Lub suab nrov tsis tshua muaj suab nrov feem ntau yog siv los ua lub suab nrov lossis nruab nrab zaus preamplifier rau ntau hom xov tooj cua receivers, nrog rau amplifying circuits rau high-rhiab heev hluav taws xob nrhiav khoom siv. Thaum amplifying tsis muaj zog teeb liab, lub suab nrov tsim los ntawm lub amplifier yuav cuam tshuam nrog lub teeb liab. Yog li ntawd, nws cia siab tias yuav txo cov suab nrov no txhawm rau txhim kho lub teeb liab-rau-suab nrov piv ntawm cov zis. Lub degradation ntawm lub teeb liab-rau-suab piv piv los ntawm lub amplifier feem ntau yog qhia los ntawm lub suab nrov F.
Tsawg suab nrov amplifiersyog ib qho tseem ceeb ntawm cov receiver circuit, uas ua thiab hloov cov teeb liab tau txais mus rau hauv cov ntaub ntawv. LNAs yog txhais tau tias yuav tsum nyob ze rau cov cuab yeej tau txais txhawm rau txo qis kev cuam tshuam. Lawv pab tsuas yog ib qho me me ntawm cov suab nrov (cov ntaub ntawv tsis muaj txiaj ntsig) rau cov teeb liab tau txais vim tias ib qho ntxiv yuav ua rau lub teeb liab uas twb tsis muaj zog lawm. Ib qho LNA ua haujlwm thaum lub teeb liab-rau-lub suab sib piv (SNR) siab thiab yuav tsum tau txo qis li 50% thaum lub zog nce. Thawj feem ntawm lub receiver los cuam tshuam lub teeb liab yog LNA, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem kev sib txuas lus.
Kev siv ntawm lub suab nrov nrov amplifier
LNA tau ntsib kev txhim kho thaum ntxov ntawm cov kua helium-txias parametric amplifiers thiab chav kub parametric amplifiers. Nrog rau txoj kev loj hlob sai ntawm cov cuab yeej technology, nws tau raug hloov los ntawm microwave field-effect transistor amplifiers nyob rau hauv xyoo tas los. Hom amplifier no muaj cov yam ntxwv zoo ntawm qhov me me, tus nqi qis, thiab lub teeb yuag. Tshwj xeeb tshaj yog nyob rau hauv cov ntsiab lus ntawm cov yam ntxwv ntawm lub xov tooj cua zaus, nws muaj cov yam ntxwv ntawm lub suab nrov tsawg, dav zaus band, thiab siab nce. Nws tau dav siv nyob rau hauv C, Ku, Kv, thiab lwm yam zaus bands. Thiab lub suab nrov ntawm cov suab nrov nrov nrov nrov amplifiers tuaj yeem qis dua 45K.
CovTsawg suab nrov amplifier (LNA)Feem ntau yog tsim los rau kev sib txuas lus hauv kev sib txuas lus hauv chaw nres tsheb, xws li transceiver wireless kev sib txuas lus phaib, ntauwd-mounted amplifiers (TMA), combiners, repeaters, thiab tej thaj chaw deb/digital wireless broadband head-end khoom. Lub suab nrov qis (NF, Noise Figure) tau teeb tsa tus qauv tshiab. Tam sim no, kev lag luam kev sib txuas lus wireless tau ntsib qhov kev sib tw ntawm kev muab cov teeb liab zoo tshaj plaws thiab kev pab cuam hauv cov neeg coob coob. Cov neeg txais rhiab heev yog ib qho tseem ceeb tshaj plaws uas yuav tsum tau ua nyob rau hauv kev tsim ntawm lub hauv paus chaw nres tsheb txais txoj kev. Kev xaiv LNA tsim nyog, tshwj xeeb tshaj yog thawj Qib LNA tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov chaw nres tsheb hauv paus, thiab cov suab nrov qis kuj yog lub hom phiaj tseem ceeb tsim.
