Cov kev txwv ntawm cov hluav taws xob faib hluav taws xob nyob rau hauv high-power combining applications tuaj yeem raug ntaus nqi rau cov hauv qab no:
cov1. Fais fab kev txwv ntawm kev rho tawm Resistor (R)cov
- covFais fab Divider hom:
- Thaum siv los ua lub zog faib hluav taws xob, lub teeb liab input ntawmINyog muab faib ua ob co-frequency, co-phase signals ntawm cov ntsiab lusAthiabB.
- Kev rho tawm resistorRKev paub tsis muaj qhov sib txawv voltage, ua rau xoom tam sim no ntws thiab tsis muaj hluav taws xob dissipation. Lub zog muaj peev xwm tsuas yog txiav txim siab los ntawm microstrip kab lub peev xwm tuav lub zog.
- covCombiner hom:
- Thaum siv los ua ib qho kev sib txuas, ob qho kev ywj pheej (los ntawmOUT 1thiabOUT 2) nrog ntau zaus los yog theem yog siv.
- Qhov sib txawv voltage tshwm sim ntawmAthiabB, ua rau tam sim no ntws los ntawmR. Lub zog dissiped nyob rau hauvRsib npaug½ (OUT1 + OUT2). Piv txwv li, yog tias txhua lub tswv yim yog 10W,Ryuav tsum tiv taus ≥10W.
- Txawm li cas los xij, qhov kev sib cais ntawm cov hluav taws xob sib cais hauv cov qauv hluav taws xob feem ntau yog cov khoom siv hluav taws xob tsawg nrog cov cua sov tsis txaus, ua rau nws ua rau thermal tsis ua hauj lwm nyob rau hauv high-power tej yam kev mob.
cov2. Cov qauv tsim kev txwvcov
- covMicrostrip Kab txwv:
- Fais fab faib feem ntau yog siv los siv cov kab microstrip, uas muaj peev xwm tuav lub hwj chim thiab tsis muaj kev tswj xyuas thermal (xws li, lub cev me me, qhov chaw tsis muaj cua sov).
- Qhov resistorRTsis yog tsim los rau cov hluav taws xob siab dissipation, ntxiv kev txwv kev cia siab rau hauv cov ntawv thov sib xyaw.
- covPhase/Frequency Sensitivity:
- Txhua theem lossis zaus tsis sib haum xeeb ntawm ob lub tswv yim tawm tswv yim (ib txwm nyob rau hauv lub ntiaj teb tiag tiag scenarios) tsub kom lub zog dissipation hauvR, exacerbating thermal kev nyuaj siab.
cov3. Cov kev txwv hauv qhov zoo tshaj plaws Co-Frequency/Co-Phase Scenarioscov
- covTheoretical Case:
- Yog hais tias ob lub inputs zoo kawg nkaus co-frequency thiab co-theem (xws li, synchronized amplifiers uas tau tsav los ntawm tib lub teeb liab),Rdissipates tsis muaj zog, thiab tag nrho lub zog yog ua ke ntawmIN.
- Piv txwv li, ob lub 50W inputs tuaj yeem ua ke rau hauv 100W ntawmINyog tias cov kab microstrip tuaj yeem tswj tau tag nrho lub zog.
- covKev Sib Tw:
- Perfect theem alignment yog yuav luag tsis yooj yim sua kom tswj tau nyob rau hauv tiag tiag systems.
- Fais fab faib tsis muaj robustness rau high-power combining, raws li txawm me me mismatches yuav ua rauRkom nqus tau lub zog tsis txaus ntseeg, ua rau tsis ua haujlwm.
cov4. Superiority ntawm Alternative Solutions (xws li, 3dB Hybrid Couplers)cov
- cov3dB Hybrid Couplers:
- Siv cov kab noj hniav nrog cov khoom siv hluav taws xob sab nraud, ua kom muaj cua sov kom zoo thiab muaj peev xwm tuav tau siab (piv txwv li, 100W +).
- Muab qhov kev sib cais ntawm cov chaw nres nkoj thiab zam cov theem / zaus tsis sib haum. Lub zog tsis sib haum xeeb yog kev nyab xeeb rau kev thauj khoom sab nraud es tsis ua rau cov khoom siv sab hauv puas.
- covTsim Flexibility:
- Cavity-based designs tso cai rau scalable thermal tswj thiab kev ua tau zoo nyob rau hauv high-power applications, tsis zoo li microstrip-raws li lub hwj chim faib.
covXauscov
Fais fab faib yog tsis tsim nyog rau high-power combining vim hais tias ntawm cov kev sib cais resistor lub peev xwm tuav lub hwj chim, tsis txaus thermal tsim, thiab rhiab heev rau theem / zaus tsis sib haum. Txawm tias nyob rau hauv qhov zoo tshaj plaws co-theem scenarios, structural thiab kev cia siab rau constraints ua rau lawv impractical. Rau high-power teeb liab combining, mob siab rau li3dB hybrid txuasyog nyiam, muab superior thermal kev ua tau zoo, kam rau siab rau mismatches, thiab compatibility nrog kab noj hniav raws li high-power designs.
Lub tswv yim muaj ntau yam ntawm passive microwave Cheebtsam rau tub rog, Aerospace, Electronic Countermeasures, Satellite Communication, Trunking Communication applications: Fais fab faib, directional coupler, lim, duplexer, raws li zoo raws li LOW PIM Cheebtsam mus txog 50GHz, nrog zoo zoo thiab sib tw nqi.
