1) RF e ka pele-pele ke karolo ea mantlha ea sistimi ea puisano
Karolo e ka pele ea maqhubu a radio e na le mosebetsi oa ho amohela le ho fetisa matshwao a maqhubu a radio.Ts'ebetso ea eona le boleng ba eona ke lintlha tsa bohlokoa tse khethollang matla a pontšo, lebelo la khokahanyo ea marang-rang, bandwidth ea matšoao, boleng ba puisano, le matšoao a mang a puisano.
Ka kakaretso, likarolo tsohle tse lipakeng tsa lenaka le transceiver ea RF ka kakaretso li bitsoa pheletso ea RF.Li-module tsa RF tse emeloa ke Wi-Fi, Bluetooth, cellular, NFC, GPS, joalo-joalo li ka hlokomela marang-rang, phetisetso ea lifaele, puisano, ho swiping karete, ho beha maemo le mesebetsi e meng.
2) Classification le karohano e sebetsang ea RF front-end
Ho na le mefuta e fapaneng ea li-frontend tsa RF.Ho latela foromo, li ka aroloa ka lisebelisoa tse fapaneng le li-module tsa RF.Ebe, lisebelisoa tsa discrete li ka aroloa ka likarolo tse fapaneng tsa ts'ebetso ho latela mesebetsi ea tsona, 'me li-module tsa RF li ka aroloa ka mekhoa e tlase, e mahareng le e phahameng ea kopanyo ho latela tekanyo ea kopanyo.sehlopha.Ntle le moo, ho latela tsela ea phetiso ea lets'oao, pheletso ea pele ea RF e ka aroloa ka tsela e fetisang le tsela ea ho amohela.
Ho tloha karohanong e sebetsang ea lisebelisoa tsa discrete, e arotsoe haholo ka amplifier ea matla (PA),duplexer (Duplexer le Diplexer), switch frequency radio (Switch),sefe (Sefe)le amplifier ea lerata le tlase (LNA), joalo-joalo, hammoho le baseband chip e theha sistimi e felletseng ea maqhubu a radio.
Matla a amplifier (PA) a ka holisa lets'oao la maqhubu a seea-le-moea sa mocha o fetisang, 'me duplexer (Duplexer le Diplexer) e ka arola matšoao a ho fetisa le ho amohela e le hore lisebelisoa tse arolelanang antenna e tšoanang li ka sebetsa ka mokhoa o tloaelehileng;switch frequency radio (Switch) e khona ho lemoha kamohelo ea leqhubu la radio le Transmitting switching, ho chencha lipakeng tsa mefuta e fapaneng ea maqhubu;Lisefe li ka boloka mats'oao lihlopheng tse ikhethileng tsa maqhubu le ho sefa matshwao ka ntle ho lihlopha tse ikhethileng tsa maqhubu;Li-amplifiers tse tlase tsa lerata (LNA) li ka holisa matšoao a manyane tseleng e amohelang.
Arola li-module tsa ho kopanya tse tlaase, tse mahareng le tse phahameng ho latela boemo ba ho kopanya li-module tsa maqhubu a seea-le-moea.Har'a tsona, li-module tse nang le kopanyo e tlase li kenyelletsa ASM, FEM, joalo-joalo, 'me li-module tse nang le kopanyo e mahareng li kenyelletsa Div FEM, FEMID, PAiD, SMMB PA, MMMB PA, RX Module, le TX Module, joalo-joalo, li-module tse nang le tekanyo e phahameng ea kopanyo e kenyelletsa PAMiD le LNA Div FEM.
Tsela ea phetisetso ea lets'oao e ka aroloa ka tsela e fetisang le tsela ea ho amohela.Tsela ea phetisetso haholo-holo e kenyelletsa liamplifiers le li-filters, 'me tsela e amohelang haholo e kenyelletsa li-switches tsa radio frequency, li-amplifiers tse tlase le li-filters.
