Chidule cha Zamalonda
SR812ST-R ndiye makina athu aposachedwa kwambiri a CATV network optical receiver.Pre-amplifier imatenga Full-GaAs MMIC, post-amplifier imatenga gawo la GaAs.Mapangidwe okhathamiritsa ozungulira ophatikizidwa ndi zaka 15 za luso laukadaulo, zipangitsa kuti zidazo zizigwira bwino ntchito.Kuwongolera kwa Microprocessor, kuwonetsa kwa digito kwa magawo, kukonza zolakwika zaukadaulo ndikosavuta kwambiri.Ndi chida chachikulu chopangira netiweki ya CATV.
Makhalidwe Antchito
- Kuyankha kwakukulu kwa PIN yosinthira zithunzi zamagetsi.
- Mawonekedwe okhathamiritsa ozungulira, kupanga njira za SMT, ndi njira yokongoletsedwera yama siginecha imapangitsa kuti kufalitsa kwa siginecha yazithunzi kukhala kosavuta.
- Specialized RF attenuation chip, yokhala ndi RF attenuation yabwino komanso milingo yofananira, yolondola kwambiri.
- Chida cha amplifier cha GaAs, chotulutsa mphamvu zowirikiza kawiri, chopindula kwambiri komanso kusokonekera kochepa.
- Zida zowongolera za Single Chip Microcomputer (SCM) zikugwira ntchito, LCD imawonetsa magawo, kusavuta komanso kugwira ntchito mwanzeru, komanso magwiridwe antchito okhazikika.
- Kuchita bwino kwambiri kwa AGC, pamene mphamvu yamagetsi yolowetsamo ndi －9～＋2dBm, mulingo wotulutsa umakhala wosasinthika, ndipo CTB ndi CSO kwenikweni sizisintha.
- Mawonekedwe ochezera a data osungidwa, amatha kulumikizana ndi kalasi Ⅱ woyankha kasamalidwe ka netiweki, ndikupeza njira yoyendetsera maukonde.
- Kubwereranso kumatha kusankha njira yophulika kuti muchepetse kusinthika kwaphokoso ndikuchepetsa nambala yolandila kutsogolo.
