I-Waveguide Transitions RF Microwave Millimeter Wave Radio
Amagagasi e-RF angamadivayisi adlulisa amandla esuka endaweni eyodwa aye kwenye. Esikhundleni sokukhipha amandla ngqo kuso sonke isikhala njengothi, i-microwave waveguide ingavalela amandla ensimbi engenalutho, okunciphisa kakhulu ukulahleka ngesikhathi sokudluliselwa kwamandla. I-waveguide eyimilimitha ingaqondwa njenge-antenna eqondisayo eqinile, futhi amandla angasakazwa kuphela ku-waveguide, futhi awakwazi ukusakazeka kwenye indawo.
I-Waveguide Transition ingenye ye-waveguide, esetshenziswa kabanzi emikhakheni eyahlukene, ehlanganisa kodwa engagcini nje kwezokuxhumana nge-microwave, izinhlelo ze-radar, amasathelayithi okuxhumana kanye nemishini yokuxhumanisa umsakazo we-microwave. Kunezinhlobo eziningi zezinguquko ze-waveguide, ngokuvamile ezinokusebenza okuphezulu, igagasi lokuma elivamile le-VSWR≤1.2 ngaphakathi komkhawulokudonsa ogcwele we-waveguide, izinto eziyisisekelo ezihlanganisa ithusi, i-aluminium, izindlela zokwelapha ezingaphezulu i-silver plating, i-golide plating, i-nickel plating, i-passivation, i-conductive oxidation, njll.

Isici esijwayelekile senguquko ye-waveguide ukuthi amachweba amabili asebenzisa izinhlobo ezahlukene ze-waveguide ukuze aguqule phakathi kwezinhlobo ezihlukene ze-waveguide. Ngokwesibonelo:
1. I-Waveguide to microstrip converters: I-Waveguide to microstrip converters isetshenziswa kabanzi ekutholeni ama-millimeter wave monolithic amasekhethi ahlanganisiwe namasekhethi ayingxubevange, kanye nasekuxhunyweni kwe-waveguide kumasekhethi apulani ukuze kuqinisekiswe ukushintshwa okufaniswa kahle phakathi kwemigqa emibili yokudlulisela.
2. Ushintsho olusuka kumagagasi anamagagasi anamagquma amabili ukuya kumagagasi angunxande: Amagagasi okushintshana asebenza ngomshini anembile angaxhuma amagagasi anamagagasi aphindwe kabili kumagagasi angunxande, anikeze ukulahlekelwa kokufaka okuphansi nokuhambisana okuphezulu. Lolu hlobo lwe-waveguide yoguquko lufanele ukufakwa kwelabhorethri kanye nokukalwa kwe-waveguide waveguide ehlanganiswe kabili nemishini
3. Inguquko ye-waveguide engunxande: I-waveguide engunxande iguqula ngokufanayo imodi ye-TE10 ku-waveguide engunxande evamile ibe imodi ye-TE11 ku-waveguide eyindilinga. Lokhu kuguqulwa kubalulekile ukuze kudluliselwe amasiginali ngempumelelo ukusuka ku-waveguide engunxande evamile ukuya ku-waveguide eyindilinga, ikakhulukazi ezinhlelweni zokusebenza lapho ukuguqulwa kwemodi ethile kuyadingeka.
QualwaveIhlinzeka ngoshintsho lwe-waveguide imboza ibanga lemvamisa elifika ku-220GHz, kanye noguquko olwenziwe ngokwezifiso lwe-waveguide ngokuya ngezidingo zamakhasimende.
