5G, lub thib tsib tiam kev sib txuas lus mobile technology yog ib tiam tshiab ntawm broadband mobile kev sib txuas lus technology nrog cov yam ntxwv ntawm kev kub ceev, qeeb qeeb thiab loj kev twb kev txuas.Nws yog lub network infrastructure kom paub txog cov txiv neej-tshuab thiab cov khoom sib cuam tshuam.
Internet ntawm tej yam yog lub ntsiab tau txais txiaj ntsig ntawm 5G.Lub ntsiab tsav tsheb ntawm 5G tsis yog tsuas yog qhov kev xav tau ntawm cov neeg siv khoom siv rau kev sib txuas sai dua, tab sis kuj tseem muaj kev loj hlob ntawm cov khoom siv sib txuas hauv ib puag ncig kev lag luam.Cov kev lag luam no vam khom rau cov cuab yeej sib txuas los sau thiab txheeb xyuas cov ntaub ntawv, ua kom cov txheej txheem kev lag luam muaj txiaj ntsig zoo, txhim kho cov khoom tsim tau, thiab txuas ntxiv txhim kho cov khoom thiab cov kev pabcuam.5G xav tias yuav pab tau cov lag luam kom tswj tau cov ntaub ntawv loj zuj zus los ntawm Is Taws Nem ntawm cov khoom, thiab txhim kho cov kev xa xov ze ze uas xav tau rau cov kev pabcuam tseem ceeb xws li kev phais neeg hlau lossis kev tsav tsheb.
Circulator thiab cais tawm yog ib qho ntawm cov khoom siv tseem ceeb ntawm 5G hauv paus chaw nres tsheb.Tag nrho cov kev sib txuas lus mobile feem ntau yog tsim los ntawm kev sib txuas lus hauv xov tooj ntawm tes, kev sib txuas lus xov tooj ntawm tes thiab cov khoom siv sib txuas lus mobile.Lub hauv paus chaw nres tsheb belongs rau cov cuab yeej yooj yim ntawm kev sib txuas lus mobile.Base chaw nres tsheb feem ntau yog tsim los ntawm RF pem hauv ntej-kawg, lub hauv paus chaw nres tsheb transceiver thiab lub hauv paus chaw nres tsheb maub los.RF pem hauv ntej-kawg yog lub luag hauj lwm rau cov teeb liab filtering thiab kev rho tawm, lub hauv paus chaw nres tsheb transceiver yog lub luag hauj lwm rau lub teeb liab tau txais, xa, amplifying thiab txo, thiab lub hauv paus chaw nres tsheb maub los yog lub luag hauj lwm rau cov teeb liab tsom xam, ua thiab lub hauv paus chaw nres tsheb tswj.Hauv kev siv wireless network, circulator feem ntau yog siv los cais tawm cov teeb liab tawm thiab cov teeb liab tawm ntawm lub hauv paus chaw nres tsheb kav hlau txais xov.Rau cov kev siv tshwj xeeb, lub circulator tuaj yeem ua tiav cov haujlwm hauv qab no nrog rau lwm yam khoom siv:
1. Nws tuaj yeem siv los ua tus kav hlau txais xov;
2. Ua ke nrog BPF nrog ceev attenuation, nws yog siv nyob rau hauv yoj splitting circuit;
3. Lub davhlau ya nyob twg resistor txuas nrog rau sab nraud ntawm lub circulator raws li ib qho kev sib cais, uas yog, lub teeb liab yog input thiab tso zis los ntawm qhov chaw nres nkoj;
4. Txuas lub ATT sab nraud thiab siv nws ua lub voj voog uas muaj kev cuam tshuam txog lub hwj chim tshawb pom.
Raws li ib qho ntawm cov khoom tseem ceeb tshaj plaws, ob daim ntawmSamarium Cobalt disc hlau nplaummuab cov hlau nplaum uas tsim nyog rau kev sib tw ntawm ferrite-loaded junction.Vim yog cov yam ntxwv ntawm kev tiv thaiv corrosion zoo heev thiab ua haujlwm ruaj khov siab txog 350 ℃, ob qho tib si SmCo5 thiab Sm2Co17 hlau nplaum yog siv rau hauv circulators lossis cais tawm.
Nrog rau daim ntawv thov ntawm 5G loj MIMO thev naus laus zis, kev noj ntawm cov circulators thiab cais tawm tau nce ntxiv, thiab qhov chaw ua lag luam yuav ncav cuag ntau zaus ntawm 4G.Hauv 5G era, qhov yuav tsum tau muaj peev xwm ntawm lub network yog ntau dua li ntawm 4G.Loj MIMO (Multiple-Input Multiple-Output) yog ib qho ntawm cov thev naus laus zis tseem ceeb los txhim kho lub peev xwm network.Txhawm rau txhawb nqa cov thev naus laus zis no, tus naj npawb ntawm 5G kav hlau txais xov yuav nce ntxiv, thiab tus naj npawb ntawm cov kav hlau txais xov ib leeg yuav nce los ntawm 4 raws thiab 8 raws hauv 4G lub sijhawm rau 64 raws.Qhov ob npaug ntawm cov xov tooj ntawm cov channel tseem yuav ua rau muaj kev nce ntxiv hauv qhov kev thov rau cov circulators sib raug zoo thiab cais tawm.Nyob rau tib lub sijhawm, rau cov kev xav tau ntawm lub teeb yuag thiab miniaturization, cov kev xav tau tshiab rau ntim thiab qhov hnyav tau muab tso rau pem hauv ntej.Tsis tas li ntawd, vim yog kev txhim kho ntawm kev ua haujlwm zaus band, lub teeb liab nkag mus yog qhov tsis zoo thiab qhov txo qis yog qhov loj, thiab qhov chaw nres tsheb hauv paus ceev ntawm 5G yuav siab dua li ntawm 4G.Yog li ntawd, nyob rau hauv 5G era, kev siv cov circulators thiab cais tawm, thiab ces Samarium Cobalt hlau nplaum yuav nce ntau.
Tam sim no cov tuam txhab tseem ceeb ntawm circulator / cais tawm hauv ntiaj teb suav nrog Skyworks hauv Asmeskas, SDP hauv Canada, TDK hauv Nyiv, HTD hauv Suav teb, thiab lwm yam.
