Chidule Chachidule
SR812ST(R) ndi chipangizo chathu chaposachedwa kwambiri cha CATV network optical receiver chapamwamba kwambiri cha grade two-output. Pre-amplifier imagwiritsa ntchito full-GaAs MMIC, post-amplifier imagwiritsa ntchito GaAs module. Kapangidwe kabwino ka dera limodzi ndi zaka 10 zomwe takumana nazo popanga, zimapangitsa kuti zipangizozi 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, mphamvu yotulutsa kawiri, yokhala 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, komanso mwayi wopeza njira yoyendetsera netiweki.
- Kubweza mpweya kumatha kusankha njira yophulika kuti muchepetse phokoso kwambiri ndikuchepetsa nambala ya wolandila kutsogolo.
Mikhalidwe Yoyesera Ulalo
Magawo aukadaulo a bukuli malinga ndi njira yoyezera ya GY/T 194-2003
1. Gawo lolandila la Forward optical: lokhala ndi ulusi wowunikira wa 10km, chotenthetsera cha kuwala chopanda mphamvu, ndi chotumizira chowunikira chokhazikika chinapanga ulalo woyesera. Ikani chizindikiro cha TV cha analog cha 59 PAL-D pa mtunda wa 45/87MHz～550MHz pansi pa kutayika kwa ulalo womwe watchulidwa. Kutumiza chizindikiro cha digito pa mtunda wa 550MHz～862/1003MHz, mulingo wa chizindikiro cha digito (mu bandwidth ya 8 MHz) ndi wochepera 10dB kuposa mulingo wonyamula chizindikiro cha analog. Pamene mphamvu yolowera ya cholandirira kuwala ili -2dBm, mulingo wa RF output ndi 108dBμV, ndi 9dB output tilt, yesani C/CTB, C/CSO, ndi C/N.
2. Gawo lotumizira kuwala lakumbuyo: Kusalala kwa maulumikizidwe ndi mtundu wa NPR ndi ma index olumikizira omwe amapangidwa ndi chotumizira kuwala chakumbuyo ndi cholandirira kuwala chakumbuyo.
Dziwani: Ngati mulingo wotulutsa womwe wawerengedwa ndi wokhazikika pa dongosolo lonse ndipo mphamvu yolandira ndi -2dBm, chipangizocho chimakwaniritsa mulingo wokwanira wotulutsa wa chizindikiro cha ulalo. Pamene kasinthidwe ka dongosolo kachepa (ndiko kuti, njira zenizeni zotumizira zimachepa), mulingo wotulutsa wa zida udzawonjezeka.
Chidziwitso Chabwino: Perekani lingaliro loti muyike chizindikiro cha RF ku 6~9dB tilt output mu pulogalamu yothandiza ya uinjiniya kuti muwongolere chizindikiro chosakhala cha mzere (pansi pa node) cha dongosolo la chingwe.
