GPV 845 C and GPV 845 CF are multimedia
enabled house connection amplifiers for
medium to large-sized building units. They are
used to balance out the cable and distribution
attenuation in the CATV domestic networks.
“All on board” - all of the important function
units, such as preamplifier, diplex filters,
return channel amplifiers and the associated
actuators are completely implemented on
board.
The amplifier is configured for the specific use
using jumpers in the device and can be done
both during installation and during operation.
i Simple migration of the return channel without additional modules”. Either “TV band I” or
“Return channel 65 MHz” can be selected.
Adjustable return channel:”active”/”passive”/”off”, optimum adjustment of the
reverse channel amplification (C/N) by means
of adjustable attenuators at the input and
output.
i Advanced long term stability due to discrete,
switchable attenuators and equalizers i.e. no
usage of spin regulators or a large number of
plug-in pads
i High output level with extremly low power
consumption thanks to MMIC GaAa-Push-Pull
output stage and switching power pack with
high degree effectiveness
i Long life cycle thanks to low temperature
development due to low power consumption
and the die cast housing with cooling units.
i Power supply GPV 845 C local feeding from
230 V domestic network
i Power supply GPV 845 CF remote feeding
from the coaxial network
i Options on request
Return path 5...30 MHz,
RF input 5/8’’ for remote feeded device,
second RF output with tap
