Kev piav qhia

GME's 1.2G amplifier yog tus nqi qis - tus nqi, siab - kev ntseeg tau, Compact Hauv qhov loj amplifier. Nws muaj qhov dav bandwidth thiab qib siab / siab txoj kab nqes tso zis muaj peev xwm uas xa cov kev ua tau zoo txhawb nqa DOCSIS 3.1 zaus rau 1.22GHz. Cov qauv tsim tshwj xeeb muaj kev teeb tsa rau 42 lossis 85 lossis 204MHz upstream bandwidth xav tau.

Cov ntawv thov amplifier rau sab hauv tsev siab HFC network kev teeb tsa hauv cov tsev tsev, tsev so, tsev kawm ntawv, tsev kho mob ..., muaj RF amplification siab. Tsim los nrog kev nce qib siab no lub tshuab hluav taws xob tuaj yeem txuas ncaj qha mus rau phab ntsa nrog cov khoom siv hluav taws xob ntau ntxiv thiab siv hluav taws xob tsawg.

Qhov no CATV Amplifier Rau Lub Tsev siv qhov tseeb 1.22GHz GaAs Push Pull thev naus laus zis versions muab kev ua tau zoo tshaj qhov tsis sib haum xeeb thiab tsis tshua muaj suab nrov.

Tus kws tshaj lij tus phooj ywg tswj hwm cov yam ntxwv sib txawv ntawm cov attenuators thiab cov sib npaug sib npaug ua kom yooj yim dua thaum kho lub amplifier. Lub zog hluav taws xob sab hauv lees txais cov khoom siv hluav taws xob los ntawm 100-240V ntawm zaus ntawm 50 lossis 60Hz yam tsis muaj kev hloov kho.

38dB rau pem hauv ntej nce, 27dB thim rov qab nce.
Pab kom siab rau pem hauv ntej bandwidth mus txog 1220 MHz
42/54, 85/102, 204/256MHz muaj diplex lim xaiv.
Aluminium Chassis muab cov cua kub zoo heev.
Qhov sib txawv attenuators thiab equalizers.
-20dB sab nraud inpuVoutput xeem cov ntsiab lus.
Surge tiv thaiv txog 6kV / 3kA ntawm IN / OUT cov chaw nres nkoj.
100-240VAC sab hauv hloov hluav taws xob.
