House connecting amplifier
Description
Multimedia capability house
connecting amplifier for me-
dium-sized to large building
units. All of the important func-
tion units, such as preamplifier,
diplex filters, return channel
amplifier and the associated
actuators are completely imple-
mented on the circuit board

board. The amplifier is configu-
red for the specific use by using
jumpers - can be done both
during installation and during
operation.

• Advanced long-term
stability due to discrete,
switchable attenuators
and equalizers (i.e. no
usage of spin regulators)
• Internal test socket at
input and output.
• High output level with
extremely low power
consumption thanks to
MMIC GaAs-Push-Pull
output stage and swit-
ching power pack with
high degree of effective-
ness
