IkhathaloguIzihluzi zeRF, njengezona nxalenye ziphambili zeenkqubo zonxibelelwano ezingenazingcingo, zifezekisa ukulungelelaniswa kophawu kunye nokuphucula umgangatho wothumelo ngokukhetha ngokukhetha iisignali zamaza. Kwihlabathi lanamhlanje eliqhagamshelene kakhulu, indima yeIzihluzi zeRFayinakungahoywa.
Imisebenzi engundoqo kunye neempawu zeIzihluzi zeRF
Izihluzi zeRFinokuphucula ngokukuko ukusebenza kakuhle kweenkqubo zonxibelelwano ngokwala imiqondiso engafunekiyo kunye nokuvumela imiqondiso yefrikhwensi ekujoliswe kuyo ukuba idlule. Zisetyenziswa ngokubanzi kunxibelelwano oluphathwayo, unxibelelwano lwesathelayithi, iradar, kunye nezixhobo ze-Intanethi zezinto (IoT).
Ukwenza okuphezuluIzihluzi zeRFkufuneka ibe nezi mpawu zilandelayo:
Ilahleko yokufaka ephantsi: qinisekisa ukuthomalaliswa komqondiso omncinci ngaphakathi kwebhendi yokugqitha.
Ukwahlukaniswa okuphezulu kunye nokunciphisa i-stopband attenuation: ngokufanelekileyo ukuvala izibonakaliso ezingajoliswanga kunye nokunciphisa ukuphazamiseka.
Ixabiso eliphezulu le-Q: phucula ukukhetha kunye nokuchaneka kwesihluzi.
Ukusebenza kwe-intermodulation (PIM) egqwesileyo: ukunciphisa ukuphazamiseka kwe-signal intermodulation kunye nokuphucula ukuzinza kwenkqubo.
Uyilo lweMiniaturized: ukuziqhelanisa neemfuno zezixhobo zanamhlanje zezakhiwo ezixineneyo ngelixa uqinisekisa amandla okuphatha.
Iintlobo zeIzihluzi zeRF
Ngokusekelwe kwizinto kunye neenkqubo zokuvelisa,Izihluzi zeRFzinokwahlulwa zibe ziindidi ezininzi:
Izihluzi zeCavity
Iifilitha zeDielectric
Izihluzi zeCoaxial
Iifilitha ezicwangcisiweyo
Izihluzi ze-Electroacoustic
Isihluzi ngasinye sineenzuzo ezizodwa kuyilo, ukusebenza kunye neemeko zesicelo, kwaye sinokuhlangabezana neemfuno zeenkqubo ezahlukeneyo zonxibelelwano ezingenazingcingo.
IiNdlela zeMarike
Ngokuthandwa kweenethiwekhi ze-5G kunye nokwanda kwezicelo kwibhendi ye-millimeter wave, imfuno yentengiso yefrikhwensi ephezulu kunye nokusebenza okuphezulu.Izihluzi zeRFikhula ngokuthe ngcembe. Ukongeza, ukunyuka kwezixhobo ze-IoT kukwabonelele ngamathuba amaninzi okuqamba izinto ezintsha zetekhnoloji kwizihluzi zeRF.
Ukubaluleka kweIzihluzi zeRF
Kwiinkqubo zonxibelelwano ezingenazingcingo, indima yeIzihluzi zeRFayiphelelanga ekugqithiseni iisignali ezithile zamaza, kodwa ikwabandakanya ukukhuselwa kwamaza okuphazamiseka kunye nokwandisa umgangatho wesiginali. Izixhobo zale mihla ezingenazingcingo zifuna izihluzi ezenziwe ngeeresonators, ii-waveguides okanye ii-passive components ukuxhasa imisebenzi yazo yonxibelelwano. Sonke isixhobo sixhomekekeIzihluzi zeRFukuqinisekisa ukuhanjiswa okusebenzayo kunye nokuthembeka kwemiqondiso.
Isishwankathelo
Njengenxalenye esisiseko yeenkqubo zonxibelelwano ezingenazingcingo,Izihluzi zeRFdlala indima ephambili ekusebenzeni ngokufanelekileyo kwezixhobo. Ukusuka kwii-smartphones ukuya kwiinkqubo ze-radar ukuya kwii-terminals ze-IoT, iindawo zesicelo zeIzihluzi zeRFzikhula rhoqo. Ngokuhambela phambili kwetekhnoloji kunye nokwanda kwemfuno yonxibelelwano olungenazingcingo,Izihluzi zeRFiya kudlala indima ebaluleke ngakumbi kwimarike yexesha elizayo.
Ukuba ujonge umgangatho ophezuluIsihluzo se-RFIzisombululo, sinokukubonelela ngeendlela ezahlukeneyo ezisemgangathweni okanye ezilungiselelweyo, kwaye sikhaphe iimveliso zakho ngenkonzo yewaranti yeminyaka emithathu! Nceda uzive ukhululekile ukuqhagamshelana nathi ngolwazi oluthe kratya.
