Indima ye-RF front-end kwiinkqubo zonxibelelwano

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 aquke ahlulwe abe yi-amplifier yamandla (PA), i-duplexer (i-Duplexer kunye ne-Diplexer), i-radio frequency switch (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, ngokusekelwe kwinqanaba lokudibanisa, ukusuka kwiimodyuli eziphantsi zokudibanisa (ezifana ne-ASM, i-FEM) ukuya kwiimodyuli zokudibanisa okuphakathi (njenge-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.
