RF resistor yog dab tsi?
RF resistor yog dab tsi? Hais yooj yim xwb, cov resistors siv hauv RF microwave kev sib txuas lus hu ua RF resistors.
Txhua tus neeg yuav tsum paub txog xov tooj cua zaus tam sim no, uas yog ib lo lus luv rau cov nthwv dej electromagnetic waves uas muaj zaus hloov pauv ntau zaus.
Ib qho hluav taws xob zaus siab uas hloov pauv ntau dua 10000 zaug hauv ib ob hu ua hluav taws xob zaus xov tooj cua.
RF resistor yog ib lub cuab yeej passive uas tuaj yeem thaiv kev hla ntawm lub xov tooj cua zaus tam sim no. Thiab hloov lub zog hluav taws xob mus rau hauv cua sov lossis lwm hom zog, nrog rau chav tsev ntawm ohms (Ω) zoo ib yam li kev tiv thaiv ib txwm muaj.
RF resistors feem ntau yog cais raws li lub zog, thiab muaj ntau txoj hauv kev los cais lawv:
Faib raws li cov qauv sab nraud, nws tuaj yeem faib ua:
1. Chip Resistor (chip resistors yog muab faib ua ib qho electrode chip resistor thiab dual electrode chip resistors)
2. Cov Resistor uas ua los ntawm cov hlau lead (cov resistor uas ua los ntawm cov hlau lead yog muab faib ua cov resistor uas ua los ntawm cov hlau lead thiab cov resistor uas ua los ntawm cov hlau lead ob npaug)
3. Flanged Resistor (flanged resistors raug muab faib ua ib qho txhuas flanged resistors thiab dual flanged resistors)
Raws li kev faib tawm cov txheej txheem ntau lawm, nws tuaj yeem muab faib ua:
1. Cov yeeb yaj kiab tuab RF resistor (hu ua cov yeeb yaj kiab tuab resistor)
2. Cov yeeb yaj kiab nyias nyias RF resistor (hu ua cov yeeb yaj kiab nyias nyias resistor)
Raws li kev faib tawm lub zog, nws tuaj yeem faib ua:
1. Lub zog siab RF resistor (hu ua lub zog siab resistor, feem ntau xa mus rau cov resistors nrog lub zog ntawm 60W lossis ntau dua)
2. Lub zog qis RF resistor (luv luv li lub zog qis resistor, feem ntau xa mus rau lub zog resistors hauv qab 20W)
Faib raws li zaus, nws tuaj yeem faib ua:
1. Lub zog RF siab (hu ua lub zog siab, feem ntau yog lub zog nrog zaus siab dua 3GHz)
2. Tsawg zaus RF resistor (luv luv li tsawg zaus resistor, feem ntau yog ib qho resistor nrog zaus qis dua 3GHz)
Cov ntaub ntawv thiab qhov zoo thiab qhov tsis zoo rau kev ua RF resistors:
1. Beryllium oxide (BeO) muaj cov thermal conductivity siab, yuav luag sib npaug rau tooj liab ntshiab thiab txhuas, nrog rau cov coefficient thermal conductivity ntawm 200-250W (mK), ua rau nws yog cov khoom siv nyiam rau kev ua RF resistors. Nws qhov tsis zoo tshaj plaws yog tias nws muaj tshuaj lom heev hauv cov hmoov, ua rau nws nyuaj rau cov qhov txhab sib cuag kom kho. Yog li feem ntau, cov chaw tsim khoom ntawm RF resistors yuav cov ntaub ntawv molded thiab tsis xav tau kev ua tiav theem ob. Qhov no ua rau siv beryllium oxide (BeO) los ua RF resistors uas tsuas yog tuaj yeem luam tawm ntawm ib lub nti, txo qis kev ua haujlwm ntau lawm.
2. Aluminium nitride (AlN) kuj yog ib yam khoom uas muaj thermal conductivity siab, nrog rau thermal conductivity ntawm li 20W / mK Nws muaj cov khoom siv zoo thiab muaj zog flexural ntau dua li aluminium oxide thiab beryllium oxide ceramics. Vim nws tsis muaj tshuaj lom, nws tuaj yeem luam tawm siv cov thev naus laus zis luam ntawv tas mus li, uas tuaj yeem txhim kho kev tsim khoom ntau lawm. Tam sim no, nws yog cov khoom siv nyiam rau cov resistors RF muaj zog siab.
3. Aluminium oxide (Al2O3) yog cov khoom siv zoo tshaj plaws rau cov resistors uas muaj zog tsawg, vim nws cov thermal conductivity yog li 1/5 ntawm txhuas nitride. Nws tsis tshua siv rau hauv kev xaiv cov ntaub ntawv rau cov resistors RF muaj zog siab.
RFTYTTechnology Co., Ltd. yog ib lub chaw tsim khoom ntawm cov khoom siv passive xws li RF resistors, RF attenuators, coaxial loads, coaxial attenuators, adjustable attenuators, RF isolators, RF circulators, thiab lwm yam.
Nws cov khoom siv dav dav hauv cov kab ke xws li radar, cov twj paj nruag, kev taw qhia, microwave multi-channel kev sib txuas lus, qhov chaw thev naus laus zis, kev sib txuas lus txawb, kev xa duab, thiab microwave integrated circuits.
Txij li thaum nws tau tsim los, txhawm rau kom pab tau cov neeg siv khoom zoo dua thiab muab rov qab rau lub zej zog, lub tuam txhab tau tsom mus rau thev naus laus zis thiab tsim cov microstrip isolators / circulators uas tam sim no nyob rau tib theem li cov qauv thoob ntiaj teb. Cov yam ntxwv zoo tshaj plaws ntawm cov khoom yog qhov tiaj tus, me me, thiab hnyav sib.
Thiab nws muaj qhov zoo ntawm kev sib xws zoo thiab tus nqi qis, ua rau nws siv dav hauv microwave integrated circuits. Nrog rau kev txhim kho sai ntawm cov kab ke microwave xws li phased array radar, lawv cov kev thov yuav muaj kev cia siab ntau dua.
Lub tuam txhab yuav mob siab rau nws tus kheej kom ua tau raws li qhov xav tau ntawm cov neeg siv khoom, siv zog los tsim kom muaj cov yam ntxwv tshwj xeeb thiab txhim kho cov khoom zoo, ntau yam, thiab kev pabcuam tas li. Txhawb nqa cov neeg siv khoom nrog peb lub siab, txav lawv nrog peb txoj kev xav, thiab khwv tau lub koob npe nrov rau peb txoj kev ua siab dawb siab zoo.
Peb tau txais kev ntseeg siab ntawm peb cov neeg siv khoom nrog kev siv thev naus laus zis siab, zoo, thiab kev pabcuam siab, ua tiav kev sib pab thiab muab kev nyob ruaj khov rau lub tebchaws los tsim kom muaj kev sib haum xeeb.
