Urusaku ruciriritse rusanzwe rukoreshwa nk'umuvuduko mwinshi cyangwa intera-interineti hagati ya radiyo zitandukanye, kimwe no kongera imiyoboro y'ibikoresho bya elegitoroniki byerekana ibikoresho. Iyo wongeyeho ibimenyetso bidakomeye, urusaku rwatewe na amplifier rushobora kubangamira cyane ibimenyetso. Kubwibyo, twizeye kugabanya uru rusaku kugirango tunonosore ibimenyetso-by-urusaku rwibisohoka. Iyangirika ryikigereranyo cyerekana-urusaku rwatewe na amplifier ubusanzwe bigaragazwa n urusaku F.
Urusaku rukenibintu byingenzi bigize imashini yakira, itunganya kandi igahindura ibimenyetso byakiriwe mumakuru. LNAs igenewe kuba hafi yicyuma cyakira kugirango igabanye igihombo. Batanga gusa urusaku ruke (amakuru adafite akamaro) kubimenyetso byakiriwe kuva ikindi cyose kizatesha agaciro cyane ibimenyetso bimaze gucika intege. LNA ikoreshwa mugihe igipimo cyerekana-urusaku (SNR) kiri hejuru kandi kigomba kugabanuka hafi 50% mugihe ingufu ziyongereye. Igice cya mbere cyabakira kugirango bahagarike ikimenyetso ni LNA, ikagira ikintu gikomeye mubikorwa byitumanaho.
Porogaramu ya urusaku ruke-rwinshi
LNA yiboneye iterambere ryambere ryamazi ya helium-akonje yibikoresho byongera ubushyuhe bwicyumba. Hamwe niterambere ryihuse ryikoranabuhanga, ryasimbuwe na microwave field-effect transistor amplifiers mumyaka yashize. Ubu bwoko bwa amplifier bufite ibintu byiza biranga ubunini buto, igiciro gito, kandi cyoroshye. Cyane cyane kubijyanye na radiyo yumurongo wa radiyo, ifite ibiranga urusaku ruke, umurongo mugari, hamwe ninyungu nyinshi. Byakoreshejwe cyane muri C, Ku, Kv, nandi matsinda ya frequency. Kandi ubushyuhe bwurusaku rwibisanzwe bikoreshwa-byongera urusaku rushobora kuba munsi ya 45K.
Uwitekaurusaku ruke rwinshi (LNA)igenewe cyane cyane ibikorwa remezo byitumanaho rya terefone igendanwa, nka amakarita y'itumanaho ya transceiver itumanaho, amakarita yongerewe imbaraga (TMA), ikomatanya, ibisubiramo, hamwe nibikoresho bya kure / bigizwe na enterineti. Igishusho gito (NF, Urusaku) rushyizeho urwego rushya. Kugeza ubu, ibikorwa remezo byitumanaho bidafite umugozi bihura ningorabahizi zo gutanga ubuziranenge bwibimenyetso no gukwirakwiza mubice byinshi. Kwakira ibyiyumvo ni kimwe mubisabwa cyane mugushushanya sitasiyo yakira inzira. Guhitamo LNA ikwiye, cyane cyane Urwego rwa mbere LNA irashobora kunoza cyane imikorere yimikorere yabakiriye sitasiyo fatizo, kandi indangururamajwi ntoya nayo ni intego nyamukuru yo gushushanya.
