Imodyuli ye-RF yangaphambili: amandla aphambili okuqhuba ixesha le-5G

Imodyuli ye-RF front-end (FEM) idlala indima ebalulekileyo kunxibelelwano lwanamhlanje olungenazingcingo, ingakumbi kwixesha le-5G. Iquka ikakhulu izinto ezibalulekileyo ezifana ne-power amplifier (PA),isihluzo,i-duplexer, iswitshi ye-RF kunyeisandisi-lizwi esiphantsi (i-LNA)ukuqinisekisa amandla, uzinzo kunye nomgangatho wesiginali.

I-power amplifier inoxanduva lokwandisa isignali ye-RF, ingakumbi kwi-5G, efuna ukusebenza kakuhle kunye nomgca ophezulu. Isihluzo sikhetha isignali ethile yefrikhwensi ukuze sihluze imiqondiso yokuphazamiseka ukuqinisekisa ubunyulu bokudluliselwa kwesignali. Kwibhendi yefrikhwensi ephezulu, izihluzi ze-surface acoustic wave (SAW) kunye ne-bulk acoustic wave (BAW) zinezibonelelo kunye neengxaki zazo. Izihluzi ze-BAW zisebenza ngcono kwibhendi yefrikhwensi ephezulu, kodwa ixabiso liphezulu.

Ii-duplexerIxhasa inkqubo yonxibelelwano ye-frequency division duplex (FDD) ukuqinisekisa ukusebenza kakuhle konxibelelwano oluhamba ngeendlela ezimbini, ngelixa i-RF switch inoxanduva lokutshintsha indlela yesignali, ingakumbi kwindawo ye-5G multi-band, efuna ukulahleka okuncinci kokufakwa kunye nokutshintsha ngokukhawuleza.isandisi-lizwi esiphantsiiqinisekisa ukuba isignali ebuthathaka efunyenweyo ayiphazanyiswa yingxolo.

Ngophuhliso lwetekhnoloji ye-5G, iimodyuli ze-RF front-end ziya phambili ekudityanisweni nasekuncitshisweni. Itekhnoloji yokupakisha ye-SiP ipakisha izinto ezininzi ze-RF kunye, iphucula udityaniso kwaye inciphisa iindleko. Kwangaxeshanye, ukusetyenziswa kwezinto ezintsha ezifana ne-liquid crystal polymer (LCP) kunye ne-modified polyimide (MPI) kwicandelo le-antenna kuphucula ngakumbi ukusebenza kakuhle kokudluliselwa kwesignali.

Ukuveliswa kweemodyuli ze-RF front-end kukhuthaze inkqubela phambili yonxibelelwano lwe-5G, kwaye kuya kuqhubeka nokudlala indima ephambili kunxibelelwano olungenazingcingo kwixesha elizayo, nto leyo ezisa amathuba amaninzi ophuhliso lobuchwepheshe.
