Ezinhlelweni zokuxhumana zesimanje, i-Radio Frequency (RF) engaphambili idlala indima ebalulekile ekwenzeni ukuxhumana okungenantambo kube okusebenzayo. Ibekwe phakathi kwe-antenna ne-digital baseband, i-RF front-end inesibopho sokucubungula amasignali angenayo naphumayo, okuyenza ibe yingxenye ebalulekile kumadivayisi asukela kuma-smartphones kuya kumasathelayithi.
Iyini i-RF Front-End?
I-RF front-end iqukethe izingxenye ezihlukahlukene eziphethe ukwamukela isignali nokudlulisa. Izinto ezibalulekile zifaka izikhulisamandla (PA), izikhulisamsindo eziphansi (LNA), izihlungi, namaswishi. Lezi zingxenye zisebenza ndawonye ukuze kuqinisekiswe ukuthi amasignali adluliselwa ngamandla afunekayo nokucaca, kuyilapho kunciphisa ukuphazamiseka nomsindo.
Imvamisa, zonke izingxenye eziphakathi kwe-antenna ne-transceiver ye-RF zibizwa ngokuthi yi-RF front-end, okuqinisekisa ukudluliswa kwesignali okungenazintambo okuphumelelayo.
2) Ukuhlelwa kanye nomsebenzi we-RF Front-End
I-RF front-end ingahlukaniswa ngezinhlobo ezimbili ezinkulu ngokusekelwe kwayo Ngokwefomu: izingxenye ezihlukene kanye namamojula e-RF. Izingxenye ezihlukene zihlukaniswa futhi ngokusekelwe emsebenzini wazo, kuyilapho amamojula e-RF ehlukaniswa ngamaleveli aphansi, aphakathi nendawo, naphezulu okuhlanganisa. Ukwengeza, kuye ngendlela yokudlulisa isignali, isiphetho se-RF sihlukaniswe izindlela zokudlulisela kanye nokwamukela.
Kusukela ekuhlukaniseni okusebenzayo kwamadivayisi ahlukene, izingxenye ezibalulekile ze-RF front-end zifaka phakathi ihlukaniswe yaba i-amplifier yamandla (PA), i-duplexer (i-Duplexer ne-Diplexer), i-radio frequency switch (Shintsha), isihlungi (Isihlungi) kanye nesandisi somsindo ophansi (LNA), njll.,. Lezi zingxenye, kanye ne-baseband chip, zakha uhlelo oluphelele lwe-RF.
Ama-Amplifaya Amandla (PA): Qinisa isignali edluliswayo.
Ama-Duplexer: Amasiginali ahlukene okudlulisela kanye nokwamukela, okuvumela amadivaysi ukuthi abelane ngothi olufanayo ngempumelelo.
Ukushintsha kwefrikhwensi yomsakazo (Shintsha): Vumela ukushintsha phakathi kokudlulisela nokwamukela noma phakathi kwamabhendi amafrikhwensi ahlukene.
Izihlungi: Hlunga amaza angafuneki futhi ugcine isignali oyifunayo.
Izikhulisamsindo eziphansi (LNA): Khulisa amasiginali abuthakathaka endleleni eyamukelayo.
Amamojula e-RF, asekelwe ezingeni lawo lokuhlanganiswa, asukela kumamojula ahlanganisiwe aphansi (afana ne-ASM, i-FEM) kuya kumamojula ahlanganisa amaphakathi (njenge-Div FEM, FEMID, PAiD), kanye namamojula ahlanganisa kakhulu (afana ne-PAMiD, LNA Div FEM ). Uhlobo ngalunye lwemojuli yakhelwe ukuhlangabezana nezidingo ezahlukene zohlelo lokusebenza.
Ukubaluleka Ezinhlelweni Zokuxhumana
I-RF front-end iyisivikeli esiyinhloko sokuxhumana okungenazintambo okuphumelelayo. Inquma ukusebenza kwesistimu kukonke mayelana namandla esignali, ikhwalithi, nomkhawulokudonsa. Kumanethiwekhi amaselula, isibonelo, i-RF front-end iqinisekisa ukuxhumana okucacile phakathi kwedivayisi nesiteshi sesisekelo, okunomthelela ngokuqondile kwikhwalithi yekholi, isivinini sedatha, kanye nobubanzi bokutholakala.
Izixazululo Zangokwezifiso ze-RF Front-End
I-Apex igxile ekuklameni izingxenye zangaphambili ze-RF, enikeza izixazululo eziklanyelwe ukuhlangabezana nezidingo ezithile zezinhlelo zokuxhumana ezihlukene. Uhlu lwethu lwemikhiqizo engaphambili ye-RF luqinisekisa ukusebenza okuthuthukisiwe kwezinhlelo zokusebenza kwezokuxhumana ngocingo, i-aerospace, ezokuvikela, nokunye.
Isiphetho
I-RF front-end iyingxenye ebalulekile yanoma yiluphi uhlelo lwezokuxhumana, iqinisekisa ukudluliswa kwesignali ngendlela ephumelelayo nokwamukela kuyilapho kunciphisa ukuphazamiseka. Ngokuthuthuka kwezobuchwepheshe kanye nezidingo ezikhulayo zokusebenza okuphezulu, ukubaluleka kwezixazululo ze-RF zekhwalithi ephezulu kuyaqhubeka nokukhuphuka, okuzenza zibe yingxenye ebalulekile yamanethiwekhi angenantambo esimanje.
