GaN E-band Ikwirakwiza Module ya 6G Itumanaho rya mobile

Kugeza 2030, itumanaho rya terefone ngendanwa 6G riteganijwe gutanga inzira kubikorwa bishya nkubwenge bwubuhanga, ukuri kugaragara hamwe na interineti yibintu.Ibi bizakenera imikorere irenze 5G igendanwa igezweho ukoresheje ibisubizo bishya byibyuma.Nkibyo, kuri EuMW 2022, Fraunhofer IAF izerekana module ikoresha ingufu za GaN itanga ingufu zateguwe hamwe na Fraunhofer HHI kumurongo wa 6G uhwanye na 70 GHz.Imikorere yo hejuru yiyi module yemejwe na Fraunhofer HHI.
Ibinyabiziga byigenga, telemedisine, inganda zikoresha - ibyo byose bizakoreshwa mu gihe kizaza mu bwikorezi, ubuvuzi n’inganda bishingiye ku ikoranabuhanga mu itumanaho n’itumanaho rirenze ubushobozi bw’ibisekuru bitanu bigezweho (5G).Biteganijwe ko hashyirwaho itumanaho rya telefone zigendanwa 6G mu 2030 risezeranya gutanga imiyoboro ikenewe yihuta ku mibare ikenewe mu gihe kiri imbere, hamwe n’ibiciro by’amakuru arenga 1 Tbps n’ubukererwe bugera kuri 100 µs.
Kuva muri 2019 nkumushinga wa KONFEKT (“6G Ibice byitumanaho”).
Abashakashatsi bakoze uburyo bwo kohereza bushingiye kuri gallium nitride (GaN) semiconductor, ku nshuro yabo ya mbere ishobora gukoresha inshuro zigera kuri 80 GHz (E-band) na 140 GHz (D-band).Module yohereza udushya ya E-band, imikorere yayo yageragejwe neza na Fraunhofer HHI, izashyikirizwa impuguke mu cyumweru cy’iburayi Microwave (EuMW) i Milan mu Butaliyani, kuva ku ya 25 kugeza ku ya 30 Nzeri 2022.
Dr. Michael Mikulla wo muri Fraunhofer IAF, uhuza umushinga wa KONFEKT asobanura agira ati: “Kubera ibisabwa cyane ku mikorere no gukora neza, 6G isaba ubwoko bushya bw'ibikoresho.”Ati: “Ibigezweho muri iki gihe bigeze aho bigarukira.Ibi birakoreshwa cyane cyane muburyo bwa tekinoroji ya semiconductor, hamwe na tekinoroji ya antenna.Kugirango tugere ku bisubizo byiza mubijyanye nimbaraga zisohoka, umurongo mugari hamwe nubushobozi bwimbaraga, dukoresha GaN ishingiye kuri monolithic ihuza Microwave Microwave Circuits (MMIC) ya module yacu isimbuza imiyoboro ya silicon ikoreshwa muri iki gihe. Nka semiconductor yagutse, GaN irashobora gukora kuri voltage nyinshi. , dutanga igihombo gito cyane hamwe nibindi bikoresho byoroheje. Byongeye kandi, turimo tuva kure yubuso bwubatswe hamwe nubushakashatsi bwateguwe kugirango dutezimbere igihombo gike cyo kubaka inyubako zikoresha imiyoboro ya interineti hamwe n’imyubakire ibangikanye. ”
Fraunhofer HHI nayo igira uruhare runini mugusuzuma 3D yacapishijwe umurongo.Ibice byinshi byateguwe, bikozwe kandi birangwa hifashishijwe uburyo bwo guhitamo lazeri yo gushonga (SLM), harimo amashanyarazi, antene na antenna.Inzira iremerera kandi umusaruro wihuse kandi uhenze cyane wibikoresho bidashobora gukorwa hakoreshejwe uburyo gakondo, bigatanga inzira yiterambere ryikoranabuhanga rya 6G.
Mikula yagize ati: "Binyuze muri ubwo buryo bushya bw'ikoranabuhanga, Ikigo cya Fraunhofer IAF na HHI cyemerera Ubudage n'Uburayi gutera intambwe y'ingenzi igana ahazaza h'itumanaho rya terefone igendanwa, mu gihe kimwe kandi bigira uruhare runini mu busugire bw'ikoranabuhanga mu gihugu".
Moderi ya E-band itanga 1W yumurongo wumurongo uva kuri 81 GHz kugeza kuri 86 GHz muguhuza imbaraga zo kohereza modules enye zitandukanye hamwe ninteko yo gutakaza cyane.Ibi bituma bikwiranye na Broadband point-to-point data ihuza intera ndende, ubushobozi bwingenzi bwububiko bwa 6G.
Ubushakashatsi butandukanye bwo kohereza bwakozwe na Fraunhofer HHI bwerekanye imikorere yibice byatejwe imbere: mubihe bitandukanye byo hanze, ibimenyetso bihuye nibisobanuro byiterambere rya 5G (5G-NR Isohora 16 rya 3GPP GSM).Kuri 85 GHz, umurongo wa 400 MHz.
Hamwe n'umurongo-wo-kureba, amakuru yoherejwe neza kugeza kuri metero 600 muri 64-ikimenyetso cya Quadrature Amplitude Modulation (64-QAM), itanga umurongo mwinshi wa 6 bps / Hz.Ikimenyetso cyakiriwe nikibazo cya vector ubunini (EVM) ni -24.43 dB, munsi yumupaka wa 3GPP wa -20.92 dB.Kuberako umurongo wo kureba uhagaritswe nibiti hamwe nibinyabiziga bihagaze, amakuru yahinduwe 16QAM arashobora koherezwa neza kugeza kuri metero 150.Guhindura amakuru ya Quadrature (icyiciro cya kane cyo guhinduranya urufunguzo, QPSK) irashobora kwanduzwa kandi igakirwa neza ku bushobozi bwa 2 bps / Hz nubwo umurongo wo kureba hagati ya transmitteri niyakira byahagaritswe burundu.Mubihe byose, igipimo kinini cyerekana-urusaku, rimwe na rimwe kirenga 20 dB, ni ngombwa, cyane cyane urebye intera yumurongo, kandi birashobora kugerwaho gusa no kongera imikorere yibigize.
Muburyo bwa kabiri, module ya transmitter yatunganijwe kumurongo wa interineti hafi ya GHz 140, uhuza ingufu zisohoka mW zirenga 100 mW hamwe nubunini ntarengwa bwa 20 GHz.Kugerageza iyi module biracyari imbere.Byombi byohereza modul nibintu byiza byogutezimbere no kugerageza sisitemu ya 6G mugihe cya terahertz.
Nyamuneka koresha iyi fomu niba uhuye namakosa yimyandikire, adahwitse, cyangwa ushaka gutanga icyifuzo cyo guhindura ibiri muriyi page.Kubibazo rusange, nyamuneka koresha urupapuro rwitumanaho.Kubitekerezo rusange, koresha igice cyibitekerezo rusange hepfo (kurikiza amategeko).
Igitekerezo cyawe ni ingenzi cyane kuri twe.Ariko, kubera ubwinshi bwubutumwa, ntidushobora kwemeza ibisubizo byihariye.
Aderesi imeri yawe ikoreshwa gusa kugirango umenyeshe abayohereje imeri.Ntabwo adresse yawe cyangwa aderesi yabakiriye bizakoreshwa kubindi bikorwa byose.Amakuru winjiye azagaragara muri imeri yawe kandi ntabwo azabikwa na Tech Xplore muburyo ubwo aribwo bwose.
Uru rubuga rukoresha kuki kugirango rworohereze inzira, gusesengura imikoreshereze ya serivisi zacu, gukusanya amakuru kugirango wamamaze iyamamaza, kandi utange ibikubiye mu bandi bantu.Ukoresheje urubuga rwacu, wemera ko wasomye kandi wunvise Politiki Yibanga yacu namategeko agenga imikoreshereze.
