IQ Mixers RF Microwave millimeter millimeter tos xov tooj cua
Microwave mixers yog hom tshwj xeeb ntawm cov tov khoom uas muaj ob txoj kev teeb liab theem hu ua "hauv-theem" (q). Nws cov yam ntxwv muaj raws li hauv qab no:
1. Muab cov ntsiab lus theem thiab cov ntaub ntawv tshaj tawm: Vim tias muaj kev suav nrog ntawm I thiab Qhab ntxau IQ tov khoom tuaj yeem muab cov ntaub ntawv theem thiab amplitude ntawm lub teeb liab. Qhov no yog qhov tseem ceeb rau ntau cov tshuab sib txuas lus thiab kev sib txuas lus thiab cov txheej txheem demodulation.
2. Paub txog cov teeb meem orthogonal) Qhov no ua rau xov tooj cua ntau heev muaj txiaj ntsig zoo, xws li Orthoogen Furnity Furnival ntau txoj kev nkag tau (OFDRM) thiab quadrrifature geebtulate (qab).
3. Txo cov kev cuam tshuam kev sib cuam tshuam: IQ cov khoom tov yog tuaj yeem cais cov teeb liab thiab kev cuam tshuam rau kev suav nrog theem kev suav sib txuam. Qhov no ua rau nws muaj peev xwm ua tau los ntawm kev sib cuam tshuam eavesdroding eavesdroding.
4. Kev siv ntau yam siab: vim tias kev siv ob channel, iQ mixers feem ntau muaj cov ntawv thov ua tau zoo uas tuaj yeem ua tau cov phiajcim ua kom tiav.
Cov tov khoom siv IQ feem ntau yog siv hauv cov hauv qab no:
1. Kev sib txuas lus sib txuas lus: millimeter khiav tawm hauv lub tshuab sib txuas lus, suav nrog kev sib txuas lus siv mobile, satellite kev sib txuas lus systems thiab wireless cov chaw sib txuas lus hauv cheeb tsam. Nws yog siv los Demodulate cov teeb liab tau txais, coj tus teeb liab xa, thiab paub qhov demodulation, kev hloov pauv thiab ntau zaus hloov dua siab tshiab ntawm lub teeb liab.
2.Modem: iQ cov kev sib xyaw ua ke yog pom tias muaj feem cuam tshuam nrog kev sib xyaw rau kev sib xyaw, lossis sib xyaw ua ke tau txais RFBand rau hauv Baseband rau qhov kev rhuav tshem.
3.Qhov-ceev cov ntaub ntawv sib kis: vim tias IQ Mixers tuaj yeem tswj cov cim orthogon, lawv muaj cov ntawv thov tseem ceeb hauv cov ntaub ntawv xa ceev. Piv txwv li, hauv kev sib txuas lus kho qhov muag thiab kev sib txuas lus kub ceev thiab siv cov mixers demoidation thiab demodulation siv tau kom muaj kev sib kis tau zoo thiab muaj peev txheej siab.
4.Carrier cuam tshuam kev txheeb xyuas: IQ Mixers tuaj yeem siv rau cov muaj kev cuam tshuam nrog kev cuam tshuam los ntawm kev ntsuas thiab ntsuas cov ntsiab lus ntawm lub teeb liab.
Tsim nyogInc. Cov khoom siv IQ-Mixers ua haujlwm los ntawm 1.75 rau 26GHz.
