Zaus Xov Tooj Cua(RF) thev naus laus zis yog thev naus laus zis sib txuas lus wireless, feem ntau yog siv hauv xov tooj cua, kev sib txuas lus, radar, kev tswj chaw taws teeb, wireless sensor networks thiab lwm yam teb. Lub hauv paus ntsiab lus ntawm wireless xov tooj cua zaus thev naus laus zis yog raws li kev nthuav dav thiab kev hloov kho thiab demodulation thev naus laus zis ntawm electromagnetic nthwv dej. Hauv qab no kuv yuav qhia koj txog lub hauv paus ntsiab lus ntawm wireless xov tooj cua zaus thev naus laus zis.
Cov ntsiab cai ntawm kev siv tshuab
Kev siv tshuab xov tooj cua wireless yog ib qho thev naus laus zis uas siv cov nthwv dej xov tooj cua rau kev sib txuas lus. Cov nthwv dej xov tooj cua yog ib hom nthwv dej electromagnetic nrog cov zaus thiab ntau yam tshwj xeeb. Hauv kev sib txuas lus xov tooj cua wireless, qhov kawg xa tawm hloov cov teeb liab xov xwm mus rau hauv cov teeb liab electromagnetic los ntawm cov nthwv dej xov tooj cua thiab xa lawv tawm. Qhov kawg tau txais txais cov teeb liab electromagnetic thiab tom qab ntawd hloov lawv mus rau hauv cov teeb liab xov xwm kom ua tiav kev xa cov ntaub ntawv thiab kev sib txuas lus.
Lub hauv paus ntsiab lus ntawm kev txais thiab xa xov tooj cua zaus
Cov ntsiab cai ntawm kev siv tshuab wireless radio frequency feem ntau suav nrog cov hauv qab no:
Kev hloov kho zausHauv kev sib txuas lus hauv xov tooj cua wireless, cov teeb liab xov xwm raug hloov mus ua cov teeb liab electromagnetic wave ntawm cov zaus tshwj xeeb raws li kev siv tshuab modulation. Cov txheej txheem sib xyaw ua ke suav nrog amplitude modulation blending (AM), frequency modulation blending (FM), thiab phase modulation blending (PM).
Kav hlau txais xov: Kav hlau txais xovyog ib qho tseem ceeb hauv kev sib txuas lus hauv xov tooj cua wireless. Nws yog siv los xa thiab txais cov teeb liab xov tooj cua. Kev tsim thiab kev tso cov antennas cuam tshuam rau qhov deb ntawm kev xa xov thiab qhov zoo ntawm kev sib txuas lus wireless.
Lub kav hlau txais xov tooj cua Broadband (1-18GHz)
Tus Qauv Nce Horn Antenna (4.90-7.05GHz)
Conical Dual Polarized Horn Antenna (2-18GHz)
RF Misocov lus qhia txog cov khoom siv antenna
Kev siv channel coding thiab decodingHauv kev sib txuas lus hauv xov tooj cua wireless, kev siv tshuab coding thiab decoding channel yog siv los txhim kho kev ruaj khov thiab kev tiv thaiv kev cuam tshuam ntawm kev sib txuas lus thiab xyuas kom meej qhov tseeb ntawm kev sib txuas lus ntawm cov ntaub ntawv.
Kev tswj hwm hluav taws xob: Kev sib txuas lus hauv xov tooj cua wireless yuav tsum tau kho lub zog thawb kom ntseeg tau tias lub teeb liab tuaj yeem xa mus rau hauv qee qhov ntau thiab tiv thaiv nws kom tsis txhob cuam tshuam rau lwm tus.
Kev tswj hwm zausKev sib txuas lus zaus xov tooj cua wireless yuav tsum tswj hwm cov peev txheej spectrum kom zoo kom tsis txhob muaj kev cuam tshuam ntawm cov peev txheej zaus band pov tseg thiab xyuas kom meej tias kev sib txuas lus ruaj khov thiab kev ntseeg tau.
Cov xwm txheej ntawm daim ntawv thov
Cov thev naus laus zis wireless radio frequency siv dav hauv zej zog niaj hnub no, muab ntau yam kev yooj yim thiab kev tsim kho tshiab rau tib neeg lub neej thiab kev ua haujlwm. Nov yog qee qhov chaw siv wireless RF:
Kev sib txuas lus ntawm tesLub hauv paus ntawm kev sib txuas lus ntawm tes yog thev naus laus zis siv zaus xov tooj cua, suav nrog xov tooj ntawm tes, wireless networks, satellite kev sib txuas lus, thiab lwm yam. Cov khoom siv ntse no tso cai rau tib neeg hu xov tooj, xa cov lus ntawv, thiab nkag mus rau hauv Is Taws Nem txhua lub sijhawm thiab txhua qhov chaw.
Tsev ntseHauv cov tshuab hauv tsev ntse, xws li lub qhov rooj xauv ntse, kev tswj teeb pom kev zoo ntse, cov khoom siv hauv tsev ntse, thiab lwm yam, kev tswj chaw taws teeb thiab kev tswj hwm ntse tuaj yeem ua tiav los ntawm kev siv tshuab wireless.
Internet ntawm Tej YamKev siv tshuab hluav taws xob tsis siv xov tooj cua yog ib feem tseem ceeb ntawm Is Taws Nem ntawm Yam. Nws ua tiav kev sib txuas ntawm cov khoom siv los ntawm cov tes hauj lwm sensor wireless thiab ua tiav kev saib xyuas ntse, kev sau cov ntaub ntawv thiab kev tswj chaw taws teeb.
Wireless sensor networkHauv cov tes hauj lwm wireless sensor, nws yog siv rau hauv kev saib xyuas ib puag ncig, kev kho mob, kev tswj hwm kev lag luam thiab lwm yam teb kom ua tiav cov ntaub ntawv sau thiab kev saib xyuas tiag tiag.
Cov khoom siv tswj chaw taws teeb wireless: Cov thev naus laus zis wireless xov tooj cua siv dav hauv cov vaj huam sib luag tswj xws li TV chaw taws teeb tswj, tsheb tswj, thiab qauv tswj kom ua tiav cov haujlwm chaw taws teeb.
Lub kaw lus radar: Xov tooj cuaKev siv tshuab zaus ua lub luag haujlwm tseem ceeb hauv cov kab ke radar thiab siv rau kev nrhiav lub hom phiaj, taug qab thiab kev taw qhia. Nws yog siv dav hauv aerospace, meteorology thiab lwm yam teb.
Cov ntawv thov ntawm cov thev naus laus zis wireless xov tooj cua yog dav heev, npog ntau qhov chaw, xws li kev sib txuas lus mobile, kev sib txuas lus satellite, radar systems, chaw taws teeb tswj, wireless sensor networks, thiab lwm yam. Nrog rau kev txhim kho tas mus li ntawm thev naus laus zis, wireless xov tooj cua zaus thev naus laus zis yuav txuas ntxiv ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw, coj kev yooj yim dua thiab kev tsim kho tshiab rau tib neeg lub neej thiab kev ua haujlwm.
