A cikin tsarin sadarwa mara waya, akwai abubuwa guda huɗu: eriya, gaban-ƙarshe na mitar rediyo (RF), na'urar watsa siginar RF, da kuma na'urar sarrafa siginar baseband.
Da zuwan zamanin 5G, buƙata da ƙimar eriya da kuma RF front-ends sun tashi da sauri. RF front-end shine babban ɓangaren da ke canza siginar dijital zuwa siginar RF mara waya, kuma shine babban ɓangaren tsarin sadarwa mara waya.
A aiki, ana iya raba ƙarshen RF zuwa ɓangaren watsawa (Tx) da ɓangaren karɓa (Rx).
● Tace: Yana zaɓar takamaiman mitoci kuma yana tace siginar tsangwama
● Mai Duplexer/Multiplexer: Siginar da aka watsa/karɓa tana rabawa
● Mai ƙara ƙarfin lantarki (PA): Yana ƙara ƙarfin siginar RF don watsawa
● Ƙaramin Ƙararrawa Mai Sauti (LNA): Yana ƙara girman siginar da aka karɓa yayin da yake rage girman hayaniyar
● Maɓallin RF: Yana sarrafa kunnawa/kashe da'ira don sauƙaƙe sauyawar sigina
● Mai gyara: Daidaita impedance don eriya
● Sauran abubuwan haɗin RF na gaba
Ana amfani da na'urar bin diddigin amfilifa mai ƙarfi (ET) don inganta ingancin amfilifa mai ƙarfi don sigina masu matsakaicin rabon ƙarfi zuwa matsakaici ta hanyar ba da damar fitarwa masu ƙarfin daidaitawa.
Idan aka kwatanta da dabarun bin diddigin wutar lantarki na matsakaici, bin diddigin ambulaf yana bawa ƙarfin wutar lantarki na amplifier wutar lantarki damar bin diddigin siginar shigarwa, yana inganta ingantaccen makamashin amplifier wutar lantarki ta RF.
Mai karɓar RF yana canza siginar RF da aka karɓa ta hanyar eriya ta hanyar abubuwan da aka haɗa kamar matattara, LNAs, da masu sauya analog-zuwa-dijital (ADCs) don rage juyawa da rage siginar, a ƙarshe yana samar da siginar baseband azaman fitarwa.
Kamfanin Concept Microwave ƙwararre ne wajen kera kayan haɗin 5G RF a ƙasar Sin, waɗanda suka haɗa da matatar RF mai ƙarancin wucewa, matatar highpass, matatar bandpass, matatar notch/band stop filter, duplexer, mai raba wutar lantarki da kuma mahaɗin jagora.
