Incazelo Yomkhiqizo
Uhlolojikelele olufushane
I-SR812ST(R) isamukeli sethu sakamuva se-CATV senethiwekhi ye-CATV esikhiphayo senethiwekhi. I-pre-amplifier isebenzisa i-Full-GaAs MMIC, i-post-amplifier isebenzisa imojuli ye-GaAs. Idizayini yesekethe ethuthukisiwe ehambisana neminyaka engu-10 yesipiliyoni sokuklama kochwepheshe, yenza okokusebenza kufinyelele izinkomba zokusebenza ezinhle. Ukulawulwa kwe-Microprocessor, ukuboniswa kwedijithali kwemingcele, ukulungisa iphutha lobunjiniyela kulula kakhulu. Iwumshini omkhulu wokwakha inethiwekhi ye-CATV.
Izimpawu Zokusebenza
- I-PIN yokuphendula ephezulu yokuguqula isithombe sikagesi.
- Idizayini yesekethe ethuthukisiwe, ukukhiqizwa kwenqubo ye-SMT, kanye nendlela yesiginali eyenziwe kahle yenza ukudluliswa kwesiginali yezithombe kagesi kube bushelelezi.
- I-chip ye-RF eyisipesheli yokunciphisa, ene-RF attenuation enhle nokulingana ngomugqa, ukunemba okuphezulu.
- Idivayisi ye-amplifier ye-GaAs, amandla aphuma ngokuphindwe kabili, anenzuzo ephezulu kanye nokuhlanekezela okuphansi.
- Imishini yokulawula ye-Single Chip Microcomputer (SCM) esebenzayo, i-LCD ibonisa imingcele, ukusebenza okulula nokusebenza okunembile, nokusebenza okuzinzile.
- Ukusebenza okuhle kakhulu kwe-AGC, uma ububanzi bamandla okufakwayo bungu-－9～＋2dBm, izinga lokukhiphayo lihlala lingashintshiwe, futhi i-CTB ne-CSO empeleni azishintshile.
- Isixhumanisi esibonakalayo sokuxhumana kwedatha, singaxhuma nesiphenduli sokuphathwa kwenethiwekhi yekilasi Ⅱ, kanye nokufinyelela ohlelweni lokuphatha inethiwekhi.
- Ukukhishwa kokubuyisela kungakhetha imodi yokuqhuma ukunciphisa kakhulu ukuhlangana komsindo nokunciphisa inombolo yomamukeli ongaphambili.
Imibandela Yokuhlola Isixhumanisi
Imingcele yezobuchwepheshe yaleli bhukwana ngokwendlela yokulinganisa ye-GY/T 194-2003
1. Ingxenye yokwamukela i-optical yangaphambili: ene-fiber optical evamile engu-10km, i-passive optical attenuator, kanye nesidluliseli esijwayelekile sokukhanya sihlanganise isixhumanisi sokuhlola. Setha isignali ye-TV ye-analog engu-59 PAL-D ebangeni elingu-45/87MHz ~550MHz ngaphansi kokulahlekelwa kwesixhumanisi okucacisiwe. Dlulisa isignali yokushintshashintsha kwedijithali ebangeni elingu-550MHz ~862/1003MHz, ileveli yesiginali yokushintshashintsha kwedijithali (kumkhawulokudonsa ongu-8 MHz) ingaphansi ngo-10dB kuneleveli yenkampani yenethiwekhi ye-analog. Uma amandla okufaka okubonayo omamukeli obonakalayo engu- -2dBm, izinga lokuphumayo le-RF lingu-108dBμV, nokutsheka kokuphumayo okungu-9dB, kukala i-C/CTB, C/CSO, ne-C/N.
2. Ingxenye ye-Optical Transmit ebuyela emuva: Ukuvuleka kwesixhumanisi kanye nobubanzi obuguquguqukayo be-NPR yizinkomba zesixhumanisi ezakhiwe isidluliseli esingemuva esibonayo kanye nomamukeli obonayo obuyela emuva.
Qaphela: Uma izinga lokukhiphayo elilinganiselwe kuwukucushwa okugcwele kwesistimu futhi amandla okubona atholayo angu- -2dBm, okokusebenza kuhlangabezana nezinga eliphezulu lokuphumayo lenkomba yesixhumanisi. Lapho ukucushwa kwesistimu kunciphisa (okungukuthi, amashaneli angempela okudlulisela ancipha), izinga lokukhipha impahla lizokwenyuswa.
Isaziso Esinobungane: Phakamisa ukuthi usethe isignali ye-RF ibe ngu-6~9dB ophumayo onyakazayo ohlelweni lokusebenza lobunjiniyela ukuze uthuthukise inkomba engaqondile (ngaphansi kwenodi) yesistimu yekhebula.
