Broadband Siab Hwj Chim Tsawg Ntxig Poob Ib Txoj Kev Qhia Broadwall Couplers

Lub waveguide directional coupler muaj lub ntsiab waveguide thiab ib tug tsis zoo waveguide. Coupling yog nqa tawm los ntawm cov coupling qhov ntawm cov phab ntsa ntawm lub ntsiab waveguide thiab lub auxiliary waveguide. Raws li tus naj npawb thiab cov duab ntawm lub qhov sib txuas, waveguide directional couplers tuaj yeem muab faib ua ntau yam qauv xws li ib lub qhov taw qhia kev sib txuas, ntxeem tau ntawm qhov sib txuas, hla lub qhov taw qhia txuas txuas nrog ob npaug T thiab waveguide tawg txuas hniav.
Ib qho kev taw qhia txuas txuas yog plaub qhov chaw nres nkoj uas suav nrog lub davhlau ya nyob twg input, lub davhlau ya nyob twg, lub davhlau ya nyob twg txuas, thiab lub davhlau ya nyob twg. Directional couplers yog passive thiab reversible networks. Nyob rau hauv txoj kev xav, cov kev taw qhia txuas txuas yog qhov tsis muaj hluav taws xob tsis zoo, thiab lawv cov chaw nres nkoj yuav tsum tau sib phim. Directional couplers tuaj yeem tsim los ntawm coaxial, waveguide, microstrip, thiab stripline circuits.
