All on board!
Flexible. Reliable. Economical.
GPV 845C and GPV 845CL are multimedia-enabled
house connection amplifiers for medium-sized to large
building units. It is used to balance out the cable
distribution attenuation in CATV domestic networks.
“All on board”– all of the important function units, such
as preamplifier, diplex filters, return channel amplifier
and the associated actuators are completely
implemented on the circuit board.
The amplifier is configured by jumpers in the device
and can be done both during installation and during
operation.
ROB - “return path on board”
without additional modules
“TV band I” (RC off) or “Return channel 65 MHz”
selectable.
Adjustable return channel: “active”/”passive”/”off”.
Optimum adjustment of the return channel
amplification by means of jumper attenuators at the
input and output.
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
High output level with extremely low power consumption
Due to MMIC GaAs-Push-Pull output stage with
highly effective switching power supply with high
degree of effectiveness
Long life cycle
Low temperature development (low power
consumption and die-cast housing with cooling fins),
extensive ESD and surge protection
