Raws li lub ntiaj teb satellite hauv av chaw nres tsheb cov khoom lag luam nce mus txog qhov ntsuas ntawm $ 12.71 nphom hauv xyoo 2024, ib hom tshiab ntawm SAT-IF optical receiver tau dhau los ua qhov tseem ceeb hauv kev lag luam.
Tsis ntev los no, kev siv thev naus laus zis tau tshwm sim hauv thaj chaw ntawm kev sib txuas lus satellite - lub SAT-IF optical receiveryog qhov tseem ceeb txhim kho qhov kev sib kis tau zoo thiab zoo ntawm cov teeb liab satellite los ntawm kev tsim qauv zoo heev. Cov cuab yeej no tuaj yeem hloov pauv tag nrho L-Band analog satellite signals (SAT-IF) tau txais los ntawm lub kav hlau txais xov satellite LNB rau hauv cov teeb liab kho qhov muag, ua kom pom tseeb, siab - zoo, ntev- kis tau tus mob hla optical fiber.
01 Technical Principple: Qhov Txuas Txuas ntawm Optoelectronic Conversion
SAT-IF optical receiver plays lub luag haujlwm tseem ceeb hauv kev sib txuas lus satellite, ua raws li cov khoom siv tseem ceeb rau cov teeb liab thaum sib kis ntawm satellite mus rau hauv av chaw nres tsheb.
Traditional receiver architectures feem ntau siv cov qauv superheterodyne. RF input teeb liab thawj zaug dhau los ntawm RF lim, tom qab ntawd los ntawm Tsawg-Noise Amplifier (LNA).
Tom qab ntawd, lub teeb liab sib xyaw nrog lub tunable LO input nyob rau hauv lub tov khoom, hloov mus rau ib qho Intermediate Frequency (IF) band.
Hauv qhov sib piv, SAT tshiab -IF optical receiver txais kev ncaj qha down- hloov dua siab tshiab architecture, siv ob khub ntawm cov neeg txais kev sib npaug thiab qhov kho qhov muag 90-degree hybrid los ua optical I/Q nrhiav.
Qhov kev siv thev naus laus zis no tso cai rau lub cuab yeej ua haujlwm dhau ntawm ntau zaus ntawm 950 ~ 2600MHz, npog yuav luag tag nrho cov analog satellite teeb liab hauv L-Band.
Photodetectors hloov lub teeb rau hauv hluav taws xob los ntawm cov nyhuv photoelectric, uas yog lub hauv paus ntsiab lus ua haujlwm ntawm optical receivers. Tsim los ntawm qhov no, lubSAT-IF optical receiverua kom siab -fidelity teeb liab kis tau los ntawm zoo linearity thiab flatness.
02 Kev Ua Tau Zoo Zoo: Ntau Qhov Kev Txhim Kho Tshiab
SAT-IF optical receiver qhia tau hais tias muaj ntau yam kev ua tau zoo. Ua ib qho khoom lag luam ntawm kev ua lag luam ua piv txwv, nws muaj ntau yam khoom siv hluav taws xob kho qhov muag txais lub peev xwm ntawm -18 txog +3 dBm.
Qhov kev tawm tswv yim dav dav no tso cai rau lub cuab yeej hloov kho rau cov tswv yim tawm tswv yim ntawm qhov sib txawv ntawm qhov muaj zog, ua kom muaj kev ruaj ntseg hauv ntau qhov chaw.
Hais txog RF tsis, SAT-IF optical receiver tuaj yeem ua haujlwm nyob rau hauv ntau zaus ntawm 45 ~ 2150MHz, ua tiav qib siab ntawm ± 1 dB.
Qhov no txhais tau hais tias lub cuab yeej teb rau cov teeb liab ntawm cov zaus sib txawv yog qhov zoo sib xws thoob plaws tag nrho cov kev khiav hauj lwm band, tsis muaj qhov hloov pauv loj.
Cov cuab yeej boasts tus Carrier -rau-Noise Ratio (CNR) Ntau dua lossis sib npaug li 50 dB, Composite Second Order (CSO) Ntau dua lossis sib npaug li 65 dB, thiab Composite Triple Beat (CTB) Ntau dua lossis sib npaug rau 62 dB. Peb qhov ntsuas no yog qhov tseem ceeb rau kev ua kom lub teeb pom kev zoo, nrog rau qhov muaj txiaj ntsig zoo lav lub teeb liab siab ncaj ncees thaum sib kis.
SAT-IF optical receiver kuj siv GaAs amplifier active li thiab ultra-tso suab nrov technology, txo cov suab nrov tau qhia thaum lub teeb liab ua thiab txhim kho teeb liab purity.
03 Daim Ntawv Thov Scenario: Los ntawm Triple-Kev Ua Si Kev Sib Txuas rau Maritime Communication
SAT-IF optical receiver qhia nws tus nqi tshwj xeeb hauv ntau qhov xwm txheej.
Triple-kev ua si kev koom ua ke yog ib qho tseem ceeb ntawm daim ntawv thov. Zhuhai Jiesheng Electronic Technology Co., Ltd. tau tsim tshwj xeeb rau SAT-IF optical receiver rau FTTH (Fiber To The Home) tes hauj lwm rau lub hom phiaj no.
Nws txhawb kev khiav hauj lwm zaus ntawm 45-1000MHz, 45-2150MHz, thiab 45-2400MHz, ua tau raws li cov kev xav tau rau ib txhij xa cov ntaub ntawv, suab, thiab video signals.
Hauv satellite L-Band uplink/downlink fiber optic txuas, cov khoom siv no muab kev lag luam qis tshaj - cov nqi daws.
FWT/R–2600S series cov khoom lag luam los ntawm Hangzhou Fengrui Optoelectronic Equipment Co., Ltd. tuaj yeem xa tag nrho cov teeb liab analog satellite hauv L-Band, muab cov neeg ua haujlwm hauv network nrog siab- zoo, ntev- kis tau tus mob kev daws teeb meem.
Maritime satellite fiber optic faib tshuab kuj tau txais txiaj ntsig los ntawm cov thev naus laus zis no. Thaum caij nkoj hauv hiav txwv, cov nkoj tuaj yeem ruaj khov tau txais cov teeb liab satellite thiab xa tawm ntawm fiber ntau optics rau ntau qhov kev siv los ntawm SAT-IF optical receiver.
Tsis tas li ntawd, satellite L-Band fiber optic lub tsev faib tshuab sawv cev rau lwm qhov kev thov tseem ceeb rau SAT-IF optical receiver. Hauv cov tsev loj loj, faib cov teeb liab satellite ntawm fiber ntau optics tuaj yeem zam teeb meem teeb meem kev cuam tshuam uas tshwm sim hauv ib txwm siv tooj liab cable kis tau tus mob.
04 Kev Ua Lag Luam Zej Zog: Nkag mus rau Lub Sijhawm Kev Loj Hlob
Raws li kev txheeb xyuas kev lag luam, lub ntiaj teb satellite hauv av chaw nres tsheb khoom lag luam tau nkag mus rau lub sijhawm ntawm kev loj hlob sai. Kev lag luam loj txog $ 12.71 nphom hauv 2024 thiab xav tias yuav ncav cuag $ 13.33 nphom los ntawm 2025.
Los ntawm 2033, lub ntiaj teb satellite hauv av chaw nres tsheb cov khoom lag luam tau kwv yees kom ncav cuag $ 19.55 nphom, nrog rau Compound Annual Growth Rate (CAGR) ntawm 4.9% thaum lub sijhawm xyoo 2025 txog 2033.
Ntau yam ua rau muaj kev xav tau ntau ntxivSAT-IF optical receivers. Cov no suav nrog kev thov nce ntxiv rau Ku thiab Ka-band satellites, thiab kev siv tsheb loj zuj zus hauv kev ua tub rog thiab kev lag luam.
Hauv xyoo 2024, ntau dua 4,500 lub chaw ua haujlwm satellite tau tsim kom muaj kev xav tau ntau ntxiv rau cov chaw nres tsheb hauv av.
Kev tsim kho thev naus laus zis kuj tseem yog qhov tseem ceeb ua rau kev lag luam loj hlob. Piv rau Fixed Satellite Systems, HTS (High Throughput Satellite) tshuab tuaj yeem siv tib zaus hauv orbit.
Cov satellites feem ntau yog siv los muab kev pabcuam broadband internet rau cov cheeb tsam uas tsis tshua muaj kev sib txuas lossis tsis tau tsim.
Hais txog kev faib khoom hauv cheeb tsam, North America suav txog ntau dua 35% ntawm cov chaw thoob ntiaj teb hauv 2024, coj los ntawm NASA thiab cov tuam txhab ntiag tug xws li SpaceX thiab Amazon Kuiper.
Asia- cheeb tsam Pacific tseem tab tom muaj kev loj hlob sai, raws li muaj pov thawj los ntawm kev sib koom tes ntawm Sivers Semiconductors thiab South Kauslim Lub Tuam Txhab Doosan.
05 Kev Txhim Kho Kev Lag Luam: Kev Sib Koom Tes Ua Tau Zoo Tshaj Plaws
Tawm tsam qhov kev lag luam tawm tshiab no, cov tuam txhab loj tau nquag mus nrhiav cov tswv yim layouts.
Sivers Semiconductors thiab Doosan Tuam Txhab tsis ntev los no tshaj tawm kev sib koom tes los tsim Ka-band Electronically Steerable Array (ESA) panels rau Satellite Communication (SATCOM).
Qhov kev sib koom tes no, muaj nuj nqis ntawm $ 1.5 lab, yuav pab nyiaj rau kev tsim thiab txhim kho cov kav hlau txais xov siab heev uas siv los ntawm Sivers 'kev lag luam dav dav Ka-band SATCOM Beamforming Integrated Circuit (BFIC).
Qhov kev sib koom tes no yog lub sijhawm tseem ceeb rau Sivers hauv kev nthuav dav nws cov hneev taw hauv ntiaj teb SATCOM kev ua lag luam.
Nyob rau hauv lub teb ntawm SAT-IF optical receiver khoom, Suav tuam txhab uas muag xws li Hangzhou Fengrui Optoelectronic Equipment Co., Ltd. thiab Zhuhai Jiesheng Electronic Technology Co., Ltd. twb tau pib ua lag luam cov khoom.
Zhuhai Jiesheng ElectronicsSAT-IF optical receivernta ib daim ntawv compact (113x57x25mm), hnyav tsuas yog 110g, thiab siv tsawg dua 2W ntawm lub zog. Cov qauv tsim compact no yooj yim rau kev teeb tsa yooj yim dua thiab tseem txo qis kev siv zog.
Cov neeg ua si thoob ntiaj teb xws li Gilat Satellite Networks thiab Hughes Network Systems kuj tseem ua haujlwm rau lawv tus kheej hauv daim teb no.
Hughes Network Systems tau ua tiav kev sim 5G satellites los ntawm nws Jupiter system hauv av hauv lub Rau Hli 2022.
Qhov kev txhim kho no tau lees paub qhov kev siv thev naus laus zis sib raug zoo nrog 5G Qhib Xov Tooj Cua Access systems, qhib qhov muaj peev xwm rau kev koom ua ke ntawm SAT-IF optical receivers nrog 5G networks.
Kev sib tw hauv kev lag luam kev sib txuas lus satellite txuas ntxiv los ntawm qhov chaw mus rau hauv av. Raws li kev sib koom tes thoob ntiaj teb zoo li ib qho ntawm Sivers thiab Doosan sib sib zog nqus, cov thev naus laus zis tshiab xws li Ka-band ESA panels yuav ua lag luam sai.
Nyob rau xyoo tom ntej, daim ntawv thov SAT-IF optical receivers yuav nthuav dav los ntawm cov chaw tshwj xeeb mus rau cov xwm txheej pej xeem dav dav, dhau los ua ib qho tseem ceeb hauv kev sib txuas qhov chaw sib koom ua ke- huab cua- hauv av.
