Cov Lim Dej RF: Cov Cheebtsam Tseem Ceeb ntawm Cov Khoom Siv Sib Txuas Lus Wireless

Cov lim dej RF, ua cov khoom tseem ceeb ntawm cov kab ke sib txuas lus wireless, ua tiav qhov kev ua kom zoo dua ntawm cov teeb liab thiab txhim kho qhov zoo ntawm kev sib kis los ntawm kev xaiv cov teeb liab zaus. Hauv lub ntiaj teb niaj hnub no uas txuas nrog heev, lub luag haujlwm ntawmCov lim dej RFtsis tuaj yeem tsis quav ntsej.

Cov Haujlwm Tseem Ceeb thiab Cov Nta ntawmCov lim dej RF

Cov lim dej RFtuaj yeem txhim kho qhov ua tau zoo ntawm cov kab ke sib txuas lus los ntawm kev tsis lees txais cov teeb liab tsis xav tau thiab tso cai rau cov teeb liab zaus kom dhau mus. Lawv siv dav hauv kev sib txuas lus ntawm tes, kev sib txuas lus satellite, radar, thiab Internet of Things (IoT) cov khoom siv.

Kev ua tau zoo heevCov lim dej RFyuav tsum muaj cov yam ntxwv hauv qab no:

Kev poob qis ntawm kev ntxig: xyuas kom meej tias qhov teeb liab tsawg kawg nkaus hauv qhov passband.

Kev rho tawm siab thiab kev txo qis ntawm cov kab nres: thaiv cov teeb liab uas tsis yog lub hom phiaj thiab txo qhov cuam tshuam.

Tus nqi Q siab: txhim kho qhov kev xaiv thiab qhov tseeb ntawm lub lim.

Kev ua tau zoo heev ntawm passive intermodulation (PIM): txo cov teeb liab cuam tshuam thiab txhim kho kev ruaj khov ntawm lub cev.

Kev tsim qauv me me: hloov kho rau qhov xav tau ntawm cov khoom siv niaj hnub rau cov qauv me me thaum ua kom muaj peev xwm tswj hwm lub zog.

Hom ntawmCov lim dej RF

Raws li cov ntaub ntawv thiab cov txheej txheem tsim khoom,Cov lim dej RFmuaj peev xwm muab faib ua ntau hom:
Cov lim dej cavity
Cov lim dej dielectric
Cov lim dej coaxial
Cov lim dej planar
Cov lim dej electroacoustic
Txhua lub lim dej muaj qhov zoo tshwj xeeb hauv kev tsim qauv, kev ua tau zoo thiab cov xwm txheej ntawm daim ntawv thov, thiab tuaj yeem ua tau raws li qhov xav tau ntawm cov kab ke sib txuas lus wireless sib txawv.

Cov Qauv Lag Luam

Nrog rau kev nrov ntawm 5G tes hauj lwm thiab kev nce ntxiv ntawm cov ntawv thov hauv millimeter wave band, kev lag luam xav tau ntau zaus thiab kev ua tau zoo duaCov lim dej RFtab tom loj hlob zuj zus. Tsis tas li ntawd, qhov nce ntawm cov khoom siv IoT kuj tau muab ntau txoj hauv kev rau kev tsim kho tshiab ntawm cov lim dej RF.

Qhov Tseem Ceeb ntawmCov lim dej RF

Hauv cov txheej txheem sib txuas lus wireless, lub luag haujlwm ntawmCov lim dej RFtsis yog tsuas yog xa cov teeb liab zaus tshwj xeeb xwb, tab sis kuj suav nrog kev tiv thaiv cov zaus cuam tshuam thiab ua kom zoo dua qhov zoo ntawm cov teeb liab. Cov khoom siv wireless niaj hnub xav tau cov lim dej uas muaj cov resonators, waveguides lossis cov khoom passive los txhawb lawv cov haujlwm sib txuas lus. Txhua lub cuab yeej vam khom rauCov lim dej RFkom ntseeg tau tias muaj kev sib kis tau zoo thiab kev ntseeg tau ntawm cov teeb liab.

Kev Txheeb Xyuas

Raws li ib feem tseem ceeb ntawm cov txheej txheem sib txuas lus wireless,Cov lim dej RFua lub luag haujlwm tseem ceeb hauv kev ua haujlwm zoo ntawm cov khoom siv. Txij li cov xov tooj ntse mus rau radar systems mus rau IoT terminals, cov cheeb tsam ntawm daim ntawv thov ntawmCov lim dej RFtab tom nthuav dav tas li. Nrog rau kev nce qib ntawm thev naus laus zis thiab kev nce ntxiv ntawm qhov kev thov rau kev sib txuas lus wireless,Cov lim dej RFyuav ua lub luag haujlwm tseem ceeb dua hauv kev ua lag luam yav tom ntej.
