Ang prinsipyo ng pagpapatupad nito ay upang kontrolin ang pagpapalambing ng signal sa pamamagitan ng pagsasaayos ng estado ng panloob na bahagi o ang laki ng input signal, pagbabago ng halaga ng paglaban. Kumpara sa tradisyonal na mechanical attenuators at variable resistors.
1. Mataas na katumpakan: Ang digital control attenuator ay maaaring makamit ang mataas na katumpakan na kontrol ng attenuation sa pamamagitan ng digital na kontrol, kadalasang umaabot sa isang katumpakan na 0.1dB o mas mababa.
2. Broadband: Ang mga digital controlled attenuator ay karaniwang gumagana sa GHz o kahit na THz range at may malawak na bandwidth.
3. Malaking dynamic range: Ang digital control attenuator ay maaaring makamit ang isang adjustable range mula 0dB hanggang 60dB o higit pa, at ang adjustment range ay malawak.
4. Programmable control: Ang digital control attenuator ay maaaring i-program sa pamamagitan ng mga digital na interface tulad ng SPI at I2C, na may mataas na flexibility.
Pangunahing ginagamit ang mga digital controlled attenuator sa mga larangan tulad ng microwave testing, radar, komunikasyon, at satellite communication. Ang pagkuha ng test application bilang isang halimbawa, ang digital control attenuator ay maaaring gamitin upang ayusin ang kapangyarihan ng test signal upang masukat ang sensitivity at linearity ng DUT (Device Under Test); Maaaring gamitin upang i-calibrate ang sistema ng pagsubok upang matiyak ang katumpakan at pagkakapare-pareho nito; Maaari itong magamit para sa mga sitwasyon ng pagsubok sa simulation upang suriin ang pagganap ng anti-interference ng system laban sa iba't ibang interference at kundisyon ng channel.
Qualwavenagbibigay ng malawak na banda at mataas na dynamic range na kinokontrol na mga attenuator ng digital sa mga frequency hanggang 40GHz. Ang hakbang ay maaaring 0.25dB at ang attenuation range ay maaaring 100dB o higit pa. Ang aming mga digital na kinokontrol na attenuator ay may magandang kalidad at mataas na pagiging maaasahan, Na may higit sa 70 mga numero ng bahagi, na maaaring matugunan ang mga pangangailangan ng iba't ibang mga customer at malawakang ginagamit sa maraming larangan.
