RF waveguides yog cov khoom siv uas xa lub zog ntawm ib qho mus rau lwm qhov. Tsis txhob siv hluav taws xob ncaj qha mus rau tag nrho qhov chaw zoo li lub kav hlau txais xov, lub microwave waveguide tuaj yeem kaw lub zog hauv cov hlau hollow, uas txo qhov poob thaum lub zog xa mus. Lub millimeter nthwv dej waveguide tuaj yeem nkag siab tias yog lub kav hlau txais xov muaj zog tshwj xeeb, thiab lub zog tsuas tuaj yeem nthuav tawm hauv lub waveguide, thiab tsis tuaj yeem tawm mus rau lwm qhov.
Waveguide kev hloov pauv yog ib qho ntawm cov waveguide, dav siv nyob rau hauv ntau qhov chaw, suav nrog tab sis tsis txwv rau microwave kev sib txuas lus, radar systems, kev sib txuas lus satellites thiab microwave xov tooj cua txuas khoom. Muaj ntau ntau hom kev hloov pauv, feem ntau muaj kev ua haujlwm siab, raug sawv nthwv dej VSWR≤1.2 nyob rau hauv tag nrho cov waveguide bandwidth, cov ntaub ntawv yooj yim suav nrog tooj liab, txhuas, cov txheej txheem kho deg nyiaj plating, kub plating, npib tsib xee plating, passivation, conductive oxidation, thiab lwm yam.

Qhov tshwj xeeb ntawm kev hloov pauv waveguide yog tias ob qhov chaw nres nkoj siv ntau hom waveguide rau kev hloov pauv ntawm ntau hom waveguide. Piv txwv li:
1. Waveguide rau microstrip converters: Waveguide rau microstrip converters yog dav siv nyob rau hauv lub nrhiav kom tau ntawm millimeter yoj monolithic integrated circuits thiab hybrid circuits, raws li zoo raws li nyob rau hauv kev twb kev txuas ntawm waveguide rau planar circuits los xyuas kom meej ib tug zoo-matched kev hloov ntawm ob kab kis.
2. Kev hloov los ntawm ob-ridged waveguides mus rau lub voj voog waveguides: Precision machined hloov waveguides tuaj yeem txuas ob-ridged waveguides rau rectangular waveguides, muab qhov qis qis qis thiab sib txuam siab. Hom kev hloov pauv waveguide no yog tsim rau kev sim teeb tsa thiab ntsuas ntawm ob-ridged rectangular waveguide sib dhos thiab cov khoom siv
3. Rectangular waveguide hloov: Lub voj voos waveguide uniformly converts TE10 hom nyob rau hauv ib tug qauv rectangular waveguide rau TE11 hom nyob rau hauv ib ncig waveguide. Qhov kev hloov dua siab tshiab no yog qhov tseem ceeb rau kev xa xov zoo los ntawm tus qauv duab plaub waveguide mus rau lub voj voog ncig, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov kev hloov pauv tshwj xeeb no yuav tsum tau ua.

Qualwavecov khoom siv waveguide hloov pauv npog qhov ntau zaus mus txog 220GHz, nrog rau kev hloov pauv hloov pauv raws li cov neeg siv khoom xav tau.
