    Thaiv Downconverters (LNBs)

    Hauv kev sib txuas lus, txhawm rau pab txhawb kev sib kis ntawm cov teeb liab thiab ua tiav cov kev siv channel, qhov zaus ntawm cov teeb liab kis tau zoo heev, yog li kev hloov pauv zaus ntawm cov teeb liab yog qhov tseem ceeb ntawm kev tshawb fawb kev sib txuas lus. Raws li qhov xwm txheej ua ntej thiab tom qab kev hloov pauv ntau zaus, nws tuaj yeem muab faib ua kev hloov pauv (ntau zaus txo) thiab nce kev hloov pauv (ntau zaus).
    Nyob rau hauv lub receiver, yog hais tias qhov nruab nrab zaus teeb liab tau txais tom qab sib tov yog qis dua qhov qub teeb liab, ces qhov kev sib xyaw no hu ua block downconverters (LNBs).
    Tus txheej txheem ntawm thaiv downconverters yog muab cov teeb liab tau txais nrog lub teeb liab oscillator hauv zos uas tsim los ntawm lub zos oscillator, thiab tom qab ntawd tau txais cov teeb liab hloov dua siab tshiab los ntawm cov lim dej qis. Ob lub teeb liab sib npaug tuaj yeem muab faib ua qhov sib xyaw tiag tiag thiab sib xyaw ua ke los ntawm kev sawv cev tiag tiag lossis nyuaj.
    Lub hom phiaj ntawm block downconverters yog txo cov cab kuj zaus ntawm lub teeb liab los yog ncaj qha tshem tawm cov cab kuj zaus kom tau txais cov teeb liab baseband. Vim nws qhov yooj yim Circuit Court thiab tus nqi qis, txoj kev hloov pauv qis yog siv dav hauv cov cuab yeej siv pej xeem thiab cov khoom siv tub rog nrog kev ua haujlwm tsawg.

    Daim ntawv thov:

    1. Satellite TV: LNBs yog cov khoom tseem ceeb hauv satellite TV txais tos. Lawv tau nruab rau ntawm qhov chaw focal ntawm lub kav hlau txais xov satellite (paraboloid lossis phaj), tau txais lub teeb liab TV xa los ntawm satellite, thiab hloov mus rau hauv lub teeb liab nruab nrab zaus uas tuaj yeem ua tiav los ntawm tus txais.
    2. Satellite Internet: Hauv satellite Internet systems, LNBs yog siv los txais Internet cov ntaub ntawv xa los ntawm satellites. Cov cuab yeej siv tau txais cov ntaub ntawv los ntawm LNB thiab txiav txim siab thiab ua haujlwm los ntawm modem.
    3. Kev sib txuas lus satellite: LNBs tau siv dav hauv ntau lub xov tooj cua sib txuas lus, suav nrog xov tooj cua satellite, xov tooj cua tshaj tawm, xov tooj cua xa xov tooj cua, thiab lwm yam. Lawv pab tau txais thiab ua tiav ntau hom kev sib txuas lus xa los ntawm satellites.
    4. Kev Saib Xyuas Lub Ntiaj Teb thiab Kev Tshawb Fawb Txog Kev Tshawb Fawb: Hauv qee qhov kev soj ntsuam lub ntiaj teb thiab cov ntawv thov kev paub txog thaj chaw deb, LNBs tau siv los txais cov ntaub ntawv xa mus rau cov chaw taws teeb ntawm satellites. Cov ntaub ntawv no tuaj yeem siv rau hauv kev saib xyuas huab cua, kev saib xyuas ib puag ncig, ceeb toom kev puas tsuaj thiab lwm yam haujlwm.
    Hauv cov ntsiab lus, LNBs ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus satellite niaj hnub no thiab tau siv dav hauv kev tshaj tawm hauv TV, kev siv Internet, kev sib txuas lus cov ntaub ntawv thiab ntau yam kev tshaj lij.

    Qualwavemuab ntau hom Block Downconverters (LNBs) hauv S~Ka-Band, nrog lub suab nrov ntawm 45 ~ 240K. Qhov kev txiav txim nrog ntau hom kom tau raws li cov neeg siv khoom xav tau.
