Waveguide-rau-Coaxial Adapter: Lub Ntsiab Cai Ua Haujlwm, Hom & Phau Ntawv Qhia Xaiv

A waveguide-rau-coaxial adaptertxuas ib lub rectangular waveguide interface rau ib lub coaxial RF interface thaum khaws cia lub teeb liab kom zoo thoob plaws ib qho zaus band. Nws feem ntau yog siv thaum ib lub system yuav tsum txuas waveguide-fed antennas, cov khoom siv kuaj, radar modules, transmitters, receivers lossis lwm yam microwave Cheebtsam rau coaxial cables thiab connectors.

Lub adapter qee zaum hu ua waveguide converter, coaxial-to-waveguide adapter lossis waveguide transition. Hauv feem ntau cov qauv tsim passive, qhov kev hloov pauv yog reciprocal, yog li tib lub Cheebtsam tuaj yeem hloov lub zog los ntawm kab coaxial mus rau waveguide lossis los ntawm waveguide mus rau kab coaxial. Qhov kev xaiv zoo nyob ntawm qhov zaus band, qhov loj ntawm waveguide, flange, connector, layout, lub zog thiab kev ua haujlwm hluav taws xob.

Waveguide-rau-Coaxial Adapter Yog Dab Tsi?

Ib txoj hlua coaxial feem ntau txhawb nqa hom transverse electromagnetic, thaum lub waveguide rectangular feem ntau ua haujlwm hauv hom waveguide tseem ceeb xws li TE10. Ob lub qauv kis no muaj kev faib tawm teb sib txawv thiab impedances. Ib lub waveguide-rau-coaxial adapter muab kev hloov pauv tswj hwm ntawm lawv.

Sab waveguide muaj xws li lub qhov qhib thiab flange ntawm waveguide uas tau teev tseg. Sab coaxial muaj xws li lub qhov txuas RF thiab lub qhov hluav taws xob nruab nrab. Sab hauv qhov kev hloov pauv, lub probe lossis cov qauv txuas mus rau hauv waveguide ntawm qhov chaw xaiv zoo. Nws cov geometry, qhov tob nkag mus thiab qhov deb ntawm backshort tau ua kom zoo dua los sib txuas lub zog kom zoo thiab txo cov kev cuam tshuam.

Vim tias qhov kev hloov pauv yog qhov rhiab heev rau zaus, lub adapter yuav tsum tsis txhob xaiv los ntawm hom connector nkaus xwb. Yuav tsum kuaj xyuas qhov band ua haujlwm thiab lub npe waveguide ua ntej.

Lub Waveguide-rau-Coaxial Adapter Ua Haujlwm Li Cas?

Thaum lub teeb liab nkag los ntawm lub coaxial connector, tam sim no ntawm lub conductor nruab nrab ua rau lub coupling probe hauv waveguide zoo siab. Lub probe tso tawm cov qauv electromagnetic field uas xav tau, thiab lub backshort pab tsim kom muaj kev sib raug zoo ntawm theem kom zoo rau kev hloov pauv fais fab zoo. Hauv qhov kev taw qhia rov qab, lub waveguide field ua rau lub teeb liab hauv lub probe thiab xa nws mus rau kab coaxial.

Kev ua tau zoo yuav tsum tau muaj qhov sib phim ntawm lub zog hluav taws xob, qhov chaw ntawm lub probe thiab qhov ntev ntawm waveguide hla qhov ntau zaus uas xav tau. Yog tias lub adapter siv sab nraum nws qhov band uas tau teev tseg, lossis yog tias lub flange thiab connector interfaces tsis tau sib dhos zoo, qhov poob rov qab tuaj yeem puas tsuaj thiab qhov poob ntxig tuaj yeem nce ntxiv.
