Dab tsi yog RF resistor?
Dab tsi yog RF resistor? Tsuas yog muab tso, cov neeg tawm tsam siv hauv RF microwave kev sib txuas lus kev sib txuas lus yog hu ua RF inistors.
Txhua tus yuav tsum paub txog cov xov tooj cua ntsa nrawm tam sim no, uas yog ib lub shorethand rau cov high-zaus hloov hluav taws xob tshiab.
Qhov siab tshaj plaws tam sim no hloov pauv ntau dua 10000 zaug ib qho thib ob yog hu ua xov tooj cua tshaj tawm.
RF resistor yog cov khoom siv passive uas tuaj yeem thaiv cov zaj xov tooj cua hauv xov tooj cua tam sim no. Thiab hloov pauv lub zog hluav taws xob rau hauv tshav kub lossis lwm hom kev siv hluav taws xob, nrog chav ntsuas ntawm Ohms (ω) ua tib yam li cov kev tiv thaiv zoo tib yam.
RF uas tsim tawm feem ntau tau faib raws li lub zog, thiab muaj ntau txoj hauv kev los cais lawv:
Tso cais los ntawm cov qauv sab nraud, nws tuaj yeem faib ua:
1.chip resistor (chip resistors tau muab faib ua ib qho electrode nti tiv taus thiab dual electrode nti resistors)
2.leaded resistor (cov coj los tiv thaiv tau muab faib ua ib qho ua rau cov uas ua rau ib leeg ua rau tus thawj coj thiab ua dual ua resistors)
3.flanged resistor (Flanged resistors tau muab faib ua ib qho kev ua yeeb yaj kiab nrog ib qho txhuas flanged desistors thiab dual flanged resistors)
Raws li cov txheej txheem kev faib tawm ntau lawm, nws tuaj yeem faib ua:
1.Qhov zaj duab xis RF resistor (raug xa mus rau cov tuab fuab zaj duab xis resistor)
2.Qhov zaj duab xis RF resistor (raug xa mus rau cov ntawv zaj duab xis xub ntiag)
Raws li kev faib tawm lub zog, nws tuaj yeem faib ua:
1.Qhov Hwj chim RF resistor (raug xa mus rau cov resistor, feem ntau xa mus rau tsim tawm nrog lub zog ntawm 60W lossis ntau dua)
2.Low Hwj Rawm RF resistor (hais cov tshuaj uas muaj tsawg-hluav taws xob, feem ntau xa mus rau cov zog tiv thaiv hauv qab 20W)
Hais kom qhia los ntawm zaus, nws tuaj yeem faib ua:
1.Qhov zaus zaus Ref resistor (raug xa mus rau cov neeg tiv taus siab, feem ntau tiv thaiv nrog ntau zaus ntau dua 3GHz)
2.Lawv ntau zaus RF resistor (hais tawm raws li cov nquag tiv thaiv, feem ntau tiv thaiv nrog ntau zaus qis dua 3GHz)
Cov ntaub ntawv thiab cov txiaj ntsig zoo thiab qhov tsis zoo rau kev ua RF inistorors:
1.Beryllium oxide (boo) muaj siab thermal conductivity, yuav luag sib npaug Nws loj tshaj plaws qhov tsis zoo yog tias nws yog tshuaj lom hauv cov hmoov hmoov, ua rau nws tsis yooj yim rau kev tiv thaiv txhab kom zoo. Yog li feem ntau, cov manufacturers ntawm RF intistors yuav cov ntaub ntawv cov ntaub ntawv thiab tsis tas yuav ua tiav theem nrab. Qhov no ua rau kev siv binerylium oxide (boo) ua cov rf resistors uas tsuas yog luam tawm ntawm ib qho kev ua tau zoo, txo qis kev ua tau zoo.
2.Thaum cov khoom siv hluav taws xob (ALN) kuj yog cov khoom siv thermal zoo tshaj plaws thiab qib siab dua cov khoom siv zoo dua li txhuas oxide thiab berylylium oxide ceramics. Vim nws cov xwm tsis-lom, nws tuaj yeem luam tawm siv cov tshuab luam ntawv txuas ntxiv, uas tuaj yeem txhim kho kev ua tau zoo. Tam sim no, nws yog cov khoom siv uas nyiam tshaj plaws rau cov khoom siv hluav taws xob siab-zog rf.
3.Tej cov roj av (AL2O3) yog cov khoom siv uas nyiam tshaj plaws rau cov khoom siv hluav taws xob tsawg, raws li nws thermal conductivity yog li 1/5 ntawm aluminium nitride. Nws tsis tshua siv nyob rau hauv kev xaiv ntawm cov ntaub ntawv rau high-zog rf resistors.
Lub tshebTechnology Co., Ltd. yog cov kws tshaj lij kev tshaj lij ntawm passive Cheebtsam xws li RF detenors, RF foodenators, RF cais, RF CORTATORS, thiab lwm yam.
Nws cov khoom tau siv dav hauv cov kab ke xws li radar, microwave tshuab sib txuas lus, kev sib txuas lus sib txuas, xov tooj ntawm tes, thiab microwave sib xyaw ua ke.
Txij li thaum nws tsim tau, nyob rau hauv thiaj li tau txais cov neeg siv khoom zoo dua thiab muab tshuaj ntsuab tsim kho cov thev naus laus zis, cov khoom siv hluav taws xob uas muaj tam sim no nyob rau tib theem li cov qauv thoob ntiaj teb. Cov yam ntxwv zoo tshaj plaws ntawm cov khoom yog flatness, loj me me, thiab lub teeb hnyav.
Thiab nws muaj qhov zoo ntawm kev coj zoo thiab tus nqi qis, ua rau nws dav siv hauv microwave sib xyaw ua ke. Nrog kev loj hlob sai ntawm microwave tshuab xws li phased array radar, lawv daim ntawv thov kev cia siab yuav muaj kev cog lus ntau dua.
Lub tuam txhab yuav tu tsis tau nws tus kheej kom tau raws li cov neeg siv khoom, ua rau tsim cov yam ntxwv sib txawv thiab txhim kho cov khoom lag luam zoo, ntau yam, thiab kev pabcuam. Nqa cov neeg yuav khoom nrog peb lub siab, txav lawv nrog peb lub siab, thiab khwv tau lub koob npe nrov rau peb lub siab dawb paug.
Peb tau yeej txoj kev ntseeg siab ntawm peb cov neeg siv khoom siv siab thev naus laus zis, muaj txiaj ntsig zoo, ua tiav tau txiaj ntsig zoo rau lub teb chaws los tsim lub neej muaj kev sib raug zoo.
