Imodyuli ye-RF yangaphambili: amandla okuqhuba angundoqo kwixesha le-5G

Imodyuli ye-RF front-end (FEM) idlala indima ebalulekileyo kunxibelelwano lwale mihla olungenazingcingo, ngakumbi kwixesha le-5G. Ubukhulu becala iqulunqwe ngamacandelo aphambili anjenge-amplifier yamandla (PA),isihluzo,duplexer, RF switch kunyeisandisi-lizwi esisezantsi (LNA)ukuqinisekisa amandla, uzinzo kunye nomgangatho wesiginali.

I-amplifier yamandla inoxanduva lokukhulisa umqondiso weRF, ngakumbi kwi-5G, efuna ukusebenza kakuhle okuphezulu kunye nomgca ophezulu. Isihluzi sikhetha isiginali ethile yokuhluza imiqondiso yophazamiseko ukuqinisekisa ukusulungeka kokuhanjiswa komqondiso. Kwibhendi yefrikhwensi ephezulu, i-surface acoustic wave (SAW) kunye ne-bulk acoustic wave (BAW) izihluzi zineenzuzo zazo kunye nokungalunganga. Izihluzi ze-BAW zisebenza ngcono kwibhendi yefrikhwensi ephezulu, kodwa ixabiso liphezulu.

Iduplexerixhasa inkqubo yonxibelelwano ye-frequency division duplex (FDD) ukuqinisekisa ukusebenza kakuhle konxibelelwano lweendlela ezimbini, ngelixa iswitshi yeRF inoxanduva lokutshintsha indlela yomqondiso, ngakumbi kwimo engqongileyo ye-5G ye-multi-band, efuna ilahleko ephantsi yokufaka kunye nokutshintsha ngokukhawuleza. Iisandisi-lizwi esisezantsiiqinisekisa ukuba isignali ebuthathaka efunyenweyo ayiphazanyiswa yingxolo.

Ngophuhliso lwetekhnoloji ye-5G, iimodyuli ze-RF zangaphambili zihambela ekudityanisweni kunye ne-miniaturization. Ipakethe yetekhnoloji yokupakisha ye-SiP ipakisha amacandelo amaninzi e-RF kunye, iphucula ukudityaniswa kunye nokunciphisa iindleko. Ngelo xesha, ukusetyenziswa kwezinto ezintsha ezifana ne-liquid crystal polymer (LCP) kunye ne-polyimide eguquliweyo (MPI) kwintsimi ye-antenna iphucula ngakumbi ukuhanjiswa kwesignali.

Ukuveliswa kweemodyuli ze-RF zangaphambili zikhuthaze inkqubela phambili yonxibelelwano lwe-5G, kwaye iya kuqhubeka idlala indima ephambili kunxibelelwano olungenazingcingo kwixesha elizayo, lizisa amathuba amaninzi ophuhliso lobuchwepheshe.
