Nyob rau hauv niaj hnub satellite kev sib txuas lus systems, RF Cheebtsam yog lub luag hauj lwm rau lub luag hauj lwm tseem ceeb ntawm cov ntaub ntawv kis tau tus mob thiab teeb liab ua. Nrog rau kev siv dav dav ntawm siab - kev sib txuas lus satellite zaus, RF systems tsim cov kev cai nruj ntxiv rau cov khoom siv hluav taws xob. Ua ntej, siab -frequency transmission stability tau dhau los ua ib qho kev ntsuas tseem ceeb. Hauv kev sib txuas satellite, raws li cov teeb liab zaus nce ntxiv, txawm tias qhov hloov pauv me me hauv cov yam ntxwv ntawm tus neeg xyuas pib tuaj yeem ua rau kis tau tus kab mob lossis theem hloov pauv, ua rau nws tseem ceeb rau cov neeg siv hluav taws xob kom muaj kev ruaj ntseg hluav taws xob thoob plaws tag nrho cov zaus. Nyob rau tib lub sijhawm, kev ua haujlwm qis- poob qis tau dhau los ua qhov tseem ceeb, tshwj xeeb tshaj yog nyob rau hauv ntev - nrug thiab ntau- plhaw kev sib txuas lus, qhov twg txhua feem ntawm lub zog poob tuaj yeem cuam tshuam tag nrho cov teeb liab zoo. Tsis tas li ntawd, thermal stability yog lwm yam tseem ceeb uas txiav txim siab tus neeg xyuas pib kev ntseeg tau. RF Cheebtsam ua haujlwm hauv lub tshuab hluav taws xob lossis lub tshuab hluav taws xob microwave ua rau muaj kev hloov pauv ntawm qhov kub thiab txias, yog li cov neeg siv hluav taws xob yuav tsum muaj kev ruaj ntseg ntawm cov qauv thiab hluav taws xob nyob rau hauv siab - qhov kub thiab txias los xyuas kom meej tias tag nrho cov kab ke txuas ntxiv ua haujlwm tau zoo nyob rau hauv cov xwm txheej nyuaj.
Kub coated molybdenum hlauua kom pom qhov zoo tshwj xeeb raws li cov cai nruj no. Lub molybdenum substrate nws tus kheej muaj qhov siab melting point thiab thermal stability zoo heev, uas tso cai rau nws kom muaj kev ruaj ntseg thiab ruaj khov txawm nyob rau hauv qhov kub thiab txias los yog nquag thermal cycling, zoo tiv thaiv distortion ntawm RF signals. Lub caij no, cov txheej kub kub muab cov khoom siv hluav taws xob zoo tshaj plaws thiab kev tiv thaiv oxidation, kom ntseeg tau siab -kev ncaj ncees ntawm cov hluav taws xob xaim hluav taws xob thaum txuas lub neej kev pab cuam ntawm cov khoom. Qhov tseem ceeb, cov qauv sib xyaw ntawm molybdenum substrate nrog cov txheej kub ua kom pom cov yam ntxwv zoo sib xws hauv siab - zaus teeb liab kis tau tus mob, txo cov kab mob parasitic capacitance thiab kev sib txuas sib txuas, yog li txhim kho kev ruaj ntseg thiab kev ntseeg siab ntawm tag nrho RF txuas.
Cov khoom zoo li no tshwj xeeb tshaj yog tshwm sim hauv kev siv tswv yim.Kub coated molybdenum hlauyog dav siv nyob rau hauv lub hwj chim amplifiers thiab microwave modules, tuav lub meej kis tau tus mob ntawm ilv teeb liab. Nyob rau hauv lub hwj chim amplifiers, nws muaj peev xwm nyob ruaj khov tam sim no nyob rau hauv high-power density tej yam kev mob thaum lub sij hawm kom ntseeg tau raws li cov ntsiab lus sib cuag thiab cov yam ntxwv impedance tsawg, tso cai rau lub amplifier tso zis siab - zoo teeb liab yam tsis tau qhia ntxiv suab nrov. Nyob rau hauv lub microwave modules, nws raug xa mus rau siab -frequency signals, tswj lub teeb liab kev ncaj ncees nyob rau hauv ib tug dav zaus band, uas yog ib qho tseem ceeb rau tag nrho cov kev ua tau zoo ntawm satellite kev sib txuas lus txuas. Txawm hais tias nyob rau hauv cov chaw nres tsheb hauv av lossis satellite terminals, kub coated molybdenum hlau tau dhau los ua cov khoom tseem ceeb rau kev ua haujlwm ruaj khov ntawm RF cov khoom.
Raws li qhov tshwm sim, kub coated molybdenum hlau muaj qhov cuam tshuam loj rau kev ntseeg tau ntawm lub cev thiab teeb liab kev ncaj ncees. Nws tuaj yeem txo cov teeb liab poob thiab cuam tshuam txog kev cuam tshuam hauv RF txuas thiab txo qhov kev hloov pauv ntawm kev ua haujlwm los ntawm thermal drift, kom ntseeg tau tias lub kaw lus muaj kev ruaj ntseg siab ntev - lub sijhawm ua haujlwm. Kev ua haujlwm ruaj khov ntawm tus neeg xyuas pib tsis yog tsuas yog txhim kho kev ntseeg tau ntawm cov ntaub ntawv xa mus, tab sis kuj muab lub hauv paus ruaj khov rau kev sib txuas lus meej hauv cov xwm txheej nyuaj. Nrog satellite kev sib txuas lus thev naus laus zis nce mus rau ntau zaus thiab dav bandwidths, tus nqi ntawm kub coated molybdenum hlau ua qhov tseem ceeb. Nws cov thermal stability, zoo heev conductivity, thiab muaj peev xwm los xyuas kom meej siab -frequency kev ua tau zoo muaj ntau dua saj zawg zog thiab kev ntseeg siab nyob rau hauv lub system tsim.
Saib tom ntej, kev txhim kho ntawm siab - zaus satellite kev sib txuas lus yuav txuas ntxiv tsav kev tsim kho tshiab hauv RF cov khoom siv. Raws li Ka-band, V-band, thiab ntau dua - cov ntawv thov zaus ua ntau dua, cov kev xav tau siab dua tau muab tso rau ntawm cov neeg siv hluav taws xob rau qis- poob, siab thermal stability, thiab siab - zaus ua haujlwm. Kub coated molybdenum hlau, nrog nws cov khoom tshwj xeeb cov qauv zoo, yog zoo - haum rau ua tau raws li cov kev cov nyom, txhawb RF modules yav tom ntej nyob rau hauv kev ua tau zoo siab -precision, siab -cov ntaub ntawv ua tau zoo nyob rau hauv cov huab cua. Tsis tas li ntawd, raws li satellite systems txuas ntxiv mus rau lub teeb yuag thiab kev sib xyaw ua ke zoo heev, daim ntawv thov muaj peev xwm ntawm kub coated molybdenum hlau nyob rau hauv cov khoom ntim me me thiab qhov tseeb yuav nthuav dav ntxiv, muab kev txhawb nqa rau siab - kev ntseeg siab, siab - kev sib txuas lus satellite.
Nyob rau hauv cov ntsiab lus, kub coated molybdenum hlau, nrog rau nws zoo thermal stability, superior conductivity, thiab siab - zaus kis tau tus mob zoo, tau dhau los ua ib tug indispensable core khoom nyob rau hauv satellite kev sib txuas lus RF Cheebtsam. Nyob rau hauv lub hwj chim amplifiers thiab microwave modules, nws tsis tsuas yog ua kom lub teeb liab kev ncaj ncees thiab kev cia siab ntawm lub system tab sis kuj nteg lub hauv paus ruaj khov rau txoj kev loj hlob ntawm yav tom ntej high - zaus satellite kev sib txuas lus. Raws li kev sib txuas lus thev naus laus zis txuas ntxiv mus ntxiv, daim ntawv thov tus nqi ntawm cov kub coated molybdenum hlau yuav dhau los ua qhov tseem ceeb, muab kev txhawb nqa tseem ceeb rau kev ua haujlwm ruaj khov ntawm siab -kev ua haujlwm satellite kev sib txuas lus.
Txhawm rau txhim kho kev ua tau zoo thiab kev ntseeg siab ntawm koj cov kev sib txuas lus satellite, peb muab peb tus kheejkub coated molybdenum hlaucov kab ntau lawm, uas tso cai rau peb txo qis cov sij hawm txhuas thiab muab kev hloov kho tau yooj yim raws li kev ua lag luam thiab cov neeg siv khoom xav tau. Peb tuaj yeem kho ob qho tib si cov tub ntxhais hlau (cov khoom siv hauv paus) thiab cov khoom siv txheej, thiab txoj kab uas hla ntawm cov hlau xaim tuaj yeem raug kho raws li koj qhov tshwj xeeb.
