Incamake y'ibicuruzwa
Iyi sosiyete yacu ifite ubushobozi bwo kwakira amakuru bwa CATV network optique receiver SR814ST, pre-amplifier ikoresha GaAs MMIC yuzuye, naho post-amplifier ikoresha module za GaAs. Ifite imiterere myiza ya circuit hamwe n'uburambe bw'imyaka 10 mu gushushanya, iyi mashini imaze kugera ku bipimo by'imikorere myiza. Byongeye kandi, kugenzura microprocessor na digital parameters ecran bituma gukosora amakosa mu buhanga byoroha cyane. Ni byo bikoresho by'ingenzi bikenewe mu kubaka network ya CATV.
Ibiranga Imikorere
Umuyoboro wacu wa CATV ugezweho wakira urumuri SR814ST ukoresha umuyoboro wa PIN uhindura urumuri, utunganya imiterere y'uruziga n'imikorere ya SMT, kandi ugatuma ibimenyetso by'amashanyarazi bikwirakwira neza kandi mu buryo bworoshye.
Udupira twa RF twagenewe kugabanya umuvuduko w'amajwi dutanga uburyo bwo kugabanya umuvuduko w'amajwi neza, mu gihe ibikoresho byacu bya GaAs amplifier bitanga ubushobozi bwo kwiyongera cyane no kugabanya umuvuduko w'amajwi. Sisitemu igenzurwa na mudasobwa ntoya ifite utwuma duto (SCM), ifite ibipimo byo kwerekana LCD, imikorere yoroshye kandi isobanutse, hamwe n'imikorere ihamye.
Sisitemu ya AGC igenzura ko urwego rw'umusaruro rugumaho mu buryo buhamye ku ngufu za optique kuva kuri -9 kugeza kuri +2 dBm nta ngaruka mbi ziturutse kuri CTB na CSO. Sisitemu kandi ikubiyemo uburyo bwo gutumanaho bw'amakuru bwihariwe, bushobora guhuzwa n'igikoresho cyo gucunga umuyoboro wa kabiri kandi bugahuzwa na sisitemu yo gucunga umuyoboro. Ibipimo byose bya tekiniki bipimwa hakurikijwe GY/T 194-2003, hakurikijwe ibipimo bisanzwe by'ibizamini.
