1) RF kutsogolo-kumapeto ndiye chigawo chachikulu cha njira yolumikizirana
Kumapeto kwa mawayilesi akutsogolo kumakhala ndi ntchito yolandila ndi kutumiza ma frequency a wailesi. Kuchita kwake ndi khalidwe lake ndilo zinthu zazikulu zomwe zimatsimikizira mphamvu ya chizindikiro, kuthamanga kwa intaneti, bandwidth ya chizindikiro, khalidwe la kulankhulana, ndi zizindikiro zina zoyankhulirana.
Nthawi zambiri, zigawo zonse zomwe zili pakati pa mlongoti ndi transceiver ya RF pamodzi zimatchedwa RF front-end. Ma module akutsogolo a RF omwe amaimiridwa ndi Wi-Fi, Bluetooth, ma cellular, NFC, GPS, ndi zina zambiri amatha kuzindikira maukonde, kusamutsa mafayilo, kulumikizana, kusuntha makadi, kuyimitsa, ndi ntchito zina.
2） Gulu ndi magawo ogwira ntchito a RF kutsogolo-kumapeto
Pali mitundu yosiyanasiyana ya ma RF front-end. Malinga ndi mawonekedwe, amatha kugawidwa m'zida zapadera ndi ma module a RF. Kenako, zida za discrete zitha kugawidwa m'zigawo zosiyanasiyana zogwirira ntchito molingana ndi ntchito zawo, ndipo ma module a RF amatha kugawidwa m'njira zotsika, zapakatikati, komanso zophatikizika kwambiri malinga ndi kuchuluka kwa kuphatikiza. gulu. Kuphatikiza apo, molingana ndi njira yotumizira ma siginecha, kutsogolo kwa RF kumatha kugawidwa kukhala njira yopatsira ndi njira yolandirira.
Kuchokera pagawo logwira ntchito la zida za discrete, zimagawidwa makamaka kukhala amplifier yamagetsi (PA),duplexer (Duplexer ndi Diplexer), switch ya radio frequency (Sinthani),sefa (sefa)ndi low noise amplifier (LNA), etc., kuphatikiza baseband chip imapanga dongosolo lathunthu lawayilesi.
Mphamvu ya amplifier (PA) imatha kukulitsa ma frequency a wailesi ya njira yotumizira, ndipo duplexer (Duplexer ndi Diplexer) imatha kudzipatula kutumizira ndi kulandira ma siginecha kuti zida zogawana mlongoti womwewo zitha kugwira ntchito moyenera; switch ya ma radio frequency (Sinthani) imatha kuzindikira kulandila kwa siginecha yawayilesi ndi Kutumiza kusintha, kusinthana pakati pa magulu osiyanasiyana; Zosefera zimatha kusunga ma siginecha m'mabandi apadera ndikusefa ma siginolo kunja kwa bandi yapadera; Zida zochepetsera phokoso (LNA) zimatha kukulitsa zizindikiro zazing'ono panjira yolandira.
Gawani ma module otsika, apakati, ndi apamwamba ophatikizana molingana ndi mulingo wophatikizira wa ma frequency module a radio. Mwa iwo, ma module okhala ndi kuphatikizika pang'ono akuphatikizapo ASM, FEM, etc., ndipo ma module okhala ndi kuphatikiza kwapakatikati akuphatikizapo Div FEM, FEMID, PAiD, SMMB PA, MMMB PA, RX Module, ndi TX Module, ndi zina zambiri, ma module okhala ndi digiri yayikulu ya kuphatikiza kuphatikiza PAMiD ndi LNA Div FEM.
Njira yotumizira chizindikiro imatha kugawidwa m'njira yotumizira ndi njira yolandirira. Njira yopatsirana makamaka imaphatikizapo zokulitsa mphamvu ndi zosefera, ndipo njira yolandirira makamaka imaphatikizapo masiwichi a wailesi, zokulitsa phokoso lotsika, ndi zosefera.
