Uhlalutyo lwamandla kunye nokulinganisa

Ukusetyenziswa kwezandisi zengxolo ephantsi (LNAs) kuhlalutyo lwamandla kunye nokulinganisa ikakhulu kubandakanya le miba ilandelayo:

1. Kwiinkqubo zonxibelelwano ezingenazintambo, i-LNA inokunyusa amandla omqondiso, ngaloo ndlela iphucula umgama wokuhambisa kunye nesantya sokuhambisa inkqubo. Ukongeza, inokunciphisa inqanaba lengxolo yesiginali, iphucule umlinganiso we-signal-to-noise, kwaye iphucule ngakumbi ukusebenza kwenkqubo.

2. Kwizixhobo zovavanyo lwe-elektroniki, ii-LNAs zidla ngokusetyenziselwa ukukhulisa iimpawu ezibuthathaka ukwenzela ukulinganisa ngokuchanekileyo iiparamitha ezinje ngamaza, i-amplitude kunye nesigaba.

3. Kwezinye iimvavanyo zenzululwazi kunye nemilinganiselo yobunjineli, i-LNA isebenza njenge-signer gainer, ikhulisa umqondiso kunye nokuphucula umlinganiselo wesignali ukuya kwingxolo ukwenzela ukuba umqondiso ubonwe, uhlalutye kwaye urekhodwe ngokuchanekileyo ngakumbi.

4. Kwiisistim zonxibelelwano ngesathelayithi, ii-LNAs zisetyenziselwa ukukhulisa imiqondiso ebuthathaka efunyenwe ngeesathelayithi.
