GHV 820 A and GHV 830 A are multimedia enabled house connection amplifiers for small to
medium-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 with
ROB-”return channel options on board”.
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 Multi emitter transistor amplifier on a 1-GHz
platform with low energy consumption
i Long life cycle thanks to low temperature
development due to low power consumption
and the die cast housing with cooling units.
i Spin potentiometers for easy adjustment
