5G Circulator thiab Isolator SmCo Magnet

5G, the fifth tiam mobile sib txuas lus tshuab yog ib tiam tshiab ntawm broadband mobile sib txuas lus tshuab nrog cov yam ntxwv ntawm kev kub ceev, qeeb qeeb thiab kev sib txuas loj. Nws yog lub network cov txheej txheem kom paub txog tus txiv neej-tshuab thiab khoom sib txuas.

5G Characteristics

Is Taws Nem ntawm yam yog qhov txiaj ntsig tseem ceeb ntawm 5G. Lub zog tseem ceeb ntawm 5G tsis yog tsuas yog qhov kev thov nce ntxiv ntawm cov neeg siv khoom rau cov kev sib txuas sai, tab sis kuj tseem nthuav dav ntawm cov khoom siv sib txuas hauv cov chaw tsim khoom. Cov kev lag luam no nce siab rau kev sib koom tes sib tham los sau thiab txheeb xyuas cov ntaub ntawv, ua kom cov txheej txheem kev lag luam muaj txiaj ntsig, txhim kho khoom lag luam, thiab txuas ntxiv txhim kho cov khoom thiab cov kev pabcuam. 5G cia siab tias yuav pab ua lag luam kom tswj tau cov ntaub ntawv ntau ntxiv hauv Is Taws Nem cov khoom, thiab txhim kho kev xa xov uas yuav tsum tau ua sai sai rau lub hom phiaj tseem ceeb xws li kev pabcuam neeg hlau pab phais mob lossis kev tsav tsheb tsis zoo

5G Applications

Circulator thiab isolator yog ib qho ntawm cov khoom siv tseem ceeb ntawm 5G hauv paus chaw nres tsheb. Tag nrho cov txheej txheem kev sib txuas lus ntawm mobile feem ntau yog tsim los ntawm cov kev sib txuas lus ntawm kev sib txuas lus mobile, kev sib txuas lus ntawm kev sib txuas lus mobile thiab cov khoom siv sib txuas lus mobile kawg. Qhov pib chaw nres tsheb belongs rau cov khoom siv yooj yim ntawm kev sib txuas lus txawb. Base station system feem ntau yog tsim los ntawm RF pem hauv ntej-xaus, hauv paus chaw nres tsheb transceiver thiab puag chaw nres tsheb maub los. Lub RF hauv ntej-kawg yog lub luag haujlwm rau cov teeb liab lim thiab cais tawm, lub hauv paus chaw nres tsheb transceiver yog lub luag haujlwm rau cov teeb liab txais, xa, ua kom nrov thiab txo qis, thiab cov tswj hwm chaw nres tsheb yog lub luag haujlwm rau teeb liab tsom, kev ua thiab chaw nres tsheb tswj. Hauv wireless nkag network, circulator tsuas yog siv cais tawm cov teeb liab tawm thiab cov teeb liab tawm tswv yim ntawm lub hauv paus nres tsheb kav hlau txais xov. Rau cov ntawv thov tshwj xeeb, lub circulator tuaj yeem ua tiav cov haujlwm hauv qab no nrog lwm cov khoom siv:

1. Nws tuaj yeem raug siv los ua kav hlau txais xov lub zog;

2. Hauv kev sib xyaw nrog BPF nrog kev ceev ceev, nws yog siv hauv nthwv dej sib cais;

3. Lub davhlau ya nyob twg resistor txuas nrog rau sab nraud ntawm lub circulator raws li kev cais tawm, uas yog, lub teeb liab yog cov tswv yim thiab cov khoom tawm los ntawm qhov chaw nres nkoj tsim;

4. Txuas lub sab nraud ATT thiab siv nws los ua lub tshuab pa hluav taws xob nrog lub zog nrhiav haujlwm.

Raws li ib qho ntawm cov tseem ceeb tshaj plaws, ob daim ntawm Samarium Cobalt disc hlau nplaummuab cov lus sib nqus tsim nyog kom muaj qhov kev txiav txim siab ntawm qhov nruab nrab ferrite-loaded. Vim muaj cov yam ntxwv ntawm kev tiv thaiv yav tom ntej thiab kev ua haujlwm ruaj khov siab rau 350 ℃ degrees, ob qho tib si SmCo5 thiab Sm2Co17 cov hlau nplaum tau siv rau hauv cov twj lossis circulators.

5G Circulator and Isolator SmCo MagnetCirculator

Nrog rau kev thov ntawm 5G loj MIMO thev naus laus zis, kev noj cov circulators thiab cov cais tawm tau nce ntau, thiab qhov chaw lag luam yuav ncav cuag ntau zaus ntawm 4G. Hauv 5G era, qhov xav tau ntawm lub peev xwm network yog ntau dua li ntawm 4G. MIMO huab hwm coj (ntau yam-tawm ntau ntau-tawm lus) yog ib qho ntawm cov thev naus laus zis los txhim kho lub peev xwm hauv network. Txhawm rau txhawb nqa cov thev naus laus zis no, cov xov tooj ntawm 5G kav hlau txais xov yuav nce siab, thiab tus naj npawb ntawm ib qho kev thaiv kav hlau txais xov yuav nce los ntawm 4 channel thiab 8 channel hauv 4G lub sijhawm mus txog 64 channel. Txoj kev hloov siab txog ob npaug ntawm cov channel yuav tseem yuav ua rau qhov kev nce ntxiv ntawm qhov kev thov rau cov ntsuas ncig thiab cais tawm. Tib lub sijhawm, rau cov kev xav tau ntawm lub cev yuag thiab miniaturization, qhov xav tau tshiab rau ntim thiab qhov hnyav tau muab tso rau pem hauv ntej. Tsis tas li ntawd xwb, vim muaj kev txhim kho ntawm cov ua haujlwm zaus ua haujlwm ntau dua, lub teeb liab nkag mus tsis zoo thiab qhov ua kom pom qhov loj yog qhov loj, thiab qhov chaw nres tsheb ceev ntawm 5G yuav siab dua li ntawm 4G. Yog li ntawd, hauv 5G era, kev siv cov circulators thiab cais tawm, thiab tom qab ntawd Samarium Cobalt hlau nplaum yuav nce siab.

MIMO

Tam sim no cov tseem ceeb tsim ntawm circulator / isolator nyob hauv lub ntiaj teb suav nrog Skyworks hauv Asmeskas, SDP hauv Canada, TDK hauv Nyij Pooj, HTD hauv Suav Teb, thiab lwm yam.
