Los ntawm cov xov tooj ntse mus rau cov kev pabcuam satellite thiab GPS RF thev naus laus zis yog qhov tshwj xeeb ntawm lub neej niaj hnub.Nws yog ubiquitous uas ntau ntawm peb tau txais nws rau kev tso cai.
RF engineering txuas ntxiv tsav lub ntiaj teb kev txhim kho hauv ntau daim ntawv thov hauv pej xeem thiab ntiag tug.Tab sis kev txhim kho thev naus laus zis tau nrawm heev uas qee zaum nyuaj rau twv seb lub ntiaj teb yuav zoo li cas hauv ob peb xyoos.Thaum ntxov li 2000, muaj pes tsawg tus neeg sab hauv thiab sab nraud kev lag luam yuav kwv yees tias lawv yuav saib streaming video ntawm lawv lub xov tooj ntawm tes hauv 10 xyoo?
Kuj ceeb tias, peb tau ua qhov kev vam meej zoo li no hauv lub sijhawm luv luv, thiab tsis muaj lub cim ntawm kev qeeb qeeb ntawm qhov kev thov rau RF technology siab heev.Cov tuam txhab ntiag tug, tsoomfwv thiab cov tub rog thoob ntiaj teb tab tom sib tw kom muaj qhov tshiab RF tshiab.
Hauv tsab xov xwm no, peb yuav teb cov lus nug hauv qab no: Yuav ua li cas RF kev lag luam zoo li hauv kaum xyoo?Tam sim no thiab yav tom ntej yog dab tsi thiab peb yuav ua li cas ua ntej?Peb yuav ua li cas thiaj nrhiav tau cov neeg muag khoom uas pom cov ntawv ntawm phab ntsa thiab paub tias cov khoom mus li cas?
Tom ntej no RF kev lag luam tiam sis thiab yav tom ntej ntawm RF Technology.Yog tias koj tau mob siab rau kev txhim kho hauv RF teb, koj yuav paub tias 5g kiv puag ncig yav tom ntej yog ib qho kev hloov pauv loj tshaj plaws ntawm lub qab ntug.Los ntawm 2027, nws yog qhov tseeb tias peb tuaj yeem cia siab tias 5g network tau pib thiab ua haujlwm rau qee lub sijhawm, thiab cov neeg siv khoom kev cia siab rau lub xov tooj ntawm tes thiab kev ua haujlwm yuav siab dua tam sim no.Raws li ntau thiab ntau tus neeg nyob ib ncig ntawm lub ntiaj teb no siv cov xov tooj ntse, qhov kev thov rau cov ntaub ntawv yuav nce ntxiv, thiab cov tsoos bandwidth hauv qab 6GHz tsuas yog tsis txaus los ua kom tau raws li qhov kev sib tw no.Ib qho ntawm thawj qhov kev sim pej xeem ntawm 5g ua rau muaj qhov nrawm nrawm ntawm 10 GB ib ob ntawm mus txog 73 GHz.Tsis muaj qhov tsis ntseeg tias 5g yuav muab xob laim ceev ceev ntawm cov zaus yav dhau los tsuas yog siv rau kev siv tub rog thiab satellite.
5g network yuav ua lub luag haujlwm tseem ceeb hauv kev sib txuas lus wireless, txhim kho virtual kev muaj tiag thiab txuas ntau lab ntawm cov cuab yeej peb siv niaj hnub no.Nws yuav dhau los ua tus yuam sij qhib IoT.Cov khoom lag luam hauv tsev suav tsis txheeb, cov khoom siv hluav taws xob, cov khoom siv siv tau, cov neeg hlau, cov khoom siv hluav taws xob, thiab cov tsheb autopilot yuav raug txuas los ntawm qhov tsis hnov tsw ntawm network ceev.
Qhov no yog ib feem ntawm qhov Eric Schmidt, tus thawj tswj hwm ntawm cov tsiaj ntawv, Inc, txhais tau hais tias thaum nws thov tias Is Taws Nem raws li peb paub tias nws yuav " ploj mus";Nws yuav dhau los ua qhov dav dav thiab koom ua ke rau txhua yam khoom siv peb siv uas peb tsis tuaj yeem paub qhov txawv ntawm "lub neej tiag".Kev nce qib ntawm RF thev naus laus zis yog cov khawv koob uas ua rau txhua yam no tshwm sim.
Kev siv tub rog, aerospace thiab satellite:
Nyob rau hauv lub ntiaj teb no ntawm kev vam meej technology ceev ceev thiab kev nom kev tswv tsis paub tseeb, qhov yuav tsum tau kom muaj kev ua tub rog superiority muaj zog dua puas tau.Nyob rau yav tom ntej, kev siv hluav taws xob thoob ntiaj teb kev ua tsov rog (EW) yuav tsum tshaj US $ 9.3 nphom los ntawm 2022, thiab qhov kev thov rau tub rog RF thiab microwave technology kev nce qib tsuas yog nce.
Kev vam meej mus tom ntej hauv "kev ua tsov rog hluav taws xob" thev naus laus zis
Kev ua tsov rog hauv hluav taws xob yog "siv hluav taws xob (EM) thiab lub zog taw qhia los tswj cov hluav taws xob hluav taws xob lossis tawm tsam cov yeeb ncuab".(mwrf) cov neeg ua haujlwm tiv thaiv loj yuav koom ua ke ntau dua thiab ntau dua kev ua tsov rog hluav taws xob rau hauv lawv cov khoom hauv kaum xyoo tom ntej.Piv txwv li, Lockheed Martin tus tshiab F-35 fighter muaj kev sib ntaus sib tua hluav taws xob muaj peev xwm, uas tuaj yeem cuam tshuam cov yeeb ncuab ntau zaus thiab tua radar.
Ntau lub tshuab EW tshiab no siv cov khoom siv gallium nitride (GAN) los pab ua kom tau raws li lawv cov kev xav tau ntawm lub zog, nrog rau cov suab nrov qis (LNAs).Tsis tas li ntawd, kev siv cov tsheb tsis muaj neeg tsav tsheb hauv av, hauv huab cua thiab hauv hiav txwv kuj tseem yuav nce ntxiv, thiab cov kev daws teeb meem RF nyuaj yuav tsum tau sib txuas lus thiab tswj cov tshuab no ntawm kev ruaj ntseg network.
Hauv kev ua tub rog thiab kev lag luam, qhov kev thov rau kev sib txuas lus satellite siab tshaj (SATCOM) RF kev daws teeb meem kuj tseem yuav nce ntxiv.SpaceX txoj haujlwm WiFi thoob ntiaj teb yog ib txoj haujlwm tshwj xeeb uas xav tau kev tsim kho RF qib siab.Qhov project yuav xav tau ntau tshaj 4000 hauv orbit satellites xa wireless Internet rau tib neeg thoob plaws ntiaj teb ntawm Ku thiab Ka siv 10-30 GHz zaus - band ntau - qhov no tsuas yog lub tuam txhab!
