0.01-1Ghz siab nce Tsis tshua muaj suab nrov Power Amplifier
| Leader-mw | Taw qhia rau kev nce siab qis qis qis zog Amplifier |
Lub suab nrov nrov nrov nrov nrov (LNA) ua haujlwm nyob rau hauv 0.01 txog 1GHz zaus ntau yog ib qho tseem ceeb hauv kev sib txuas lus niaj hnub thiab kev siv teeb liab. Cov cuab yeej no yog tsim los txhim kho cov teeb liab tsis muaj zog thaum qhia cov suab nrov tsawg tsawg, ua kom pom cov teeb liab zoo rau kev ua haujlwm ntxiv lossis kev tshuaj xyuas.
LNA feem ntau nta cov khoom siv semiconductor thiab cov txheej txheem tsim hluav taws xob kom ua tiav nws cov yam ntxwv tshwj xeeb. Nws qhov nce, uas tuaj yeem ua tau ntau yam, tso cai rau nws ua kom muaj txiaj ntsig zoo tsis muaj qhov cuam tshuam loj, ua rau nws zoo tagnrho rau siv nyob rau hauv ib puag ncig uas lub teeb liab lub zog yog qhov txwv, xws li hauv kev sib txuas lus satellite lossis kev sib txuas mus ntev wireless.
Kev khiav hauj lwm dhau ntawm 0.01 mus rau 1GHz zaus band npog dav dav ntawm cov ntawv thov suav nrog VHF / UHF xov tooj cua, microwave txuas, thiab qee lub tshuab radar. Lub amplifier qhov dav bandwidth ua kom muaj kev sib raug zoo nrog ntau yam qauv kev sib txuas lus thiab cov txheej txheem, txhim kho nws txoj kev siv ntau yam thoob plaws ntau lub platform thiab siv rooj plaub.
Ntxiv nrog rau qhov nce siab thiab tsis tshua muaj suab nrov, lwm cov ntsiab lus tseem ceeb rau cov amplifiers muaj xws li cov tswv yim thiab cov zis impedance txuam, linearity, thiab stability ntawm qhov kub thiab txias. Cov cwj pwm no koom ua ke rau lawv txoj kev ntseeg siab thiab kev ua tau zoo hauv kev tuav cov teeb liab kev ncaj ncees nyob rau hauv ntau yam xwm txheej.
Zuag qhia tag nrho, lub suab nrov nrov nrov hauv 0.01-1GHz ntau zaus yog qhov tseem ceeb rau kev txhim kho qhov rhiab heev thiab kev ua tau zoo ntawm kev sib txuas lus thiab kev kuaj xyuas tshuab, ua kom pom tseeb thiab txhim khu kev qha teeb liab txais thiab xa mus.
