Nidaamyada isgaarsiinta fiilo la'aanta guud ahaan waxaa ka mid ah afar qaybood: anteeno, inta jeer ee raadiyaha hore, moduleka gudbinta soo noqnoqda raadiyaha, iyo processor-ka signalka baseband.
Markii uu soo baxay xilligii 5G, baahida iyo qiimaha anteenooyinka iyo soo-jeedka hore ee raadiyaha ayaa si xawli ah kor ugu kacaya. Inta jeer ee raadiyaha hore-dhamaadka waa qaybta aasaasiga ah ee u beddesha calaamadaha dhijitaalka ah calaamadaha soo noqnoqda raadiyaha wireless-ka iyo sidoo kale qaybta xudunta u ah nidaamka isgaarsiinta wirelesska.
Marka loo eego shaqada, inta jeer ee hore ee raadiyaha waxaa loo qaybin karaa dhamaadka gudbinta Tx iyo dhamaadka helitaanka Rx.
Marka loo eego aaladaha kala duwan, RF-ga hore-dhamaadka waxaa loo qaybin karaa cod-weyneyaal koronto (kordhinta signalka RF ee dhamaadka gudbinta),filtarrada (shaandhaynta ishaarada ee gudbiyaha iyo dhammaadka qaataha),cod-weyneyaal dhawaq yar (calaamad kor u qaadida dhamaadka aqbalaha, dhimista qaylada), furayaasha (isku beddelka kanaalada kala duwan),Duplexer(xulashada ishaarada, isbarbardhiga shaandhada), tuner (isbarbardhiga kanaalka anteenada), iwm.
Shaandhayso: irridda soo noqnoqoshada gaarka ah iyo shaandhaynta calaamadaha faragelinta
The filterwaa aaladda ugu muhiimsan ee gaarka ah ee RF-ga hore. Waxay u ogolaataa qaybaha soo noqnoqda gaarka ah ee calaamaduhu inay dhex maraan oo ay si weyn u yareeyaan qaybaha kale ee soo noqnoqda, si ay u wanaajiso faragelinta ka-hortagga calaamadda iyo saamiga signal-ilaa-sanqa.
Diplexer/Multiplexer: Go'doominta calaamadaha gudbinta/helidda
The duplexer, sidoo kale loo yaqaan anteenada Duplexer, waxa uu ka kooban yahay laba qaybood oo ah filtarrada band-stop oo leh soo noqnoqoshada kala duwan.
The duplexerAdeegsada shaqada qaybinta soo noqnoqoshada ee baas sare, baas hoose ama band-pass filter si ay ugu oggolaato isla anteeno ama xariiqda gudbinta inay isticmaasho laba waddo oo calaamad ah, taasoo awood u siinaya isla anteenna inay hesho oo gudbiso calaamadaha laba jeer oo kala duwan.
Cod-weyneeye dhawaq hoose(LNA): Waxay kordhisaa ishaarka la helay waxayna yaraynaysaa hordhaca buuqa
The cod-weyneeye dhawaq yarwaa cod-weyneeye leh sawir sanqadh aad u yar. Shaqadeedu waa in ay xoojiso signalka soo noqnoqda raadiyaha daciifka ah ee ay hesho anteenadu oo ay yarayso hordhaca buuqa. LNA waxay si wax ku ool ah u wanaajin kartaa dareenka helista ee qaataha, taas oo kordhinaysa fogaanta gudbinta ee qalabka wax lagu qaado.
