    • I-Broad Band Low Noise Temperature Okokufaka Okuphansi kwe-VSWR Vimba Iziguquli Eziphansi (LNBs)

    Izici:

    • Ibhendi Ebanzi
    • Low Noise Temperature
    • Okokufaka okuphansi kwe-VSWR

    Izicelo:

    • Isiteshi Esigxilile
    • Isiteshi Esihambayo
    • Ukuhlolwa Kwelabhorathri

    Vimba i-Downconverters (LNBs)

    Ezinhlelweni zokuxhumana, ukuze kube lula ukudluliswa kwesignali nokuzuza ukusetshenziswa kabusha kwesiteshi, imvamisa yamasignali adluliswayo iphezulu kakhulu, ngakho ukuguqulwa kwemvamisa kwamasignali kuyisici esibalulekile socwaningo lwesistimu yezokuxhumana. Ngokwesimo ngaphambi nangemuva kokuguqulwa kwefrikhwensi, ingahlukaniswa ibe ukuguqulwa okuphansi (ukunciphisa imvamisa) nokuguqulwa okuphezulu (ukwenyuka kwemvamisa).
    Kumamukeli, uma isignali yefrikhwensi emaphakathi etholwe ngemva kokuxuba iphansi kunesiginali yokuqala, khona-ke le ndlela yokuxuba ibizwa ngokuthi i-block downconverters (LNBs).
    Indlela ye-block downconverters iwukuphindaphinda isignali etholiwe ngesignali ye-oscillator yendawo eyenziwe yi-oscillator yendawo, bese uthola isignali eguquliwe ngokusebenzisa isihlungi se-low-pass. Izimpawu ezimbili eziphindaphindekayo zingahlukaniswa zibe ukuxuba kwangempela kanye nokuxuba okuyinkimbinkimbi ngokusebenzisa ukumelwa kwangempela noma okuyinkimbinkimbi.
    Inhloso ye-block downconverters ukunciphisa imvamisa yenkampani yenethiwekhi noma ukususa ngokuqondile imvamisa yenkampani yenethiwekhi ukuze kutholwe isignali ye-baseband. Ngenxa yomjikelezo wayo olula kanye nezindleko eziphansi, indlela yokuguqula phansi isetshenziswa kakhulu ezintweni ezisetshenziswa umphakathi kanye nempahla yezempi enezidingo zokusebenza eziphansi.

    Isicelo:

    1. I-TV yesathelayithi: Ama-LNB ayizingxenye ezibalulekile ezinhlelweni zokwamukela i-TV yesathelayithi. Zifakwa endaweni okugxilwe kuyo i-antenna yesathelayithi (i-paraboloid noma isitsha), zithole isignali ye-TV esakazwa yisathelayithi, futhi iyiguqule ibe isignali yefrikhwensi emaphakathi engacutshungulwa ngumuntu owamukelayo.
    2. I-inthanethi Yesathelayithi: Kuzinhlelo ze-inthanethi zesathelayithi, ama-LNB asetshenziselwa ukwamukela idatha ye-inthanethi ethunyelwa kumasathelayithi. Okokusebenza komsebenzisi kuthola idatha nge-LNB futhi ihlukanise futhi iyicubungule ngemodemu.
    3. Ukuxhumana Ngesathelayithi: Ama-LNB asetshenziswa kakhulu ezinhlelweni ezihlukahlukene zokuxhumana ngesathelayithi, okuhlanganisa amafoni asethelayithi, ukusakazwa kwesathelayithi, ukudluliswa kwedatha ngesathelayithi, njll. Asiza ukwamukela nokucubungula izinhlobo ezihlukahlukene zezimpawu zokuxhumana ezithunyelwa kumasathelayithi.
    4. Ukubhekwa Komhlaba kanye Nokuzwa Kukude: Kwezinye izinhlelo zokusebenza zokubuka umhlaba nezenzwa ukude, ama-LNB asetshenziselwa ukwamukela idatha yenzwa yesilawuli kude ethunyelwa kumasathelayithi. Le datha ingasetshenziswa ekuqaphelweni kwesimo sezulu, ekuqaphelweni kwemvelo, ekuxwayiseni ngezinhlekelele neminye imikhakha.
    Kafushane, ama-LNB adlala indima ebalulekile ezinhlelweni zesimanje zokuxhumana ngesathelayithi futhi asetshenziswa kakhulu ekusakazeni komabonakude, ekufinyeleleni ku-inthanethi, ezokuxhumana ngedatha kanye nasezinkundleni ezihlukahlukene zobungcweti.

    Qualwaveinikeza izinhlobo ezahlukene zama-Block Downconverters (LNB) ku-S~Ka-Band, ngezinga lokushisa lomsindo elingu-45~240K. Ukunqanyulwa ngohlobo oluhlukile ukuze kuhlangatshezwane nezidingo zamakhasimende.
