Vimba ii-Downconverters (LNBs)

Kwiinkqubo zonxibelelwano, ukwenzela ukuba kube lula ukuhanjiswa komqondiso kunye nokufezekisa ukusetyenziswa kwakhona kwetshaneli, ukuphindaphinda kweempawu ezithunyelwayo kuphezulu kakhulu, ngoko ke ukuguqulwa kwamaza okwenziwa kwemiqondiso yinto ebalulekileyo yophando lwenkqubo yonxibelelwano. Ngokwemeko ngaphambi nangemva kokuguqulwa kwamaza, inokwahlulwa ibe yi-conversion ephantsi (ukunciphisa i-frequency) kunye nokuguqulwa okunyukayo (ukunyuka kwamaxesha).
Kwi-receiver, ukuba i-intermediate frequency signal efunyenwe emva kokuxuba iphantsi kunomqondiso wokuqala, ke le ndlela yokuxuba ibizwa ngokuba yi-block downconverters (LNBs).
Indlela ye-block downconverters kukuphindaphinda umqondiso ofunyenweyo kunye nomqondiso we-oscillator wendawo owenziwe yi-oscillator yendawo, kwaye emva koko ufumane isignali eguqulwayo ngokusebenzisa isihlungi esisezantsi. Iimpawu ezimbini eziphindaphindwayo zinokwahlulwa zibe yingxubevange yokwenyani kunye nokuxuba okuntsonkothileyo ngokumelwa okuyinyani okanye okuntsokothileyo.
Injongo ye-block downconverters kukunciphisa i-frequency carrier ye-signal okanye ukususa ngokuthe ngqo i-frequency carrier ukuze ufumane isignali ye-baseband. Ngenxa yesekethe elula kunye neendleko eziphantsi, indlela yokuguqula ephantsi isetyenziswa ngokubanzi kwizixhobo zoluntu kunye nezixhobo zomkhosi ezineemfuno zokusebenza eziphantsi.

Isicelo:

1. I-TV yesathelayithi: Ii-LNB ngamacandelo aphambili kwiisistim zesathelayithi zokwamkela umabonakude. Zifakwe kwindawo ekugxilwe kuyo kwi-antenna yesathelayithi (i-paraboloid okanye isitya), yamkela isignali ye-TV ehanjiswa yisathelayithi, kwaye iyiguqule ibe ngumqondiso ophakathi onokuthi uqhutywe ngumamkeli.
2. I-Intanethi yeSathelayithi: Kwiinkqubo ze-Intanethi zesathelayithi, ii-amplifiers zisetyenziselwa ukufumana idatha ye-Intanethi ethunyelwa kwiisathelayithi. Isixhobo somsebenzisi sifumana idatha nge-LNB kwaye siyicazulule kwaye siyiqhube ngemodem.
3. UNxibelelwano ngeSathelayithi: Izandisi zeRF zisetyenziswa kakhulu kwiinkqubo ezahlukeneyo zonxibelelwano ngesathelayithi, kuquka iifowuni zesathelayithi, usasazo lwesathelayithi, ukuhanjiswa kwedatha ngesathelayithi, njl.
4. UkuJongwa koMhlaba kunye neSensing Sensing: Kolunye uphononongo lwe-Earth kunye ne-remote sensing applications, ii-microwave amplifiers zisetyenziselwa ukufumana i-remote sensing data ethunyelwa kwiisathelayithi. Ezi nkcukacha zingasetyenziselwa ukubeka iliso kwimozulu, ukubeka iliso kokusingqongileyo, isilumkiso sentlekele kunye nezinye iinkalo.
Ngamafutshane, ii-LNBs zidlala indima ebalulekileyo kwiisistim zonxibelelwano ngesathelayithi zanamhlanje kwaye zisetyenziswa kakhulu kusasazo lukamabonakude, ukufikelela kwi-Intanethi, kunxibelelwano lwedatha nakwiinkalo ezahlukeneyo zobuchwephesha.

Qualwaveibonelela ngeentlobo ezahlukeneyo zeBlock Downconverters (LNBs) kwi-S~Ka-Band, ngeqondo lobushushu lengxolo le-45~240K. Ukupheliswa ngodidi olwahlukileyo ukuhlangabezana neemfuno zabathengi.
