Varactor diode
Varactor diodes, tseem hu ua "variable reactance diodes", yog ua los ntawm cov yam ntxwv uas lub hlws ris capacitance hloov nrog cov ntaub ntawv voltage thaum PN junction yog rov qab biased. Thaum qhov hluav taws xob thim rov qab nce ntxiv, qhov sib txuas capacitance txo qis, thiab rov ua dua. Lub capacitance ntawm varactor diode feem ntau yog me me. Tus nqi siab tshaj plaws yog kaum rau pua pua PI, thiab qhov sib piv ntawm qhov siab tshaj plaws capacitance rau qhov tsawg kawg nkaus capacitance yog li 5: 1. Nws yog tsuas yog siv raws li nws pib tuning, zaus hloov kho thiab sib npaug ntawm qhov sib npaug ntawm qhov hluav taws xob ntau zaus, piv txwv li, raws li qhov sib txawv ntawm qhov sib txawv hauv kev sib txuas ntawm TV receiver.
Cov yam ntxwv tseem ceeb yog: xoom bias hlws ris capacitance, xoom bias voltage qhov zoo tshaj tus nqi, rov qab tawg voltage, nruab nrab rov qab bias, nominal capacitance, capacitance variation ntau yam (raws li daim tawv nqaij txoj kev) thiab txiav tawm zaus.
