I-Wilkinson isahluli samandlayisekethe esahluli samandla. Xa onke amazibuko edityanisiwe, anokuqonda ukwahlulwa phakathi kwamazibuko amabini aphumayo. Nangona isahluli samandla sikaWilkinson sinokuthi siyilwe ukufezekisa nakuphi na ukwahlulwa kwamandla (umzekelo, bona iPozar [1]), lo mzekelo uyakufunda imeko yokwahlulwa ngokulinganayo (3dB). I-FDTD iya kusetyenziselwa ukufumana iiparamitha zokusasazeka kwesixhobo.
I-Wilkinson isahluli samandlaIzicwangciso zeAnalog
Iqela lesakhiwo "umkhondo kunye nomthwalo" lisetyenziswe kwifayile ye-FDTD yokulinganisa i-Wilkinson_ power_ divider. Iiparamitha ezibonakalayo nezombane zeWilkinson isahluli samandla zakhiwe kwaye zisetwe kwi-fsp. I-microstrip transmission line imodeli isebenzisa i-two-dimensional perfect electrical conductor (PEC) ipleyiti yoxande ebekwe kwi-1.59mm engqindilili ye-substrate ene-dielectric constant constant ye-2.2. Ububanzi obufunekayo becandelo ngalinye lomgca wothumelo bubalwa kusetyenziswa i-equation. I-3.195 kunye ne-3.197 kwi-Pozar [1] (jonga ifayile yeskripthi ye-microstrip.lms kumzekelo we-microstrip) yi-4.9mm (Z0=50 ohms) kunye ne-2.804 mm (√ 2Z0=70.7 ohms) ngokulandelelana. Umgca wothumelo we-wavelength yekota wakhiwe kusetyenziswa iipoligoni ze-2D ezenziwe ngeringi. 3.194 kwi-Pozar [1] yi-λ g/4=55.5 mm. Isichasi similiselwa kusetyenziswa ipleyiti yoxande ye-2D echaza imathiriyeli ene-R=100 ohms.
Amazibuko abekwe kwi-input and output traces ukuba afake imowudi yokuhambisa umgca kwi-frequency range ye-0.5 - 1.5 GHz kwaye ubale iiparitha zokuchithwa kwezixhobo. Ukufumana iinkcukacha ezithe vetshe kwisetingi zayo, bona i-Ports page. Njengoko kuchaziwe ngezantsi, izibuko lomthombo liza kutshintshwa ngesandla ukuze litshise izibuko elinye ngexesha.
Indawo yokugubungela umnatha ibekwe kumzila ngamnye ukusombulula ubude nobubanzi bayo. Iipropati zokugoba kunye nee-angular zomkhondo wesebe zifuna ukuba ubungakanani begridi kwiindlela zika-x kunye no-y zilingane (dx=dy). Oku ayingomqobo kwisondlo kunye neengoma zemveliso ezilungelelaniswe kwi-coordinate axis. Ikopi yendawo yokugubungela umnatha esetyenziselwa ukulandelela isebe ibekwe ekunene kwemveliso yokulandelela ukugcina i-symmetrical mesh.
Umda wokufunxa we-PML ujikeleze yonke indawo yokulinganisa, ngaphandle komda we-z-minimum, ochongwe njengemeko yomda wesinyithi ukulinganisa indiza yokumisa umgca wothumelo lwe-microstrip.
I-Wilkinson isahluli samandla Iziphumo kunye nohlalutyo
Umzobo ongentla ubonisa ukuphendulwa rhoqo kweeparitha zokusabalalisa ezisetyenziselwa ukuhlukaniswa kunye nokulinganisa ukuhanjiswa kunye nokusabalalisa indawo yombane kwi-1GHz. La manani aveliswa ngumbhalo emva kokuba ukulinganisa kugqityiwe. Kufuneka kuqatshelwe ukuba ezi ziphumo zinokufumaneka kwi-trajectory usebenzisa i-meshes ecocekileyo kunezo zichazwe kwifayile yokulinganisa.
I-analogI-Wilkinson isahluli samandlaihambelana kakuhle kwigalelo layo (S11=- 40dB, f = 1.0GHz) kunye nemveliso (S22=- 32dB, f=1GHz) kumazibuko, inokwahlulwa okulungileyo (S32=- 43dB, f = 1GHz), kunye nokuphindaphinda kwayo kwiziko yi-1.01GHz, engaphakathi kwe-1% yoyilo olusebenza rhoqo lwe-1GHz. Ukongeza, siye saqaphela i-3dB elinganayo ulwahlulo lwamandla (S31 = - 3dB kwi-f = 1GHz) kunye notshintsho olungaphantsi kwe-10% kwibhendi ye-analog frequency.
Si Chuan Keenlion Microwave ukhetho olukhulu kwi-narrowband kunye noqwalaselo lwebroadband, egubungela amaza ukusuka kwi-0.5 ukuya kwi-50 GHz. Zenzelwe ukuphatha ukusuka kwi-10 ukuya kwi-30 igalelo lamandla kwi-50-ohm inkqubo yokuhambisa. Uyilo lweMicrostrip okanye lwestripline luyasetyenziswa, kwaye lulungiselelwe ukusebenza kakuhle.
Sinokwenza ngokwezifiso i-Power Divider ngokweemfuno zakho. Ungangenisa iiphepha lokulungiselela ukunika iinkcukacha ozifunayo.
