Kwiinkqubo zonxibelelwano zanamhlanje, i-Radio Frequency (RF) i-front-end idlala indima ebalulekileyo ekwenzeni unxibelelwano olungenazingcingo olusebenzayo. Ibekwe phakathi kwe-eriyali kunye ne-digital baseband, isiphelo se-RF sangaphambili sinoxanduva lokusetyenzwa kwemiqondiso engenayo nephumayo, iyenza ibe yinxalenye ebalulekileyo kwizixhobo ezisusela kwii-smartphones ukuya kwiisathelayithi.
Yintoni i-RF Front-End?
I-RF front-end iqulathe amacandelo ahlukeneyo aphatha ulwamkelo nokuhanjiswa komqondiso. Izinto eziphambili ziquka ii-amplifiers zamandla (PA), i-low-noise amplifiers (LNA), izihluzi, kunye nokutshintsha. La macandelo asebenza kunye ukuqinisekisa ukuba iimpawu zihanjiswa ngamandla afunwayo kunye nokucaca, ngelixa kuncitshiswa ukuphazamiseka kunye nengxolo.
Ngokuqhelekileyo, onke amacandelo phakathi kwe-eriyali kunye ne-RF transceiver zibizwa ngokuba yi-RF front-end, eqinisekisa ukuhanjiswa komqondiso okungenazingcingo.
2) Ukuhlelwa kunye noMsebenzi we-RF Front-End
I-RF front-end inokuhlelwa ngokweendidi ezimbini eziphambili ngokusekwe kwifomu yayo: amacandelo ahlukeneyo kunye neemodyuli zeRF. Amacandelo ahlukeneyo ahlelwa ngokusekwe kumsebenzi wawo, ngelixa iimodyuli zeRF zahlulwe zaba ngamanqanaba asezantsi, aphakathi, kunye naphezulu okudibanisa. Ukongeza, ngokuxhomekeke kwindlela yothumelo lwesignali, isiphelo se-RF sangaphambili sahlulwe ngokweendlela zothumelo kunye nolwamkelo.
Ukusuka kulwahlulo olusebenzayo lwezixhobo ezidityanisiweyo, amacandelo aphambili e-RF yangaphambili-ekupheleni aqukiwe ahlulwe abe yi-amplifier yamandla (PA), i-duplexer (iDuplexer kunye neDiplexer), iswitshi yerediyo (Switch), isihluzi (Isihluzi) kunye nesandisi sesandi esisezantsi (LNA), njl.,. Ezi zixhobo, kunye ne-baseband chip, zenza inkqubo yeRF epheleleyo.
I-Amplifaya zamandla (PA): Yomeleza umqondiso ohanjiswayo.
I-Duplexers: Ugqithiso olwahlukileyo kunye neempawu zokwamkela, ukuvumela izixhobo zabelane nge-eriyali efanayo ngokufanelekileyo.
Iswitshi yamaza kanomathotholo (Tshintsha): Yenza ukutshintsha phakathi kosasazo nolwamkelo okanye phakathi kweebhendi zamaza ohlukeneyo.
Izihluzi: Hlunga iifrikhwensi ezingafunwayo kwaye ugcine uphawu olufunekayo.
I-Low-Noise Amplifiers (LNA): Ukwandisa iimpawu ezibuthathaka kwindlela yokufumana.
Iimodyuli ze-RF, ezisekelwe kwinqanaba lokudibanisa, ukusuka kwiimodyuli eziphantsi zokudibanisa (ezifana ne-ASM, i-FEM) ukuya kwiimodyuli zokudibanisa okuphakathi (ezifana ne-Div FEM, i-FEMID, i-PAiD), kunye neemodyuli eziphezulu zokudibanisa (ezifana ne-PAMiD, i-LNA Div FEM ). Uhlobo ngalunye lwemodyuli yenzelwe ukuhlangabezana neemfuno ezahlukeneyo zesicelo.
Ukubaluleka kwiiNkqubo zoNxibelelwano
Umphambili weRF sisixhobo esiphambili sonxibelelwano olungenazingcingo olusebenzayo. Imisela ukusebenza kwenkqubo iyonke ngokwamandla omqondiso, umgangatho, kunye ne-bandwidth. Kuthungelwano lweselula, umzekelo, i-RF front-end iqinisekisa unxibelelwano olucacileyo phakathi kwesixhobo kunye nesitishi esisisiseko, ichaphazela ngokuthe ngqo umgangatho wefowuni, isantya sedatha, kunye noluhlu lokhuseleko.
