IkhathalogiI-RF front-end module (FEM) idlala indima ebalulekile ekuxhumaneni okungenantambo kwesimanje, ikakhulukazi enkathini ye-5G. Yakhiwe kakhulu yizingxenye ezibalulekile njenge-power amplifier (PA),isihlungi,i-duplexer, iswishi ye-RF kanyei-amplifier yomsindo ophansi (i-LNA)ukuqinisekisa amandla, ukuzinza kanye nekhwalithi yesiginali.
I-amplifier yamandla inesibopho sokukhulisa isignali ye-RF, ikakhulukazi ku-5G, okudinga ukusebenza kahle okuphezulu kanye nokulingana okuphezulu. Isihlungi sikhetha isignali ethile yemvamisa ukuze sihlunge amasignali okuphazamiseka ukuqinisekisa ubumsulwa bokudluliselwa kwesignali. Kubhendi yemvamisa ephezulu, izihlungi ze-surface acoustic wave (SAW) kanye ne-bulk acoustic wave (BAW) zinezinzuzo nezinkinga zazo. Izihlungi ze-BAW zisebenza kangcono kubhendi yemvamisa ephezulu, kodwa izindleko ziphakeme.
Ii-duplexerisekela uhlelo lokuxhumana lwe-frequency division duplex (FDD) ukuqinisekisa ukusebenza kahle kokuxhumana okunezindlela ezimbili, kuyilapho i-RF switch inesibopho sokushintsha indlela yesignali, ikakhulukazi endaweni ye-5G multi-band, edinga ukulahlekelwa okuphansi kokufakwa kanye nokushintsha okusheshayo.isikhulisi somsindo ophansikuqinisekisa ukuthi isignali ebuthakathaka eyamukelwe ayiphazanyiswa umsindo.
Ngokuthuthuka kobuchwepheshe be-5G, amamojula we-RF front-end aya phambili ekuhlanganisweni nasekunciphisweni kwe-aturization. Ubuchwepheshe bokupakisha be-SiP buhlanganisa izingxenye eziningi ze-RF ndawonye, buthuthukisa ukuhlanganiswa futhi bunciphisa izindleko. Ngesikhathi esifanayo, ukusetshenziswa kwezinto ezintsha ezifana ne-liquid crystal polymer (LCP) kanye ne-modified polyimide (MPI) ensimini ye-antenna kuthuthukisa kakhulu ukusebenza kahle kokudluliselwa kwesignali.
Ukusungulwa kwamamojula e-RF front-end kukhuthaze intuthuko yokuxhumana kwe-5G, futhi kuzoqhubeka nokudlala indima ebalulekile ekuxhumaneni okungenantambo esikhathini esizayo, okuletha amathuba engeziwe okuthuthukiswa kobuchwepheshe.
