Masu Canja Tsarin Lokaci Mai Sarrafa Na Dijital

Masu Canja Wuri Masu Sarrafawa ta Hanyar Dijital sune na'urori waɗanda ke daidaita yanayin siginar microwave ta hanyar sarrafa dijital. Babban ƙa'idar ita ce amfani da fasahar sarrafa siginar dijital don yin samfuri da ƙididdige siginar analog ko siginar dijital, sannan a canza ta zuwa dijital. Sannan ana motsa matakin siginar ta hanyar na'urar sarrafa siginar dijital. Manyan fihirisa sun haɗa da kewayon mitar aiki, kewayon lokaci, bits na sarrafawa, madaidaicin lokaci, daidaiton lokaci, asarar shigarwa, rabon tsayin ƙarfin lantarki, ƙarfin wutar lantarki da sauransu.

Siffofinsu sun haɗa da:

1. Babban matakin sarrafa kansa: ana iya tsara shi ko kuma ana iya sarrafa shi ta hanyar haɗin kwamfuta, ba tare da sa hannun hannu ba, yana inganta aminci da kwanciyar hankali na tsarin. A wannan yanayin, a matsayin na'urar jihohi biyu, mai canza yanayin sarrafawa na dijital yana da matakai daban-daban na sakawa a wurare daban-daban da kuma mitoci na microwave.
2. Ana iya kiyaye matakin lebur koda a kan manyan bandwidths..
3. Ko da an gina na'urar sauya yanayin dijital a cikin hanyar sadarwa mai ƙarancin daidaiton impedance, ba abu ne mai sauƙi ba a yi amfani da ita wajen jan hankali.
4. hayaniya a layin sarrafawa ba ta shafi shi ba.
5. daidaita iko mafi girma da kuma layi.

Saboda halayen da ke sama, ana amfani da Digital Step Phase Shifter sosai a fannin sadarwa, radar, auna mitar rediyo, kayan aikin soja, da sauransu, tare da waɗannan umarnin aikace-aikacen:

1. Samar da bambancin lokaci mai sarrafawa don siginar RF
2. Canja kusurwar lokacin watsawa na hanyar sadarwa mai tashoshi biyu
3. Ana sarrafa matakin eriya mai tsari na radar da kuma hanyar sadarwa mai sarrafawa ta alkibla. Ana sarrafa matakin kusanci na kowane abu na madaurin kawar da na'urar ƙara girman layi.
4. Tsarin haske.
5. Soke sigina.
