekudaro kuchengetedza kuenderana neiyo frequency yechiratidzo chakagamuchirwa.
Kuongorora oscillation:Mune scanning oscillation circuit, iyo varactor diode inogona kuburitsa chiratidzo chine frequency inosiyana nekufamba kwenguva, iyo inoshandiswa pakuongorora mabasa mu radar, ultrasound, uye zvimwe zvishandiso.
Frequency modulation uye tuning:Varactor diodes anoshandiswawo mu frequency modulation circuits uye tuning circuits. Semuyenzaniso, iyo yemagetsi tuner yeruvara TV seti inoshandura iyo junction capacitance yevaractor diode nekudzora iyo DC voltage kusarudza iyo resonant frequency yematanho akasiyana.
Packaging fomu
Varactors anowanikwa mune akasiyana siyana ekurongedza masitaera kuti aenderane kune akasiyana maapplication zvinodiwa
Kuisa chisimbiso chegirazi: Diode diki nepakati-simba varactor diode inowanzoiswa mumagirazi akavharirwa, ayo anopa chisimbiso chakanaka uye kugadzikana.
Plastic encapsulation: Mamwe ma varactor diode akaiswawo mupurasitiki kuderedza mutengo uye uremu.
Kuisa chisimbiso chegoridhe: Kune varactor diodes ine simba rakanyanya, simbi casing inowanzoshandiswa kurongedza kugadzirisa kupisa kupisa uye kuvimbika.
