    IiBlock Downconverters (ii-LNB)

    Kwiinkqubo zonxibelelwano, ukuze kube lula ukuhanjiswa kwesignali kunye nokufezekisa ukusetyenziswa kwakhona kwetshaneli, imvamisa yesignali ezidluliselwayo iphezulu kakhulu, ngoko ke ukuguqulwa kwemvamisa yesignali luphawu olubalulekileyo kuphando lwenkqubo yonxibelelwano. Ngokwemeko yangaphambi nasemva kokuguqulwa kwemvamisa, inokwahlulwa ibe kukuguqulwa kwe-down (ukunciphisa imvamisa) kunye nokuguqulwa kwe-up (ukwanda kwemvamisa).
    Kwi-receiver, ukuba isignali ye-frequency ephakathi efunyenwe emva kokuxuba iphantsi kunesignali yokuqala, ke le ndlela yokuxuba ibizwa ngokuba yi-block downconverters (ii-LNB).
    Indlela ye-block downconverters kukuphindaphinda isignali efunyenweyo ngesignali ye-oscillator yendawo eveliswa yi-oscillator yendawo, uze ufumane isignali eguquliweyo ngesihluzi esidlula phantsi. Imiqondiso emibini ephindaphindwe kabini inokwahlulwa ibe kukuxubana kwangempela kunye nokuxubana okuntsonkothileyo ngokumelwa kwangempela okanye okuntsonkothileyo.
    Injongo yee-block downconverters kukunciphisa i-carrier frequency yesignali okanye ukususa ngokuthe ngqo i-carrier frequency ukuze ufumane i-baseband signal. Ngenxa yesekethe yayo elula kunye nexabiso eliphantsi, indlela yokuguqula i-down isetyenziswa kakhulu kwizixhobo zaseburhulumenteni nakwizixhobo zomkhosi ezineemfuno zokusebenza eziphantsi.

    Isicelo:

    1. I-TV yesathelayithi: Ii-LNB zizinto ezibalulekileyo kwiinkqubo zokwamkela iTV yesathelayithi. Zifakelwa kwindawo ephambili ye-antenna yesathelayithi (i-paraboloid okanye isitya), zamkela isignali yeTV ethunyelwa yisathelayithi, kwaye ziyiguqule ibe sisignali yefrikhwensi ephakathi enokucutshungulwa yi-receiver.
    2. I-Intanethi yeSathelayithi: Kwiinkqubo ze-Intanethi yesathelayithi, ii-amplifier zisetyenziselwa ukufumana idatha ye-Intanethi ethunyelwa kwiisathelayithi. Izixhobo zomsebenzisi zifumana idatha nge-LNB kwaye ziyiguqule kwaye ziyicubungule ngemodem.
    3. Unxibelelwano lweSatellite: Ii-RF amplifiers zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo zonxibelelwano lwesathelayithi, kuquka iifowuni zesathelayithi, usasazo lwesathelayithi, uthumelo lwedatha yesathelayithi, njl. Zinceda ekufumaneni nasekucubunguleni iintlobo ezahlukeneyo zemiqondiso yonxibelelwano ethunyelwa kwiisathelayithi.
    4. Ukujonga Umhlaba kunye nokuSeva okukude: Kwezinye iinkqubo zokujonga uMhlaba kunye nokuSeva okukude, ii-amplifiers ze-microwave zisetyenziselwa ukufumana idatha yokuSeva okukude ethunyelwa kwiisathelayithi. Ezi datha zingasetyenziswa ekujongeni imozulu, ekujongeni okusingqongileyo, kwizilumkiso zentlekele nakwezinye iinkalo.
    Ngamafutshane, ii-LNB zidlala indima ebalulekileyo kwiinkqubo zonxibelelwano lwesathelayithi zanamhlanje kwaye zisetyenziswa kakhulu kusasazo lukamabonwakude, ukufikelela kwi-intanethi, unxibelelwano lwedatha kunye namacandelo ahlukeneyo obuchwephesha.

    I-QualwaveIbonelela ngeentlobo ezahlukeneyo zeeBlock Downconverters (ii-LNB) kwi-S~Ka-Band, enobushushu bengxolo obuyi-45~240K. Iziphelo zohlobo olwahlukileyo ukuhlangabezana neemfuno zabathengi.
