XHUMANA MANJE

Ama-RF waveguides amadivayisi adlulisa amandla kusuka endaweni eyodwa kuya kwenye. Esikhundleni sokukhipha amandla ngqo endaweni yonke njenge-antenna, i-microwave waveguider ingagcina amandla ensimbi engenalutho, okunciphisa kakhulu ukulahleka ngesikhathi sokudluliselwa kwamandla. I-millimeter wave wave guider ingaqondwa njenge-antenna eqinile kakhulu eqondisa ngqo, futhi amandla angasakazwa kuphela ku-waveguider, futhi awakwazi ukusabalala kwenye indawo.
Ukuguqulwa kwe-Waveguide kungenye ye-waveguide, esetshenziswa kabanzi emikhakheni eyahlukahlukene, kufaka phakathi kodwa kungagcini ngokuxhumana kwe-microwave, izinhlelo ze-radar, amasathelayithi okuxhumana kanye nemishini yokuxhumanisa umsakazo we-microwave. Kunezinhlobo eziningi zokuguqulwa kwe-waveguide, ngokuvamile okune-high performance, i-standing wave ejwayelekile i-VSWR≤1.2 ngaphakathi kwe-bandwidth ephelele ye-waveguide, izinto eziyisisekelo ezifaka ithusi, i-aluminium, izindlela zokwelapha ubuso i-silver plating, i-gold plating, i-nickel plating, i-passivation, i-conductive oxidation, njll.

Izici:

Isici esijwayelekile se-transition waveguide ukuthi amachweba amabili asebenzisa izinhlobo ezahlukene ze-waveguide ukuguqula phakathi kwezinhlobo ezahlukene ze-waveguide. Isibonelo:
1. Ama-waveguide kuya kuma-microstrip converters: Ama-waveguide kuya kuma-microstrip converters asetshenziswa kabanzi ekutholeni ama-millimeter wave monolithic integrated circuits kanye nama-hybrid circuits, kanye nasekuxhumeni kwama-waveguide kuya kuma-planar circuits ukuqinisekisa ukuguquka okufanelana kahle phakathi kwemigqa emibili yokudlulisela.
2. Ukushintsha kusuka kuma-waveguides anama-ridge amabili kuya kuma-waveguides angunxande: Ama-waveguides okushintsha asebenza ngomshini oqondile angaxhuma ama-waveguides anama-ridge amabili kuma-waveguides angunxande, anikeze ukulahlekelwa okuphansi kokufakwa kanye nokulingana okuphezulu. Lolu hlobo lwe-waveguides yokushintsha lufanele ukufakwa kwelabhorethri kanye nokulinganiswa kwe-waveguides enama-ridge amabili kanye nemishini.
3. Ukuguqulwa komhlahlandlela wamagagasi ongunxande: Umhlahlandlela wamagagasi ongunxande uguqula ngokufanayo imodi ye-TE10 kumhlahlandlela wamagagasi ongunxande ojwayelekile uye kumodi ye-TE11 kumhlahlandlela wamagagasi oyindilinga. Lokhu kuguqulwa kubalulekile ekudluliseni kahle amasignali kusuka kumhlahlandlela wamagagasi ongunxande ojwayelekile uye kumhlahlandlela wamagagasi oyindilinga, ikakhulukazi ezinhlelweni zokusebenza lapho kudingeka khona ukuguqulwa kwemodi ethile.

I-QualwaveUkuguqulwa kwe-waveguide yezinsiza kuhlanganisa ububanzi bemvamisa efika ku-220GHz, kanye nokuguqulwa kwe-waveguide eyenziwe ngokwezifiso ngokuya ngezidingo zamakhasimende.
