Digital Controlled Attenuators
Digital Controlled Attenuator yog ib qho microwave tivthaiv uas tuaj yeem tswj tus nqi qis los ntawm cov teeb liab digital.
Nws txoj hauv kev siv yog los tswj lub attenuation ntawm lub teeb liab los ntawm kev kho lub xeev ntawm cov khoom siv sab hauv lossis qhov loj ntawm cov teeb liab tawm tswv yim, hloov cov nqi tsis kam.Piv nrog rau cov tsoos mechanical attenuators thiab cov resistors sib txawv.
Digital tswj attenuators muaj qhov zoo hauv qab no:
1. High precision: Cov kev tswj hwm digital attenuator tuaj yeem ua tiav qhov kev tswj xyuas siab ntawm attenuation los ntawm kev tswj digital, feem ntau ncav cuag qhov tseeb ntawm 0.1dB lossis tsawg dua.
2. Broadband: Digital tswj attenuators feem ntau ua haujlwm hauv GHz lossis txawm tias THz ntau thiab muaj qhov dav bandwidth.
3. Loj dynamic ntau: Cov kev tswj hwm digital attenuator tuaj yeem ua tiav qhov kev hloov kho tau los ntawm 0dB mus rau 60dB lossis ntau dua, thiab qhov kev hloov kho tau dav.
4. Programmable tswj: Lub tshuab thev naus laus zis thev naus laus zis tuaj yeem tsim los ntawm kev sib cuam tshuam digital xws li SPI thiab I2C, nrog kev hloov pauv siab.
Digital tswj attenuators feem ntau yog siv hauv thaj chaw xws li kev ntsuas microwave, radar, kev sib txuas lus, thiab kev sib txuas lus satellite.Siv daim ntawv thov kev xeem ua piv txwv, lub tshuab thev naus laus zis thev naus laus zis tuaj yeem siv los kho lub zog ntawm cov teeb liab ntsuas los ntsuas qhov rhiab heev thiab linearity ntawm DUT (Device Under Test);Nws tuaj yeem siv los ntsuas qhov ntsuas qhov ntsuas kom ntseeg tau tias nws qhov tseeb thiab sib xws;Nws tuaj yeem siv rau kev simulation sim cov xwm txheej los ntsuas qhov kev cuam tshuam kev cuam tshuam ntawm lub kaw lus tiv thaiv kev cuam tshuam sib txawv thiab cov xwm txheej hauv channel.
Qualwavemuab broadband thiab siab dynamic ntau yam digital tswj attenuators ntawm zaus mus txog 40GHz.Cov kauj ruam yuav yog 0.25dB thiab attenuation range tuaj yeem yog 100dB lossis ntau dua.Peb cov kev tswj hwm digital attenuators muaj qhov zoo thiab muaj kev ntseeg siab, Muaj ntau tshaj 70 tus lej, uas tuaj yeem ua tau raws li qhov xav tau ntawm cov neeg siv khoom sib txawv thiab tau siv dav hauv ntau qhov chaw.
