RF dual directional crossguide couplers amtundu wa waveguide cross coupler, ili ndi mayendedwe apawiri.

Ma microwave dual directional crossguide coupler nthawi zambiri amakhala ndi ma coplanar waveguide perpendicular kwa wina ndi mzake. Pamene mafunde a electromagnetic mu waveguide imodzi afika ndikudutsa podutsa, amatumizidwa ku njira ina. Pochita izi, chifukwa malo odutsa pakati pa ma waveguide amakhala ndi ngodya inayake, gawo la mphamvu limatumizidwa ku njira ina yolumikizira, potero amakwaniritsa kulumikizana. Njira yopatsirayi imatha kufalitsa nthawi imodzi mitundu iwiri ya orthogonal, kotero kuti bi directional crossguide coupler imakhala ndi digiri yayikulu ya orthogonality.

Kugwiritsa ntchito kwa Broadband high power dual directional crossguide coupler:

Broadband dual directional crossguide couplers amagwiritsidwa ntchito kwambiri poyezera ma microwave, sampuli, kuzindikira zamphamvu kwambiri, makina odyetsera ma microwave, radar, kulumikizana, kuyenda, kuyankhulana kwa satellite ndi machitidwe ena.
Pankhani yolumikizirana, ma microwave dual directional crossguide couplers atha kugwiritsidwa ntchito kutulutsa ma siginecha a microwave kuchokera ku waveguide imodzi ndikuwaphatikiza mu waveguide ina, ndikukwaniritsa kulumikizana pakati pa ma frequency osiyanasiyana. Mwachitsanzo, mumakina olumikizirana ma satellite, ma millimeter wave dual directional crossguide couplers atha kugwiritsidwa ntchito kuphatikiza madoko otulutsa amplifiers pamilingo yonse, kupangitsa kufalikira kwa siginecha pakati pamilingo yolondola komanso yodalirika. Kuphatikiza apo, ma radio frequency dual directional crossguide couplers atha kugwiritsidwanso ntchito kupanga ma network awiri kapena atatu-dimensional network mu optics.

Mawonekedwe a ma frequency apamwamba a dual directional crossguide coupler:

Pali mitundu yodziwika bwino ya ma waveguide monga amakona anayi, amakona anayi, apakati amtundu wa rectangular, ndi mtunda wapawiri, womwe uli ndi mawonekedwe amayendedwe apamwamba, otsika VSWR, kuyankha kwafupipafupi, komanso kufalikira kwa band yozungulira.

Qualwaveimapereka ma Broadband high power dual directional crossguide couplers osiyanasiyana kuchokera ku 2.6GHz mpaka 50.1GHz. Ma couplers amagwiritsidwa ntchito kwambiri m'ma applications ambiri.Zinthu zoyambira ma waveguide high directional couplers ndi zamkuwa ndi aluminiyamu, zokhala ndi mankhwala apamtunda monga plating siliva, golide plating, nickel plating, passivation, ndi conductive oxidation. Miyeso yakunja, flange, mtundu wolumikizana, zakuthupi, chithandizo chapamwamba, ndi mawonekedwe amagetsi a ma waveguide couplers amatha kusinthidwa malinga ndi zosowa za ogwiritsa ntchito.
