Zeziphi Izinto Eziqukiweyo Kwi-Radio Frequency Front-end

Kwiinkqubo zonxibelelwano ezingenazingcingo, zihlala zinezinto ezine: i-antenna, i-radio frequency (RF) front-end, i-RF transceiver, kunye ne-baseband signal processor.

Ngokufika kwexesha le-5G, imfuno kunye nexabiso lee-antenna kunye nee-RF front-ends zinyuke ngokukhawuleza. I-RF front-end yeyona nto iphambili eguqula imiqondiso yedijithali ibe yimiqondiso ye-RF engenazingcingo, kwaye ikwayeyona nto iphambili kwiinkqubo zonxibelelwano ezingenazingcingo.

Ngokusebenzayo, i-RF front-end inokwahlulwa ibe licala lokudlulisa (Tx) kunye necala lokwamkela (Rx).

● Isihluzi: Ikhetha amaza athile kwaye ihluze imiqondiso yokuphazamiseka

● I-Duplexer/i-Multiplexer: Ihlukanisa imiqondiso edluliselweyo/efunyenweyo

● Isandisi-mandla (PA): Ikhulisa imiqondiso yeRF yokudlulisela

● Isandisi-sandi esiphantsi (i-LNA): Sikhulisa imiqondiso efunyenweyo ngelixa sinciphisa ukungeniswa kwengxolo

● Iswitshi ye-RF: Ilawula isekethe ivuliwe/icinyiwe ukuze kube lula ukutshintsha isignali

● I-Tuner: Ukulinganisa i-impedance ye-antenna

● Ezinye izinto ze-RF front-end

I-Envelope Tracker (ET) isetyenziselwa ukuphucula ukusebenza kakuhle kwe-power amplifier kwiisignali ezinemilinganiselo yamandla ephezulu ukusuka kwi-peak ukuya kwi-avareji ngokuvumela iziphumo eziphuculweyo zamandla aguquguqukayo.

Xa kuthelekiswa neendlela zokulandelela amandla eziqhelekileyo, ukulandelela ngemvulophu kuvumela i-voltage yombane ye-amplifier ukuba ilandele i-envelope yesignali yokufaka, nto leyo ephucula ukusebenza kakuhle kwamandla e-RF power amplifier.

I-RF Receiver eguqulayo ifumene imiqondiso ye-RF nge-antenna ngokusebenzisa izinto ezifana nezihluzi, ii-LNA, kunye nee-analog-to-digital converters (ii-ADC) ukuze iguqule kwaye iguqule isignali, ekugqibeleni yenze isignali ye-baseband njengesiphumo.

I-Concept Microwave ngumvelisi ochwephesha wezixhobo ze-5G RF eTshayina, kuquka isihluzo se-RF lowpass, isihluzo se-highpass, isihluzo se-bandpass, isihluzo se-notch/i-band stop, i-duplexer, i-Power divider kunye ne-directional coupler. Zonke zingenziwa ngokwezifiso ngokweemfuno zakho.
