Ma coupler awiri olowera pawiri amtundu wa waveguide cross coupler, ali ndi mayendedwe apawiri.

Ma waveguide cross coupler nthawi zambiri amakhala ndi ma coplanar waveguide omwe amayenderana. 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 ma waveguide cross coupler ali ndi digiri yayikulu ya orthogonality.

Ntchito:

Chogulitsacho chimagwiritsidwa ntchito kwambiri poyezera ma microwave, sampuli, kuzindikira kwamphamvu kwambiri, makina odyetsera ma microwave, radar, kulumikizana, kuyenda, kuyankhulana kwa satellite ndi machitidwe ena.
Pankhani yolumikizirana, ma waveguide cross 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, m'makina olankhulirana a satellite, ma waveguide cross couplers atha kugwiritsidwa ntchito kuphatikiza madoko a amplifiers pamlingo uliwonse, kupangitsa kufalikira kwa siginecha pakati pamilingo yolondola komanso yodalirika. Kuphatikiza apo, ma waveguide cross couplers amathanso kugwiritsidwa ntchito popanga ma network amitundu iwiri kapena atatu mu optics.

Makhalidwe:

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 burodibandi ndi mphamvu zapamwamba zapawiri zowongolera ma crossguide couplers osiyanasiyana kuchokera ku 5.38GHz mpaka 40GHz. 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.
