Oku kungenxa yokuba izixhobo ze-5G zisebenzisa iibhendi ezahlukeneyo ze-high-frequency ukufikelela kwi-high-speed data transmission, okukhokelela kwimfuno kunye nobunzima beemodyuli ze-front-end ze-5G RF ziphindwe kabini, kwaye isantya sasingalindelekanga.
Ukuntsonkotha kuqhuba uphuhliso olukhawulezayo lwemarike yemodyuli yeRF
Lo mkhwa uqinisekiswa yidatha yamaziko amaninzi ohlalutyo.Ngokwengqikelelo kaGartner, imakethi ye-RF yangaphambili iya kufikelela kwi-21 yeebhiliyoni zeedola zaseMelika ngo-2026, kunye ne-CAGR ye-8.3% ukusuka ngo-2019 ukuya ku-2026;Uqikelelo lukaYole lunethemba ngakumbi.Baqikelela ukuba ubungakanani bemarike bubonke be-RF front-end buya kufikelela kwi-25.8 billion yeedola zaseMelika ngo-2025. Phakathi kwabo, imodyuli ye-RF imakethi iya kufikelela kwi-17.7 yeebhiliyoni zeedola zaseMelika, ibalelwa kwi-68% yobungakanani bentengiso iyonke, kunye nokukhula okuhlanganisiweyo ngonyaka. umlinganiselo we-8%;Ubungakanani bezixhobo ezidityanisiweyo beziyi-8.1 yeebhiliyoni zeedola zaseMelika, zibalelwa kwi-32% yesikali sentengiso sisonke, kunye ne-CAGR ye-9%.
Xa kuthelekiswa neechips ze-multimode zakuqala ze-4G, sinokuluva olu tshintsho.
Ngelo xesha, i-chip ye-4G ye-multimode ibandakanya kuphela malunga neebhendi ze-16, eziye zenyuka zaya kwi-49 emva kokungena kwixesha le-global all-netcom, kunye nenani le-3GPP lenyuka laya kwi-71 emva kokongeza ibhendi ye-600MHz.Ukuba i-5G millimeter wave frequency band iqwalaselwa kwakhona, inani le-frequency bands liya kwanda ngakumbi;Kukwanjalo nakwitekhnoloji yokuhlanganiswa kwe-carrier - xa i-carrier aggregation isanda kuqaliswa ngo-2015, kwakukho malunga ne-200 indibaniselwano;Kwi-2017, kwakukho imfuno engaphezulu kwe-1000 bands frequency;Kwinqanaba lokuqala lophuhliso lwe-5G, inani lokudibanisa i-frequency band ligqithise i-10000.
Kodwa ayililo kuphela inani lezixhobo ezitshintshileyo.Kwizicelo ezisebenzayo, ukuthatha inkqubo ye-5G millimeter wave esebenza kwi-28GHz, 39GHz okanye 60GHz band frequency njengomzekelo, omnye weyona miqobo inkulu ejongene nayo yindlela yokoyisa iimpawu ezingafunekiyo zokusasaza.Ukongeza, ukuguqulwa kwedatha ye-broadband, ukuguqulwa kwe-spectrum yokusebenza okuphezulu, ubungakanani bokusebenza kwamandla ombane, itekhnoloji yokupakisha ephezulu, uvavanyo lwe-OTA, ukulinganisa i-eriyali, njl.Kunokuqikelelwa ukuba ngaphandle kokuphuculwa kokusebenza kweRF okugqwesileyo, akunakwenzeka ukuyila iitheminali ze-5G ezinonxibelelwano oluhle kakhulu kunye nobomi obude.
Kutheni i-RF front-end inzima kangaka?
Isiphelo se-RF sangaphambili siqala kwi-eriyali, sidlula kwi-RF transceiver kwaye siphele kwimodem.Ukongeza, zininzi iitekhnoloji zeRF ezisetyenziswayo phakathi kwee-eriyali kunye neemodem.Lo mfanekiso ungezantsi ubonisa amacandelo e-RF front-end.Kubaboneleli bala macandelo, i-5G ibonelela ngethuba legolide lokwandisa imarike, kuba ukukhula komxholo we-RF we-front-end kuhambelana nokunyuka kobunzima be-RF.
Inyani engenakuhoywa yeyokuba uyilo lwe-RF-front-end alunakwandiswa ngaxeshanye kunye nemfuno eyandayo yeefowuni eziphathwayo.Ngenxa yokuba i-spectrum sisixhobo esinqongopheleyo, uninzi lweenethiwekhi zeselula namhlanje azikwazi ukuhlangabezana nemfuno elindelekileyo ye-5G, ngoko ke abaqulunqi be-RF kufuneka bafezekise inkxaso engazange ibonwe ngaphambili ye-RF kwizixhobo zabathengi kunye nokwakha uyilo olungenacingo olungenazingcingo ngokuhambelana kakhulu.
Ukusuka kwi-Sub-6GHz ukuya kwi-millimeter wave, yonke i-spectrum ekhoyo kufuneka isetyenziswe kwaye ixhaswe kuyilo lweRF kunye noyilo lwe-eriyali.Ngenxa yokungangqinelani kwezixhobo ze-spectrum, zombini imisebenzi ye-FDD kunye ne-TDD kufuneka zidityaniswe kuyilo lwe-RF yangaphambili.Ukongeza, ukudityaniswa komthwali kwandisa i-bandwidth yombhobho obonakalayo ngokubophelela i-spectrum yeefrikhwensi ezahlukeneyo, okukwanyusa iimfuno kunye nobunzima be-RF front-end.
