Lub waveguide voj coupler yog ib qho khoom siv microwave uas muaj lub voj voj voog thiab ob kab sib kis.

Qhov no microwave ib qho kev taw qhia lub voj txuas txuas yog tsuas yog siv rau bandpass filteloop thiab luv-circuit impedance txuam rau cov kab sib kis. Cov coupler no tuaj yeem hloov lub zog ntau zaus los ntawm ib txoj kab xa mus rau lwm qhov, yog li ua tiav cov kab txuas txuas.

Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm waveguide voj coupler feem ntau yog nyob ntawm ob yam: cov yam ntxwv ntawm lub voj voog txuas txuas thiab cov kab microstrip.Directional coupler yog hais txog lub zog faib nrog cov kev taw qhia.

Lub voj coupler yog ib qho tseem ceeb hauv waveguide voj couplers, uas feem ntau plays lub luag hauj lwm nyob rau hauv lub zog coupling.

Qhov no annular coupling muaj ob qhov nyob ib sab ib nrab voj voog, nrog ib nrab voj ua hauj lwm raws li qhov chaw nres nkoj input thiab lwm ib nrab voj ua hauj lwm raws li qhov chaw nres nkoj. Thaum lub teeb liab high-frequency ncav cuag lub annular coupling raws qhov chaw nres nkoj input, nws yuav kis mus rau ib nrab voj voog uas nyob ib sab. Nyob rau lub sijhawm no, vim muaj qhov sib nqus ntawm qhov sib nqus, lub teeb liab tseem yuav raug xa mus rau lwm qhov ib nrab voj voog, yog li ua tiav lub zog sib txuas. Thaum kawg, nws muaj peev xwm ua tau ob peb lub tswv yim teeb liab los ntawm qhov chaw nres nkoj input mus rau qhov chaw tso zis thaum ensuloop qib siab ntawm coupling efficiency.

Lub ntsiab kev ua tau zoo ntawm broadband ib leeg directional voj couplers

Cov ntsuas kev ua haujlwm tseem ceeb rau measuloop directional couplers suav nrog kev khiav hauj lwm ntau zaus, coupling degree (los yog kev hloov pauv), kev taw qhia, thiab kev tawm tswv yim / tso tawm sawv yoj piv.
1. Lub coupling degree yog hais txog qhov sib piv decibel ntawm lub zog input ntawm lub ntsiab waveguide mus rau lub zog tso zis ntawm qhov chaw nres nkoj coupling nyob rau hauv cov xwm txheej ntawm kev sib txuam load ntawm txhua qhov chaw nres nkoj.
2. Cov kev taw qhia yog hais txog qhov sib piv decibel ntawm cov zis hluav taws xob ntawm qhov chaw nres nkoj txuas mus rau lub zog tso tawm ntawm qhov chaw nres nkoj cais raws li qhov xwm txheej ntawm kev sib txuam ntawm txhua qhov chaw nres nkoj. Directional couplers yog dav siv rau cov teeb liab sampling nyob rau hauv lub hwj chim faib thiab microwave ntsuas.

Qualwavemuab broadband thiab siab zog ib leeg directional voj couplers nyob rau hauv ib tug ntau yam ntawm 2.6 mus rau 18GHz. Cov couplers tau dav siv hauv ntau daim ntawv thov.
