Yiziphi izingxenye ezifakwe ku-RF front-end?

Amasistimu okuxhumana okungenazintambo ngokuvamile ahlanganisa izingxenye ezine: uthi, isiphetho sefrikhwensi yomsakazo, imojula ye-transceiver frequency radio, kanye neprosesa yesiginali ye-baseband.

Ngokufika kwenkathi ye-5G, isidingo nenani lama-antenna kanye nama-front-end frequency omsakazo akhuphuka ngokushesha.I-front-end yefrikhwensi yomsakazo iyingxenye eyisisekelo eguqula amasignali edijithali abe amasignali amafrikhwensi omsakazo angenawaya futhi iyingxenye eyinhloko yohlelo lokuxhumana okungenazintambo.

Ngokohlelo, isiphetho sefrikhwensi yomsakazo ngaphambili singahlukaniswa sibe isiphetho sokudlulisa i-Tx nesiphetho esamukelayo esingu-Rx.

Ngokusho kwamadivayisi ahlukene, i-RF front-end ingahlukaniswa ngama-amplifiers amandla (ukukhulisa isignali ye-RF ekugcineni kwe-transmitter),izihlungi (ukuhlunga isignali ekugcineni komthumeli nomamukeli),ama-amplifiers anomsindo ophansi (ukukhulisa isignali ekugcineni kowamukelayo, ukuncishiswa komsindo), amaswishi (ukushintsha phakathi kwamashaneli ahlukene),I-Duplexer(ukukhethwa kwesignali, ukufaniswa kwesihlungi), ishuna (ukufaniswa kokuphazamiseka kweshaneli yesignali ye-antenna), njll.

Hlunga: isango amafrikhwensi athile kanye nezimpawu zokuphazamiseka kwesihlungi

I isihlungiiyidivayisi ebaluleke kakhulu ehlukanisayo ekugcineni kwe-RF.Ivumela izingxenye ezithile zefrikhwensi kusignali ukuthi zidlule futhi inciphise kakhulu ezinye izingxenye zefrikhwensi, ngaleyo ndlela ithuthukise isignali yokulwa nokuphazamiseka kanye nesilinganiso sesignali-kuya-nomsindo.

I-Diplexer/Multiplexer: Ukuhlukaniswa kokudlulisa/ukwamukela amasignali

I i-duplexer, eyaziwa nangokuthi i-antenna i-duplexer, iqukethe amasethi amabili ezihlungi ze-band-stop ezinamafrikhwensi ahlukene.

I i-duplexerisebenzisa umsebenzi wokuhlukanisa ama-frequency wesihlungi se-high-pass, low-pass noma i-band-pass ukuze ivumele uthi olufanayo noma ulayini wokudlulisa ukuthi usebenzise izindlela ezimbili zesignali, ngaleyo ndlela yenze ukuthi uthi olufanayo lwamukele futhi ludlulise amasignali amafrikhwensi amabili ahlukene.

Isikhulisi somsindo ophansi(I-LNA): ikhulisa isignali eyamukelwe futhi inciphise ukwethulwa komsindo

I i-amplifier yomsindo ophansiiyi-amplifier enomsindo omncane kakhulu.Umsebenzi wayo ukukhulisa isignali yefrikhwensi yomsakazo ebuthaka etholwe uthingo futhi kuncishiswe ukwethulwa komsindo.I-LNA ingathuthukisa ngempumelelo ukuzwela kokwamukela komamukeli, ngaleyo ndlela ikhulise ibanga lokudlulisela le-transceiver.
