Dual directional loop coupler yog ib qho khoom siv microwave sib xyaw ua ke uas ua rau muaj kev sib kis tau zoo thiab sib txuas ntawm cov teeb liab hla sib txawv waveguides.

Tshwj xeeb, microwave dual directional voj coupler yog tsim los ntawm lub voj voog ncig thiab ntau qhov sib txuas ua ke waveguide. Los ntawm kev kho lub zog coupling ntawm lub coupling.
Waveguide thiab lub voj waveguide, lub zog taw qhia kev sib kis ntawm cov waveguide sib txawv tuaj yeem ua tiav. Cov ntsiab lus tseem ceeb ntawm lub voj voog kev taw qhia yog lub voj voog dielectric, feem ntau yog tsim los ntawm cov tubular lossis daim ntawv zoo li thaiv, nrog cov kab microstrip ncig hauv lub thaiv. Thaum lub teeb liab ntau zaus nkag mus rau lub annular dielectric thaiv los ntawm ib qho ntawm cov chaw nres nkoj, nws yuav maj mam hloov mus raws txoj kev ncig hauv lub sijhawm luv luv thiab nws thiaj li muab faib rau lwm qhov chaw nres nkoj. Thaum lub sij hawm hloov cov txheej txheem, vim yog cov yam ntxwv resonance ntawm lub dielectric thaiv thiab txoj kev ruaj khov ntawm lub voj voog, qhov sib txawv ntawm cov theem hloov tau raug tswj xyuas ntawm ib ncig ntawm 90 degrees, ua tiav kev faib hluav taws xob.

Daim ntawv thov:

Dual directional loop couplers yog dav siv nyob rau hauv microwave kev sib txuas lus, radar systems, satellite kev sib txuas lus, kav hlau txais xov arrays, thiab lwm yam teb. Ntawm lawv, daim ntawv thov hauv kev sib txuas lus wireless tshwj xeeb yog qhov dav, xws li 3G, 4G, 5G mobile kev sib txuas lus thiab WLAN tes hauj lwm, nrog rau kev tshawb nrhiav radar thiab tshaj tawm TV.

Yam ntxwv:

Piv nrog rau cov tsoos 180 degree directional couplers, broadband dual directional voj coupler muaj qhov zoo xws li cov bandwidth dav, qhov poob qis, me me ntim thiab loj, thiab kev tsim khoom yooj yim dua thiab kev sib koom ua ke. Qhov tsis zoo yog tias kev tswj xyuas qhov siab yuav tsum tau ua thaum lub sijhawm tsim khoom, thiab tseem yuav muaj teeb meem xws li theem tsis txaus thiab lub zog hloov pauv thaum lub sijhawm ua haujlwm. Yog li ntawd, kev tsim tshwj xeeb thiab kev ntsuas yog xav tau rau kev hloov kho thiab them nyiaj.

Qualwavemuab broadband thiab siab zog dual directional voj couplers nyob rau hauv ib tug ntau yam ntawm 1.72 mus rau 18GHz. Cov couplers tau dav siv hauv ntau daim ntawv thov.
