Kugwiritsa ntchito Common Rectangular Waveguides, Flanges, ndi Waveguide Coaxial Converters

M'munda wa RF ndi ma microwave kufala kwa siginecha, kuwonjezera pa kufalitsa ma siginecha opanda zingwe, ambiri amafunikira mizere yotumizira ma siginecha, yokhala ndi mizere ya coaxial ndi ma waveguide omwe amagwiritsidwa ntchito kwambiri kufalitsa mphamvu ya microwave RF.

Mizere yotumizira ma Waveguide ili ndi zabwino zake zotayika kwa conductor ndi dielectric, mphamvu yayikulu, palibe kutayika kwa ma radiation, kapangidwe kosavuta, komanso kupanga kosavuta.Mafunde omwe amagwiritsidwa ntchito nthawi zambiri amaphatikiza ma rectangular, zozungulira, zopindika limodzi, zopindika pawiri, ndi elliptical.Pakadali pano, ma waveguide omwe amagwiritsidwa ntchito kwambiri ndi ma waveguide amakona anayi.

Pogwiritsa ntchito zida za waveguide, zida zingapo nthawi zambiri zimafunikira kulumikizidwa molingana, ndipo kulumikizana pakati pa zida zoyandikana ndi ma waveguide nthawi zambiri kumatheka kudzera mu kulumikizana komweko kwa flanges.

Monga zolumikizira za RF coaxial, ma waveguide wamba ndi ma flanges nawonso amakhazikika padziko lonse lapansi.Kupyolera mu tebulo ili m'munsimu, mukhoza kufunsa mayina ofanana ndi makulidwe amitundu yosiyanasiyana yamakona.

Kugwiritsa ntchito Waveguide Coaxial Converter

Momwemonso, mizere ya coaxial ndinso mizere yotumizira yomwe imagwiritsidwa ntchito kwambiri mu microwave ndi ma radio frequency engineering, okhala ndi mawonekedwe a Broadband omwe amatha kuyenda kuchokera pakali pano kupita ku millimeter wave band, kapena kupitilira apo.Mizere yotumizira ma coaxial imagwiritsidwa ntchito kwambiri pamakina onse a microwave ndi ma microwave.

 Pali kusiyana kwakukulu mu kukula, zinthu, ndi machitidwe opatsirana pakati pa mizere yopatsirana ya coaxial ndi waveguide.Komabe, chifukwa cha kuchuluka kwa ntchito zawo, mainjiniya a RF nthawi zambiri amakumana ndi zochitika zomwe mizere iwiri yotumizira imafunikira kulumikizidwa, zomwe zimafunikira ma coaxial waveguide converters.

Coaxial waveguide converters ndi zida zofunika pazida za microwave, muyeso wa microwave, makina a microwave, ndi engineering.Njira zawo zosinthira makamaka zimaphatikizapo kulumikiza mabowo ang'onoang'ono, kugwirizanitsa kafukufuku, kusintha kwa kusintha kwa mzere womaliza, ndi kutembenuka kwa ridge waveguide;Coaxial probe coupling ndi njira yosinthira yomwe imagwiritsidwa ntchito kwambiri pakati pawo.

The waveguide coaxial converter makamaka imakhala ndi chosinthira choyamba, chosinthira chachiwiri, ndi flange, chokhala ndi zigawo zitatu zolumikizidwa motsatana.Nthawi zambiri pamakhala ma orthogonal 90 ° waveguide coaxial converters ndi kuthetsedwa kwa 180 ° waveguide coaxial converters.Coaxial waveguide converter ili ndi mawonekedwe a frequency band, kutayika kotsika, komanso mawonekedwe ang'onoang'ono.Bandwidth ya coaxial line ndi waveguide ndi yotakata potumiza motsatana, ndipo bandwidth ikatha kulumikizidwa imadalira kufananiza kwa mawonekedwe a coaxial waveguide.

Coaxial waveguide conversion imagwiritsidwa ntchito kwambiri m'makina ambiri a microwave, monga tinyanga, ma transmitters, olandila, ndi zida zonyamula zonyamula, zomwe zitha kugwiritsidwa ntchito kwambiri polumikizana ndi satelayiti, radar, kulumikizana opanda zingwe, ma microwave aku mafakitale, kuyezetsa ndi kuyeza kwa microwave, machitidwe azachipatala a microwave. , ndi zina.
