    Vimba ama-downConverterers (LNBs)

    Kwezinhlelo Zokuxhumana, ukuze kusebenze ukudluliswa kwesiginali futhi uzuze ukusetshenziswa kabusha kwesiteshi, imvamisa yezimpawu ezidlulisiwe ziphezulu kakhulu, ngakho-ke ukuguqulwa imvamisa kwezimpawu kuyisici esibalulekile socwaningo lwezokuxhumana. Ngokwesimo ngaphambi nangemva kokuguqulwa imvamisa, ingahlukaniswa ngokuguqulwa okuphansi (ukuncishiswa imvamisa) nokuguqulwa okuphezulu (ukukhuphuka imvamisa).
    Esivumelwaneni, uma isinali eliphakathi nendawo eliphakathi litholwe ngemuva kokuxubana liphansi kunesiginali yasekuqaleni, khona-ke le ndlela yokuxuba ibizwa nge-block downConverTerers (LNBS).
    Indlela ye-block downconverters ukwandisa isiginali etholakele ngesiginali ye-Oscillator yendawo ekhiqizwe i-Oscillator yendawo, bese uthola isiginali eguquliwe ngokusebenzisa isihlungi esingezansi. Izimpawu ezimbili ezandisiwe zingahlukaniswa zaba ukuxuba kwangempela nokuxubana okuyinkimbinkimbi ngokusebenzisa isethulo sangempela noma esiyinkimbinkimbi.
    Inhloso ye-block DownConverters ukunciphisa imvamisa yenkampani yenethiwekhi yesiginali noma isuse ngokuqondile imvamisa yenethiwekhi ukuthola isinali ye-baseband. Ngenxa ye-Circuit yayo elula kanye nezindleko eziphansi, indlela yokuguqula phansi isetshenziswa kabanzi emishini yezempi kanye nemishini yezempi enezidingo eziphansi zokusebenza.

    Isicelo:

    1. I-Tatellite TV: I-LNBS yizakhi ezibalulekile ezinhlelweni ze-satellite TV Reception Systems. Zifakwe endaweni egxile endaweni ye-antenna ye-satellite (paraboloid noma isidlo), yamukela isibonakaliso se-TV esidluliswe yi-satellite, bese uyiguqula ibe isibonakaliso semvamisa esiphakathi esingacutshungulwa nguMsunguli.
    2. I-Satellite Internet: Ku-Satellite Internet Systems, amplifiers asetshenziselwa ukuthola idatha ye-Intanethi edluliselwa kuma-satellites. Imishini yomsebenzisi ithola imininingwane nge-LNB nama-decodots futhi icubungule ngemodemu.
    I-3. Ukuxhumana kwe-satellite: Ama-RF Amplifiers asetshenziswa kabanzi ezinhlelweni zokuxhumana ze-satellite, kufaka phakathi izingcingo ze-satellite, ukusakazwa kwe-satellite kwedatha, njll. Basiza ukwamukela nokucubungula izinhlobo ezahlukahlukene zezimpawu zokuxhumana ezidluliswa kwaSpellite.
    4 Le mininingwane ingasetshenziswa ekuqapheleni kwe-meteorological, ukuqapha imvelo, isexwayiso senhlekelele kanye nezinye izinkambu.
    Ngamafuphi, amaLNBs adlala indima ebalulekile ezinhlelweni zokuxhumana ze-satellite zanamuhla futhi asetshenziswa kabanzi ekusakazweni kwethelevishini, ukufinyelela kwe-inthanethi, ukuxhumana kwedatha kanye nezinkundla ezahlukahlukene zobungcweti.

    QoqaIthola izinhlobo ezahlukahlukene ze-block downConverterers (LNBs) ku-S ~ ka-band, ngokushisa komsindo we-45 ~ 240k. I-terminations ehlukile uhlobo lokuhlangabezana nezidingo zamakhasimende.
