QHAGAMSHELANA NGOKU

Izikhokelo zamaza ze-RF zizixhobo ezithumela amandla ukusuka kwenye indawo ukuya kwenye. Endaweni yokudlulisa amandla ngqo kwindawo yonke njenge-antenna, isikhokelo samaza e-microwave sinokuwagcina amandla kwisinyithi esingenanto, nto leyo enciphisa kakhulu ukulahleka ngexesha lokudluliselwa kwamandla. Isikhokelo samaza e-millimeter sinokuqondwa njenge-antenna enamandla ngokukodwa, kwaye amandla anokusasazwa kuphela kwisikhokelo samaza, kwaye awanakusasazeka kwenye indawo.
I-Waveguide transition yenye ye-waveguide, esetyenziswa kakhulu kwiindawo ezahlukeneyo, kuquka kodwa kungaphelelanga apho kunxibelelwano lwe-microwave, iinkqubo ze-radar, ii-satellites zonxibelelwano kunye nezixhobo ze-microwave radio link. Kukho iintlobo ezininzi ze-waveguide transitions, zihlala zisebenza kakuhle, i-standing wave eqhelekileyo i-VSWR≤1.2 ngaphakathi kwe-bandwidth epheleleyo ye-waveguide, izixhobo ezisisiseko kubandakanya ubhedu, i-aluminium, iindlela zonyango lomphezulu i-silver plating, i-gold plating, i-nickel plating, i-passivation, i-conductive oxidation, njl.

Iimbonakalo:

Uphawu oluqhelekileyo lwe-transition waveguide kukuba ezi ports zimbini zisebenzisa iintlobo ezahlukeneyo ze-waveguide ukuguqula phakathi kweentlobo ezahlukeneyo ze-waveguide. Umzekelo:
1. Ii-waveguide ukuya kwi-microstrip converters: Ii-waveguide ukuya kwi-microstrip converters zisetyenziswa kakhulu ekufumaneni ii-millimeter wave monolithic integrated circuits kunye nee-hybrid circuits, kunye nokudibanisa ii-waveguide ukuya kwii-planar circuits ukuqinisekisa ukuba utshintsho luhambelana kakuhle phakathi kwemigca emibini yothumelo.
2. Utshintsho ukusuka kwi-waveguides eziphindwe kabini ukuya kwi-waveguides ezingxande: I-waveguides ezitshintshiweyo ezichanekileyo ngomatshini zinokuqhagamshela i-waveguides ezingxande kabini kwi-waveguides ezingxande, zibonelela ngokulahlekelwa okuncinci kokufakwa kunye nokuhambelana okuphezulu. Olu hlobo lwe-waveguides zotshintsho lufanelekile ukufakwa kwilabhoratri kunye nokulinganisa indibano kunye nezixhobo ze-waveguides ezingxande ezimbini
3. Utshintsho lwe-waveguide engunxande: I-waveguide engunxande iguqula ngokufanayo imo ye-TE10 kwimo ye-waveguide engunxande eqhelekileyo ukuya kwimo ye-TE11 kwi-waveguide ejikelezayo. Olu tshintsho lubalulekile ekudluliseni ngokufanelekileyo imiqondiso ukusuka kwi-waveguide engunxande eqhelekileyo ukuya kwi-waveguide ejikelezayo, ngakumbi kwizicelo apho olu tshintsho lwemo ethile lufunekayo.

I-QualwaveIinkonzo zotshintsho lwe-waveguide zigubungela uluhlu lwamaza ukuya kuthi ga kwi-220GHz, kunye notshintsho lwe-waveguide olulungiselelwe wena ngokweemfuno zabathengi.
