Tsawg VSWR Waveguide Variable Attenuators
Waveguide Variable Attenuators
Hauv microwave circuits, lub zog ntawm cov teeb liab feem ntau yog siab heev. Yog tias lub zog ntau dhau tsis tuaj yeem tswj tau tag nrho, nws yuav yooj yim ua rau muaj ntau yam teeb meem hauv Circuit Court, xws li ntau tshaj qhov siab tshaj ntawm lub zog siab ntawm cov khoom siv hluav taws xob thiab ua rau muaj ntau yam sib txawv. Kev siv cov waveguide attenuators tuaj yeem ua tau raws li qhov kev thov kom txo cov teeb liab lub zog thiab ua kom lub cev ua haujlwm ntawm microwave circuits.
Lub hauv paus ntsiab lus ua haujlwm ntawm waveguide attenuator yog ua raws li cov yam ntxwv ntawm kev nthuav tawm ntawm electromagnetic tsis nyob rau hauv waveguides. Nws feem ntau muaj cov waveguides, impedance txuam cov khoom, thiab cov neeg xyuas pib sib txawv. Thaum lub teeb liab hla dhau lub waveguide, ib feem ntawm lub zog yog absorbed los ntawm tus neeg xyuas pib thaiv, yog li txo cov teeb liab lub zog.
Thaum tus neeg xyuas pib thaiv yog cov qauv siv tshuab uas tuaj yeem hloov kho manually los ntawm tus neeg siv, nws yog lub waveguide sib txawv attenuators. Lub waveguide variable attenuators yog cov pab tsis tau hauv kev sib txuas lus hauv hluav taws xob.
Daim ntawv thov:
1. Los xyuas kom meej qhov sib npaug ntawm cov teeb liab theem nyob rau hauv cov teeb liab saw, waveguide manually adjustable attenuators yuav ua tiav los ntawm kev txo cov teeb liab zog.
2. Nthuav cov dynamic ntau yam ntawm lub system kuj yog ib tug muaj zog point ntawm lub waveguide manually adjustable attenuator, uas yuav ua kom ruaj khov kev khiav hauj lwm ntawm lub system.
3. Muab impedance txuam tuaj yeem zam qhov teeb meem kev xav thiab poob, ua kom muaj kev ruaj ntseg ntawm cov teeb liab kis tau tus mob.
Lub waveguide variable attenuator yog dav siv nyob rau hauv microwave kev sib txuas lus thiab kev sim kuaj. Nws tuaj yeem siv los kho cov teeb liab lub zog kom tau raws li qhov xav tau sib txawv. Piv txwv li, hauv chav kuaj, waveguide variable attenuator tuaj yeem muab kev hloov pauv hloov tau thaum lub teeb liab lub zog yuav tsum tau hloov mus rau kev ntsuas cov cuab yeej ua haujlwm. Hauv kev sib txuas lus hauv microwave, waveguide variable attenuators tuaj yeem siv los kho cov teeb liab lub zog kom ntseeg tau tias cov teeb liab tsis muaj zog dhau los yog tsis muaj zog thaum lub sijhawm sib kis.
Qhov zoo ntawm waveguide kuj tsis paub meej attenuators yog simplicity, yooj yim ntawm kev siv, thiab hloov tau yooj yim. Los ntawm kev tuav haujlwm, cov neeg siv tuaj yeem tswj hwm tus nqi ntawm cov teeb liab attenuation raws li xav tau. Txawm li cas los xij, piv rau cov tsis siv neeg waveguide attenuators, qhov kev hloov pauv ntawm phau ntawv waveguide attenuators yuav nqaim dua, thiab cov txheej txheem hloov kho yuav tsum muaj qee lub sijhawm thiab raug.
Qualwavekhoom siv qis VSWR thiab siab attenuation flatness ntawm 0.96 txog 110GHz. Lub attenuation ntau yog 0 ~ 30dB.
