Los ntawm 2030, 6G mobile kev sib txuas lus yuav tsum tau ua txoj hauv kev rau kev siv tshiab xws li kev txawj ntse, kev muaj tiag virtual thiab Internet ntawm Yam.Qhov no yuav xav tau kev ua tau zoo dua li 5G mobile qauv tam sim no siv cov kev daws teeb meem tshiab.Raws li xws li, ntawm EuMW 2022, Fraunhofer IAF yuav nthuav tawm lub zog siv hluav taws xob GaN transmitter module tsim ua ke nrog Fraunhofer HHI rau qhov sib thooj 6G zaus ntau dua 70 GHz.Qhov kev ua tau zoo ntawm qhov module no tau lees paub los ntawm Fraunhofer HHI.
Autonomous tsheb, telemedicine, automated factories - tag nrho cov kev siv yav tom ntej hauv kev thauj mus los, kev noj qab haus huv thiab kev lag luam cia siab rau cov ntaub ntawv thiab kev sib txuas lus thev naus laus zis uas dhau mus dhau lub peev xwm ntawm tam sim no thib tsib tiam (5G) kev sib txuas lus xov tooj ntawm tes.Qhov kev cia siab tso tawm ntawm 6G mobile kev sib txuas lus hauv 2030 cog lus tias yuav muab cov kev sib txuas ceev ceev uas tsim nyog rau cov ntaub ntawv ntim uas xav tau yav tom ntej, nrog cov ntaub ntawv tus nqi ntau dua 1 Tbps thiab latency txog 100 µs.
Txij li thaum 2019 raws li ib txoj haujlwm CONFEKT ("6G Kev Sib Txuas Lus Cheeb Tsam").
Cov kws tshawb fawb tau tsim cov qauv sib kis raws li gallium nitride (GaN) fais fab semiconductor, uas thawj zaug tuaj yeem siv ntau zaus ntawm kwv yees li 80 GHz (E-band) thiab 140 GHz (D-band).Lub tswv yim tshiab E-band transmitter module, uas nws qhov kev ua tau zoo tau ua tiav los ntawm Fraunhofer HHI, yuav nthuav tawm rau cov kws tshaj lij pej xeem ntawm European Microwave Week (EuMW) hauv Milan, Ltalis, txij li 25 txog 30 Cuaj hlis 2022.
"Vim qhov kev xav tau siab ntawm kev ua tau zoo thiab kev ua haujlwm zoo, 6G xav tau cov cuab yeej tshiab," piav qhia Dr. Michael Mikulla los ntawm Fraunhofer IAF, uas yog tus tswj hwm txoj haujlwm KONFEKT."Hnub no cov khoom lag luam tseem ceeb tau nce mus txog lawv cov kev txwv.Qhov no siv tshwj xeeb rau cov thev naus laus zis semiconductor, nrog rau kev sib dhos thiab kav hlau txais xov tshuab.Txhawm rau ua tiav cov txiaj ntsig zoo tshaj plaws ntawm cov zis hluav taws xob, bandwidth thiab lub zog ua haujlwm, peb siv GaN-based monolithic integration Microwave Microwave Circuits (MMIC) ntawm peb cov module hloov tam sim no siv silicon circuits.Raws li dav bandgap semiconductor, GaN tuaj yeem ua haujlwm ntawm cov hluav taws xob ntau dua. , muab cov kev poob qis thiab cov khoom sib txuam ntau dua. Tsis tas li ntawd, peb tab tom txav deb ntawm qhov chaw mount thiab cov qauv tsim cov pob khoom tsim los tsim cov qauv qis qis nrog cov waveguides thiab built-in parallel circuits. "
Fraunhofer HHI kuj tseem koom nrog hauv kev ntsuam xyuas ntawm 3D luam tawm waveguides.Ntau cov khoom tau raug tsim, tsim thiab ua haujlwm siv cov txheej txheem xaiv laser melting (SLM), suav nrog cov hluav taws xob sib cais, kav hlau txais xov thiab kav hlau txais xov.Cov txheej txheem tseem tso cai rau kev tsim khoom sai thiab raug nqi ntawm cov khoom uas tsis tuaj yeem tsim los ntawm cov txheej txheem ib txwm muaj, ua rau txoj kev loj hlob ntawm 6G thev naus laus zis.
"Los ntawm cov kev tsim kho thev naus laus zis no, Fraunhofer Institutes IAF thiab HHI tso cai rau lub teb chaws Yelemees thiab Europe los ua ib kauj ruam tseem ceeb rau yav tom ntej ntawm kev sib txuas lus ntawm tes, thaum tib lub sij hawm ua ib qho tseem ceeb rau lub teb chaws kev tswj hwm thev naus laus zis," Mikula tau hais.
E-band module muab 1W ntawm linear tso zis hluav taws xob los ntawm 81 GHz mus rau 86 GHz los ntawm kev sib txuas lub zog xa hluav taws xob ntawm plaub cais modules nrog qhov tsis tshua muaj kev poob waveguide sib dhos.Qhov no ua rau nws tsim nyog rau broadband point-to-point cov ntaub ntawv txuas mus ntev, lub peev xwm tseem ceeb rau yav tom ntej 6G architectures.
Ntau yam kev sim sib kis los ntawm Fraunhofer HHI tau ua kom pom qhov ua tau zoo ntawm cov khoom sib koom ua ke: hauv ntau qhov xwm txheej sab nraum zoov, cov teeb liab ua raws li 5G kev txhim kho tam sim no (5G-NR Tso Tawm 16 ntawm 3GPP GSM tus qauv).Ntawm 85 GHz, bandwidth yog 400 MHz.
Nrog rau kab-ntawm-pom pom, cov ntaub ntawv tau ua tiav tiav mus txog 600 meters hauv 64-cim Quadrature Amplitude Modulation (64-QAM), muab kev ua haujlwm siab bandwidth ntawm 6 bps / Hz.Lub teeb liab tau txais qhov yuam kev vector magnitude (EVM) yog -24.43 dB, zoo hauv qab 3GPP txwv ntawm -20.92 dB.Vim tias txoj kab ntawm qhov pom yog thaiv los ntawm cov ntoo thiab cov tsheb nres, 16QAM modulated cov ntaub ntawv tuaj yeem xa mus tau zoo txog 150 meters.Quadrature modulation data (quadrature phase shift keying, QPSK) tseem tuaj yeem kis tau thiab tau txais kev ua tiav ntawm qhov ua tau zoo ntawm 2 bps / Hz txawm tias txoj kab pom ntawm transmitter thiab receiver raug thaiv tag nrho.Hauv txhua qhov xwm txheej, lub teeb liab-rau-lub suab nrov sib piv, qee zaum dhau ntawm 20 dB, yog qhov tseem ceeb, tshwj xeeb tshaj yog xav txog qhov ntau zaus, thiab tsuas yog ua tiav los ntawm kev nce kev ua haujlwm ntawm cov khoom.
Nyob rau hauv qhov thib ob txoj kev, ib tug transmitter module tau tsim rau ib tug zaus ntawm ib ncig ntawm 140 GHz, combining ib tug tso zis hwj chim ntawm tshaj 100 mW nrog ib tug siab tshaj plaws bandwidth ntawm 20 GHz.Kev sim ntawm qhov module no tseem ua ntej.Ob lub transmitter modules yog cov khoom siv zoo tshaj plaws rau kev tsim thiab sim 6G systems yav tom ntej hauv terahertz zaus ntau.
