Qhov no yog vim tias 5G cov khoom siv siv ntau qhov sib txawv ntau zaus kom ua tiav cov ntaub ntawv xa mus ceev, ua rau qhov kev thov thiab qhov nyuaj ntawm 5G RF pem hauv ntej-kawg modules ob npaug, thiab qhov ceev tsis tau xav txog.
Complexity tsav txoj kev loj hlob sai ntawm RF module lag luam
Cov qauv no tau lees paub los ntawm cov ntaub ntawv ntawm ntau lub koom haum tsom xam.Raws li Gartner qhov kev kwv yees, RF pem hauv ntej-kawg lag luam yuav ncav cuag US $ 21 nphom los ntawm 2026, nrog CAGR ntawm 8.3% los ntawm 2019 txog 2026;Yole qhov kev kwv yees yog qhov zoo dua.Lawv kwv yees tias tag nrho cov lag luam loj ntawm RF pem hauv ntej-kawg yuav ncav cuag 25.8 billion US dollars nyob rau hauv 2025. Ntawm lawv, RF module lag luam yuav ncav cuag 17.7 billion US dollars, accounting rau 68% ntawm tag nrho cov lag luam loj, nrog ib tug compound txhua xyoo kev loj hlob. tus nqi ntawm 8%;Qhov ntsuas ntawm cov khoom siv sib cais yog US $ 8.1 billion, suav txog 32% ntawm tag nrho cov lag luam nplai, nrog CAGR ntawm 9%.
Piv nrog rau cov chips multimode thaum ntxov ntawm 4G, peb tuaj yeem nkag siab qhov kev hloov pauv no.
Lub sijhawm ntawd, 4G multimode nti tsuas suav nrog 16 zaus bands, uas tau nce mus rau 49 tom qab nkag mus rau lub sijhawm ntawm ntiaj teb tag nrho-netcom, thiab tus naj npawb ntawm 3GPP tau nce mus rau 71 tom qab ntxiv 600MHz zaus band.Yog hais tias 5G millimeter yoj zaus band raug txiav txim siab dua, tus naj npawb ntawm cov zaus bands yuav nce ntau dua;Tib yam muaj tseeb rau cov khoom siv sib xyaw ua ke - thaum kev sib xyaw ua ke ntawm cov cab kuj nyuam qhuav pib xyoo 2015, muaj txog 200 qhov sib xyaw ua ke;Xyoo 2017, muaj kev thov ntau dua 1000 zaus bands;Nyob rau theem pib ntawm kev txhim kho 5G, tus naj npawb ntawm cov zaus sib txuas ua ke tau tshaj 10000.
Tab sis nws tsis yog tsuas yog tus naj npawb ntawm cov khoom siv uas tau hloov pauv.Hauv kev siv tswv yim, noj 5G millimeter yoj qhov system ua haujlwm hauv 28GHz, 39GHz lossis 60GHz zaus band raws li piv txwv, ib qho ntawm cov teeb meem loj tshaj plaws uas nws ntsib yog yuav ua li cas kov yeej cov yam ntxwv tsis zoo ntawm kev nthuav tawm.Tsis tas li ntawd, kev hloov pauv cov ntaub ntawv dav dav, kev ua haujlwm siab hloov pauv, kev siv hluav taws xob zoo piv rau cov khoom siv hluav taws xob tsim, kev ntim khoom siab heev, kev sim OTA, kav hlau txais xov calibration, thiab lwm yam., tag nrho cov tsim teeb meem tsim los ntawm millimeter yoj band 5G nkag system.Nws tuaj yeem kwv yees tias tsis muaj kev txhim kho RF zoo heev, nws tsis tuaj yeem tsim 5G terminals nrog kev sib txuas zoo heev thiab lub neej ruaj khov.
Vim li cas RF pem hauv ntej-kawg thiaj li nyuaj?
RF pem hauv ntej-kawg pib los ntawm tus kav hlau txais xov, dhau los ntawm RF transceiver thiab xaus ntawm lub modem.Tsis tas li ntawd, muaj ntau yam RF technologies siv ntawm cov kav hlau txais xov thiab modems.Daim duab hauv qab no qhia txog cov khoom ntawm RF pem hauv ntej-kawg.Rau cov neeg muag khoom ntawm cov khoom no, 5G muab lub sijhawm kub los nthuav kev lag luam, vim tias kev loj hlob ntawm RF cov ntsiab lus hauv ntej-kawg yog proportional rau qhov nce ntawm RF complexity.
Ib qho kev muaj tiag uas tsis tuaj yeem tsis quav ntsej yog tias RF pem hauv ntej-kawg tsim tsis tuaj yeem nthuav dav synchronously nrog qhov kev thov nce rau mobile wireless.Vim hais tias spectrum yog ib qho tsis tshua muaj peev txheej, feem ntau cov xov tooj ntawm tes niaj hnub no tsis tuaj yeem ua tau raws li qhov xav tau ntawm 5G, yog li cov neeg tsim qauv RF yuav tsum tau ua tiav kev txhawb nqa RF ua ke tsis tau pom dua ntawm cov neeg siv khoom siv thiab tsim cov qauv siv xov tooj ntawm tes nrog kev sib raug zoo tshaj plaws.
Los ntawm Sub-6GHz mus rau millimeter nthwv dej, txhua qhov muaj spectrum yuav tsum tau siv thiab txhawb nqa hauv qhov tseeb RF thiab kav hlau txais xov tsim.Vim qhov tsis sib xws ntawm cov peev txheej spectrum, ob qho tib si FDD thiab TDD yuav tsum tau muab tso ua ke rau hauv RF pem hauv ntej-kawg tsim.Tsis tas li ntawd, cov neeg nqa khoom sib sau ua ke nce qhov bandwidth ntawm lub raj xa dej virtual los ntawm kev khi cov spectrum ntawm ntau zaus, uas kuj ua rau kom cov kev xav tau thiab qhov nyuaj ntawm RF pem hauv ntej kawg.
