Iziteshi zokuxhumana zesathelayithi

Ukusetshenziswa okuyinhloko kwama-antenna nama-amplifier eziteshini zokuxhumana zesathelayithi yilena elandelayo:

1. I-Antenna: Izimpawu zokuxhumana ngesathelayithi zidinga ukudluliselwa kusuka ku-antenna yomhlaba kuya ku-satellite kanye nokusuka ku-satellite kuya phansi. Ngakho-ke, i-antenna iyisici esibalulekile ekudluliseni isignali, engagxila isignali endaweni ethile futhi ithuthukise amandla nekhwalithi yesignali.

2. I-Amplifier: Isignali iyancishiswa ngesikhathi sokudlulisa, ngakho-ke i-amplifier iyadingeka ukwandisa amandla esignali nokuqinisekisa ukuthi isignali ingafinyelela kuma-satellite kanye nama-ground receiver. I-amplifier esetshenziswa eziteshini zokuxhumana zesathelayithi ngokuvamile iyi-amplifier yomsindo ophansi (i-LNA), enezici zomsindo ophansi kanye nokuzuza okuphezulu, okungathuthukisa ukuzwela kwesignali etholakele. Ngesikhathi esifanayo, i-amplifier ingasetshenziswa futhi ekugcineni kwe-transmitter ukukhulisa isignali ukuze kufezwe ibanga elide lokudlulisa. Ngaphezu kwama-antenna nama-amplifier, iziteshi zokuxhumana zesathelayithi zidinga ezinye izingxenye, njengezintambo ze-RF kanye nezishintshi ze-RF, ukuqinisekisa ukudluliselwa kwesignali okubushelelezi nokulawula.
