Iziteshi eziyisisekelo zokuxhumana ngesathelayithi

Izinhlelo zokusebenza eziyinhloko zama-antenna nama-amplifiers eziteshini eziyisisekelo zokuxhumana ngesathelayithi zimi kanje:

1. I-Antenna: Izimpawu zokuxhumana ngesathelayithi zidinga ukudluliselwa kusuka othini lwaphansi kuya kusathelayithi futhi ukusuka kusathelayithi zibuyele phansi.Ngakho-ke, i-antenna iyingxenye ebalulekile ekudluliseni isignali, engagxilisa isignali endaweni eyodwa futhi ithuthukise amandla nekhwalithi yesiginali.

2. Isikhulisi: Isignali iyancipha ngesikhathi sokudlulisela, ngakho-ke isikhulisi siyadingeka ukuze kwandiswe amandla esignali futhi kuqinisekiswe ukuthi isignali ingafinyelela isathelayithi kanye nabamukeli baphansi.I-amplifier esetshenziswa eziteshini eziyisisekelo zokuxhumana ngesathelayithi ngokuvamile iyisikhulisamazwi somsindo ophansi (LNA), esinezici zomsindo ophansi kanye nokuzuza okuphezulu, okungathuthukisa ukuzwela kwesignali eyamukelwe.Ngasikhathi sinye, i-amplifier ingasetshenziswa futhi ekugcineni kwesidluliseli ukukhulisa isignali ukuze kuzuzwe ibanga elide lokudlulisela.Ngokungeziwe kuma-antenna nama-amplifiers, iziteshi eziyisisekelo zokuxhumana ngesathelayithi zidinga ezinye izingxenye, njengezintambo ze-RF namaswishi e-RF, ukuze kuqinisekiswe ukudluliswa kwesignali nokulawula okubushelelezi.
