Kuzinhlelo zanamuhla zokuxhumana, imvamisa yomsakazo (i-RF) Front-End zidlala indima ebalulekile ekuvuseni ukuxhumana okungenantambo okusebenzayo. Ibekwe phakathi kwe-antenna kanye ne-baseband yedijithali, i-RF Front-End inesibopho sokucubungula amasiginali angenayo naphumayo, okwenza kube yingxenye ebalulekile kumadivayisi asuka kuma-Smartphones aya kuma-Smartlellites.
Yini i-RF ngaphambili?
Ukuphela kwe-RF Front-End kuqukethe izinto ezahlukahlukene eziphatha ukwamukelwa kwesiginali nokudlulisela. Izinto ezibalulekile zifaka ama-amplifiers wamandla (PA), ama-amplifiers anomsindo ophansi (i-LNA), izihlungi, kanye nokushintsha. Lezi zingxenye zisebenza ngokubambisana ukuqinisekisa ukuthi amasiginali adluliswa ngamandla afiselekayo nokucaca, ngenkathi kunciphisa ukuphazanyiswa kanye nomsindo.
Imvamisa, zonke izingxenye eziphakathi kwe-antenna kanye ne-rf transceiver zibizwa ngokuthi i-RF Front Front, ziqinisekisa ukuhanjiswa kwesiginali okungenantambo.
2) Ukuhlukaniswa kanye nokusebenza kwe-RF ngaphambili-ukuphela
Ukuphela kwe-RF Front-End kungahlukaniswa ngezinhlobo ezimbili ezinkulu ngokusekelwe kulo ngokwalo: Izingxenye ze-Discrete namamojula we-RF. Izakhi ze-discrete ziye zahlukaniswa ngokusekelwe ekusebenzeni kwazo, kanti amamojula we-RF ahlukaniswe ngamazinga aphansi, aphakathi nendawo, nawokuphakama. Ngokwengeziwe, ngokuya ngendlela yokudlulisa yesiginali, i-RF Front-End ihlukaniswe ngezindlela zokudlulisela kanye nokwamukela.
Ukusuka ekuhlukaniseni okusebenzayo kwamadivayisi ahlukile, izingxenye ezibalulekile ze-RF Front Front ezitholakala kwi-Power Amplifier (PA), i-Duplecler (Duplecler ne-Deglixer), i-Radio Frequency switch (Shintsha), i-Thriple),. Lezi zingxenye, kanye ne-babband chip, zakha uhlelo oluphelele lwe-RF.
Amandla Amplifiers (PA): Qinisa isiginali edluliselwa.
AbakwaDidexer
I-Radio Frequency Shintsha (switch): Nika amandla ukushintshana phakathi kokudlulisela kanye nokwamukela noma phakathi kwamabhande ajwayelekile wemvamisa.
Izihlungi: Hlunga amaza angafuneki bese ugcina isiginali oyifunayo.
Ama-amplifiers omsindo aphansi (LNA): Khulisa amasiginali abuthakathaka endleleni etholayo.
Amamojula we-RF, asuselwa ezingeni lokuhlanganiswa kwawo, aqhelelana namamojula wokuhlanganisa aphansi (anjenge-ASM, FEM) kumamojula wokuhlanganisa aphakathi (njenge-Div Fem, amamojula aphezulu (afana ne-Pamid, e-LNA DE DIVEL). Uhlobo ngalunye lwemodyuli lwenzelwe ukufeza izidingo ezihlukile zohlelo lokusebenza.
Ukubaluleka ezinhlelweni zokuxhumana
I-RF Front-End inika amandla amakhulu wokuxhumana okungenantambo. Inquma ukusebenza kohlelo lonke ngokuya ngamandla wesiginali, ikhwalithi, ne-bandwidth. Kumanethiwekhi weselula, ngokwesibonelo, i-RF Front-End iqinisekisa ukuxhumana okucacile phakathi kwensiza nesiteshi sesisekelo, inomthelela ngqo kwikhwalithi yekholi, ijubane ledatha, kanye nobubanzi bedatha.
Izixazululo zangokwezifiso zangokwezifiso ze-RF
I-Apex ibheka ukuklama izingxenye zangokwezifiso zangaphambili ze-RF, okunikeza izixazululo ezihambelana nokuhlangabezana nezidingo ezithile zezinhlelo ezahlukahlukene zokuxhumana. Uhla lwethu lwe-RF Front-End Products luqinisekisa ukusebenza okwenziwe kahle kwezicelo ekuxhumaneni ngocingo, i-aerospace, ezokuvikela, nokuningi.
Ukugcina
I-RF Front-End iyingxenye ebalulekile yanoma yiluphi uhlelo lokuxhumana, iqinisekisa ukudluliswa kwesiginali okusebenzayo nokwamukela ngenkathi kunciphisa ukuphazanyiswa. Ngentuthuko kwezobuchwepheshe kanye nezimfuno ezikhulayo zokusebenza okuphezulu, ukubaluleka kwezixazululo zekhwalithi ephezulu ye-RF Front-End kuyaqhubeka ukukhuphuka, kubenze isakhi esibucayi kumanethiwekhi wanamuhla we-wireless.
