Ma RF dual directional crossguide couplers omwe ali mu mtundu wa waveguide cross coupler, ali ndi specific of dual directionality.

Cholumikizira cha ma microwave cholumikizira mbali ziwiri nthawi zambiri chimakhala ndi ma waveguide awiri ozungulira wina ndi mnzake. Pamene mafunde amagetsi mu waveguide imodzi afika ndikudutsa pamalo olumikizirana, amatumizidwa ku waveguide ina. Munjira iyi, chifukwa malo olumikizirana pakati pa ma waveguide ali ndi ngodya inayake, gawo la mphamvu limatumizidwa ku waveguide ina, motero kukwaniritsa kulumikizana. Njira yotumizira iyi imatha kutumiza nthawi imodzi ma orthogonal modes awiri, kotero cholumikizira cha bi directional crossguide chimakhala ndi orthogonality yapamwamba.

Kugwiritsa ntchito cholumikizira cha broadband champhamvu kwambiri cha mbali ziwiri:

Ma broadband dual directional crossguide couplers amagwiritsidwa ntchito kwambiri poyesa ma microwave, kupanga zitsanzo, kuzindikira mphamvu zambiri, makina odyetsera ma microwave, radar, kulumikizana, kuyenda, kulumikizana ndi satellite ndi machitidwe ena.
Pankhani yolumikizirana, ma microwave dual directional crossguide couplers angagwiritsidwe ntchito kutulutsa ma microwave signals kuchokera ku waveguide imodzi ndikuyiphatikiza mu waveguide ina, zomwe zimapangitsa kuti pakhale kulumikizana pakati pa ma frequency band osiyanasiyana. Mwachitsanzo, mu machitidwe olumikizirana a satellite, ma millimeter wave dual directional crossguide couplers angagwiritsidwe ntchito kuphatikiza ma output ports a amplifiers pamlingo uliwonse, zomwe zimapangitsa kuti kutumiza ma signal pakati pa milingo kukhale kolondola komanso kodalirika. Kuphatikiza apo, ma radio frequency dual directional crossguide couplers angagwiritsidwenso ntchito kupanga ma network a two-dimensional kapena three-dimensional mu optics.

Makhalidwe a cholumikizira cha crossguide cholumikizira cha maulendo awiri pafupipafupi:

Pali mitundu yodziwika bwino ya ma waveguide monga rectangle, flat rectangle, medium flat rectangle, ndi double ridge, zomwe zimakhala ndi mawonekedwe a high directionality, low VSWR, low frequency response, ndi full wave conduction band width.

Qualwaveimapereka ma couplers amphamvu kwambiri okhala ndi ma waveguide awiriawiri osiyanasiyana kuyambira 2.6GHz mpaka 50.1GHz. Ma couplers amagwiritsidwa ntchito kwambiri m'njira zambiri. Zipangizo zoyambira za ma waveguide high directional couplers ndi zamkuwa ndi aluminiyamu, zomwe zimakhala ndi zinthu monga siliva, golide, nickel, passivation, ndi conductive oxidation. Miyeso yakunja, flange, mtundu wa joint, zinthu, chithandizo cha pamwamba, ndi zofunikira zamagetsi za ma waveguide couplers zitha kusinthidwa malinga ndi zosowa za ogwiritsa ntchito.
