Ni ubuhe buryo bwa 5G NR Umuyoboro w'ikimenyetso?

Ibimenyetso bya milimetero bitanga umurongo mugari hamwe nigipimo cyinshi cyamakuru kuruta ibimenyetso bike. Reba kumurongo rusange wibimenyetso hagati ya antenne na baseband ya digitale.
Radiyo nshya 5G (5G NR) yongeramo milimetero yumurongo wibikoresho bya selile. Hamwe nibi haza urunigi rwerekana ibimenyetso bya RF-kuri-baseband hamwe nibice bidasabwa kuri frequence iri munsi ya 6 GHz. Mugihe milimetero yumurongo wumurongo wa tekinike uri hagati ya 30 na 300 GHz, kubwintego ya 5G kuva kuri 24 kugeza 90 GHz, ariko mubisanzwe igera kuri GHz 53. Porogaramu ya milimetero yabanje kwitezwaho gutanga amakuru yihuse kuri terefone zigendanwa mumijyi, ariko kuva yimukira murwego rwo hejuru rwimikoreshereze nka stade. Irakoreshwa kandi muburyo butemewe bwo gukoresha (FWA) serivisi za interineti hamwe nuyoboro wigenga.
Inyungu zingenzi za 5G mmWave Umuyoboro mwinshi wa 5G mmWave yemerera kohereza amakuru manini (10 Gbps) hamwe numuyoboro mugari wa GHz 2 (nta guteranya abitwara). Iyi mikorere ikwiranye numuyoboro ufite amakuru manini akenewe. 5G NR ituma kandi ubukererwe buke bitewe nigipimo kinini cyo kohereza amakuru hagati yumurongo wa radiyo 5G hamwe numuyoboro. Imiyoboro ya LTE ifite ubukererwe bwa milisegonda 100, mugihe imiyoboro ya 5G ifite ubukererwe bwa milisegonda 1 gusa.
Niki kiri mumurongo wa signal ya mmWave? Imirongo ya radiyo yumurongo (RFFE) isobanurwa nkibintu byose hagati ya antenne na sisitemu ya baseband. RFFE ikunze kuvugwa nkigereranya-kuri-digitale igice cyakira cyangwa cyohereza. Igishushanyo cya 1 cyerekana imyubakire yitwa guhinduka mu buryo butaziguye (zeru NIBA), aho amakuru ahindura akorera ku kimenyetso cya RF.
Igishushanyo 1. Iyi 5G mmWave yerekana ibimenyetso byuruhererekane rwubaka ikoresha icyitegererezo cya RF; Nta inverter isabwa (Ishusho: Ibisobanuro muri make).
Urunigi rw'ibimenyetso bya milimetero rugizwe na RF ADC, RF DAC, akayunguruzo gato, akongerera ingufu (PA), ibyuma bya digitale hasi no hejuru bihinduranya, akayunguruzo ka RF, ibyuma byongera urusaku ruke (LNA), hamwe na generator yisaha ya digitale ( KANDA). Icyiciro gifunze loop / voltage igenzurwa na oscillator (PLL / VCO) itanga oscillator yaho (LO) kubahindura hejuru no hepfo. Guhindura (byerekanwe ku gishushanyo cya 2) bihuza antenne na signal yakira cyangwa ikwirakwiza umuziki. Ntabwo yerekanwe ni IC imurika (BFIC), izwi kandi nk'icyiciro cya array kristal cyangwa beamformer. BFIC yakira ibimenyetso bivuye kuri upconverter ikabigabanyamo imiyoboro myinshi. Ifite kandi icyiciro cyigenga kandi ikunguka kugenzura kuri buri muyoboro wo kugenzura ibiti.
Iyo ikorera muburyo bwo kwakira, buri muyoboro uzaba ufite icyiciro cyigenga kandi wunguke kugenzura. Iyo downconverter ifunguye, yakira ibimenyetso ikanayinyuza muri ADC. Kuruhande rwimbere hari imbaraga zongerewe imbaraga, LNA hanyuma amaherezo. RFFE ituma PA cyangwa LNA ukurikije niba iri muburyo bwo kohereza cyangwa kwakira uburyo.
Transceiver Igishushanyo cya 2 cyerekana urugero rwa transceiver ya RF ukoresheje IF urwego hagati ya baseband na 24.25-29.5 GHz ya milimetero ya milimetero. Ubu bwubatsi bukoresha 3.5 GHz nkibisanzwe NIBA.
Kohereza ibikorwa remezo bidafite umugozi wa 5G bizagirira akamaro cyane abatanga serivisi n'abaguzi. Amasoko yingenzi yatanzwe ni selile ya Broadband modules hamwe na 5G itumanaho kugirango itume interineti yinganda yibintu (IIOT). Iyi ngingo yibanze kuri milimetero yumurongo wa 5G. Mu ngingo zizaza, tuzakomeza kuganira kuriyi nsanganyamatsiko kandi twibande ku buryo burambuye ku bintu bitandukanye bigize 5G mmWave yerekana urunigi.
Suzhou Cowin itanga ubwoko bwinshi bwa RF 5G 4G LTE 3G 2G GSM GPRS antenne selile, hamwe ninkunga yo gukuramo antenne ikora neza kubikoresho byawe hamwe no gutanga raporo yuzuye yo gupima antenne, nka VSWR, kunguka, gukora neza hamwe nimirasire ya 3D.
