    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 waveguide variable 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 kev hloov pauv tsis tu ncua attenuator yog raws li kev nthuav tawm cov yam ntxwv ntawm electromagnetic nthwv dej hauv waveguides. Nws feem ntau muaj cov waveguides, impedance txuam cov cuab yeej, 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 rotary stepped attenuators. Cov kev sib txawv ntawm cov attenuators yog qhov tseem ceeb 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 variable attenuators tuaj yeem 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 teb stepped attenuator, uas yuav ua tau 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 kuaj sim. Nws tuaj yeem siv los kho cov teeb liab lub zog kom tau raws li qhov xav tau sib txawv. Piv txwv li, nyob rau hauv lub chaw soj nstuam, cov kauj ruam teb tuaj yeem muab cov peev xwm hloov tau yooj yim 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, tsis tu ncua hloov pauv attenuators tuaj yeem siv los kho cov teeb liab lub zog kom ntseeg tau tias lub teeb liab tsis muaj zog dhau los yog tsis muaj zog thaum lub sijhawm sib kis.
    Qhov zoo ntawm qhov sib txawv 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.

    QualwaveCov khoom siv qis VSWR thiab siab attenuation flatness ntawm 0.96 txog 500GHz. Lub attenuation ntau yog 0 ~ 40dB.
