Isishwankathelo
Isihluli samandla esineendlela ezintathu sisixhobo esibalulekileyo esisetyenziswa kwiinkqubo zonxibelelwano ezingenazingcingo kunye neesekethe zeRF. Siqulathe i-input port enye kunye nee-output ports ezintathu, ezisetyenziselwa ukwabela imiqondiso yokufaka kwii-output ports ezintathu. Sifezekisa ukwahlulwa kwesignali kunye nokusasazwa kwamandla ngokufezekisa ukusasazwa kwamandla okufanayo kunye nokusasazwa kwesigaba esingaguqukiyo. Ngokuqhelekileyo kufuneka ukuba ibe nokusebenza kakuhle kwamaza okuma, ukuhlukaniswa okuphezulu, kunye nokuba semgangathweni kwebhendi.
Izalathisi eziphambili zobugcisa zesixhobo sokwahlula amandla esineendlela ezintathu luluhlu lweefrikhwensi, ukumelana namandla, ilahleko yokwabiwa, ilahleko yokufakwa phakathi kokufakwa kunye nokuphuma, ukwahlulwa phakathi kweeports, kunye nomlinganiselo wamaza amileyo weport nganye.
Izihluzi zamandla ezi-3-way zisetyenziswa kakhulu kwiinkqubo zonxibelelwano ezingenazingcingo nakwiisekethe ze-RF. Zisetyenziswa rhoqo kwiindawo ezifana neenkqubo zesikhululo seenqwelo-moya, ii-antenna arrays, kunye neemodyuli ze-RF front-end.
Isixhobo esihlukanisa amandla esineendlela ezintathu sisixhobo esiqhelekileyo seRF, kwaye iimpawu zaso eziphambili kunye neenzuzo ziquka:
Ukusasazwa okufanayo: Isihluli samandla esineetshaneli ezi-3 sinokusasaza ngokulinganayo imiqondiso yokufaka kwiizibuko ezintathu zokukhupha, sifezekise ukusasazwa okuqhelekileyo kwesignali. Oku kuluncedo kakhulu kwizicelo ezifuna ukufunyanwa okanye ukudluliselwa kwemiqondiso emininzi efanayo ngaxeshanye, njengeenkqubo ze-antenna array.
I-Broadband: Izihluzi zamandla ezineetshaneli ezi-3 zihlala zinoluhlu olubanzi lweefrikhwensi kwaye zinokugubungela uluhlu olubanzi lweefrikhwensi. Oku kuzenza zilungele usetyenziso lweRF ezahlukeneyo, kubandakanya iinkqubo zonxibelelwano, iinkqubo zeradar, izixhobo zokulinganisa, njl.
Ukulahleka okuphantsi: Uyilo oluhle lokwahlula amandla lunokwenza ukuba ukufakwa kube buthathaka kakhulu. Ukulahleka okuphantsi kubaluleke kakhulu, ingakumbi kwiinkqubo zokudlulisa isignali kunye nokwamkela ezisebenzisa amaxesha amaninzi, njengoko kunokuphucula ukusebenza kakuhle kokudluliselwa kwesignali kunye novakalelo lokwamkela.
Ukuhlukaniswa okuphezulu: Ukuhlukaniswa kubhekisa kwinqanaba lokuphazamiseka kwesignali phakathi kwee-output ports ze-power divider. I-power divider eneendlela ezintathu idla ngokubonelela ngokuhlukaniswa okuphezulu, ukuqinisekisa ukuphazamiseka okuncinci phakathi kwesignali ezivela kwii-output ports ezahlukeneyo, ngaloo ndlela kugcinwa umgangatho wesignali olungileyo.
Ubungakanani obuncinci: Indlela ezintathu ezahlula amandla zihlala zisebenzisa uyilo oluncinci lokupakisha kunye nolwakhiwo, ngobukhulu obuncinci kunye nomthamo. Oku kuvumela ukuba zidityaniswe ngokulula kwiinkqubo ezahlukeneyo zeRF, okonga indawo kunye nokuphucula ukusebenza kwenkqubo iyonke.
Abathengi banokukhetha i-frequency kunye ne-power divider efanelekileyo ngokweemfuno ezithile zesicelo, okanye banxibelelane ngokuthe ngqo nabasebenzi bethu bezentengiso ukuze bafumane ulwazi oluthe vetshe kunye nokuthenga.
