I-RF front-end module: amandla okushayela ayinhloko enkathi ye-5G

I-RF front-end module (FEM) idlala indima ebalulekile kwezokuxhumana okungenazintambo zesimanje, ikakhulukazi esikhathini se-5G. Ikakhulukazi yakhiwe izingxenye ezibalulekile ezifana nesikhulisi samandla (PA),isihlungi,i-duplexer, ukushintsha kwe-RF kanyeisikhulisi somsindo ophansi (LNA)ukuqinisekisa amandla, ukuzinza kanye nekhwalithi yesiginali.

Isikhulisi samandla sinesibopho sokukhulisa isignali ye-RF, ikakhulukazi ku-5G, edinga ukusebenza kahle okuphezulu kanye nomugqa ophezulu. Isihlungi sikhetha isignali ethile yefrikhwensi ukuze sihlunge amasignali okuphazamisa ukuze kuqinisekiswe ukuhlanzeka kokudluliswa kwesignali. Kubhendi yefrikhwensi ephezulu, izihlungi ze-surface acoustic wave (SAW) kanye ne-bulk acoustic wave (BAW) zinezinzuzo zazo kanye nokubi. Izihlungi ze-BAW zisebenza kangcono kubhendi yefrikhwensi ephezulu, kodwa izindleko ziphezulu.

Ii-duplexerisekela isistimu yokuxhumana ye-frequency division duplex (FDD) ukuze kuqinisekiswe ukusebenza kahle kokuxhumana kwezindlela ezimbili, kuyilapho iswishi ye-RF inesibopho sokushintsha indlela yesiginali, ikakhulukazi endaweni enamabhendi amaningi we-5G, edinga ukulahlekelwa okuphansi kokufaka nokushintsha ngokushesha. Ii-amplifier yomsindo ophansiiqinisekisa ukuthi isignali ebuthakathaka eyamukelwe ayiphazanyiswa umsindo.

Ngokuthuthukiswa kobuchwepheshe be-5G, amamojula angaphambili e-RF aqhubekela ekuhlanganisweni nasekusetshenzisweni okuncane. Ubuchwepheshe bokupakisha be-SiP buhlanganisa izingxenye eziningi ze-RF ndawonye, ​​kuthuthukisa ukuhlanganisa nokunciphisa izindleko. Ngesikhathi esifanayo, ukusetshenziswa kwezinto ezintsha ezifana ne-liquid crystal polymer (LCP) kanye ne-polyimide eguquliwe (MPI) emkhakheni we-antenna kuthuthukisa ukusebenza kahle kokudluliswa kwesignali.

Ukusungulwa kwamamojula we-RF front-end kukhuthaze inqubekelaphambili yezokuxhumana kwe-5G, futhi kuzoqhubeka nokubamba iqhaza elibalulekile kwezokuxhumana okungenantambo esikhathini esizayo, kuletha amathuba amaningi okuthuthukiswa kobuchwepheshe.
