Vim li cas siv lub inductor?

Ntau cov neeg siv khoom sib txuas lus nrog ib leeg los ntawm kev sib txuas lus broadband, thiab bandwidth ntawm cov ntaub ntawv kev sib txuas lus yog nce. Kev ncaj ncees ntawm RF signals tau dhau los ua kev txhawj xeeb loj hauv kev tsim. Kab lus no muab qee qhov piv txwv ntawm kev siv cov inductors sib txawv rau kev sib cais ntawm RF nyob rau hauv ib lub voj voog rau cov ntaub ntawv faib los ntawm cov ntawv nqaim nqaim (xws li cov khoom siv nqa tau) mus rau broadband tes hauj lwm. Ntau hom inductors siv hauv cov ntawv thov no tau txheeb xyuas thiab sib tham.

Qhov tseem ceeb, ib qho inductor yog lub lim dej qis. Ntawm qhov siab zaus, inductors dhau los ua qhov siab impedance uas tuaj yeem siv rau kev sib cais RF. High frequencies tsis tuaj yeem dhau los ntawm inductors, tab sis tso cai rau tam sim no ncaj qha thiab tsawg zaus cov cim hla dhau. Yog tsis muaj hom kev rho tawm no, kav hlau txais xov efficiency yuav txo qis, teeb liab poob yuav tshwm sim, thiab RF suab yuav cuam tshuam rau lwm qhov hauv Circuit Court.

Lub ncov impedance ntawm lub inductor tshwm sim ntawm tus kheej resonant zaus. Qhov loj ntawm lub ncov inductance muaj feem xyuam rau qhov zoo tshaj plaws (Q factor) ntawm inductance. Tsawg poob inductors nrog siab Q qhov tseem ceeb muaj qhov siab siab siab impedance, thaum poob inductors muaj qis dua peak impedance.

Los ntawm kev hloov txoj kev winding ntawm lub kauj lossis cov ntaub ntawv siv hauv cov qauv, ntau qhov resonances tuaj yeem hloov kho kom pom qhov siab impedance tshaj qhov dav bandwidth.
