SR812ST-R ndi cholandirira chathu chaposachedwa cha CATV network optical chapamwamba kwambiri cha magawo awiri. Chotulutsira chisanadze chimagwiritsa ntchito full-GaAs MMIC, post-amplifier imagwiritsa ntchito GaAs module. Kapangidwe kabwino ka dera limodzi ndi zaka 15 zaukadaulo wathu wopanga, zimapangitsa kuti zidazi zikwaniritse ma index abwino a magwiridwe antchito. Kuwongolera ma microprocessor, kuwonetsa kwa digito kwa magawo, ndi kukonza zolakwika zaukadaulo ndikosavuta kwambiri. Ndi chipangizo chachikulu chomangira netiweki ya CATV.
Makhalidwe Ogwira Ntchito
- Chubu chosinthira mphamvu ya PIN yoyankhira kwambiri.
- Kapangidwe kabwino ka dera, kupanga njira za SMT, ndi njira yabwino kwambiri ya chizindikiro zimapangitsa kuti kutumiza chizindikiro cha photoelectric kukhale kosalala.
- Chip yapadera yochepetsera RF, yokhala ndi RF yabwino komanso yolondola, yolondola kwambiri.
- Chipangizo chowonjezera cha GaAs, chotulutsa mphamvu chowirikiza kawiri, chokhala ndi phindu lalikulu komanso kusokonekera kochepa.
- Zipangizo zowongolera za Single Chip Microcomputer (SCM) zikugwira ntchito, LCD imawonetsa magawo, kusavuta kugwiritsa ntchito komanso kugwiritsa ntchito mwanzeru, komanso magwiridwe antchito okhazikika.
- Kugwira ntchito bwino kwa AGC, pamene mphamvu yolowera ya kuwala ndi －9～＋2dBm, mulingo wotuluka susintha, ndipo CTB ndi CSO sizisintha kwenikweni.
- Mawonekedwe olumikizirana deta osungidwa, amatha kulumikizana ndi woyankha wa kasamalidwe ka netiweki wa kalasi Ⅱ, ndikupeza njira yoyendetsera netiweki.
- Kubweza mpweya kumatha kusankha njira yophulika kuti muchepetse phokoso kwambiri ndikuchepetsa nambala ya wolandila kutsogolo.
