Litsamaisong tsa puisano tse se nang mohala, hangata ho na le likarolo tse 'ne: antenna, radio frequency (RF) front-end, RF transceiver, le baseband signal processor.
Ka ho fihla ha mehla ea 5G, tlhoko le boleng ba li-antenna le li-front-ends tsa RF li eketsehile ka potlako. RF front-end ke karolo ea motheo e fetolang matšoao a dijithale hore e be matšoao a RF a se nang mohala, 'me hape ke karolo ea mantlha ea litsamaiso tsa puisano tse se nang mohala.
Ka tshebetso, karolo e ka pele ya RF e ka arolwa ka lehlakore la phetiso (Tx) le lehlakore la kamohelo (Rx).
● Sefa: E kgetha maqhubu a itseng mme e sefa matshwao a tshitiso
● Duplexer/Multiplexer: E arola matšoao a fetiselitsoeng/a amohetsoeng
● Seholisa-matla sa Matla (PA): Se eketsa matšoao a RF bakeng sa phetiso
● Seholisa-lerata se Tlase (LNA): Se eketsa matšoao a amohetsoeng ha se ntse se fokotsa tlhahiso ea lerata
● Switch ea RF: E laola potoloho ho bula/ho tima ho nolofatsa ho fetola matshwao
● Sehokelo: Ho bapisa impedance bakeng sa antenna
● Likarolo tse ling tsa RF tse ka pele
Sesupa-tsela sa Enfelopo (ET) se sebelisetsoa ho ntlafatsa bokgoni ba amplifier ea matla bakeng sa matšoao a nang le likarolelano tse phahameng tsa matla a tlhōrō ho ea ho a tloaelehileng ka ho nolofalletsa liphetho tse matlafalitsoeng tsa matla a feto-fetohang.
Ha ho bapisoa le mekhoa e tloaelehileng ea ho latela matla, ho latela enfelopo ho lumella motlakase oa amplifier ea motlakase ho latela enfelopo ea lets'oao la ho kenya, ho ntlafatsa ts'ebetso ea matla ea amplifier ea matla a RF.
Moamoheli oa RF o fetola matšoao a RF ka antenna ka likarolo tse kang li-filter, li-LNA, le li-converter tsa analog-to-digital (ADCs) ho fetola le ho fokotsa lets'oao, qetellong a theha lets'oao la baseband e le tlhahiso.
Concept Microwave ke moetsi oa litsebi oa likarolo tsa 5G RF Chaena, ho kenyeletsoa le sefe sa RF lowpass, sefe sa highpass, sefe sa bandpass, sefe sa notch/band stop, duplexer, Power divider le directional coupler. Kaofela ha tsona li ka fetoloa ho latela litlhoko tsa hau.
