High zaus Circuit Courtyog ib hom tshwj xeeb ntawm Circuit Court feem ntau siv hauv cov khoom siv hluav taws xob uas muaj zaus ntau dua li ob peb megahertz. Piv nrog rau cov khoom siv hluav taws xob tsawg, cov hluav taws xob ntau zaus yuav tsum muaj qhov tseeb dua thiab cov ntsuas kev ua tau zoo dua. Lub hauv paus ntsiab lus ntawm high-frequency circuits yog siv cov kev hloov hauv high-frequency electromagnetic teb los xa cov teeb liab. Nws feem ntau suav nrog cov khoom siv ceev ceev xws li amplifiers, lim, mixers, thiab antennas.
Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm high-frequency circuits suav nrog ntau lub cev muaj zog, xws li kev nthuav tawm, kev xav, thiab attenuation. Raws li cov xwm txheej no, peb tuaj yeem tsim cov kab hluav taws xob ntau zaus siv txoj hauv kev xws li cov kab sib kis, cov kab hluav taws xob resonant, thiab cov resonators. Cov kab hluav taws xob ntau zaus kuj yuav tsum muaj peev xwm teb tau sai thiab ruaj khov kom ntseeg tau tias lawv xa cov teeb liab raug ntawm ib lub voj voog mus rau lwm qhov.
Piv rau cov hluav taws xob tsawg zaus, cov hluav taws xob ntau zaus muaj ntau yam kev siv. Niaj hnub no, high-frequency circuits yog dav siv nyob rau hauv teb xws li kev sib txuas lus wireless, radar qhia, thiab terahertz optics. Hauv thaj chaw ntawm kev sib txuas lus wireless, qhov tseem ceeb ntawm high-frequency circuits yog qhov tseeb ntawm nws tus kheej. Xov tooj cua signals yog kis los ntawm electromagnetic nthwv dej nyob rau hauv cov huab cua, thiab zaus ntawm electromagnetic tsis yog nyob nruab nrab ntawm ob peb megahertz thiab ob peb gigahertz. High zaus circuits tuaj yeem ua tiav cov teeb liab hloov, demodulation, amplification thiab lwm yam haujlwm hauv qhov ntau zaus, yog li lawv tau siv dav hauv cov khoom siv sib txuas lus.
