Cov Khoom Sib Tov Microwave Sib Npaug

Lub Tshuab Sib Tov Fais Fab Sib Npaug yog ib lub cuab yeej siv hluav taws xob uas sib tov ob lub teeb liab ua ke los tsim cov teeb liab tso zis. Nws pab tau kom txhim kho qhov rhiab heev, kev xaiv, kev ruaj khov thiab kev sib xws ntawm cov ntsuas zoo ntawm lub receiver.

Nws cov yam ntxwv muaj xws li:

1. Kev tswj cov teeb liab tsis zoo: Los ntawm kev siv lub qauv sib npaug ntawm lub voj voog, koj tuaj yeem tswj cov teeb liab tsis zoo thiab kev cuam tshuam sab nraud ntawm lub teeb liab nkag, txhim kho qhov huv thiab zoo ntawm lub teeb liab.
2. Kev cuam tshuam qis dua ntawm intermodulation: Lub cim ntawm kev cuam tshuam intermodulation tuaj yeem txo qis vim tias nws cov qauv sib npaug muab cov teebmeem sib xyaw kom raug thiab raug dua los ntawm kev tawm tsam cov teebmeem tsis zoo ntawm cov khoom tsis sib xws.
3. Daim ntawv thov dav dav: nrog rau qhov dav dav, kev sib tov thiab kev ua cov teeb liab tuaj yeem ua tiav hauv ntau qhov zaus.
4. Kev ncaj ncaj siab: nws tuaj yeem muab cov teeb liab tso zis raug, thiab txhim kho qhov rhiab heev thiab ntau yam ntawm lub kaw lus.

RF Balanced mixers feem ntau yog siv rau hauv cov teb hauv qab no:

1. Cov txheej txheem sib txuas lus: Cov khoom sib xyaw sib npaug yog siv dav hauv cov txheej txheem sib txuas lus rau kev hloov pauv zaus, kev hloov kho thiab demodulation, Doppler radar, lub xov tooj cua zaus receiver thiab lwm yam teb. Nws muaj peev xwm sib xyaw cov cim ntawm ntau zaus ua ke, tso cai rau lawv kom xa thiab ua tiav ntawm ntau zaus bands.
2. Cov khoom siv xov tooj cua: Hauv cov khoom siv xov tooj cua, cov khoom sib xyaw sib npaug tuaj yeem siv rau kev hloov kho thiab demodulation ntawm cov teeb liab tau txais thiab xa. Nws muaj peev xwm sib xyaw cov teeb liab tau txais ua ke los tsim cov teeb liab baseband, lossis sib xyaw cov teeb liab baseband ua ke los tsim cov teeb liab modulated.
3. Cov kab ke sib txuas lus hauv av thiab satellite: Cov khoom sib xyaw ua ke ntawm xov tooj cua zaus yog siv dav hauv cov kab ke sib txuas lus hauv av thiab satellite rau kev hloov pauv band, cov khoom siv zaus, cov teeb liab thiab cov khoom sib tov.
4. Lub kaw lus radar: Hauv lub kaw lus radar, lub millimeter wave balanced mixer siv tau rau Doppler velocity measurement, frequency conversion, pulse compression thiab lwm yam txheej txheem ua haujlwm.
5. Cov cuab yeej ntsuas thiab ntsuas: Cov khoom sib xyaw ua ke coaxial kuj tseem siv tau rau hauv cov cuab yeej ntsuas thiab ntsuas rau kev tshuaj xyuas teeb liab, kev hloov pauv zaus, kev tshuaj xyuas spectrum thiab lwm yam kev siv los muab cov txiaj ntsig ntsuas tseeb thiab txhim khu kev qha.

Qualwavemuab cov khoom siv uas tsis tshua muaj kev poob qis thiab cov khoom sib xyaw ua ke siab hauv ntau qhov ntau ntawm 1MHz txog 110GHz. Peb cov khoom sib xyaw siv dav hauv ntau thaj chaw.
