RF Lim: Qhov tseem ceeb tseem ceeb ntawm cov khoom siv sib txuas lus wireless

RF lim, raws li cov khoom tseem ceeb ntawm kev sib txuas lus wireless, ua tiav cov teeb liab optimization thiab txhim kho kev sib kis tau zoo los ntawm kev xaiv lim cov cim zaus. Nyob rau hauv niaj hnub no lub ntiaj teb no heev kev cob cog rua, lub luag hauj lwm ntawmRF limtsis tuaj yeem tsis quav ntsej.

Lub luag haujlwm tseem ceeb thiab cov yam ntxwv ntawmRF lim

RF limtuaj yeem txhim kho kev ua tau zoo ntawm kev sib txuas lus los ntawm kev tsis lees paub cov cim tsis xav tau thiab tso cai rau cov phiaj xwm zaus dhau los. Lawv tau siv dav hauv kev sib txuas lus hauv xov tooj, kev sib txuas lus satellite, radar, thiab Is Taws Nem ntawm Yam (IoT) cov khoom siv.

Kev ua haujlwm siabRF limyuav tsum muaj cov yam ntxwv hauv qab no:

Kev poob qis qis: xyuas kom meej qhov tsawg kawg nkaus attenuation nyob rau hauv lub passband.

Kev sib cais siab thiab nres attenuation: zoo thaiv cov cim tsis yog lub hom phiaj thiab txo kev cuam tshuam.

High Q tus nqi: txhim kho qhov kev xaiv thiab qhov tseeb ntawm lub lim.

Kev ua tau zoo passive intermodulation (PIM) kev ua tau zoo: txo cov teeb liab intermodulation cuam tshuam thiab txhim kho qhov system stability.

Miniaturized tsim: yoog raws li cov kev xav tau ntawm cov khoom siv niaj hnub no rau cov qauv kev cog lus thaum ua kom muaj peev xwm tuav tau lub zog.

Hom ntawmRF lim

Raws li cov khoom siv thiab kev tsim khoom,RF limtuaj yeem muab faib ua ntau hom:
Cavity lim
Dielectric lim
Coaxial lim
Planar Lim
Electroacoustic Lim
Txhua lub lim dej muaj qhov tshwj xeeb zoo hauv kev tsim, kev ua tau zoo thiab daim ntawv thov scenarios, thiab tuaj yeem ua tau raws li qhov xav tau ntawm kev sib txuas lus wireless sib txawv.

Kev Lag Luam Kev Lag Luam

Nrog rau qhov nrov ntawm 5G tes hauj lwm thiab kev nce hauv cov ntawv thov hauv millimeter yoj band, kev ua lag luam xav tau ntau dua thiab kev ua haujlwm siab duaRF limyog tsis tu ncua. Tsis tas li ntawd, qhov nce ntawm IoT cov cuab yeej kuj tau muab ntau txoj hauv kev rau kev tsim kho thev naus laus zis ntawm RF lim.

Qhov tseem ceeb ntawmRF lim

Hauv kev sib txuas lus wireless, lub luag haujlwm ntawmRF limtsis txwv rau kev hla cov cim zaus tshwj xeeb, tab sis kuj suav nrog kev tiv thaiv kev cuam tshuam ntau zaus thiab ua kom lub teeb pom kev zoo. Cov khoom siv wireless niaj hnub xav tau cov ntxaij lim dej uas muaj cov resonators, waveguides lossis passive Cheebtsam los txhawb lawv txoj haujlwm sib txuas lus. Txhua yam cuab yeej cia siab rauRF limlos xyuas kom meej kev sib kis tau zoo thiab kev ntseeg tau ntawm cov teeb liab.

Cov ntsiab lus

Raws li ib feem tseem ceeb ntawm kev sib txuas lus wireless,RF limua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm cov khoom siv. Los ntawm smartphones mus rau radar systems rau IoT terminals, daim ntawv thov thaj chaw ntawmRF limtxuas ntxiv mus. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev nce hauv kev thov rau kev sib txuas lus wireless,RF limyuav ua lub luag haujlwm tseem ceeb dua hauv kev ua lag luam yav tom ntej.
Yog hais tias koj tab tom nrhiav rau high-zooRF limkev daws teeb meem, peb tuaj yeem muab rau koj nrog ntau hom qauv lossis kev xaiv, thiab coj koj cov khoom nrog peb lub xyoo lav kev pabcuam! Thov koj xav tiv tauj peb kom paub ntau ntxiv.
