Sistimi ea puisano e se nang mohala ka kakaretso e kenyelletsa likarolo tse 'ne: antenna, radio frequency front-end, radio frequency transceiver module, le baseband signal processor.
Ka ho fihla ha mehla ea 5G, tlhoko le boleng ba li-antenna le li-radio frequency front-ends li ntse li phahama ka potlako.Maqhubu a maqhubu a seea-le-moea ke karolo ea mantlha e fetolang matshwao a dijithale ho ba matshwao a maqhubu a radio a waelese hape ke karolo ya mantlha ya mokgwa wa puisano wa waelese.
Ho latela ts'ebetso, sebaka sa pele sa radio frequency se ka aroloa ka pheletsong ea phetiso Tx le pheletsong e amohelang Rx.
Ho latela lisebelisoa tse fapaneng, pheletso ea pele ea RF e ka aroloa ka li-amplifiers tsa matla (amplification ea RF qetellong ea transmitter),lifela (sefa sa lets'oao ho transmitter le moamoheli qetellong),liamplifier tse nang le lerata le tlase (matlafatso a mats'oao qetellong ea moamoheli, phokotso ea lerata), li-switches (ho fetoha lipakeng tsa liteishene tse fapaneng),Duplexer(khetho ea mats'oao, ho bapisa sefahla), tuner (ho bapisa sekanale sa li-antenna) joalo-joalo.
Sefe: maqhubu a khethehileng a heke le matšoao a tšitiso ea sefe
The sefepike sesebelisoa sa bohlokoa ka ho fetisisa sa discrete pheletsong ea pele ea RF.E lumella likarolo tse itseng tsa maqhubu a lets'oao hore li fete le ho fokotsa haholo likarolo tse ling tsa maqhubu, ka ho etsa joalo e ntlafatse matla a lets'oao a khahlanong le tšitiso le karo-karolelano ea lerata.
Diplexer/Multiplexer: Ho itšehla thajana ho fetisa / ho amohela lipontšo
The duplexer, e tsejoang hape e le lenaka duplexer, e na le lihlopha tse peli tsa li-band-stop filters tse nang le maqhubu a fapaneng.
The duplexere sebelisa tšebetso ea karohano ea maqhubu a sefene se phahameng, se tlase kapa se fetisang sehlopha ho lumella antenna e tšoanang kapa mohala oa phetisetso ho sebelisa litsela tse peli tsa mats'oao, ka hona e nolofalletsa lenakana le tšoanang ho amohela le ho fetisa mats'oao a maqhubu a mabeli a fapaneng.
Amplifier ea lerata e tlase(LNA): e holisa lets'oao le amohetsoeng mme e fokotsa kenyelletso ea lerata
The amplifier ea lerata le tlaseke amplifier e nang le palo e nyane haholo ea lerata.Mosebetsi oa eona ke ho holisa lets'oao le fokolang la radio frequency le amohetsoeng ke lenakana le ho fokotsa ho kenya lerata.LNA e ka ntlafatsa ka nepo kutloisiso ea moamoheli, ka hona e eketsa sebaka sa phetisetso ea transceiver.
Ake moetsi ea hloahloa le ea tsoetseng pele oa likarolo tsa RF & Microwave, CHengdu Jingxin Microwave Technology Co., Ltd e sebetsa ka thata ho rala le ho etsa likarolo tse ngata tse fapaneng tse tloaelehileng le tse entsoeng ka mokhoa o ikhethileng tse nang le ts'ebetso e etelletseng pele ho tloha ho DC ho isa ho 110GHz.
