CATV Amplifier (GF-8055R)
Features:
¡ï Imported amplifying module to amplifying RF signal and send it into distribution network. Silicon and GaAs amplifying module effectively enhance non-linearity parameter, output capability and decrease noise figure
¡ï Two-way modularizing designing, including forward channel, return channel, Send back upstream RF or data signal can be sent to optical node . User configurable, defaulted forward channel
¡ï 862MHz platform design, 550 MHz, 750 MHz, 862 MHz compatible, easy online upgrade
¡ï Fittings for amplifier( attenuator, equalizer, two-way filter) adopt plug-in type, adjustable and fixed attenuator and equalizer
¡ï RF level test port for input and output
¡ï Pre-distortion for equalizer, effectively eliminate bulge phenomenon
