RF High Isolation BroadBand zaus Converters IQ Mixers
IQ Mixers yog hom tshwj xeeb ntawm cov khoom sib xyaw uas muaj ob txoj hauv kev sib txuas ua ke hu ua "In-theem" (I) thiab "Quadrature" (Q).Nws cov yam ntxwv yog raws li nram no:
1. Muab cov ntaub ntawv theem thiab amplitude: Vim muaj kev suav nrog I thiab Q raws, IQ tov khoom tuaj yeem muab cov ntaub ntawv theem thiab amplitude ntawm lub teeb liab.Qhov no yog qhov tseem ceeb rau ntau lub tshuab kev sib txuas lus wireless thiab kev hloov kho thiab kev ua haujlwm demodulation.
2. Paub txog cov teeb liab orthogonal ua: I thiab Q raws ntawm IQ tov khoom muaj peev xwm ua tiav cov teeb liab orthogonal, uas yog, cov teeb liab nrog theem sib txawv ntawm 90 degrees.Qhov no ua rau nws muaj txiaj ntsig zoo hauv ntau qhov kev hloov kho thiab kev ua haujlwm demodulation, xws li orthogonal zaus division multiple access (OFDM) thiab quadrature amplitude modulation (QAM).
3. Txo qhov kev cuam tshuam ntawm kev mloog: IQ tov khoom muaj peev xwm cais cov teeb liab thiab cuam tshuam spectrum vim muaj ob txoj hauv kev sib txuas ntxiv.Qhov no ua rau nws muaj peev xwm tiv thaiv kev cuam tshuam eavesdropping.
4. High dynamic range: Vim yog kev siv ob txoj kev, IQ mixers feem ntau muaj cov dynamic ntau yam uas muaj peev xwm ua tau raws li qhov xav tau ntawm cov teeb liab ua cov ntawv thov.
IQ mixer feem ntau yog siv hauv cov hauv qab no:
1.Wireless kev sib txuas lus systems: IQ mixer yog dav siv nyob rau hauv wireless kev sib txuas lus systems, xws li mobile kev sib txuas lus systems, satellite kev sib txuas lus systems thiab wireless hauv cheeb tsam network.Nws yog siv los demodulate lub teeb liab tau txais, hloov kho cov teeb liab xa mus, thiab paub txog qhov demodulation, kev hloov pauv thiab zaus hloov pauv ntawm lub teeb liab.
2.Modem: IQ mixers yog cov khoom tseem ceeb uas feem ntau pom nyob rau hauv modems uas yog siv los sib xyaw cov teeb liab baseband rau hauv RF ntau yam rau kev sib kis, lossis sib tov tau txais RF signals rau hauv baseband rau demodulation.
3.High-ceev cov ntaub ntawv kis tau tus mob: Vim hais tias IQ mixers muaj peev xwm lis orthogonal signals, lawv muaj ib tug tseem ceeb daim ntaub ntawv nyob rau hauv high-ceev cov ntaub ntawv kis tau tus mob.Piv txwv li, hauv kev sib txuas lus kho qhov muag thiab kev sib txuas lus digital high-speed, QAM kev hloov kho thiab kev txiav txim siab siv IQ mixers tuaj yeem ua kom muaj kev sib kis tau zoo thiab muaj peev xwm ua tau zoo.
4.Carrier cuam tshuam kev tsom xam: IQ mixers tuaj yeem siv rau kev cuam tshuam kev cuam tshuam ntawm cov cab kuj, uas tuaj yeem pab txiav txim siab qhov chaw cuam tshuam thiab tshem tawm kev cuam tshuam los ntawm kev ntsuas thiab txheeb xyuas cov theem thiab cov ntaub ntawv amplitude ntawm lub teeb liab.
QualwaveInc. muab cov khoom siv IQ-cov khoom sib xyaw ua haujlwm ntawm 1.75 txog 5GHz.
