Qhov no suav nrog kev ntsuam xyuas ntawm lawv cov peev xwm tsim khoom, kev tswj hwm kev tswj hwm zoo, kev tswj hwm ib puag ncig, thiab kev tawm tswv yim kev lag luam.

Thaum ib lub chaw tsim khoom dhau los ntawm peb qhov kev tshuaj xyuas, peb ua qhov ntsuas qhov tob ntawm lawv cov khoom, suav nrog kev ntsuas hluav taws xob, kev ntsuas kev sib raug zoo ib puag ncig, thiab kev ntsuas lub neej ntev. Qhov kev ua kom zoo thiab kev ua haujlwm zoo no tso cai rau peb kom peb cov neeg siv khoom paub tseeb tias txhua yam khoom siv los ntawm Minintel tau raug xaiv ua tib zoo xaiv, kom ntseeg tau tias muaj kev thaj yeeb nyab xeeb txog qhov zoo. Qhov no tso cai rau peb cov neeg siv khoom tsom mus rau tag nrho lub siab ntawm cov khoom tsim kho tshiab thiab kev txhim kho kev lag luam yam tsis muaj kev txhawj xeeb txog cov khoom siv.

Tsis tas li ntawd, peb muab cov tswv yim sib tw nqi sib tw, tshwj xeeb tshaj yog muaj txiaj ntsig zoo rau cov neeg yuav khoom ntau, nrog rau cov nqi zoo dua los pab peb cov neeg siv khoom txo nqi thiab txhim kho lawv cov kev sib tw ua lag luam. Txawm hais tias koj yog tus pib lag luam lossis cov chaw tsim khoom loj, Minintel yog koj tus khub muaj kev vam meej. Peb mob siab rau muab koj nrog ib-nres kev daws teeb meem rau cov khoom siv hluav taws xob, ua kom koj tswj tau txoj haujlwm tseem ceeb hauv kev hloov pauv kev lag luam sai.

Tiv tauj peb

Hloov pauv Capacitance Diode yog cov khoom siv tshwj xeeb semiconductor uas siv qhov kev hloov pauv hloov pauv cov yam ntxwv ntawm PN kev sib tshuam, yog li ua tiav qhov tunability ntawm lub peev xwm.

Txhais thiab yam ntxwv

Txhais:Ib tug varactor diode yog ib tug semiconductor diode uas kho nws cov hlws ris capacitance los ntawm kev hloov lub reverse bias voltage. Nws yog sib npaug rau qhov sib txawv capacitor, thiab PN hlws ris capacitance ntawm nws ob lub electrodes txo nrog qhov nce ntawm qhov rov qab voltage.

Yam ntxwv:Kev sib raug zoo ntawm qhov rov qab tsis zoo voltage thiab junction capacitance ntawm varactor diode yog nonlinear. Thaum qhov rov qab voltage nce, lub depletion txheej widens, uas ua rau ib tug txo nyob rau hauv capacitance; Piv txwv li, thaum qhov rov qab voltage txo, lub depletion txheej yuav nqaim thiab lub capacitance nce.

daim ntawv thov cheeb tsam

Tsis siv neeg zaus tswj (AFC):Varactors tau dav siv nyob rau hauv tsis siv neeg zaus tswj circuits los hloov qhov zaus ntawm oscillators los ntawm kev kho lawv cov capacitance, yog li tswj kev sib xws nrog zaus ntawm cov teeb liab tau txais.

Scanning oscillation:Nyob rau hauv lub scanning oscillation Circuit Court, lub varactor diode tuaj yeem tsim lub teeb liab nrog lub zaus sib txawv ntawm lub sijhawm, uas yog siv rau kev ua haujlwm hauv radar, ultrasound, thiab lwm yam khoom siv.

Zaus modulation thiab tuning:Varactor diodes kuj tau siv nyob rau hauv zaus modulation circuits thiab tuning circuits. Piv txwv li, lub tshuab hluav taws xob hluav taws xob ntawm lub teeb xim TV hloov qhov kev sib tshuam ntawm lub varactor diode los ntawm kev tswj cov DC voltage los xaiv lub resonant zaus ntawm ntau txoj kev.

Ntim daim ntawv

Varactors muaj nyob rau hauv ntau hom ntim khoom kom haum rau ntau hom kev thov

iav sealing: me me thiab nruab nrab-lub zog varactor diodes feem ntau ntim rau hauv cov iav ntim, uas muab kev sib khi zoo thiab ruaj khov.

Plastic encapsulation: Qee qhov varactor diodes kuj tau ntim hauv cov yas kom txo tau tus nqi thiab qhov hnyav.

Kub sealing: Rau varactor diodes nrog lub zog siab, hlau casing feem ntau yog siv rau ntim los txhim kho cov cua sov dissipation thiab kev ntseeg tau.
