Ukuqonda inductor engundoqo yomoyas

inductor engundoqo yomoyas zenzelwe ngokukodwa UKUNGAKUSEBENZISA i-ferromagnetic core, kwaye zahluke kancinane kwintsimbi okanye abazalwana babo be-ferrite-core. Uyilo olunjalo aluzenzekelanga, kodwa lukhetho lwangabom lokwandisa ukusebenza kwabo kwi-RF applications. Olona ncedo luphambili lokungasebenzisi undoqo wemagnethi kukuncitshiswa kwelahleko engundoqo ebandakanyekayo ekutshintshiseni umhlaba wemagnethi kwiintsimbi, ngakumbi kwiifrikhwensi eziphezulu. I-Hysteresis kunye nokulahleka kwangoku kwe-eddy (ilahleko eziphambili) kunokunciphisa ukusebenza kakuhle kwe-inductor ngokusebenzisa amandla njengobushushu. Ke ngomoya (okanye nayiphi na i-non-magnetic) njengondoqo, inductor engundoqo yomoyas zinciphisa ilahleko yamandla kwaye zigqwesile kwezo zicelo zifuna ukusebenza kakuhle.

Ngaphezu koko, inductor engundoqo yomoyas zaziwa ngokubonisa ukugcinwa kwe-Q factor ephezulu, echaza into ebonisa ukusebenza kakuhle kwe-inductor kunye nokuxinana kwencopho ye-resonant. Oku kubaluleke kakhulu kwizicelo ezifana nee-transmitter zikanomathotholo, ii-oscillator ze-high-frequency-oscillators kunye nabakhethi bamafrikhwensi-apho imfezeko yomqondiso kunye nokukhetha kubaluleke kakhulu. Ukunqongophala kwe-ferromagnetic core kukwathetha ukuba inductor engundoqo yomoyas azina-non-linearity okanye saturation auto-izixhobo phantse ngokungaguquguqukiyo zikhapha imathiriyeli kunye nemagnethi ephezulu permeability, ukuze umsebenzi we-inductor uphantse ube ngumgca kuluhlu olubanzi kakhulu lweemeko zokusebenza. Olu lungelelwano lubalulekile ekuthembekeni komqondiso, ngakumbi kwiisekethe zeRF apho ukugqwethwa nokuba kuncinci kobukhulu kunokuthoba kakhulu ukusebenza.

inductor engundoqo yomoyas nabo banesicelo kwi-high frequency circuitry apho ixabiso elifunekayo le-inductance liphantsi kodwa umgangatho wesignali ubaluleke kakhulu. Umthamo wabo weparasitic ophantsi unceda ukufezekiswa kwezandi zezandi eziphezulu-- ngakumbi ziluncedo kwii-transmitters ze-modulation (FM) okanye iisekethe zedijithali ezinesantya esiphezulu umzekelo. Nangona i-inductance yabo ihlala isezantsi kune-inductors ene-magnetic cores, indibaniselwano yokusebenza kakuhle, ilahleko ephantsi, kunye neendawo zokusebenza eziphezulu. inductor engundoqo yomoyaphakathi kwamacandelo ayimfuneko kuluhlu olubanzi lweenkqubo zombane zanamhlanje.

Ukubaluleka koMsebenzi oNgcono

Ukubaluleka kokuqonda ukusebenza okuphezulu inductor engundoqo yomoyaI-s ayikokubaxwa nangayiphi na indlela kwaye yandiswa kumjikelezo weRF wanamhlanje, apho ukusebenza kakuhle kunye nokuthembeka kuyinkxalabo ephezulu. Ukusebenza okuphezulu kwiRF rhoqo kufuna amacandelo e-RF anokumelana neefrikhwensi eziphezulu kunye neemeko zentsimi.
