IINKCUKACHA ZEMVELISO

Ingcaciso yeMveliso

I-GWE1000 yi-amplifier yokuhlala eneendleko ezininzi eyenzelwe indlela yeentsuku ezimbini ye-CATV kunye ne-Docsis 3.1 okanye i-Docsis 3.0 okanye i-Docsis 2.0 ye-modem ye-cable applications. Ngaphandle kokusasaza umgangatho ophezulu we-analog TV okanye i-DVB-C TV, i-GWE1000 ihlangabezana neemfuno zothungelwano lwanamhlanje olwandisiweyo lonxibelelwano olusekelwe kwi-CMTS kunye nobuchwepheshe bemodem yentambo. Indlela eya phambili iRF ine-37dB inzuzo exhasa ukuya kuthi ga kwi-48dBmV imveliso yeRF ngelixa indlela yokubuya ine-27dB inzuzo exhasa ukuya kuthi ga kwi-44dBmV indlela yokubuya yeRF. Idizayinelwe ufakelo lwenethiwekhi ye-HFC kwizakhiwo ezikwizindlu eziqeshisayo, esi sixhobo sokuhambisa isandisi-lizwi sangaphakathi esinengeniso ephezulu siyafumaneka sinomthamo wokuya kuthi ga kwi-1003MHz (i-1218MHz ngokuzikhethela) ukuze kuphuculwe ukusebenza kwenkqubo. Ngaphandle kwesiseko se-42/54MHz sokuqhekeka kwamatyeli, i-GWE1000 inokubonelela nge-85/102MHz okanye i-204/258MHz yokwahlulwa kwamaza okuphindaphinda kwiimfuno eziphambili zebroadband.

I-amplifier yemveliso enye ine-attenuator ehlengahlengisiweyo eqhubekayo kunye ne-equalizer eguquguqukayo eqhubekayo kuyo yomibini indlela eya phambili kunye nendlela yokubuya ye-RF yokuguquguquka okukhulu xa useta iamplifier. Iyunithi ibandakanya i-F-type input input kunye ne-output connector port port, -20dB indlela eya phambili kunye ne-20dB yokuvavanya indlela yokubuya. Ukuhlangabezana nesicelo sokwahluka kwizicelo zokuhlala kwi-mulit, zonke izibuko zeRF ze-GWE1000 ziyilelwe ukuba zibe nokhuseleko lwe-6KV.

I-GWE1000 isebenzisa amandla angaphantsi kwe-14W. Zonke iimodyuli ze-amplifier zifakwe kwi-sink enye ye-aluminium yokushisa. I-GWE1000 inesigubungelo sezindlu sentsimbi esinoshicilelo lwesilika olusebenzayo.
I-MDU ine-auto-ranging switching power supply, enokwamkela i-input voltages ukusuka kwi-90 ukuya kwi-240V kwi-frequencies ye-50 okanye i-60 Hz ngaphandle kohlengahlengiso.
