Wilkinson zog divideryog lub zog faib hluav taws xob Circuit Court. Thaum tag nrho cov chaw nres nkoj sib tw, nws tuaj yeem paub kev sib cais ntawm ob qhov chaw tso zis. Txawm hais tias Wilkinson lub zog faib hluav taws xob tuaj yeem tsim los kom paub txog kev faib hluav taws xob (piv txwv li, saib Pozar [1]), qhov piv txwv no yuav kawm txog qhov sib npaug (3dB). FDTD yuav raug siv kom tau txais cov kev faib tawm ntawm cov cuab yeej.

Cov qauv pawg "txoj kab thiab thauj khoom" yog siv hauv FDTD simulation file Wilkinson_ power_ divider. Lub cev thiab hluav taws xob tsis zoo ntawm Wilkinson lub zog faib hluav taws xob tau tsim thiab teeb tsa hauv fsp. Lub microstrip kis kab yog ua qauv siv ob lub qhov muag zoo tshaj plaws hluav taws xob hluav taws xob (PEC) daim duab plaub tso rau ntawm 1.59mm tuab substrate nrog cov txheeb ze dielectric tas li ntawm 2.2. Qhov dav yuav tsum tau muaj ntawm txhua seem kis tau tus mob yog xam los ntawm kev sib npaug. 3.195 thiab 3.197 hauv Pozar [1] (saib microstrip.lms script file hauv microstrip piv txwv) yog 4.9mm (Z0 = 50 ohms) thiab 2.804 mm (√ 2Z0 = 70.7 ohms) feem. Lub quarter wavelength kis tau tus mob yog tsim los siv 2D polygons tsim rau hauv ib lub nplhaib. 3.194 nyob rau hauv Pozar [1] yog λ g / 4 = 55.5 mm. Lub resistor yog qauv siv 2D daim duab plaub uas qhia txog cov khoom siv nrog R = 100 ohms.
Cov chaw nres nkoj tau muab tso rau ntawm cov tswv yim thiab cov khoom tso tawm kom txhaj cov kab kis tau tus mob hauv qhov ntau zaus ntawm 0.5 - 1.5 GHz thiab suav cov kev faib tawm ntawm cov khoom siv. Yog xav paub ntxiv txog nws qhov chaw, saib nplooj ntawv Ports. Raws li tau piav qhia hauv qab no, qhov chaw nres nkoj yuav raug hloov manually los tua ib qho chaw nres nkoj ib zaug.
Cov cheeb tsam mesh tau muab tso rau ntawm txhua txoj kev los daws nws qhov ntev thiab qhov dav. Qhov dabtsi yog khoov thiab angular zog ntawm ceg kab yuav tsum tau hais tias daim phiaj loj nyob rau hauv cov lus qhia x thiab y yog sib npaug (dx = dy). Qhov no tsis yog ib qho kev txwv ntawm cov khoom noj thiab cov khoom tso tawm raws li qhov sib koom ua ke. Ib daim ntawv theej ntawm thaj chaw mesh siv rau cov ceg taug qab yog muab tso rau sab xis ntawm cov khoom tso tawm kom muaj qhov sib luag mesh.
PML kev nqus ciam ciam nyob ib puag ncig tag nrho cov simulation cheeb tsam, tshwj tsis yog rau z-tsawg kawg ntawm ciam teb, uas raug xaiv raws li cov hlau ciam teb simulating lub dav hlau grounding ntawm microstrip kis kab.
Wilkinson zog divider Cov txiaj ntsig thiab kev tsom xam
Daim duab saum toj no qhia tau hais tias cov lus teb zaus ntawm kev sib faib tsis siv rau kev sib cais thiab kev sib kis simulation thiab cov hluav taws xob xa hluav taws xob ntawm 1GHz. Cov lej no yog tsim los ntawm tsab ntawv tom qab simulation tiav. Nws yuav tsum raug sau tseg tias cov txiaj ntsig no tuaj yeem tau txais ntawm txoj hauv kev siv cov meshes zoo dua li cov teev hauv cov ntaub ntawv simulation.
Qhov analogWilkinson zog dividerNws zoo sib xws ntawm nws cov tswv yim (S11 = - 40dB, f = 1.0GHz) thiab tso zis (S22 = - 32dB, f = 1GHz) cov chaw nres nkoj, muaj kev sib cais zoo (S32 = - 43dB, f = 1GHz), thiab nws qhov nruab nrab zaus yog 1.01GHz, uas yog nyob rau hauv 1% ntawm kev khiav hauj lwm frequency 1 GHz. Tsis tas li ntawd, peb tau pom 3dB sib npaug zog faib (S31 = - 3dB ntawm f = 1GHz) nrog kev hloov pauv tsawg dua 10% hauv qhov sib txawv zaus band.
Si Chuan Keenlion Microwave ib qho kev xaiv loj hauv qhov nqaim thiab kev teeb tsa dav dav, suav nrog zaus ntawm 0.5 txog 50 GHz. Lawv tau tsim los tswj los ntawm 10 mus rau 30 watts input zog hauv 50-ohm kis tau tus mob. Microstrip los yog stripline designs yog siv, thiab optimized rau kev ua tau zoo tshaj plaws.
Peb kuj tuaj yeem kho lub Fais Fab Divider raws li koj xav tau. Koj tuaj yeem nkag mus raucustomization nplooj los muab cov specifications koj xav tau.
