Litsamaisong tsa sejoale-joale tsa puisano, seea-le-moea sa Radio Frequency (RF) se bapala karolo ea bohlokoa ho nolofatseng puisano e sebetsang ea waelese. E behiloe lipakeng tsa antenna le baseband ea dijithale, RF e ka pele-pele e ikarabella bakeng sa ho sebetsana le matšoao a kenang le a tsoang, e leng se etsang hore e be karolo ea bohlokoa ho lisebelisoa ho tloha ho li-smartphone ho isa ho lisathelaete.
RF Front-End ke eng?
RF front-end e na le likarolo tse fapaneng tse sebetsanang le ho amohela le ho fetisoa ha lets'oao. Lintlha tsa bohlokoa li kenyelletsa liamplifiers tsa motlakase (PA), liamplifiers tsa lerata le tlase (LNA), li-filters le li-switches. Likarolo tsena li sebetsa 'moho ho netefatsa hore matšoao a fetisoa ka matla a lakatsehang le ho hlaka, ha a ntse a fokotsa tšitiso le lerata.
Ka tloaelo, likarolo tsohle tse lipakeng tsa antenna le transceiver ea RF li bitsoa RF front-end, ho netefatsa phetisetso e ntle ea leqhubu la waelese.
2) Sehlopha le Mosebetsi oa RF Front-End
Karolo e ka pele ea RF e ka aroloa ka mefuta e 'meli e meholo ho latela sebopeho sa eona: likarolo tse ikhethang le li-module tsa RF. Likarolo tse ikhethileng li aroloa ho latela ts'ebetso ea tsona, ha li-module tsa RF li arotsoe ka maemo a tlase, a mahareng le a holimo a kopanyo. Ho ekelletsa moo, ho ipapisitse le tsela ea phetiso ea lets'oao, karolo e ka pele ea RF e arotsoe ka litsela tsa phetiso le ho amohela.
Ho tloha karolong e sebetsang ea lisebelisoa tsa discrete, likarolo tsa bohlokoa tsa RF front-end li kenyelletsa li arotsoe ka amplifier ea matla (PA), duplexer (Duplexer le Diplexer), switch frequency radio (Switch), filthara (Filter) le low noise amplifier (LNA), joalo-joalo,. Likarolo tsena, hammoho le chip ea baseband, li theha sistimi e felletseng ea RF.
Matla a Amplifiers (PA): Matlafatsa lets'oao le fetisoang.
Li-Duplexers: Lipontšo tse arohaneng tsa phetisetso le kamohelo, tse lumellang lisebelisoa ho arolelana antenna e tšoanang hantle.
Radio frequency switch (Switch): E nolofalletsa phetoho lipakeng tsa phetiso le kamohelo kapa lipakeng tsa mefuta e fapaneng ea maqhubu.
Lisefe: Sefa maqhubu a sa batleheng ebe u boloka lets'oao le lakatsehang.
Li-Amplifaya tsa Low-Noise (LNA): Holisa matšoao a fokolang tseleng ea ho amohela.
Li-module tsa RF, tse ipapisitseng le boemo ba tsona ba ho kopanya, li tloha ho li-modules tse tlaase-tlaase (tse kang ASM, FEM) ho ea ho li-module tsa ho kopanya tse mahareng (joaloka Div FEM, FEMID, PAiD), le li-module tsa ho kopanya tse phahameng (tse kang PAMiD, LNA Div FEM). ). Mofuta o mong le o mong oa mojule o etselitsoe ho fihlela litlhoko tse fapaneng tsa ts'ebeliso.
Bohlokoa Litsamaisong tsa Lipuisano
Qetello ea pele ea RF ke senotlolo sa bohlokoa sa puisano e sebetsang ea waelese. E lekanya ts'ebetso ea kakaretso ea sistimi ho latela matla a lets'oao, boleng le bandwidth. Ka mohlala, marang-rang a cellular, RF front-end e netefatsa puisano e hlakileng pakeng tsa sesebelisoa le setsi sa motheo, e amang ka ho toba boleng ba mohala, lebelo la data, le sebaka sa tšireletso.
