QHAGAMSHELANA NGOKU

Ii-Waveguides zizixhobo ezihambisa amandla ukusuka kwenye indawo ukuya kwenye. Esikhundleni sokukhupha amandla ngokuthe ngqo kwindawo yonke njenge-eriyali, i-waveguide inokuvala amandla kwisinyithi esingenanto, esinciphisa kakhulu ilahleko ngexesha lokuhanjiswa kwamandla. I-waveguide inokuqondwa njenge-eriyali eyomeleleyo, kwaye amandla anokusasazwa kuphela kwi-waveguide, kwaye ayinakusasazwa kwenye indawo.
Ukutshintshwa kwe-Waveguide yenye ye-waveguide, esetyenziswa ngokubanzi kwiinkalo ezahlukeneyo, kubandakanywa kodwa kungaphelelanga kunxibelelwano lwe-microwave, iinkqubo ze-radar, iisathelayithi zonxibelelwano kunye nezixhobo ze-radio link microwave. Kukho iintlobo ezininzi zenguqu ye-waveguide, ehlala isebenza ngokuphezulu, i-VSWR≤1.2 ye-wave wave egcweleyo, izixhobo ezisisiseko ezibandakanya ubhedu, i-aluminiyam, iindlela zonyango lomphezulu wesilivere, ukucwenga kwegolide, ukufakwa kwe-nickel, i-passivation, i-oxidation eqhubayo, njl. .

Iimbonakalo:

Uphawu oluqhelekileyo lwenguquko ye-waveguide kukuba la mazibuko mabini asebenzisa iindidi ezahlukeneyo ze-waveguide uguqulo phakathi kweentlobo ezahlukeneyo zamaza. Umzekelo:
1. I-Waveguide ukuya kubaguquli be-microstrip: I-Waveguide kwi-converter ye-microstrip isetyenziswa ngokubanzi ekubhaqweni kweesekethe ezidibeneyo ze-millimeter wave monolithic kunye neesekethe ezixubileyo, kunye nokudityaniswa kwe-waveguide kwiisekethe ezicwangcisiweyo zokuqinisekisa uguquko oluhambelana kakuhle phakathi kwemigca emibini yokuhambisa. .
2. Ukutshintsha ukusuka kumaza amaza anamaza aphindwe kabini ukuya kumaza oxande: Ukuchaneka okwenziwe ngomatshini amaza okutshintsha amaza angadibanisa amaza amaza aphindwe kabini ukuya kumaza oxande, ukunika ilahleko yokufaka ephantsi kunye nokuhambelana okuphezulu. Olu hlobo lotshintsho lwe-waveguide lulungele ukufakelwa kwelabhoratri kunye nomlinganiselo wendibano yamaza oxande ephindwe kabini kunye nezixhobo.
3. Utshintsho lwamaza oxande: I-waveguide yoxande iguqula ngokufanayo imo ye-TE10 kwi-standard ye-rectangular waveguide ukuya kwimo ye-TE11 kwi-waveguide ejikelezayo. Olu guqulelo lubalulekile ekugqithiseni imiqondiso ngokufanelekileyo ukusuka kwinqanaba eliqhelekileyo le-rectangular waveguide ukuya kwisetyhula, ngakumbi kwizicelo apho olu tshintsho lwendlela ethile lufuneka khona.

QualwaveIbonelela ngeenguqu ze-waveguide zigubungela uluhlu lwamaza ukuya kuthi ga kwi-173GHz, kunye noguquko olulungiselelweyo lwe-waveguide ngokweemfuno zabathengi.
