GHV 845 E
Frequency range MHz
GPV 845 E is a variant of the highpower GPV 845 house connection
amplifier family, especially equipped for
MATV installations with local SMATV
headends that do not provide any
interactive services via this network.
Gain forward
Features:
• Only the forward path - including
VHF band I is implemented
• Level adjuster and line equaliser
with potentiometers.
• High output level at extremely
low power consumption through
MMIC GaAs push/pull output stage
and switched-mode,
high-efficiency
Power supply:
• Local supply from 230 V domestic
network
• Compatible with standards
EN 60065, EN 50083-1,
EN 50083-2, Class A
