Usetyenziso oluphambili lwee-eriyali kunye ne-amplifiers kwizikhululo ezisisiseko zonxibelelwano lwesathelayithi zezi zilandelayo:
1. I-eriyali: Imiqondiso yonxibelelwano ngesathelayithi kufuneka idluliswe ukusuka kwi-eriyali esemhlabeni ukuya kwisathelayithi kwaye ukusuka kwisathelayithi ukubuyisela emhlabeni. Ngoko ke, i-antenna iyinxalenye ephambili yokuhambisa umqondiso, onokugxininisa umqondiso kwinqanaba elinye kunye nokuphucula amandla kunye nomgangatho wesiginali.
2. I-Amplifaya: Isignali iyancipha ngexesha lokudluliselwa, ngoko ke i-amplifier iyadingeka ukunyusa amandla omqondiso kunye nokuqinisekisa ukuba umqondiso unokufikelela kwi-satellite kunye nabamkeli bomhlaba. I-amplifier esetyenziswe kwizikhululo zesiseko sonxibelelwano lwesathelayithi ngokuqhelekileyo i-low-noise amplifier (LNA), eneempawu zengxolo ephantsi kunye nokuzuza okuphezulu, okunokuphucula uvakalelo lwesignali efunyenweyo. Kwangaxeshanye, iamplifier inokusetyenziswa kwisiphelo se-transmitter ukukhulisa umqondiso ukufezekisa umgama omde wothumelo. Ukongeza kwii-eriyali kunye ne-amplifiers, izikhululo zesiseko sonxibelelwano ngesathelayithi zifuna amanye amacandelo, anje ngeentambo ze-RF kunye nokutshintsha kweRF, ukuqinisekisa ukuhanjiswa nolawulo olugudileyo.
