Isihlukanisi samandla saseWilkinsoniyisekethe yokuhlukanisa amandla. Uma wonke amachweba efaniswa, ingahlukanisa phakathi kwamachweba amabili okukhipha. Nakuba i-Wilkinson power divider ingaklanywa ukuze ihlukanise noma yikuphi ukuhlukaniswa kwamandla (isibonelo, bheka i-Pozar [1]), lesi sibonelo sizofunda icala lokuhlukanisa okulinganayo (3dB). I-FDTD izosetshenziselwa ukuthola amapharamitha okuhlakazeka kwedivayisi.
Isihlukanisi samandla saseWilkinsonIzilungiselelo ze-Analog
Iqembu lesakhiwo elithi "trace and load" lisetshenziswa kufayela lokulingisa le-FDTD i-Wilkinson_ power_ divider. Amapharamitha angokomzimba nakagesi e-Wilkinson power divider akhiwe futhi abekwe ku-fsp. Umugqa wokudlulisela we-microstrip uklanywe kusetshenziswa ipuleti elingunxande eliphelele elinobukhulu obubili (i-PEC) elibekwe ku-substrate enobukhulu obungu-1.59mm ene-dielectric constant ehlobene engu-2.2. Ububanzi obudingekayo besigaba ngasinye somugqa wokudlulisela bubalwa kusetshenziswa i-equation. 3.195 kanye no-3.197 ku-Pozar [1] (bheka ifayela lesikripthi se-microstrip.lms esibonelweni se-microstrip) angu-4.9mm (Z0=50 ohms) kanye no-2.804 mm (√ 2Z0=70.7 ohms) ngokulandelana. Umugqa wokudlulisela we-quarter wavelength wakhiwe kusetshenziswa ama-polygons e-2D akhiwe abe yindandatho. 3.194 ku-Pozar [1] ingu-λ g/4=55.5 mm. I-resistor yenziwe ngemodeli kusetshenziswa ipuleti elingunxande elingu-2D elichaza into ene-R=100 ohms.
Amachweba abekwe kuma-trace okufaka nokukhipha ukuze kufakwe imodi yomugqa wokudlulisa kububanzi bemvamisa obungu-0.5 - 1.5 GHz bese kubalwa amapharamitha okusabalala kwemishini. Ukuze uthole imininingwane eyengeziwe ngezilungiselelo zayo, bheka ikhasi lamachweba. Njengoba kuchaziwe ngezansi, ichweba lomthombo lizoshintshwa ngesandla ukuze lishaye ichweba elilodwa ngesikhathi.
Indawo yokumboza i-mesh ibekwa kuthrekhi ngayinye ukuze kuxazululwe ubude nobubanzi bayo. Izakhiwo zokugoba kanye ne-angular ze-branch trace zidinga ukuthi usayizi wegridi eziqondisweni zika-x no-y ulingane (dx=dy). Lokhu akulona isithiyo kumathrekhi okuphakelayo kanye nawokukhiphayo aqondaniswe ne-axis yokuxhumanisa. Ikhophi yendawo yokumboza i-mesh esetshenziselwa ukulandelela igatsha ibekwa ngakwesokudla kwe-output trace ukuze kugcinwe i-symmetrical mesh.
Isimo somngcele wokumuncwa kwe-PML sizungeze yonke indawo yokulingisa, ngaphandle komngcele we-z-minimum, obizwa ngokuthi isimo somngcele wensimbi esilingisa indiza yokumisa yomugqa wokudlulisela we-microstrip.
Isihlukanisi samandla saseWilkinson Imiphumela nokuhlaziywa
Isithombe esingenhla sibonisa impendulo yemvamisa yamapharamitha okuhlakaza asetshenziselwa ukulingisa ukuhlukaniswa nokudlulisa kanye nokusatshalaliswa kwensimu kagesi ku-1GHz. Lezi zinombolo zikhiqizwa yiskripthi ngemuva kokuba ukulingisa sekuqediwe. Kufanele kuqashelwe ukuthi le miphumela ingatholakala endleleni yokusebenzisa ama-meshes amancane kunalawo achazwe kufayela lokulingisa.
I-analogIsihlukanisi samandla saseWilkinsonihambisana kahle nezimbobo zayo zokufaka (S11=- 40dB, f=1.0GHz) kanye nokukhipha (S22=- 32dB, f=1GHz), ine-isolation enhle (S32=- 43dB, f=1GHz), kanti imvamisa yayo ephakathi ingu-1.01GHz, okungaphakathi kwe-1% yemvamisa yokusebenza yomklamo engu-1GHz. Ngaphezu kwalokho, sibone ukwahlukaniswa kwamandla okulingana kwe-3dB (S31=- 3dB ku-f=1GHz) ngokushintsha okungaphansi kuka-10% ebhendini yemvamisa ye-analog.
I-Si Chuan Keenlion Microwave iyindlela enkulu yokukhetha ama-narrowband kanye nama-broadband, ahlanganisa amaza omsindo asukela ku-0.5 kuya ku-50 GHz. Aklanyelwe ukuphatha amandla okufaka angu-10 kuya ku-30 watts ohlelweni lokudlulisa olungu-50 ohm. Kusetshenziswa imiklamo ye-Microstrip noma ye-stripline, futhi ilungiselelwe ukusebenza kahle kakhulu.
Singakwazi futhi ukwenza ngokwezifiso i-Power Divider ngokwezidingo zakho. Ungangena ku-ikhasi lokwenza ngokwezifiso ukuze unikeze imininingwane oyidingayo.
