11 Txoj Kev Faib Faib Diav / Sib Txuas
Tus qauv ntawm lub hwj chim divider
Cov qauv ntawm lub hwj chim divider feem ntau yog tsim los ntawm cov tswv yim kawg, cov zis kawg, kev xav txog kawg, cov kab noj hniav resonant, thiab cov khoom siv hluav taws xob.Lub hauv paus ntsiab lus ua haujlwm ntawm lub zog faib hluav taws xob yog faib cov teeb liab tawm tswv yim rau hauv ob lossis ntau lub teeb liab tawm, nrog rau txhua qhov tso zis hluav taws xob muaj lub zog sib npaug.Lub reflector qhia txog cov teeb liab tawm tswv yim rau hauv ib lub resonant kab noj hniav, uas faib cov input teeb liab mus rau ob los yog ntau tshaj cov zis tawm tswv yim, txhua tus muaj sib npaug zog.
Lub 11 channel fais fab faib / sib txuas tuaj yeem ua tau raws li qhov yuav tsum tau muaj rau kev sib cais lossis sib txuas cov ntaub ntawv ntawm 11 cov khoom siv lossis cov khoom tawm.
Cov cim tseem ceeb ntawm lub zog faib hluav taws xob muaj xws li impedance txuam, ntxig qhov poob, cais degree, thiab lwm yam.
Nta:
1. Impedance txuam: Los ntawm kev faib cov khoom tsis sib xws (cov kab microstrip), qhov teeb meem ntawm impedance mismatch thaum lub sij hawm xa hluav taws xob yog daws, yog li ntawd cov input thiab output impedance qhov tseem ceeb ntawm lub hwj chim divider/combiner yuav tsum nyob ze li sai tau los txo cov teeb liab distortion.
2. Kev poob qis qis: Los ntawm kev tshuaj xyuas cov khoom siv hluav taws xob faib hluav taws xob, kev ua kom zoo ntawm cov txheej txheem tsim khoom, thiab txo qhov poob ntawm lub zog faib;Los ntawm kev xaiv cov qauv tsim nyog hauv lub network thiab cov ntsuas hluav taws xob, qhov kev faib hluav taws xob poob ntawm lub zog faib hluav taws xob tuaj yeem raug txo.Yog li ua tiav kev faib hluav taws xob tsis sib xws thiab qhov tsawg kawg nkaus poob.
3. Kev sib cais siab: Los ntawm kev ua kom muaj kev sib cais, cov teeb liab cuam tshuam ntawm cov chaw nres nkoj tso zis yog absorbed, thiab cov teeb liab cuam tshuam ntawm cov chaw nres nkoj tso zis ntau ntxiv, ua rau muaj kev sib cais siab.
Daim ntawv thov:
1. Lub zog faib hluav taws xob tuaj yeem siv los xa cov teeb liab mus rau ntau lub kav hlau txais xov lossis cov khoom txais, lossis faib cov teeb liab rau ntau qhov sib npaug.
2. Lub zog faib hluav taws xob tuaj yeem siv rau hauv cov khoom siv hluav taws xob hauv lub xeev, ncaj qha txiav txim siab qhov ua tau zoo, amplitude zaus tus yam ntxwv, thiab lwm yam kev ua tau zoo ntawm cov khoom siv hauv lub xeev transmitters.
Qualwaveinc.muab 11-Txoj kev fais fab faib / sib txuas hauv ntau zaus ntawm DC mus rau 1GHz, nrog lub zog txog li 2W.
