    Mawonekedwe:

    • Broadband
    • Mphamvu Yaikulu Yosinthasintha
    • Kusintha Komwe Kukufunika

    Mapulogalamu:

    • Opanda zingwe
    • Rada

    Digital Controlled Attenuator ndi gawo la microwave lomwe lingathe kuwongolera kuchuluka kwa kuchepetsedwa kwa mphamvu kudzera mu zizindikiro za digito.

    Mfundo yake yogwiritsira ntchito ndikuwongolera kuchepa kwa chizindikiro mwa kusintha momwe gawo lamkati kapena kukula kwa chizindikiro cholowera, kusintha mtengo wotsutsa. Poyerekeza ndi zochepetsera zamakina zachikhalidwe ndi zotsutsana zosinthika.

    Ma attenuator olamulidwa ndi digito ali ndi ubwino wotsatira:

    1. Kulondola kwambiri: Chochepetsera mphamvu ya digito chimatha kuwongolera bwino kwambiri kuchepetsedwa kwa mphamvu kudzera mu kulamulira kwa digito, nthawi zambiri kufika pa 0.1dB kapena kuchepera.
    2. Broadband: Zipangizo zochepetsera mawilo za digito nthawi zambiri zimagwira ntchito mu GHz kapena THz ndipo zimakhala ndi bandwidth yotakata.
    3. Large dynamic range: Digital Step attenuator imatha kukwaniritsa kusintha kwa 0dB mpaka 60dB kapena kupitirira apo, ndipo kusintha kwa mtunda ndi kwakukulu.
    4. Kuwongolera kosinthika: Chochepetsera mphamvu chowongolera cha digito chikhoza kukonzedwa kudzera mu ma interface a digito monga SPI ndi I2C, ndi kusinthasintha kwakukulu.

    Zochepetsera zamagetsi zoyendetsedwa ndi digito zimagwiritsidwa ntchito makamaka m'magawo monga kuyesa kwa microwave, radar, kulumikizana, ndi kulumikizana kwa satellite. Potengera pulogalamu yoyesera mwachitsanzo, chochepetsera zamagetsi chowongolera zamagetsi chingagwiritsidwe ntchito kusintha mphamvu ya chizindikiro choyesera kuti chiyese kukhudzidwa ndi kulumikizana kwa DUT (Chida Choyesedwa); Chingagwiritsidwe ntchito kulinganiza makina oyesera kuti chitsimikizire kulondola kwake ndi kusinthasintha kwake; Chingagwiritsidwe ntchito poyesa zochitika zoyeserera kuti chiwunikire magwiridwe antchito otsutsana ndi kusokoneza kwa makina motsutsana ndi mikhalidwe yosiyanasiyana ya kusokoneza ndi njira.

    Qualwaveimapereka ma attenuator olamulidwa ndi digito okhala ndi band yayikulu komanso ma dynamic range apamwamba pa ma frequency mpaka 50GHz. Sitepe ikhoza kukhala 10dB ndipo ma attenuation range akhoza kukhala 110dB kapena kuposerapo. Ma attenuator athu olamulidwa ndi digito ali ndi khalidwe labwino komanso kudalirika kwambiri, Ali ndi manambala opitilira 70, omwe angakwaniritse zosowa za makasitomala osiyanasiyana ndipo amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana.
