Kev lag luam Low Noise Block (LNB) tab tom muaj kev nce siab heev hauv kev lag luam khoom siv hluav taws xob rau cov neeg siv khoom. Raws li Verified Market Reports, kev lag luam LNB muaj nqis txog $ 1.5 billion hauv xyoo 2022 thiab kwv yees tias yuav ncav cuag $ 2.3 billion los ntawm xyoo 2030. Kev loj hlob no yog tsav los ntawm kev thov nce ntxiv rau cov ntsiab lus siab thiab kev nthuav dav ntawm Direct-to-Home (DTH) cov kev pabcuam. Lub Koom Haum Thoob Ntiaj Teb Telecommunication (ITU) kwv yees tias kev sau npe satellite thoob ntiaj teb yuav tshaj 350 lab los ntawm xyoo 2025, qhia txog lub peev xwm muaj zog rau LNBs hauv xyoo tom ntej.
Kev nce qib thev naus laus zis yog qhov tseem ceeb uas ua rau kev lag luam LNB loj hlob. Cov tuam txhab niaj hnub no txhim kho LNBs kom tau raws li qhov xav tau ntawm kev lag luam khoom siv hluav taws xob. Piv txwv li, Diodes nyuam qhuav tsim cov ICs tswj hwm thiab tswj hwm LNB uas muaj zog tsawg, suab nrov tsawg. Cov ICs no yog tsim los rau ntau yam khoom, suav nrog cov thawv teeb tsa, cov TV nrog cov tuners satellite uas ua rau hauv, thiab cov npav tuner satellite hauv computer. Lawv muab kev ua haujlwm zoo dua thiab kev ntseeg siab, uas yog qhov tseem ceeb rau cov khoom siv hluav taws xob niaj hnub no.
Kev lag luam LNB muaj ntau yam khoom sib txawv uas ua tau raws li cov neeg siv xav tau sib txawv. Cov no suav nrog ib qho LNB, ob qho, thiab plaub qhov. Txhua hom yog tsim los kom ua tau raws li cov kev xav tau tshwj xeeb, xws li lub zog teeb liab thiab ntau zaus. Qhov kev sib txawv no tso cai rau cov chaw tsim khoom muab cov kev daws teeb meem rau ntau yam kev siv, los ntawm TV satellite hauv tsev mus rau kev sib txuas lus satellite lag luam.
Hauv cheeb tsam, kev lag luam LNB kuj pom kev hloov pauv ntau yam. North America tam sim no tab tom muaj kev loj hlob siab tshaj plaws. Txawm li cas los xij, cov lag luam tshiab hauv Asia thiab lwm thaj chaw kuj tseem muaj peev xwm loj hlob. Kev loj hlob hauv cov cheeb tsam no yog tsav los ntawm kev nce ntxiv ntawm kev teeb tsa lub tais satellite thiab kev siv cov thev naus laus zis sib txuas lus satellite siab heev.
Muaj ntau lub tuam txhab uas tswj hwm kev lag luam LNB. Microelectronics Technology Inc. (MTI), Zhejiang Shengyang, thiab Norsat yog cov tuam txhab ua si saum toj kawg nkaus. Cov tuam txhab no muab ntau yam khoom LNB thiab pheej nqis peev rau kev tshawb fawb thiab kev txhim kho kom nyob ua ntej hauv kev sib tw. Piv txwv li, MTI tsim thiab muag ntau yam khoom microwave IC rau kev tshaj tawm satellite, kev sib txuas lus, thiab kev sib txuas lus.
Saib mus tom ntej, kev ua lag luam LNB tau npaj txhij rau kev nthuav dav ntxiv. Kev koom ua ke ntawm IoT thiab 5G kev sib txuas yuav tsim cov cib fim tshiab rau LNBs hauv kev lag luam khoom siv hluav taws xob. Raws li thev naus laus zis satellite txuas ntxiv mus, qhov kev thov rau LNBs ua tau zoo yuav nce ntxiv. Qhov no yuav tsav cov tuam txhab tsim khoom kom tsim kho tshiab thiab tsim cov kev daws teeb meem LNB zoo dua thiab txhim khu kev qha.
