Iifrikhwensi zikanomathotholoamalungu okwenziwazisetyenziswa ikakhulu kulwakhiwo lwezikhululo zesiseko senkqubo yonxibelelwano olungenazingcingo, kunye neenkqubo zokusasazwa kwangaphakathi. Ngokukodwa kwisignali engenazintambo kwisakhiwo, kukho iintlobo ezininzi zezicelo kwi-indoor distribution coverage.
Amacandelo okwenziwa kwamaza kanomathotholo adlala indima ekudibaniseni okanye ekusasazeni imiqondiso yeRF kulwakhiwo lwesikhululo esisisiseko kunye neeprojekthi zokusasaza ngaphakathi. Inkqubo yokusasaza yangaphakathi idibanisa okanye yahlula isignali esasazwa sisikhululo esisisiseko ngokusebenzisa amacandelo angenakwenziwa, kwaye isasazeke kwii-eriyali zendawo nganye yokugubungela nge-feeder, ukuze kuphunyezwe ukugutyungelwa okuqhubekayo nokulungileyo kwesiginali yangaphakathi engenazingcingo. Ukuze ufumane ugutyulo olungcono lomqondiso wangaphakathi, le nkqubo yokusasaza idibanisa/ikwahlula umqondiso ogqithiselwa ukusuka kwisikhululo esisezantsi ukuya kwindawo nganye yokhuselo lwee-eriyali kusetyenziswa amacandelo okwenziwa.
Izixhobo ezisetyenziswayo zezona nxalenye ziphambili zenkqubo ye-eriyali yokutya.
Itopology yenkqubo ye-eriyali yodidi oluphezulu ngolu hlobo lulandelayo:
Imiqondiso kanomathotholo yeefomathi ezininzi ithunyelwa sisikhululo ngasinye esisisiseko, zidityaniswe sisixhobo sokwenziwa kunye nemisebenzi edibanisayo enje ngee-multi-frequency combinations okanye iibhulorho, emva koko idluliselwe kwii-eriyali zesilingi okanye ii-hanging eludongeni ezisasazwa kwisakhiwo sonke ngeentambo. Isignali edibeneyo inokuphinda ihlanganiswe ngokuthe ngqo yi-coupler, edibanisa inxalenye yesignali. Ngenxa yokusebenzisa izixhobo ezingaphaya, ilahleko yofakelo lwezixhobo zeplagi iyaqokelelana nto leyo enokubangela ukuthomalaliswa okukhulu kophawu (ukusasaza imiqondiso yeRF kwimigama emide, enokuvelisa ukuthomalalisa okukhulu ngexesha losasazo lwentambo.)
Umqondiso odibeneyo uqhagamshelwe kwi-port ephumayo ye-multi-frequency mixer njenge-splitter yamandla (usebenzisa umdibanisi obuyiselwe umva). Emva kokuba isignali ihluzwe ngumdibanisi we-multi-frequency, ikhutshwa yi-port yokufaka i-multi-frequency mixer. Ngenxa yeempawu zokucoca ibhendi yezibuko ngalinye, la mazibuko akhupha kuphela umqondiso kwibhendi yokusebenza yamatyeli ezibuko ngalinye.
Le miqondiso inokudluliselwa kubaphindaphindi abakhethekileyo bemigangatho eyahlukeneyo: ukunyuswa, ukuphuma, ukudityaniswa, kwaye emva koko kugutyungelwe ukuhlawulela ilahleko kunye nokuthomalalisa umqondiso kwikhonkco, kwaye ekugqibeleni uhlangane neparameters yoyilo lwebhajethi yekhonkco ukuqinisekisa Isiphumo sokugubungela inqaku ngalinye.
Ke njengomvelisi we-RF ye-passive components, i-Jingxin inokukuxhasa ukubayenza ngokwezifiso amalungu okwenziwangokwesicelo. Wamkelekile ukuba uqhagamshelane nathi. Enkosi.
