Digital Controlled Attenuators
Digital Controlled Attenuator dia singa microwave izay afaka mifehy ny habetsaky ny attenuation amin'ny alàlan'ny famantarana nomerika.
Ny fitsipiky ny fampiharana azy dia ny fanaraha-maso ny fihenan'ny famantarana amin'ny alàlan'ny fanitsiana ny toetry ny singa anatiny na ny haben'ny famantarana fampidirana, manova ny sandan'ny fanoherana.Raha ampitahaina amin'ny attenuators mekanika mahazatra sy resistors miovaova.
Ny attenuators voafehy nomerika dia manana tombony manaraka:
1. High precision: Ny attenuator fanaraha-maso nomerika dia afaka manatratra ny fanaraha-maso avo lenta amin'ny alàlan'ny fanaraha-maso nomerika, matetika mahatratra ny marina amin'ny 0.1dB na latsaka.
2. Tarika fanamafisam-peo: Mazàna miasa ao amin'ny GHz na THz ny attenuators voafehy nomerika ary manana bandwidth midadasika.
3. Large dynamic range: Ny attenuator fanaraha-maso dizitaly dia afaka mahatratra ny haavon'ny fanitsiana avy amin'ny 0dB ka hatramin'ny 60dB na mihoatra, ary midadasika ny haavon'ny fanitsiana.
4. Fanaraha-maso azo atao: Ny attenuator fanaraha-maso nomerika dia azo atao amin'ny alàlan'ny fifandraisana nomerika toy ny SPI sy I2C, miaraka amin'ny flexibility avo.
Ny attenuators fehezin'ny nomerika dia ampiasaina indrindra amin'ny sehatra toy ny fitiliana mikraoba, radar, fifandraisana ary fifandraisana amin'ny zanabolana.Raha raisina ho ohatra ny fampiharana fitsapana, ny attenuator fanaraha-maso nomerika dia azo ampiasaina hanitsiana ny herin'ny famantarana fitsapana mba handrefesana ny fahatsapana sy ny linearity ny DUT (Device Under Test);Azo ampiasaina amin'ny calibrate ny rafitra fitsapana mba hiantohana ny fahamarinany sy ny tsy fitoviana;Azo ampiasaina amin'ny sehatra fitiliana simulation izy io mba hanombanana ny fahombiazan'ny rafitra manohitra ny fitsabahana sy ny toetry ny fantsona.
Qualwavedia manome tarika midadasika sy avo lenta dynamique fehezin'ny attenuators nomerika amin'ny fatrany hatramin'ny 40GHz.Ny dingana dia mety ho 0.25dB ary mety ho 100dB na mihoatra.Ny attenuators nomerika voafehy dia manana kalitao tsara sy azo itokisana avo lenta, miaraka amin'ny isa mihoatra ny 70, izay mahafeno ny filan'ny mpanjifa samihafa ary ampiasaina betsaka amin'ny sehatra maro.
