Lub suab nrov qis (LNA) yog lub suab nrov uas muaj suab nrov tsawg. Nws yog tsuas yog siv los ua kom lub zog tsis muaj zog thaum txo cov suab nrov cuam tshuam los txhim kho lub teeb liab-rau- suab nrov piv. Nws feem ntau yog muab tso rau hauv pem hauv ntej kawg ntawm lub xov tooj cua txais xov tooj cua, xws li tom qab lub kav hlau txais xov, kom nthuav dav cov cim tsis muaj zog tau txais los ntawm huab cua.
Yam ntxwv:
1.Low Noise Figure: Cov yam ntxwv tseem ceeb ntawm lub suab nrov tsis tshua muaj suab nrov yog nws cov suab nrov tsis tshua muaj suab nrov (Noise Figure, NF). Qhov qis dua lub suab nrov, lub suab nrov tsawg cuam tshuam lub amplifier qhia, ua rau lub teeb liab-rau-suab nrov dua piv.
2.High Gain: Txhawm rau kom muaj txiaj ntsig zoo ntawm cov teeb liab tsis muaj zog, lub suab nrov qis qis feem ntau muaj qhov nce siab, uas tuaj yeem ua rau muaj qhov loj ntawm lub teeb liab.
3.Wide Bandwidth: Ntau lub suab nrov qis yog tsim los ua kom dav dav, muaj peev xwm tuav cov teeb liab hla ntau zaus.
4.Kev ruaj ntseg zoo: Lub suab nrov qis yuav tsum muaj kev ruaj ntseg zoo kom tsis txhob oscillation thaum ua haujlwm ntawm cov khoom siv siab.
Tsawg suab nrov Amplifiers tau dav siv hauv kev sib txuas lus wireless, kev sib txuas lus satellite, radar, hluav taws xob tiv thaiv, xov tooj cua astronomy, thiab lwm yam.
Qualwave muab ntau yam suab nrov nrov amplifiers los ntawm 4K txog 260GHz, thiab lub suab nrov tuaj yeem qis li 0.7dB.
Peb qhia ib qho ntawm lawv, nrog ntau zaus ntawm 9KHz txog 3GHz, nce ntawm 43dB, lub suab nrov ntawm 3dB, P1dB ntawm 16dBm.
