Amplifier ea lerata e tlase (LNA), frequency 9K~1GHz, fumana 30dB, palo ea lerata (NF) 2dB

Amplifier ea lerata e tlase ke karolo ea bohlokoa lits'ebetsong tsa RF/microwave, tse sebelisoang haholo ho holisa mats'oao a fokolang ha a ntse a fokotsa lerata le eketsehileng. Mesebetsi ea eona ea mantlha le maemo a ts'ebeliso ke tse latelang:

Mesebetsi ea mantlha:

1. Ho hōlisa pontšo
Ntlafatsa boholo ba matšoao a fokolang a amoheloang ke li-antenna kapa li-sensor ho netefatsa ts'ebetso e sebetsang ka lipotoloho tse latelang joalo ka li-mixers le ADC.
2. Khatello ea lerata
Ka ho ntlafatsa moralo le ho sebelisa lisebelisoa tse nang le lerata le tlase, setšoantšo sa "self-intl" sa lerata (NF) se laoloa ka har'a mefuta ea 0.5-3dB (amplifier e loketseng NF = 0dB).

Maemo a Kopo:

1. Sistimi ea radar
Radara ea sesole (joalo ka radar ea taolo ea mollo o tsamaisoang ke moea) le radar ea baahi (joalo ka koloi millimeter wave radar), LNA e sebelisoa ho holisa lets'oao le fokolang la molumo (karolelano ea lerata la SNR <0dB) e bonts'itsoeng ke sepheo. Ha o feta sehokelong sa amplification le NF <2dB, radar e ka lemoha liphofu tse nang le RCS e hole kapa e tlase (radar cross section).
2. Mokhoa oa puisano o se nang mohala
Amplifier ea lerata e tlase ke karolo ea mantlha ea liteishene tsa 5G/6G, likhokahano tsa sathelaete, le lihokelo tse amohelang mohala. E ikarabella bakeng sa ho holisa lerata le tlase (NF <1.5dB) ea mats'oao a fokolang a RF (a tlase joalo ka -120dBm) a hapiloeng ke lenakana pele ho lets'oao la lets'oao, ho ntlafatsa haholo ho amoheloa ha sistimi. Mohlala, sehlopheng sa maqhubu a millimeter wave frequency (24 - 100GHz), LNA e ka lefella ho fihla ho 20dB ea tahlehelo ea tsela, ho netefatsa botsitso ba phetiso ea data e potlakileng.
3. Sesebelisoa se phahameng sa ho hlahloba ka ho nepahala
Lisebelisuoa tse kang spectrum analyzers le vector network analyzers (VNA), LNA e khetholla ka ho toba ts'ebetso ea lerata la sesebelisoa le mefuta e fapaneng ea matla. LNA e ka ntlafatsa kutlo ea sesebelisoa ka ho holisa lets'oao le lekantsoeng la boemo ba nV ho mofuta o sebetsang oa quantization oa ADC (joalo ka 1Vpp). Ho sa le joalo, ultra-low noise coefficient (NF <3dB) e ka fokotsa ho se tsitse ha tekanyo le ho fokotsa liphoso tsa tekanyo.
4. Eketsa libaka tsa kopo
Bolepi ba linaleli ba seea-le-moea: Thelesekoupo ea FAST e itšetlehile ka mokelikeli oa helium o pholileng LNA (NF ≈ 0.1dB) ho nka mela e 21cm e bonahalang bokahohleng.
Khomphutha ea quantum: Ho holisa mats'oao a boemo ba μV (4 - 8GHz) a li-qubits tsa superconducting ho hloka ts'ebetso ea lerata le haufi le moeli oa quantum.
Ho nahana ka bongaka: Thepa ea MRI e ntlafatsa boemo ba μV mats'oao a matla a khoheli a nyutlelie ka LNA eo e seng ea makenete, ka ntlafatso ea karolelano ea lerata ho feta 10dB.

Qualwave Inc. e fana ka li-amplifiers tsa lerata le tlase ho tloha ho 9kHz ho isa ho 260GHz, tse nang le molumo o tlase ho 0.8dB.
Mohlala oa QLA-9K-1000-30-20, o etselitsoeng ka ho khetheha lipatlisiso tsa saense le mekhoa ea puisano, o finyella tekanyo e ntle ea ts'ebetso ea phaello ea 30dB le palo ea lerata ea 2dB sehlopheng sa maqhubu a 9kHz ~ 1GHz.
