I-1) i-RF front-end yinxalenye ephambili yenkqubo yonxibelelwano
Isiphelo sangaphambili serediyo inomsebenzi wokufumana nokusasaza iisiginali zerediyo. Ukusebenza kwayo kunye nomgangatho zizinto eziphambili ezibonisa amandla omqondiso, isantya soxhulumaniso lwenethiwekhi, i-bandwidth yesignali, umgangatho wonxibelelwano, kunye nezinye izibonakaliso zonxibelelwano.
Ngokubanzi, onke amacandelo aphakathi kwe-eriyali kunye ne-RF transceiver abizwa ngokudibeneyo njenge-RF front-end. Iimodyuli ze-RF zangaphambili ezimelwe yi-Wi-Fi, iBluetooth, iselula, i-NFC, i-GPS, njl.
2） Ukuhlelwa kunye nolwahlulo olusebenzayo lweRF front-end
Kukho iintlobo ngeentlobo ze-RF front-end. Ngokwefomu, zinokwahlulwa zibe zizixhobo ezidityanisiweyo kunye neemodyuli zeRF. Emva koko, izixhobo ezidityanisiweyo zinokwahlulwa zibe ngamacandelo ahlukeneyo asebenzayo ngokwemisebenzi yazo, kwaye iimodyuli zeRF zinokwahlulwa zibe ziindlela ezisezantsi, eziphakathi, neziphezulu zokudityaniswa ngokwenqanaba lokudityaniswa. iqela. Ukongeza, ngokwendlela yokuhambisa umqondiso, isiphelo sangaphambili seRF sinokuhlulwa sibe yindlela yokuhambisa kunye nendlela yokufumana.
Ukusuka kulwahlulo olusebenzayo lwezixhobo ezidityanisiweyo, lwahlulwe ikakhulu kwi-amplifier yamandla (PA),i-duplexer (iDuplexer kunye neDiplexer), iswitsha kanomathotholo (Tshintsha),isihluzo (Hluza)kunye nesandisi-lizwi esisezantsi (LNA), njl., kunye ne-baseband chip yenza inkqubo epheleleyo yerediyo.
I-amplifier yamandla (i-PA) inokwandisa i-radio frequency signal ye-channel yokudlulisa, kunye ne-duplexer (i-Duplexer kunye ne-Diplexer) inokuhlukanisa ukuhambisa kunye nokufumana iimpawu ukuze izixhobo ezabelana nge-eriyali efanayo zisebenze ngokuqhelekileyo; iswitsha yerediyo yerediyo (Tshintsha) inokuqonda ulwamkelo lwesiginali yerediyo kunye noThutho lokutshintsha, ukutshintsha phakathi kweebhendi zamaza ezahlukeneyo; Izihluzi zinokugcina imiqondiso kwiibhendi ezithile zefrikhwensi kwaye zihluze imiqondiso ngaphandle kweebhendi ezithile zamaza; Izandisi zomsindo ophantsi (LNA) zinokwandisa iimpawu ezincinci kwindlela yokufumana.
Ukwahlula iimodyuli eziphantsi, eziphakathi, neziphezulu zokudityaniswa ngokwenqanaba lokudityaniswa kweemodyuli zerediyo. Phakathi kwazo, iimodyuli ezinokuhlanganiswa okuphantsi ziquka i-ASM, i-FEM, njl., kunye neemodyuli ezinokuhlanganiswa okuphakathi ziquka i-Div FEM, i-FEMID, i-PAiD, i-SMMB PA, i-MMMB PA, i-RX Module, kunye ne-TX Module, njl., iimodyuli ezinezinga eliphezulu ukuhlanganiswa kubandakanya i-PAMiD kunye ne-LNA Div FEM.
Indlela yokudlulisa umqondiso inokwahlulwa ibe yindlela yokudlulisa kunye nendlela yokufumana. Indlela yokudlulisa ikakhulu ibandakanya izandisi zamandla kunye nezihluzi, kwaye indlela yokufumana ikakhulu ibandakanya ukutshintshwa kwamaza kanomathotholo, ii-amplifiers ezisezantsi, kunye nezihluzi.
