    Ama-Block Downconverter (ama-LNB)

    Ezinhlelweni zokuxhumana, ukuze kube lula ukudluliselwa kwesignali nokufeza ukusetshenziswa kabusha kwesiteshi, imvamisa yesignali edluliselwayo iphezulu kakhulu, ngakho-ke ukuguqulwa kwemvamisa yesignali kuyisici esibalulekile socwaningo lwesistimu yokuxhumana. Ngokwesimo sangaphambi nangemva kokuguqulwa kwemvamisa, ingahlukaniswa ngokuguqulwa kwezansi (ukunciphisa imvamisa) kanye nokuguqulwa kwezansi (ukwanda kwemvamisa).
    Kumamukeli, uma isignali yemvamisa ephakathi etholwe ngemuva kokuxuba iphansi kunesignali yokuqala, khona-ke le ndlela yokuxuba ibizwa ngokuthi ama-block downconverters (ama-LNB).
    Indlela yama-block downconverters ukuphindaphinda isignali etholiwe ngesignali ye-oscillator yendawo ekhiqizwa yi-oscillator yendawo, bese uthola isignali eguquliwe ngesihlungi esidlula phansi. Izimpawu ezimbili eziphindaphindiwe zingahlukaniswa zibe ukuxubana kwangempela kanye nokuxubana okuyinkimbinkimbi ngokumelwa kwangempela noma okuyinkimbinkimbi.
    Inhloso yama-block downconverters ukunciphisa imvamisa yenkampani yesignali noma ukususa ngqo imvamisa yenkampani yenethiwekhi ukuze kutholakale isignali ye-baseband. Ngenxa yesekethe yayo elula kanye nezindleko eziphansi, indlela yokuguqula i-down isetshenziswa kabanzi emishinini yabantu abavamile kanye nemishini yezempi enezidingo zokusebenza eziphansi.

    Isicelo:

    1. I-Satellite TV: Ama-LNB ayizingxenye ezibalulekile ezinhlelweni zokwamukela i-satellite TV. Afakwa endaweni egxile ku-antenna yesathelayithi (i-paraboloid noma i-dish), athola isignali ye-TV edluliselwa yi-satellite, bese eyiguqula ibe isignali yemvamisa ephakathi engacutshungulwa yi-receiver.
    2. I-inthanethi yesathelayithi: Ezinhlelweni ze-inthanethi yesathelayithi, ama-amplifier asetshenziselwa ukwamukela idatha ye-inthanethi edluliselwa kusuka kumasathelayithi. Imishini yomsebenzisi ithola idatha nge-LNB bese iyikhipha bese iyicubungula ngemodemu.
    3. Ukuxhumana Ngesathelayithi: Ama-RF amplifiers asetshenziswa kabanzi ezinhlelweni ezahlukene zokuxhumana ngesathelayithi, okuhlanganisa amafoni esathelayithi, ukusakazwa kwesathelayithi, ukudluliswa kwedatha yesathelayithi, njll. Asiza ekwamukeleni nasekucubunguleni izinhlobo ezahlukene zezimpawu zokuxhumana ezithunyelwa ngamasathelayithi.
    4. Ukubuka Umhlaba Nokuzwa Kude: Kwezinye izinhlelo zokusebenza zokubuka Umhlaba nokuzwa kude, ama-amplifier e-microwave asetshenziselwa ukwamukela idatha yokuzwa kude edluliselwa kumasathelayithi. Le datha ingasetshenziswa ekuqapheni isimo sezulu, ekuqapheni imvelo, ekuxwayiseni ngenhlekelele nakwezinye izinkambu.
    Ngamafuphi, ama-LNB adlala indima ebalulekile ezinhlelweni zokuxhumana zesathelayithi zanamuhla futhi asetshenziswa kabanzi ekusakazeni kuthelevishini, ekufinyeleleni i-inthanethi, ekuxhumaneni kwedatha kanye nasezindaweni ezahlukene zobungcweti.

    I-QualwaveIhlinzeka ngezinhlobo ezahlukene zama-Block Downconverters (ama-LNB) ku-S~Ka-Band, ngokushisa komsindo okungu-45~240K. Ukuphela komsindo okuhlukile ukuhlangabezana nezidingo zamakhasimende.
