Cov kev txwv ntawm cov khoom faib hluav taws xob hauv cov ntawv thov sib txuas ua ke muaj zog tuaj yeem yog vim cov yam tseem ceeb hauv qab no:
1. Kev Txwv Kev Tswj Fais Fab ntawm Tus Resistor Rho Tawm (R)
- Hom faib fais fab:
- Thaum siv ua lub zog faib hluav taws xob, lub teeb liab nkag ntawmINraug faib ua ob lub co-frequency, co-phase signals ntawm cov ntsiab lusAthiabB.
- Lub resistor isolationRtsis muaj qhov sib txawv ntawm qhov hluav taws xob, ua rau tsis muaj qhov ntws tam sim no thiab tsis muaj kev ploj hluav taws xob. Lub peev xwm hluav taws xob tsuas yog txiav txim siab los ntawm lub peev xwm tswj hluav taws xob ntawm cov kab microstrip.
- Hom Sib Xyaws:
- Thaum siv ua ib qho combiner, ob lub teeb liab ywj pheej (los ntawm OUT1thiabOUT2) nrog cov zaus sib txawv lossis theem sib txawv raug siv.
- Muaj qhov sib txawv ntawm voltage ntawmAthiabB, ua rau muaj kev ntws tam sim no los ntawm RLub zog tau ploj mus rau hauvRsib npaug½ (TAWM 1 + TAWM 2)Piv txwv li, yog tias txhua qhov nkag yog 10W,Ryuav tsum tiv taus ≥10W.
- Txawm li cas los xij, qhov resistor cais tawm hauv cov khoom faib hluav taws xob txheem feem ntau yog cov khoom siv hluav taws xob tsawg nrog kev tso cua sov tsis txaus, ua rau nws yooj yim ua rau tsis ua haujlwm thermal nyob rau hauv cov xwm txheej muaj zog siab.
2. Cov Kev Txwv ntawm Kev Tsim Qauv
- Cov Kev Txwv ntawm Microstrip Line:
- Cov khoom faib fais fab feem ntau siv los ntawm kev siv cov kab microstrip, uas muaj peev xwm tswj hwm fais fab tsawg thiab tsis txaus tswj hwm thermal (piv txwv li, me me, thaj chaw tso cua sov tsawg).
- Lub resistorRTsis yog tsim los rau kev siv hluav taws xob ntau, ua rau kev ntseeg siab ntxiv rau hauv kev siv combiner.
- Kev rhiab heev ntawm theem / zaus:
- Txhua theem lossis zaus tsis sib xws ntawm ob lub teeb liab nkag (feem ntau hauv cov xwm txheej tiag tiag) ua rau lub zog ploj mus ntau duaRua rau lub zog thermal nce ntxiv.
3. Cov Kev Txwv hauv Cov Xwm Txheej Zoo Tshaj Plaws Co-Frequency / Co-Phase
- Cov Ntaub Ntawv Theoretical:
- Yog tias ob lub tswv yim zoo sib xws co-frequency thiab co-phase (piv txwv li, synchronized amplifiers tsav los ntawm tib lub teeb liab),Rtsis muaj zog, thiab tag nrho lub zog sib xyaw ua ke ntawmIN.
- Piv txwv li, ob lub tswv yim 50W tuaj yeem sib xyaw ua ke rau hauv 100W ntawm INyog tias cov kab microstrip tuaj yeem tswj tau tag nrho lub zog.
- Cov Kev Sib Tw Ua Tau Zoo:
- Kev sib dhos zoo meej yuav luag tsis yooj yim sua kom tswj tau hauv cov kab ke tiag tiag.
- Cov khoom faib fais fab tsis muaj zog rau kev sib koom ua ke muaj zog, vim tias txawm tias qhov tsis sib xws me me tuaj yeem ua rauRkom nqus tau cov hluav taws xob tsis tau xav txog, ua rau tsis ua haujlwm.
4. Qhov Zoo Tshaj Plaws ntawm Lwm Txoj Kev Daws Teeb Meem (piv txwv li, 3dB Hybrid Couplers)
- 3dB Hybrid Couplers:
- Siv cov qauv qhov nrog cov qhov kawg ntawm sab nraud uas muaj zog siab, ua rau muaj kev tso cua sov zoo thiab muaj peev xwm tswj tau hluav taws xob siab (piv txwv li, 100W+).
- Muab kev cais tawm ntawm cov chaw nres nkoj thiab zam rau qhov tsis sib xws ntawm theem / zaus. Lub zog tsis sib xws raug xa mus rau qhov thauj khoom sab nraud kom muaj kev nyab xeeb es tsis txhob ua rau cov khoom sab hauv puas tsuaj.
- Kev Tsim Qauv Yooj Yim:
- Cov qauv tsim raws li qhov cavity tso cai rau kev tswj hwm thermal scalable thiab kev ua tau zoo hauv cov ntawv thov muaj zog, tsis zoo li microstrip-based power dividers.

Cov khoom faib fais fab tsis haum rau kev sib xyaw ua ke muaj zog siab vim yog lub peev xwm tswj hwm hluav taws xob ntawm lub resistor cais tawm, tsis tsim kom muaj cua sov txaus, thiab muaj kev nkag siab rau qhov tsis sib xws ntawm theem / zaus. Txawm tias nyob rau hauv cov xwm txheej zoo tagnrho, cov qauv thiab kev ntseeg tau ua rau lawv tsis yooj yim. Rau kev sib xyaw ua ke ntawm cov teeb liab muaj zog siab, cov khoom siv tshwj xeeb xws li 3dB hybrid couplersLawv nyiam dua, muab kev ua haujlwm thermal zoo dua, kev kam rau qhov tsis sib xws, thiab kev sib raug zoo nrog cov qauv tsim hluav taws xob siab.
Lub Tswv Yim muab tag nrho cov khoom siv microwave passive rau tub rog, Aerospace, Electronic Countermeasures, Satellite Communication, Trunking Communication applications: Power divider, directional coupler, filter, duplexer, nrog rau LOW PIM Cheebtsam txog li 50GHz, nrog rau qhov zoo thiab tus nqi sib tw.
